The purpose of the invention is to more reliably suppress a phenomenon in which a Taumel-type movement is generated during reclining angle adjustment, and a seat back gradually falls down during locking. When the reclining angle is stopped, divided gears 221 of a second disk-like gear 22 are pressed in the direction of meshing with internal teeth 10a by a cam 220 arranged at the rotation center of the divided gears 221. A rotational force that cause the divided gears 221 to rotate outward around one support pin 26 is generated in the divided gears 221, and at the same time, a pressing force causing the divided gears 221 to be pressed outward in the radial direction is generated by a cam 220. Since external teeth 221e of the divided gears 221 are engaged with the internal teeth 10a of an internal gear 10 in a state where such rotational force and pressing force are generated, backlash between both gears is also reduced.

HEAD BIOLOGICAL SIGNAL DETECTION DEVICE AND BIOLOGICAL STATE ESTIMATION DEVICE
With a simple structure, to make it possible to detect a head biological signal that reflects the state of cerebral blood flow, and to make it possible to assess a sleep stage based on a variation in the cerebral blood flow. A head biological signal detection sensor is supported on the head using a sensor support member such that a connecting yarn sags to make an interval between a pair of facing ground knitted fabrics in a three-dimensional knitted fabric narrower than that under no load. With this configuration, microvibration occurring in yarns and fibers forming the three-dimensional knitted fabric of the head biological signal detection sensor or in other places due to head movement resulting from body motion or the like generates stochastic resonance, which makes it possible to detect a head biological signal.
Through biological signal data analysis, heart rate variability information is found and represented on log-log axes, a quartic function is set for a waveform resulting from analysis of the information, and one of two types of gradient values obtained based on different criteria, i.e., a gradient (GI) between points of inflection and a gradient (GT) of a tangent at a point of inflection (a GI value and a GT value), is employed as a final analysis result, depending on the number of extreme values in the quartic function. A cardiac output influenced by two factors, i.e., nervous system regulation which influences a heart rate and an arterial blood pressure which influences a stroke volume, undergoes increases/decreases due to the respective two factors. However, owing to the employment of one of the GI value and the GT value, an increase/decrease in the influence of each of these two factors is reflected.
The present invention estimates, with high accuracy, the blood pressure from a single physiological index such as the heart rate. In the present invention, when setting a quartic polynomial expression, a boundary frequency that divides between a non-periodic component and a periodic component is extracted from a log-log graph, and then, from an approximate curve indicated by the quartic polynomial expression set in either a lower frequency band or a higher frequency band located across the boundary frequency, a frequency gradient thereof is determined. By setting an approximate curve indicated by a quartic polynomial expression for each of the bands located across the boundary between the non-periodic component and the periodic component while the log-log graph is being displayed, it becomes possible to determine the frequency gradient in a form that matches intravascular pulsation, thereby making it possible to increase accuracy of a blood-pressure value.
Provided is a technology for determining a circulatory system physiological index serving as an index for estimating blood pressure with higher accuracy. A power spectrum is found by performing frequency analysis of the time-series data of the fluctuations of an instantaneous heart rate, and the power spectrum is displayed by being plotted on a log-log graph. With respect to the plot display, a plurality of types of frequency bands to be analyzed are set, and two types of approximate curves having different orders are applied. As each approximate curve, found are a plurality of curves that are indicated by fourth-order polynomials or third-order polynomials for which the residual standard-deviation with respect to the plot display of the power spectrum is minimized. The smaller the residual standard-deviation is for an approximate curve, the greater the correlation between blood pressure and the frequency of the inflection point of the approximate curve; therefore, on the basis of the foregoing, an approximate curve having a higher correlation with blood pressure is selected. A residual standard-deviation is also calculated for tangent lines of inflection points and straight lines between inflection points of each of a plurality of approximate curves, and the minimum residual standard-deviation is applied.
To improve the stability of a posture when seated by improving the supporting property of the pelvis. A seat structure (1) has a support plate (43) that is biased forward as a pelvis support mechanism (4), and supports the pelvis of the seated person. The physiological curvature of the spinal column is easily maintained, and the shoulder blades are easily brought into contact with the upper part of the backrest, allowing the stable seating posture to be easily maintained. The support plate (43) is biased forward and is configured to be displaceable in a rotation direction in a plan view, that is, in a rotation direction centered on the torso of the seated person. During the ride, the pelvis and the shoulder blades are suppressed from being significantly separated from the backrest, enhancing the stability of the posture.

The present invention estimates, from one physiological index such as heart rate, another physiological index such as blood pressure with high accuracy. A physiological index estimation device 100 constructs a three-dimensional response surface model defined by a two-dimensional n-th order polynomial in which measurement data of heart rate and a circulatory dynamics variation index are used as explanatory variables and a blood pressure value is used as an objective variable. Additionally, the physiological index estimation device obtains a circulatory dynamics variation index obtained from the measurement data of the heart rate obtained from an estimation target subject, and estimates the blood pressure value of the subject. By using the three-dimensional response surface model, it is possible to grasp more accurately the correlation, in which the complexity is controlled, among the one physiological index, the circulatory dynamics variation index, and the other physiological index, to thereby improve the estimation accuracy.

BIOLOGICAL SIGNAL ANALYSIS DEVICE, COMPUTER PROGRAM, AND RECORDING MEDIUM
To make it possible to grasp a biological condition, in particular, a condition ascribable to the movement of the heart. According to the embodiments, it is possible to find a boundary frequency between cardiac apex beat and heart sound. This makes it possible to find not only heart sound, but also cardiac apex beat, from a biological signal which is a collection of biological sound and in-vivo vibration. The boundary frequency is represented by a quadratic function of heart rate, and the use of correlation data based on the quadratic function makes it possible to find heart rate or a boundary frequency in real time. As a result, for example, if heart rate is known, the level of a boundary frequency is known. This facilitates inferring a health condition, for example, whether or not the heart is under stress, from a broader viewpoint than conventionally.
The present invention applies an appropriate damping force which corresponds to a relative displacement amount. One member among a first member 10 and a second member 20 which are provided so as to be capable of relative movement is provided with a three-dimensional fabric 31, 32 in a manner such that the clearance C relative to the other member in a direction which is perpendicular to the movement direction of the members partially changes in said movement direction. As a result, the relative positions of the first member 10 and the second member 20 cause a change in the compression amount of the three-dimensional fabric 31, 32 which is caused by compression members 51, 52, causing a change in the sliding resistance acting therebetween. Consequently, it is possible to set various properties for the damping force, which is produced when the first member 10 and the second member 20 move relative to one another, by adjusting the clearance C between the three-dimensional fabric 31, 32 and a member among the first member 10 and the second member 20.

The purpose of the present invention is to improve the accuracy of estimation of a biological state associated with a blood pressure. A biological signal data is analyzed to determine heartbeat fluctuation information on log-log axes, a quartic function is prescribed for a waveform obtained by the analysis, and either one of two gradient values (a GI value and a GT value) obtained based on different criteria, i.e., a gradient (GI) between points of inflection and a gradient (GT) of a tangent line at a point of inflection, is employed as a final analysis result depending on the number of extreme values in the quartic function. A cardiac output is affected by two factors, i.e., the regulation of a nervous system which affects a heart rate and an arterial blood pressure which affects a single cardiac output, and is increased or decreased with respect to the two factors. However, when either one of the GI value and the GT value is employed, the increase or decrease in the amount of influence of these two factors is reflected.

HEAD BIOLOGICAL SIGNAL DETECTION DEVICE AND BIOLOGICAL STATE ESTIMATION DEVICE
The present invention makes it possible to detect, with a simple structure, a head biological signal that reflects the state of cerebral blood flow and to assess a sleep stage based on variations in the cerebral blood flow. A head biological signal detection sensor (10) is supported on the head using a sensor support member (20) by causing a connecting yarn to sag in such that the interval between a pair of opposing ground knits in a three-dimensional knit (11) becomes narrower than without having a load. With this configuration, it becomes possible to detect head biological signals by generating stochastic resonance by micro vibration occurring, in association with head motion resulting from body motion or the like, in yarns, fibers, or the like forming the three-dimensional knit of the head biological signal detection sensor.
A biological signal detection device is capable of accurately and simply measuring biological signals and promotes daily health care. A body abutting-side cushioning member 10 formed of a three-dimensional knitted fabric is substantially circular in plan view. A base cushioning member 20 is also substantially circular in plan view. A square one tends to undergo deformation such as turning-up or folding of its edges around the corners when, for example, a person sits thereon. Such deformation tends to distort detection data. Moreover, the folding and the like give a feeling of something foreign. In contrast, a substantially circular one less undergoes such folding and the like.
The present invention suppresses a half lock state by reducing operation resistance. This lock mechanism (16) includes a base plate (1621) supported on a shaft (161) suspended down from an upper wall section (12a) of an upper rail (12), and has a lock plate (163) which is vertically displaceable between the upper wall section (12a) and the base plate (1621). The lock plate (163) is vertically biased by an engagement spring section (1622), and the front end edge and the rear end edge thereof are elastically supported in a slide direction by a spring section (1623) for front-rear support. A lever spring member (165) which biases a release lever (164) is separately provided. The spring force of the lever spring member (165) linked to the release lever (164) does not act on the lock plate (162), and the spring force of the engagement spring section (1622) directly acts when biasing the lock plate (163) in the lock direction, thereby making it possible to suppress a half lock state.

BIOLOGICAL SIGNAL ANALYSIS DEVICE, COMPUTER PROGRAM, AND RECORDING MEDIUM
The purpose of the present invention is to identify a biological state, particularly a state associated with the movement of the heart. According to the present invention, a boundary frequency between a cardiac apex beat and a heart sound can be determined. Therefore, it becomes possible to identify a heart sound as well as a cardiac apex beat from a biological signal that is a collected entity of a biological sound and an oscillation in a body. The turning frequency is expressed by a quadratic function of a heart rate, and a heart rate or a turning frequency can be identified in a real-time basis by utilizing correlation data obtained from the quadratic function. As a result, when a heart rate is known for example, the level of a turning frequency can be known, and consequently the change in health condition, e.g., a matter as to whether or not a strain is put on the heart, can be estimated easily from a broader viewpoint compared with the conventional methods.

Provided is a mask through which it is easy to breathe despite enhancing the capacity of a facepiece to inhibit the passage of airborne particles. The facepiece 100 has an outside layer 110, an intermediate layer 120, an inside layer 130, and an outside layer-adjacent section 140 joined to the upper edge 112 of the outside layer 110. The inside layer 130 and the outside layer-adjacent section 140 are both formed from a three-dimensional fabric. The inside layer 130 and the outside layer-adjacent section 140 partially overlap, and a flow path for air is formed between the two components formed from the three-dimensional fabric. In this way, the ease of breathing is not compromised because the flow path for air via the outside layer-adjacent section 140 and the inside layer 130 is maintained despite using a mask in which the capacity of the outer layer 110 and the intermediate layer 120 and especially the intermediate layer 120 to inhibit the passage of airborne particles is high, in other words, a mask in which the capacity to capture airborne particles and block the passage thereof is high.
There are provided a biological signal measurement device capable of obtaining a variety of biological information and applicable also to medical fields and the like, a biological state inference device, and a biological state inference system using these. The biological signal measurement device 1 of the present invention includes three biological signal detection units, namely, a left upper part biological signal detection unit 11, a right upper part biological signal detection unit 12, and a lower part biological signal detection unit 13. The biological state inference device 1 is capable of obtaining a highly precise inference-use processed waveform from which electrical noise has been removed, by using an appropriate combination of time-series data obtained from the three biological signal detection units 11 to 13. Because the precision of an inference-use processed waveform corresponding to target biological information on breathing, heart sound, or the like increases, the precision of inferring a biological state also increases.

Blood pressure estimation device, blood pressure estimation method, computer program, and storage medium
Blood pressure is estimated in a non-constraining manner continuously and in real time. A biological signal collected from a person's dorsal part is analyzed, vibration in the human body ascribable to a blood flow rate change in a period from the ventricular filling period to the isovolumetric systole is captured, and the state of fluctuation of an index indicating the state of the in vivo vibration is further captured. This fluctuation index correlates with a person's blood pressure. Therefore, it is possible to estimate whether the blood pressure is in a range indicating a normal-range blood pressure or in a range indicating a high blood pressure, only by having the person sit or lie supine on a surface provided with a biological signal measurement device to measure a biological signal in a non-constraining manner, so as to make the biological signal measurement device contiguous with the person's dorsal part.
A damper includes: a line-shaped member wound around an outer peripheral surface of a piston which makes a relative motion in a cylinder; and a viscous fluid made to adhere to the line-shaped member and exhibiting viscous damping force. The relative motion of the cylinder and the piston produces tension, and in the line-shaped member, as an amplitude is smaller, its contiguously wound portions each try to deform to twist along a circumferential direction of the line-shaped member itself, and as the amplitude is larger, the contiguously wound portions try to deform as a unit. When the amplitude is small, frictional resistance decreases, resulting in smooth motion of the piston, and appropriate damping force is obtained due to the viscous damping force of the viscous fluid. When the amplitude is large, as a result of the increased tendency that the contiguously wound portions of the line-shaped member try to deform as a unit, friction damping force acts relatively greatly.

A seat cushion part includes a base fabric extending between and looped around a front edge frame and a rear edge frame, and having an upper layer part and a lower layer part which are provided apart from each other in an up-down direction. Wire members of metal are provided respectively on side edge portions of the base fabric, and coil springs are spring members each extending between an end portion of the wire member and the front edge frame or the rear edge frame. A load further applied due to vibration, impact, and so on causes the upper layer part to come into contact with the lower layer part to also displace the lower layer part in the up-down direction. Consequently, the coil springs connected through the wire members extend/contract, and their elastic force acts.
In order to continuously estimate blood pressure in a non-constraining manner and in real time, the present invention is configured to analyze a biological signal collected from a person's dorsal part, captures vibrations in the body (in vivo vibrations) generated by changes in blood flow between the ventricular filling period and the isovolumetric contraction period, and further captures fluctuations in an index (index relating to fluctuations [fluctuation index]) indicating the state of the in vivo vibrations. The fluctuation index is associated with information relating to the person's condition, in particular the person's blood pressure, as described above. On the above basis, the present invention makes it possible to easily estimate a person's blood pressure, and in particular, whether the blood pressure is within a normal blood pressure range (diastolic blood pressure of less than 90 mmHg, systolic blood pressure of less than 140 mmHg) or in a high blood pressure range, by simply having the person sit or lie supine on a biological signal device that can measure a biological signal in a non-constraining manner and is attached to a vehicle seat, a chair for home, office or other uses, sleeping equipment such as a bed, or the like so that the biological signal device is contiguous with the person's dorsal part.

The purpose of the present invention is to improve vibration damping characteristics or shock-absorbing characteristics vis-à-vis impact vibrations over those of conventional devices. A suspension mechanism 1A of the present invention has a structure wherein multiple spring-damper-equipped suspension units 100, 300 having spring mechanisms 120, 320 and dampers 130, 330 are stacked vertically. Therefore, the spring mechanisms 120, 320 are connected vertically in a series and the natural frequency can be lower than in a system with a single-layered spring-damper-equipped suspension unit, helping to place the resonance point more towards the low frequency. Furthermore, there is greater likelihood of phase difference being generated by individual movements of the spring-damper-equipped suspension units 100, 300 concomitant with input vibration difference, thereby enabling efficient inhibition of vibration transmission rate at the resonance point.
A seated person's orientation stability with respect to input vibration can be improved, and vibration-absorbing characteristics, or impact-absorbing characteristics derived from impacting vibration, are improved over the prior art. This suspension mechanism is structured such that two suspension sections (100, 200), in which a movable support part (140) and a seat support part (240) are supported through respective link mechanisms (110, 210), are disposed in two levels, one above the other, and the suspension mechanism is configured such that when the movable support part (140) and the seat support part (240) move vertically relative to each other in accordance with input vibration, the two link mechanisms (110, 210) supporting these parts rotate in mutually opposite directions. Therefore, the hip point position of a person seated in the seat supported on the seat support part (240) shifts in a nearly vertical path, forward-backward shaking is reduced to less than when one link mechanism is used, seated orientation stabilizes, and the ride is smoother.
A surface fastener formed of a synthetic resin and in which a base with a 0.1 to 0.9 mm thickness and engagement element groups including engagement elements with a 0.2 to 0.8 mm protrusion height are integrally molded, and engagement element rows are composed of the plural engagement elements arranged in a row direction and each protruding independently. A cushioning member is covered with a covering member via the surface fastener. A resistance value of the surface fastener by itself as measured by a handle-o-meter method conforming to the JIS L 1096 E method is 80 to 150 g, whereas a load-deflection characteristic when a pressure is applied to an overlapping portion of the stacked surface fastener and cushioning member by a pressure plate with a 30 mm diameter approximates a similarly measured load-deflection characteristic of the cushioning member by itself.

The present invention is capable of applying a damping force greater than in the prior art and achieves a further reduction in thickness. A damper 60 is provided on the upper frame 10 side so as to serve as a sub vibrating body, the upper frame 10 serving as a main vibrating body which is supported by the top of the front link 21 and the rear link 22 of a frame link mechanism 20, and the sub vibrating body generating vibrations with behavior different from the vibrations of the upper frame 10 generated by the rotary movement of the front link 21 and the rear link 22. When the upper frame is vibrated by input vibration, the energy of the input vibration is not only distributed as vibrational energy of the upper frame 10 and heat energy generated by the expansion and contraction of the damper 60 but is also consumed as energy for vibrating the damper 60 itself, which is provided as a vibrating body, due to the different vibrational behavior exhibited thereby. This arrangement structure of the damper 60 improves the basic performance of vibrational absorption characteristics and shock-absorbing characteristics of the suspension.

A power seat sliding apparatus is provided which has a superior noise suppression effect and temperature increase suppression effect in a gear mechanism. The gear mechanism 30 is provided with a case 310 which pivotably supports a worm 320 and a worm wheel 330, and the case 310 is suspended from and supported by an upper rail 12. The worm 320 is linked to and supported by a rotational force transmitting shaft 220 of a drive mechanism 20, and the worm wheel 330 is screwed onto and supported by a slide screw 11a provided on the lower rail 11. Further, the case 310 is supported on the lower rail 11 via a ball 340 as a rolling member. By this means, sliding operations of the case 310 itself are stable, and it is possible to better achieve the noise suppression effect.

In order to make the elastic action and damping characteristics function in a balanced manner, and to contribute to further improvement of vibration absorption characteristics and shock absorption characteristics, of which vibration absorption characteristics are foremost, this seat cushion 10 is configured provided with a base fabric 107 which is wrapped in a loop shape between a front edge frame 101 and a rear edge frame 102 and which has an upper layer 1071 and a lower layer 1072 disposed with a vertical gap therebetween; a metal wire material 1073 is provided on each lateral edge of the base fabric 107, and coil springs 108, 109 are provided as spring members between each end of each wire material 1073 and the front edge frame 101 or the rear edge frame 102. In the case of an additional load from vibration, impact, etc., the upper layer 1071 contacts the lower layer 1072, and the lower layer 1072 is also vertically displaced. Thus, the coil springs 108, 109 connected via the wire materials 1073 expand and contract, resulting in action of the elastic force thereof.

Appropriate damping force that corresponds to a relative displacement amount is exerted by a simple structure. This damper has a wire member 32 wound around the outer peripheral surface of a piston 3 that undergoes relative motion within a cylinder 2, and a viscous fluid that adheres to the wire member 32 and exhibits viscous damping force. Tensile force is generated by the relative motion of the cylinder 2 and the piston 3. At lesser amplitudes, the wire member 32 deforms so that adjacently wound sections twist along the circumferential direction of the wire member 32, whereas at greater amplitudes, there is a greater tendency for the wire member 32 to deform so that adjacently wound sections are integrated. At low amplitudes, the motion of the piston 3 is smooth due to decreased friction resistance, and appropriate damping force is attained through the viscous damping force of the viscous fluid. At high amplitudes, there is a greater tendency for the adjacently wound sections of the wire member 32 to deform integrally, and the effect of frictional damping force becomes relatively greater.

The present invention prevents a three-dimensional fabric arranged in front surfaces of speakers from flapping due to sound. In the respective front surface sides of, sound-emitting direction regulating members that include annular portions that project forward by a predetermined distance are arranged. A three-dimensional fabric is tensioned and arranged so as to cover the front surface sides of the sound-emitting direction regulating members. When the three-dimensional fabric is pressed against the annular portions configuring the sound-emitting direction regulating members, the annular portions bite into the three-dimensional fabric since the three-dimensional fabric has a predetermined thickness. The annular portions are provided so as to surround diaphragms of the speakers. Sound output from the speakers passes inside the annular portions. However, the periphery of a region of the three-dimensional fabric in which sound passes is supported by the biting of the annular portions, thereby preventing the three-dimensional fabric from flapping widely in response to the sound.

A back cushioning member having a tensile structure to reduce discomfort of a seated person. A lower lumbar support 10 installed in a lower portion of a back frame 111 and an upper lumbar support 20 installed in an upper portion of the lower lumbar support 10 are provided. Having vertically two lumbar supports 10, 20 enables a first support plate 12 of the lower lumbar support 10 to be provided so as to correspond mainly to a pelvis part where the sense of contact is hardly perceived, whereby the back cushioning member 112 having a tensile structure can be provided with a predetermined restoring force at a predetermined applicable elastic strength. Since the pelvis part located at a lower portion of a human body can be supported reliably, prevention of collapse of posture can be facilitated. Since the upper lumbar support 20 corresponds mainly to a lumbar part, by setting the upper lumbar support 20 to provide a softer springiness than the lower lumbar support 10, the sense of contact in the lumbar part is suppressed and the feeling during seating can be improved.

A torque transfer control mechanism that suppresses output-side displacement, and including a rotation control unit that maintains a locked state when an input torque rotating a transfer mechanism is not applied, and releases the locked state when the transfer mechanism rotates. The rotation control unit includes an internal gear and lock plates that include outer teeth that can engage with inner teeth of the internal gear. When an input torque is not applied, the inner teeth of the internal gear engage with the outer teeth of the lock plates, and when the transfer mechanism is rotated, engagement between the inner teeth and the outer teeth is released. Thus, even when torque is applied from the output unit side, engagement between the inner teeth and the outer teeth is not released by the torque.

A structure in which two worm wheels are disposed across a worm provides an increase in locking reliability while maintaining stable operation during rotation. At the time of rotation, respective rotating fulcrums set at both end portions in an axial direction of a worm are supported by bearing parts. At the time of locking, a locking fulcrum set at an eccentric position on one end portion in the axial direction of the worm is supported by one bearing part, while on the other end portion in the axial direction, the rotating fulcrum is supported by the other bearing part as is. As a result, the angle of lead of the worm supported by the pair of bearing parts is changed between the time of rotation and the time of locking and becomes smaller at the time of locking than at the time of rotation, whereby an increase in locking reliability can be achieved.

Seat cushioning member support mechanism and seat structure
A sheet cushioning member includes front links coupled to a front torsion bar and rear links coupled to a rear torsion bar are arranged at a predetermined interval from each other in a front and rear direction of a seat, and when a predetermined load or larger is applied, the front links and the rear links rotate in opposite directions, and dampers are disposed to extend between lower portions of the front links and the rear links. When a predetermined load fluctuation or larger occurs, the dampers expand or contract to exhibit a damping force, and a load fluctuation smaller than this does not cause the dampers to expand or contract and is alleviated by elasticity of the front torsion bar and the rear torsion bar. An impact absorbing characteristic is thereby improved with a simple structure.

A reinforcing structure in a substantially rectangular frame shape is set in an area where cushion-part side frames and back-part side frames are coupled to each other via reclining mechanism parts, from vicinities of rear portions of the cushion-part side frames up to vicinities of lower portions of the back-part side frames. The reinforcing structure increases unity of a cushion frame and a back frame, and when a load is applied to the back frame due to an impact at the time of a rear-end collision or the like, the load acts as a force deforming mainly the cushion frame via the reinforcing structure, and when the body of a seated person thereafter moves rearward, the load acts as a force deforming mainly the back frame, making it possible to use not only strength of the back frame but also strength of the cushion frame.

The purpose of the present invention is to reduce the occurrence of noise caused by play between constituting parts. Rolling members 80 are arranged between surfaces of lock plates 60A-60D operating radially between guide walls 23a-23d and surfaces of the guide grooves 23f-23i of a guide bracket 20, the surfaces of the lock plates 60A-60D and the guide grooves 23f-23i facing each other. When force which rotates the guide bracket 20 and an internal gear 30 relative to each other is applied in a locked state in which the outer teeth 63 of the lock plates 60A-60D and the inner teeth 32 of the internal gear 30 are meshed with each other, the rolling members 80 function as wedges. The lock plates 60A-60D are pressed in the direction in which the lock plates 60A-60D are in contact with side surfaces of the guide walls 23a-23d, thereby reducing the operational clearance between the lock plates 60A-60D and the guide walls 23a-23d and thus reducing the circumferential play of the lock plates. The facing surfaces of the guide grooves 23f-23i and of the lock plates 60A-60D are pressed relative to each other to reduce the operational clearance between the lock plates 20 and the guide bracket 30 in a stack direction, thereby also reducing play in the stack direction.

To enable an output sound of a speaker unit to be output as a surface sound source in a limited space. A three-dimensional knitted fabric is provided at a position substantially facing speaker units while being given tension in a surface direction. Since the tension is applied, a pair of ground knitted fabrics constituting the three-dimensional knitted fabric and a connecting yarn extending back and forth between the ground knitted fabrics vibrate due to their elastic action. In particular, string vibration is generated in the connecting yarn. Due to this vibration, output sounds of the speaker units are propagated in the surface direction of the three-dimensional knitted fabric, and as a result, the three-dimensional knitted fabric propagates and radiates acoustic waves of a surface sound source.

Provided is a headrest in which a pad layer is integrally formed, including a section with a narrow gap, between a mechanism having various built-in functions and an upholstery member. Set inside an upholstery member (50) is an impact-absorbing member (30) that is an injection-passage-forming member having a foaming raw material injection passage (311) formed so as to run substantially along a direction that is the vertical direction of the headrest in an orientation assumed when the seat is attached, and a foaming raw material for forming the pad layer is injected through the foaming raw material injection passage (311). The configuration preferably causes the foaming raw material to spread up until the start of the foaming because the foaming raw material spreads to the outer side of the headrest (10), i.e., to the inner surface of the upholstery member (50), where the pad layer must be formed. Therefore, the pad layer is reliably formed between the inner surface of the upholstery member (50) and the outer surface of the impact-absorbing member (30) when foaming begins after the foaming raw material has spread.
A neck injury is improved with a structure having a lifting mechanism part only on one side. While a lifting driving part is provided on a side of one side frame, a coupling driving rod is coupled to a rotation center of a drive gear a driving link is disposed on a side of the other side frame, and the driving link is coupled to the coupling driving rod. A driving force in the lifting driving part operates on the side of one side frame having the drive gear, but on the side of the other side frame, the driving link rotates together with the drive gear via the coupling driving rod, so as to perform a lifting or lowering operation. The shape of a virtual square coupling contact points of the driving link, the side connectors, the coupling driving rod, and the drive gear does not collapse, and thus an external input is dispersed.

A rotating movement control mechanism including a worm, and a main driving side worm wheel and a driven side worm wheel disposed across the worm. Both end portions of the worm in an axial direction are axially supported by bearing parts. Respective teeth of the main driving side worm wheel and the driven side worm wheel contact both sides of the worm in a direction substantially orthogonal to the axial center with a backlash, and are supported thereby. When the second member is relatively rotated with respect to the first member, the worm rotates relatively with respect to the main driving side worm wheel. The driven side worm wheel rotates by a rotational force of the worm, and a rotational force of the driven side worm wheel is regenerated in the worm. Whirling vibrations of the worm are suppressed, and relative rotation is performed smoothly.

In order to easily infer the risk of sleep-related disease including sleep apnea syndrome, the present invention analyzes biological signals collected by a biological signal measurement device, determines the timing of appearance of fatigue, decrease in attentiveness, or a predetermined decreased state of wakefulness including sleepiness, calculates the number of appearances thereof per unit time, and estimates the risk of disease related to sleep from the relationship between the calculated number of appearances and a circadian rhythm of sleepiness.
A power seat slide device capable of changing not only to an electric operation but also to an manual operation, and preventing half-lock in spite of a manually operable structure. For front-rear movement, a rack attached to a lower rail and a pinion meshed with the rack are used, and a driving force of a motor is transmitted to the pinion, which enables the use in an electric mode. As no slide screw is used, while the motor is not energized, rotating the pinion causes an output shaft of the motor to rotate, so that manual adjustment becomes possible.

The present invention more reliably suppresses output-side displacement in comparison with conventional mechanisms. The present invention is provided with a rotation control part 120 which maintains a locked state when an input torque rotating the transfer mechanism 110 is not applied, and which releases the locked state when the transfer mechanism is rotated. The rotation control part 120 has an internal gear 124 and a lock plate 123 which has outer teeth that can be engaged with internal teeth of the internal gear 124. When an input torque is not applied, the inner teeth of the internal gear 124 are engaged with the outer teeth of the lock plate 123, and when the transfer mechanism 110 is rotated, the engagement of both the internal and outer teeth is released. Thus, even if torque is applied from the output side, the engagement of both the internal and outer teeth is not released by the torque.

SEAT SUPPORT MECHANISM, SEAT STRUCTURE AND SUSPENSION SEAT
According to the present invention, a cushion frame exhibits a suspension function even when the cushion frame is adjusted to any height while a lifter is attached thereto. Torsion bars 330, 340, which are disposed across a cushion frame 10 in the widthwise direction of the cushion frame 10 and which elastically support the cushion frame 10, are supported by a link mechanism 40 which is disposed between a slider 20 and the cushion frame 10. Even when the posture of the link mechanism 40 is displaced by a height adjustment of the lifter 30, the positions of the torsion bars 330, 340 are displaced accordingly. Even when the torsion bars 330, 340 are displaced to any height, there is no change in the elastically supporting of the cushion frame 10 by the torsion bars 330, 340. Therefore, the torsion bars 330, 340 can support the cushion frame 10 with a predetermined elasticity and can exhibit a predetermined vibration absorption characteristic, regardless of the height to which the torsion bars are adjusted.

The purpose of the present invention is to be suitable as a back cushioning material having a tensile structure and to reduce discomfort of a seated person. A lower part lumbar support 10 arranged in the lower part of a back frame 111 and an upper part lumbar support 20 arranged above the lower part lumbar support 10 are provided. Having two (upper and lower) lumbar supports 10, 20 enables a first support plate 12 of the lower part lumbar support 10 to be positioned so as to mainly correspond to a pelvis area where the sense of contact is hardly perceived, whereby the cushioning member 112 having a tensile structure can be provided with a predetermined restoring force at a predetermined applicable elastic strength. Since the pelvis area positioned at a lower part of a human body can be supported securely, suppression of collapse of posture can be facilitated. Since the upper part lumbar support 20 mainly corresponds to a waist area, by setting the upper part lumbar support 20 to provide a softer springiness than the lower part lumbar support 10, the sense of contact in the waist area is suppressed and the feeling during seating can be improved.
A structure in which two worm wheels are disposed across a worm provides an increase in locking reliability while maintaining stable operation during rotation. At the time of rotation, respective rotating fulcrums set at both end portions in an axial direction of a worm 50 are supported by bearing portions 510, 520. At the time of locking, a locking fulcrum set at an eccentric position on one end portion in the axial direction of the worm 50 is supported by one bearing portion 510, while on the other end portion in the axial direction, the rotating fulcrum is supported by the other bearing portion 520 as is. As a result, the angle of advance of the worm supported by the pair of bearing portions 510, 520 is changed between the time of rotation and the time of locking and becomes smaller at the time of locking than at the time of rotation, whereby an increase in locking reliability can be achieved.

A seat suspension with a compact structure while being capable of coping with input vibrations not only in a vertical direction but in six-axis directions. Three pantograph links between a vehicle body floor side and a seat side are employed. Thus, control in six-axis directions is possible, allowing simplification compared to conventional structures. In addition to an active control mechanism using the pantograph links, the seat suspension has a compressed coil spring and the magnetic spring as a first elastic member and a second elastic member. Specifically, damping is performed with high efficiency by controlling the seat side in a reverse phase to the vehicle body floor side with respect to the input direction of vibrations by the active control mechanism and meanwhile performing damping passively by these elastic members.

An objective of the present invention is to improve shock absorbing characteristics over conventional technology with a simple configuration. Provided is a seat cushion support mechanism, in which fore links (211, 212) which are coupled to a fore torsion bar (210) and aft links (221, 222) which are coupled to an aft torsion bar (220) are disposed in the fore-aft direction of a seat with a prescribed interval therebetween, such that the fore links (211, 212) and the aft links (221, 222) rotate in the reverse direction when a load which is greater than or equal to a prescribed load is applied thereupon, and dampers (230) are positioned between the lower parts of the fore links (211, 212) and the aft links (221, 222). When a load fluctuation greater than or equal to a prescribed load fluctuation occurs, the dampers (230) stretch and an attenuating force takes effect. A smaller load fluctuation is eased by the elasticity of the fore torsion bar (210) and the aft torsion bar (220), without the dampers (230) being stretched.

The present invention addresses the problem of providing a seat structure of high strength. A structure of the present invention is such that in an area from around rear portions of cushion-side side frames (11) to around lower portions of back-side side frames (21) where the cushion-side side frames and the back-side side frames are linked via reclining mechanism portions (30, 30), a substantially rectangular-frame shaped reinforcing structural body (110, 120, 130) is set. The reinforcing structural body (110, 120, 130) increases the integrity of a cushion frame (10) and a back frame (20), whereby, when a load is applied to the back frame by the shock of a rear collision and the like, the load will mainly act as a force that would deform the cushion frame (10) via the reinforcing structural body (110, 120, 130), and the load will thereafter act as a force that would mainly deform the back frame (20) as the body of a seated person moves rearward. When subjected to the shock load of a rear collision and the like, the structure can take advantage of not only the strength of the back frame (20) but also the strength of the cushion frame (10), providing higher rearward moment strength than is offered conventionally.

SURFACE FASTENER, CUSHION STRUCTURE, AND SEAT STRUCTUREX
A surface fastener that does not feel foreign to people when arranged and which has higher engagement force in the shear direction than conventional surface fasteners. A synthetic resin surface fastener (100) is used that: has integrally formed therein a substrate (110) having a thickness of 0.1-0.9 mm and engagement element groups (120, 130, 140) including engagement elements (121a, 131a, 141a) that have a protrusion height of 0.2-0.8 mm; and comprises the plurality of engagement elements (121a, 131a, 141a) that each independently protrude in the column direction of each engagement element column (121, 131, 141). A cushion material (10) is covered by a covering material (20) via the surface fastener (100). The resistance of the surface fastener (100) alone, as measured by a handle-o-meter conforming to JIS L 1096 E is 80-150 g and is higher than conventional fiber surface fasteners. T'he surface fastener exhibits similar load-deflection characteristics, when a pressure plate having a diameter of 30 mm applies pressure to an overlapping section of the surface fastener (100) and the cushion material (10) when same are stacked, to when the cushion material (10) alone is similarly measured.
A seat slide device includes lower rails and upper rails both formed substantially symmetrical bilaterally across a center in a width direction, and lock mechanisms on both sides of the upper rails to be engaged with the lower rails to lock them. An entire structure combining the lower rails, the upper rails and the lock mechanisms is substantially symmetrical forward, backward, and bilaterally, and a force applied to the lower rails and the upper rails can be absorbed substantially evenly forward, backward, and left and right. Since the lock mechanisms have an elastic lock member in a substantially center part in a longitudinal direction, the lower rails and the upper rails are elastically deformable for reduction of a biased load at a time of locking, improvement in vibration absorption characteristic, and the like, and a plate thickness of each material can be made thinner than conventional for weight reduction.

A novel technique for analyzing a biological state is provided. A body trunk biological signal (aortic pulse wave) extracted from the back of a body trunk is differentiated twice. By using a resultant second derivative waveform, a waveform component of a maximum amplitude of a low frequency appearing as a result of switch of an amplitude from attenuation to amplification in transition from a contracting phase to a diastolic phase of a ventricle is specified in each period of the second derivative waveform. Inflection points are specified that appear before and after the maximum amplitude waveform component. A biological state is analyzed using information about each of the inflection points. The two inflection points obtained from a reference form of the second derivative waveform of the aortic pulse wave substantially agree in time phase with first heart sound and second heart sound (or an R wave and a T wave in an electrocardiogram) indicating the dynamic state of a cardiovascular system. This enables analysis of a biological state.
To specify and detect a change in a biological state based on a disruption in a biological rhythm. The present invention has a configuration whereby it is determined on the basis of a frequency-gradient time-series waveform, and preferably a frequency-gradient time-series waveform obtained using a zero crossing point, whether or not a function adjustment signal that has a frequency below the changeover frequency of a cardiovascular fluctuation characteristic continues at least for a predetermined time. A disruption in the circadian clock, i.e., the biological rhythm, is clearly reflected in a long-period frequency component (function adjustment signal). In particular, the disruption has a strong effect on a frequency-gradient time-series waveform obtained using a zero crossing point. The disruption is therefore suitable for detecting a specific biological phenomenon emergence period brought about by a disruption in the biological rhythm such as jet lag.

ACOUSTIC AND VIBRATION INFORMATION ACCUMULATION MECHANISM, ACOUSTIC AND VIBRATION SENSING SYSTEM, AND COMPUTER PROGRAM
The present invention can more accurately detect bioacoustic signals and biological signals. An acoustic and vibration information accumulation mechanism (10) is configured to have a first layer (11), a second layer (12) and a third layer (13). A natural oscillator (122) having a prescribed natural oscillation frequency is arranged in the second layer (12). When acoustic and vibration information from the trunk and back is input, the natural oscillator (122) vibrates at the natural oscillation frequency, and said vibration as well as the acoustic and vibration information from the trunk and back are combined and emphasized. The combined resonance carrier (RC) contains the emphasized acoustic and vibration information from the trunk and back and can be captured as a clear signal. If a biological signal having a number of Hz equal to or below an aortic pulse wave (APW) or a pulse is obtained from the resonance carrier, the gain of said biological signal is increased, and the biological signal can be more accurately extracted.
The present invention enables the output sound of a speaker unit to be outputted as a surface sound source in a limited space. A three-dimensional cubic knitted fabric (43) is provided, with tension applied thereto in the surface direction, at a position where speaker units (31, 32) almost face each other. Because the tension is applied, a pair of ground knitted fabrics constituting the three-dimensional cubic knitted fabric (43) and a connecting strand reciprocating between the ground knitted fabrics vibrate due to the elastic action thereof. In particular, string vibration occurs in the connecting strand. The output sounds of the speaker units (31, 32) are propagated, by this vibration, in the surface direction of the three-dimensional cubic knitted fabric, so that the three-dimensional cubic knitted fabric propagates and radiates a sound wave of the surface sound source.

The present invention reduces neck injuries when a structure having a lifting mechanism section only on one side is adopted. While a lifting drive section (160) is provided on one side frame (11) side, a coupling drive rod (170) is connected to the rotation center of a drive gear (160d), a driven link (171) is provided on the other side frame (11) side, and the driven link (171) is connected to the coupling drive rod (170). Although the driving force at the lifting drive section (160) acts on the one side frame (11) side where the drive gear (160d) is provided, lifting takes place also at the other side frame (11) side as the driven link (171) rotates in conjunction with the drive gear (160d) via the coupling drive rod (170). Because the virtual quadrangle formed by connecting the respective contact points of the driven link (171), side connectors (153, 153), the coupling drive rod (170), and the drive gear (160d) is never deformed, external input is dispersed.

In the present invention, a second member is caused to rotate with respect to a first member in a smoother manner than has been conventional. The present invention has a worm (50) and a driving side worm wheel (40) and following side worm wheel (60) that are disposed sandwiching the worm (50). Of the worm (50), both ends in the axial direction are supported by a bearing, and in the direction approximately perpendicular to the axial center of the worm (50), the teeth of the driving side worm wheel (40) and following side worm wheel (60) make contact at both sides in the direction approximately perpendicular to the axial center with backlash, and are thereby supported. When the second member is rotated relative to the first member, the worm (50) rotates relative to the driving side worm wheel (40), the following side worm wheel (60) rotates by means of the rotary force of the worm (50), and the rotary force of the following side worm wheel (60) is regenerated by the worm (50). As a result, whirling vibration of the worm (50) is suppressed, and relative rotation occurs smoothly.

SEAT CUSHION POSITIONING MECHANISM AND VEHICULAR SEAT
Provided is a seat which allows not only a front-rear position and a vertical position but also a seating surface angle to be adjusted in an interlocked manner through a single operation, enables a hip position to be also set low in spite of the presence of an interlocking mechanism part, and is suitable as a seat for a sports car. When a cushion frame is slid either forward or rearward, the seating surface height of a seat cushion is raised or lowered in an interlocked manner with the sliding, and the seating surface angle also changes such that the seating surface angle at the foremost and uppermost position of the seat cushion becomes smaller than the seating surface angle at the rearmost and lowermost position. In other words, when the single adjustment operation of slide-adjusting in the front-rear direction is performed, the seating surface height and the seating surface angle are adjusted in an interlocked manner with the sliding.

Provided is a power seat slide device capable of switching to not only electric but also manual operation, and preventing half-lock in spite of a manually operable structure. For forward/backward movement, a rack (21) fitted to a lower rail (11) and a pinion (22) in threaded engagement with the rack are used, and driving force from a motor (51) is transmitted to the pinion (22). This configuration enables use in electric mode. Meanwhile, no slide screw is used, so that when the motor (51) is not energized, an output shaft of the motor (51) can be rotated by rotating the pinion, thus enabling manual adjustment.

A base net for a back is formed from a three-dimensional stereoscopic knit, and has a configuration in which seams for bringing a pair of ground knitted fabrics thereof to close to each other in a thickness direction are partially provided, predetermined preliminary compression is applied in the thickness direction by the seams, and thereby residual stress is generated in a surface direction (stretching direction). Therefore, stiffness is partially increased by partial improvement in residual stress, and consequently a human body with extreme roughness is supported by nearly uniform pressure. Thus, in spite of a simple configuration in which the seams are provided in desired regions, posture supportiveness and body pressure dispersiveness can be improved. Further, by arbitrarily adjusting the formation positions of the seams, the pressure distribution is adjusted, thereby making it possible to easily control the vibration mode to desired setting, and easily improve vibration absorbency.
Provided is a seat suspension having a compact configuration while being able to cope with an input vibration not only in the vertical direction but in the direction of six axes. Three sets of pantograph links (11) are adopted between a seat-side and a vehicle body floor-side. As a result, control in six axis directions is possible and greater simplicity is possible compared to conventional structures. In addition to an active control mechanism (10) using the pantograph links (11), the present invention has a compression coil spring (21) and a magnetic spring (22) as a first and second elastic member. In other words, highly efficient vibration removal is performed due to passive vibration removal by means of the elastic members while the seat side is controlled in the opposite phase with respect to the vehicle body floor side by means of the active control mechanism (10) with respect to the direction of input of vibrations.
A predetermined component such as a recliner is attached to a long member in advance, and thereafter by bending the long member, a pair of side frames and an upper frame are integrally formed. Therefore, the recliner can be attached to the long member not bent yet and thus in a substantially flat state, and in addition, the pair of side frames and the upper frame can be integrally formed, which does not require labor and contributes to a reduction in manufacturing cost. Moreover, by adjusting a position where the bending is performed, it is possible to manufacture seat frame structures different in dimension even if the long members not bent yet have the same length, and from this viewpoint as well, it is possible to reduce labor and manufacturing cost.

The present invention improves the absorption characteristics of low-cycle vibrations resulting from lateral swaying. A seat support member (20) that supports a seat is, with a lateral sway absorption mechanism (30) therebetween for absorbing lateral swaying, provided to brackets (13-16) that are vehicle-body-side attachment members attached to the vehicle body side. Consequently, it is possible for lateral swaying (low-cycle vibrations) arising as a result of phase deviations or the like in the hydraulic suspension of the vehicle to be absorbed by the lateral sway absorption mechanism (30), lateral deviation of the bodies of passengers is suppressed, and thus it is possible to increase the stability of the seated posture and furthermore to suppress the occurrence of motion sickness.
Provided are a driving assistance device and a computer program that induce wakefulness by applying a stimulus at a predetermined timing prior to the onset of intense drowsiness like that which occurs during the phenomenon of impending sleep. In addition to applying a stimulus as in the prior art at a timing that corresponds to a warning that is issued when each of various biological states that appear concomitantly with a decrease in wakefulness is at a warning level, for example, a timing at which the phenomenon of impending sleep is detected while wakefulness is decreasing and drowsiness is increasing, the present invention applies a stimulus using a timing at which symptoms related to a decrease in wakefulness are detected prior to reaching the phenomenon of impending sleep, for example, when an indicator that is obtained by analysis while estimating that a driver has not yet reached the phenomenon of impending sleep indicates a period of increase with respect to the degree of fatigue or a period of continuation of the same biological state.
Provided is a technique for more accurately assessing the state of a living body. Using a predetermined central-nervous-system index value calculated from central-nervous-system living-body signal information and a predetermined peripheral-system index value calculated from peripheral-system living-body signal information, the present invention estimates the state of the living body from the positional relationship between coordinate points on a coordinate system in which the predetermined central-nervous-system index value and the predetermined peripheral-system index value are plotted on coordinate axes. When the state of a person is to be estimated, by adopting a configuration in which both indexes are used rather than one or the other and the indexes are determined on a single coordinate system, as in the present invention, fluctuations in each index relative to variations in the state of the person are emphasized, and the state of the person can be more accurately estimated.
Provided is a seat suitable for a sports automobile having a low hip point. An energy absorption structure (100) provided to a cushion frame (10) is configured from an approximately square frame body provided with: a front beam (112) and rear beam (113); and stringers (110, 111) bridging therebetween and provided separately from side frames (11, 12). The structure is such that a belt anchor attachment member (117, 118) is provided to the stringers (110, 111) between the position of joining of the rear beam (113) and the position of joining to the vicinity of the rear of the upper rails (601, 611) of sliders (600, 610). When at least a predetermined shock force is applied, the stringers deform, absorbing the shock force, and a truss is formed after the deformation, by means of which it is possible to withstand further shock force that continues to be applied.

Provided is a seat such that it is possible to adjust the seat height by means of a simple configuration. A planar support member (150) is provided to the rear surface side of the cushion member for a seat cushion section, and by means of adjusting the magnitude of tension of the planar support member (150) by means of a reeling-in mechanism (160), the perimeter of the planar support member (150) between a front beam (112) and a rear beam (113) is altered, by which means it is possible to adjust the seat height of a seat occupant. It is possible to alter the seat height merely by adjusting the magnitude of the perimeter of the planar support member (150) without a structure for raising/lowering the cushion frame itself, and so the structure is simple and it is possible to suppress the hip point to a low point. Consequently, the present invention is particularly suited for being used in the seat of a sports automobile for which a low hip point is called for.

In order to inspect the quality of a drive mechanism for a vehicle seat more accurately without detecting the operational sound of the drive mechanism and thus distinguish between defective and non-defective products more accurately, a vibration sensor (2) is attached to a predetermined measurement point of a power unit for an electric power seat, and the presence/absence of abnormal sounds is determined by analyzing the vibrational waveform of the vibration sensor (2). Preferably, the presence/absence of abnormal sounds is detected by analyzing the frequency of the vibrational waveform, which is the detected signal, and determining the presence/absence of the superposition of irregular vibrations. Thus, in a technique for inspecting the quality of a drive mechanism, such as a power unit, for an electric power seat by employing the presence/absence of abnormal sounds, determination can be made more accurately and easily compared to conventional art even without a soundproofing environment.
Provided is a technique for grasping the biological state of a driver more accurately. The present invention comprises a means (621) for detecting phenomena that herald the onset of sleep, a means (622) for detecting phenomena that indicate the imminence of sleep, a means (623) for detecting subjective sleepiness and a low-consciousness driving state, and a means (624) for determining the level of homeostatic function, wherein said means function in parallel. Thus, each of said means can determine/detect: phenomena that herald the onset of sleep and phenomena that indicate the imminence of sleep; periods in which the driver resists subjective weak sleepiness (mild sleepiness) or strong sleepiness; or instances in which a low-consciousness driving state caused by a drop in consciousness level occurs momentarily or continues for a longer period. Thus, the driver's biological state can be determined more accurately compared to conventional art.
The present invention aims to reduce the thickness and weight of a seatback portion using a simple configuration. A seat cushion pad (110) has a main pad portion (111, 112) and a peripheral pad portion (113), a rear edge of the main pad portion (111, 112) being arranged in a cushion frame (100) so as to be pressed upward elastically with respect to the peripheral pad portion (113). In other words, the main pad portion (111, 112) on which a person sits is pressed upward elastically without the provision of a metal spring or the like. Thus, even if the main pad portion (111, 112) is made of a thinner material (urethane, etc.) than conventionally employed, it is possible to provide desired characteristics such as a sensation of the seat compressing when sitting thereon, vibration absorption, shock absorption, and the like; therefore, it is possible for the present invention to contribute to reducing the weight of a seatback portion using a simple configuration.

Provided is a seat sliding device suitable for weight reduction. The seat sliding device (40) has a configuration in which lower rails (41) and upper rails (42) are formed in left-to-right substantial symmetry on either side of a widthwise center, and lock mechanisms (43) are provided to both upper rails (42) and can be engaged with and locked to the lower rails (41). The entire structure combining the lower rails (41), the upper rails (42), and the lock mechanisms (43) is substantially symmetrical forward and backward as well as left to right, and the force applied to the lower rails (41) and the upper rails (42) can be absorbed substantially equally forward and backward as well as left to right. Because the lock mechanisms (43) have an elastic locking member (430) in the longitudinal substantial center, the lower rails (41) and the upper rails (42) can elastically deform about the longitudinal substantial center as a fulcrum, eccentric loads during locking can be reduced, vibration absorption characteristics can be improved, the plate thickness of the materials can be reduced below that of conventional products, and weight can be reduced.

Provided is a vehicle seat suitable for weight reduction. Left and right side frames (11) constituting a cushion frame unit (10) are configured from plate-shaped frames (111, 112) that are long in the forward-backward direction and that are formed from a metal material having a predetermined thickness or less, a plurality of beams (121-125) span between the side frames (11), and one or both of the side frames (11) are supported on a seat sliding device (40) via truss-shaped support parts. In other words, the side frames (11), being disposed in a direction substantially orthogonal to the plurality of beams (121-125), fulfill the role of stringers, and as a result, the forward-backward rigidity of the side frames (11) in particular is a high rigidity of at least a predetermined value even if the side frames are made of a thin material, and the side frames can be reduced in weight.

PHYSIOLOGICAL STATE-ANALYZING DEVICE AND COMPUTER PROGRAM
Provided is a novel technology for analyzing physiological state. The second derivative of a trunk biosignal (aortic pulse wave) from the dorsal trunk is obtained. Using the waveform of said second derivative, a low frequency maximum amplitude waveform component that appears when the amplitude switches from decrease to increase during ventricular systole to diastole is specified for each cycle. Inflection points positioned on either side, before and after said maximum amplitude waveform component are specified. The physiological state is analyzed using information on each inflection point. The physiological state can be analyzed because the time phases of the two inflection points obtained from the reference shape of the second derivative waveform of the aortic pulse wave substantially coincide with the first heart sound and the second heart sound (or are equivalent to the R wave and T wave in an electrocardiogram) that represent cardiovascular system dynamics.
A device to detect a state of a human being is provided. The device determines a time-series waveform of a frequency from a time-series waveform of a biological signal acquired from an upper body of a human being, and determines time-series waveforms of a frequency slope and frequency variation to analyze these frequencies. Upon analyzing the frequencies, it determines power spectrums of frequencies corresponding to a preset functional adjustment signal, fatigue reception signal, and activity adjustment signal, and then determines a state of the human being from a time-series change in each power spectrum. Dominant degrees of the functional adjustment signal and activity adjustment signal are compared as distribution rates thereof, in addition to a degree of progress of fatigue, to determine a state of the human being, for example a relaxed state, fatigued state, prominent state of sympathetic nervous, prominent state of parasympathetic nervous.
Seat frame structures having different dimensions can be formed from the same member enabling a reduction in labor and manufacturing costs and a reduction in the types of members to be prepared according to the dimensions. A certain component such as a recliner (170) is previously attached to an elongated member (1000) and then a bending step is conducted to integrally form a pair of side frames (110, 120) and an upper frame (130) in the present invention. Therefore, attachment work of the recliner (170) contributes to a reduction in manufacturing cost without incurring labor since the attachment work can be implemented while the elongated member (1000) is substantially flat before conducting the bending step and the pair of side frames (110, 120) and the upper frame (130) can be formed integrally. Moreover, by adjusting the position for conducting the bending step, seat frame structures with different dimensions can be manufactured even if the length of the elongated member is the same before conducting the bending step, thus enabling a reduction in labor and manufacturing cost.
In order to improve posture supportiveness, body pressure dispersiveness, energy absorbency, and the like, a base net (170) for a back is formed from a three-dimensional stereoscopic knit, and has a configuration in which seams (171a-171d) for bringing a pair of ground knitted fabrics thereof to close to each other in a thickness direction are partially provided, predetermined preliminary compression is applied in the thickness direction by the seams, and thereby residual stress is generated in a surface direction (stretching direction). Therefore, stiffness is partially increased by partial improvement in residual stress, and consequently a human body with extreme roughness is supported by nearly uniform pressure. Thus, in spite of a simple configuration in which the seams (171a-171d) are provided in desired regions, posture supportiveness and body pressure dispersiveness can be improved. Further, by arbitrarily adjusting the formation positions of the seams (171a-171d), the pressure distribution is adjusted, thereby making it possible to easily control the vibration mode to desired setting, and easily improve vibration absorbency.

BIOLOGICAL STATUS ESTIMATION DEVICE AND COMPUTER PROGRAM
Provided is a technique for more accurately ascertaining a person's status. In particular, the present invention makes it possible to accurately ascertain the detection of alcohol or the like. A fluctuation waveform of an ultra-low-frequency band is found from a biosignal collected from a biosignal measuring means, the fluctuation waveform is plotted as coordinate points on a four-quadrant coordinate system on the basis of a predetermined standard, and biological status is estimated on the basis of temporal change in the coordinate points. According to the method of the present invention for plotting a fluctuation waveform as coordinate points on a four-quadrant coordinate system on the basis of the predetermined standard, change in the fluctuation waveform of the ultra-low-frequency band can be expanded or highlighted and thus perceived, and therefore the present invention is adapted for more accurately perceiving change in a person's status.
In order to hold an upper frame capable of oscillating along the motion trajectory of a quadric crank chain that takes an inclined posture and an approximately horizontal posture in the approximately horizontal posture by a simple operation when necessary, an upper frame (20) capable of oscillating along the motion trajectory of a quadric crank chain between an inclined posture and an approximately horizontal posture is forcibly displaced to the approximately horizontal posture and held. A front link mechanism control means (100) applies external force for pushing down an operation member (120) to thereby control a front link mechanism (30) such that the front side of the upper frame (20) is displaced backward while being lowered. The direction of the displacement for bringing the upper frame (20) into the approximately horizontal posture and the direction of an operation for locking the front link mechanism (30) or a back link mechanism (40) by the operation of the operation member become approximately the same direction as each other, and consequently two movements, a displacement movement to the approximately horizontal posture and a lock movement, can be performed only by operating the operation member in a predetermined direction.

Provided is a technique for more accurately ascertaining a person's status. A three-layered structure is provided with a sensing mechanism section (230) disposed between a base cushion member (220) and a back-supporting cushion member (201) provided as a tension structure stretched on a back support section of a human body support mechanism, the base cushion member (220) and the back-supporting cushion member (201) being integrated together by a pouch member (210). A pelvic/lumbar support member (240) for urging a pelvic/lumbar support region of the back-supporting cushion member (201) is provided below the sensing mechanism section (230). The sensing mechanism section (230) is disposed between the base cushion member (220) and the back-supporting cushion member (201), and the cushion members therefore undergo tension in the surface direction. The back-supporting cushion member is provided so as to be stretched on the back support section of the human body support mechanism, whereby the sensing mechanism section (230) disposed on the backside of the back-supporting cushion member (201) is able to detect biological signals with high sensitivity.
A mechanical amplification device includes a three-dimensional knitted material and foam bodies and laminated in the periphery of the three-dimensional knitted material. A mechanical amplification device provided with a film is disposed between the three-dimensional knitted material and the foam bodies and is provided, and a vibration sensor is attached to this mechanical amplification device. Micro vibration on the body surface caused by a human biological signal is propagated to the foam bodies, the film, and the three-dimensional knitted material, and membrane vibration is generated in the foam bodies and the film, while string vibration of a fiber is generated in the three-dimensional knitted material. As a result, the biological signal such as heart rate, respiration, atrial and aortic vibrations and the like can be accurately transmitted.
A technology to grasp a state of a human being more accurately is provided. The technology is provided with means for acquiring a time-series waveform of a frequency from a time-series waveform of a biological signal sampled from the upper body of a human being and for further acquiring a time-series waveform of frequency slope and a time-series waveform of frequency fluctuation and for applying frequency analysis to them. In the frequency analysis, a power spectrum of each frequency corresponding to a functional adjustment signal, a fatigue reception signal, and an activity adjustment signal, respectively, determined in advance is acquired. Then, a state of a human being is determined from a time-series change of each power spectrum. The fatigue reception signal indicates a degree of progress of fatigue in a usual active state and thus, by comparing it with degrees of predominance of the functional adjustment signal and the activity adjustment signal as their distribution rates, a state of a human being (relaxed state, fatigued state, state in which sympathetic nerve is predominant, a state in which parasympathetic nerve is predominant and the like) can be determined more accurately.

Provided is an armrest that can be produced at a low cost and with a lightweight structure, and is able to prevent pinching of clothes or fingers by means of a simple structure. A core plate (20) and a cover member (30) are integrally formed, the core plate (20) is, excepting a portion of the surface thereof, covered by the cover member (30), and the base (21) of the core plate (20) is disposed face-to-face with a base member (10) provided with stoppers (10b, 10c) that limit the range of pivoting of the core plate (20). The contact between the stoppers (10b, 10c) and the core plate (20) in both a normal-use position and a flipped-up position of the armrest (1) is within the range that is covered by the cover member (30), and so clothing and fingers are not pinched between the two.

It is possible to elastically support the planar support member (150) and a base net (300) by means of the elasticity in the planar direction of the hook-and-loop fastener (170) and the elasticity of the anterior elastic support member (160), and so a torsion bar or arm is not necessary and it is possible to achieve a simpler structure and greater lightness of weight.
