Abrégé

An assembly (1) for tiltably joining seat and base of a chair, wherein the assembly (1) comprises a top member (2) for attachment to the seat, and a bottom member (3) for attachment to the base. The top member (2) is arranged tiltably relative to the bottom member (3) by means of at least two spacing means (4) interposed between the top and bottom members (2, 3). The spacing means (4) are configured to define at least one axis of relative rotation between the top and bottom members (2, 3). Further, the assembly (1) comprises a resilient elastic means (12) interposed between the top and bottom members (2, 3) and configured to be increasingly stressed when the members (2, 3) are increasingly tilted relative to each other away from a normal position.

Abrégé

A device for an adjustable piece of seating and reclining furniture with an adjustable angle between the seat and the back of the piece of furniture, wherein on each side of the piece of furniture there is located a fitting projecting upwards from its base, the seat being tiltable about a forward suspension point on the fitting, and the back being tiltable about a rear suspension point on the fitting, wherein the back upon tilting backwards causes the seat to tilt backwards in that a link is pivotally fastened to a rear part of the seat frame and pivotally fastened to a lower part of the back frame, the pivotal connection of the link to the back frame being located behind and below said rear suspension point. On an increase in the angle between the seat and the back, the angle that the neck rest of the piece of furniture forms with the back is reduced. When the piece of seating and reclining furniture is equipped with a foot/leg rest, an activator for this rest and an activator for changing said angle between the seat and the back are controllable by one single, common control lever or control handle.

Abrégé

A chair device (2), wherein the chair has a base (3), an upright, length-adjustable supporting column (5) which at the bottom is connected to the base, and a seat device (6) which is tiltably or non-tiltably connected to an upper region of the supporting column (5). A lower, elastically resilient coupling (12) forms a tiltable connection between the base (3) and a lower portion (5') of the supporting column (5). The lower coupling (12) is designed to permit tilting of the supporting column (5) relative to the base (3) in any one of 360° of tilting direction or only in one tilting direction.
