Side member (23) for a chassis (27) provided with a wheel (26) which side member (23) comprises an upper flange (32) and a lower flange (33). Both of the flanges (32, 33) of the side member (23) have a continuous extension along the whole of the side member's (23) entire length. The upper or lower flange (32, 33) exhibits two oppositely directed curved portions (38, 39) that are both located in front of or behind said wheel (26) so that the curved flange's (32, 33) perpendicular distance to the non-curved flange (32) at one end of the chassis (27) is greater than the corresponding perpendicular distance to the non-curved flange (32) at the other end of the chassis (27). The non-curved flange (32) and the curved flange (33) are connected to one another via at least one connecting member (40, 51, 52). The side member (23) is provided with a centre flange (34) which is located between said upper flange (32) and said lower flange (33) and which extends from one end of said upper and lower flange (32, 33) to a region located between said two curved portions (38, 39).

B62D 21/09 - Means for mounting load bearing surfaces
A sandwich element (10) including a first restriction layer (21) and a second restriction layer (22) and a distance core (23) of a light weight material, preferably of a foam material, between said restriction layers, whereby the second restriction layer (22) includes stiffening elements (11) arranged in parallel with each other and individually or together with a corresponding abutting stiffening element (11) form a closed hollow profile (24). Furthermore the invention refers to a load floor shaped as such a sandwich element and also that such a load floor is a part of a cargo vehicle.

METHOD OF COLD FORMING A PIECE OF SHEET METAL BY BENDING OR PRESS MOULDING
A method of cold forming a piece of sheet metal (1) by bending or press moulding, in which method: - the piece of sheet metal is bent over a bevelled edge (12, 13) of a tool (10) so that the piece of sheet metal in the bending area (B1, B2) is subjected to compressive stress, on the inner side and tensile stress on the outer side of the neutral layer. A gap is left between the sheet metal and an edge surface (14, 15) of the bevelled edge. - compressive force is then exerted on the piece of sheet metal outside the bending area, which is compressed transversally to the longitudinal direction of the bend, whereupon compressive force is exerted on the outer side of the bending area so that the bending area is subjected to tensile stress on the inner side and compressive stress on the outer side of the neutral layer.
Platform body (1, 80) comprising a bottom (21) to which two opposite sides (31, 32, 41, 42, 63, 83, 84) are connected that either consist of long sides or of short sides as well as at least one additional side for the formation of a cargo volume (LV), said bottom having a bottom surface of a surface length between the opposite sides of the platform body (1, 80) that is larger than the spacing between said opposite sides, at least one part of said bottom being curved inward toward the cargo volume (LV), wherein at least one tie means (22) is mounted with one end thereof connected to one of the opposite sides of the platform body (1, 80) and with the other end thereof connected to the other opposite side of the platform body (1, 80) in order to eliminate deflection of said sides when the bottom of the platform (1, 80) is loaded by goods.
Platform body (1, 80) comprising a bottom (21 ) to which two opposite sides (31, 32, 41, 42, 63, 83, 84) are connected that either consist of long sides or of short sides as well as at least one additional side for the formation of a cargo volume (LV), said bottom having a bottom surface of a surface length between the opposite sides of the platform body (1, 80) that is larger than the spacing between said opposite sides, at least one part of said bottom being curved inward toward the cargo volume (LV), wherein at least one tie means (22) is mounted with one end thereof connected to one of the opposite sides of the platform body (1, 80) and with the other end thereof connected to the other opposite side of the platform body (1, 80) in order to eliminate deflection of said sides when the bottom of the platform (1, 80) is loaded by goods.
Dumper body (1) comprising a front bottom part (2) and a rear bottom part (14), the front bottom part (2) and the rear bottom part (14) being connected to each other at a bottom angle less than 180°, the rear bottom part (14) ending in an opening (16) and accordingly leaning in relation to the front bottom part (2), as well as that a front end portion (21) in addition is connected to the front edge of the front bottom part (2) in order to limit the loading space of the dumper body in the forward direction, an intermediate part (19) being placed internally in the dumper body (1 ) between and on top of the front bottom part (2) and the rear bottom part (14) at a deviating bottom angle in relation to both the front bottom part (2) and the rear bottom part (14) in such a way that a hollow space (H2) is formed between the front bottom part (2), the rear bottom part (14) and the intermediate part (19).
