Abstract: A fastener device (10) for fastening a load to a rail (4) that is provided with a slideway (4?) defined by a bottom wall (5), two side walls (6), and a top wall (7) including a succession of wide slots (8) and of narrow slots (9), said fastener device (10) comprising a base (20) and two shoes (30) suitable for being inserted in said wide slots (8) and for co-operating with the top wall (7) in a narrow slot (9) by shape interference. The device further comprises first and second slides (31, 32), each including one of said two shoes (30), spacer means (40) for spacing apart said first and second slides (31, 32), detector means (50) for detecting a rail (4?), approach means (60) for causing said first and second slides (31, 32) to approach each other, and blocking means (70) for longitudinally blocking said base (20).

Abstract: This seat comprises a backrest armature (28) connected to a seat-part armature (22) by means (34) of articulation about an axis (X) substantially transverse to the seat. The backrest armature (28) carries a substantially transverse rod (56) for attaching a cover covering the backrest padding. This attachment rod, which runs close to the means (34) of articulation, has end extensions (60) forming protections intended to prevent a passenger sitting behind the seat from impacting against the means (34) of articulation. As a preference, each protective extension comprises a bow (60) curved around the axis (X) of articulation substantially parallel to a plane perpendicular to this axis.

Abstract: The U-shaped framework element for a seat made from a deformed hollow tube makes it possible to form a component which comprises two practically parallel branches (10) and a transverse bridge (20) which joins them together with the aid of elbows (30). In cross section, these branches (10) and elbows (30) have a channel configuration with one dished face (11) and a flat opposite face (12), and in cross section, this bridge (20) has a polygon-shaped configuration with straight sides (21) and rounded vertices (22).Use to land motor vehicles whose padding is clipped on.
