Device for energy absorption in particular for an automotive vehicle seat upon impact, said device comprising a first element substantially in the form of a plate with a hole and a second element inserted in the hole, said first element comprising a series of cutouts that are successive along a deformation direction and define a series of yokes between each other extending along a direction of elongation transversal to the direction of deformation, said yokes having each a length along the direction of elongation, said length increases strictly from one yoke to the next according to the distance of the yokes in relation to the second element and the yokes having an overall concavity turned towards the second element.

An armature assembly is provided for a vehicle seat. The assembly includes an armature having a central web extending in a plane substantially orthogonal to the transverse direction of the vehicle seat. A first flange extends from a first edge of the central web that is situated towards the outside of the seat, the first flange extending in a first direction toward an opposite side member. A second flange extends from a second edge of the central web that is situated towards the inside of the seat, the second flange being directed toward a second direction, opposite the first.

The headrest (1) comprises a translation guidance assembly (10) guided along a spindle (2) attached to the seat back and an articulation assembly (20) that is mounted swivelling on the guidance assembly, around an axis (7). A locking member (30) swivels on the guidance assembly (10) around an axis (8) that is parallel to the axis (7), between a locked and an unlocked position. The locking member comprises a pad (31) shaped to press on the spindle (2) in the locked position, and a head (32) that is shaped to lock on a curved section (23), attached to the articulation assembly. In this locked position, that the locking member takes under the effect of inertia after a collision, the headrest can neither pivot backwards nor slide downwards. Application of the headrest is directed to automotive vehicle seats.

A vehicle seat includes a seat part which is formed by a cushion secured to a first armature itself supported by a second armature on which the backrest is mounted, it being possible for the first armature to be moved back and forth with respect to the second armature. The first armature includes a rear part which is suspended from the second-armature by at least one rear connecting piece, and the first armature further includes a front part which is linked to the second armature by a front mechanism compatible with the rocking motion of the rear part of the first armature. When a user is seated in the seat, the first armature is urged backward by the weight of the user.

The automobile vehicle seat features a seat back hinged on the seat pan and means for blocking the seat back with respect to the seat pan in the event of forward impact. It features a height adjustment mechanism. The seat back blocking means comprise a cam pivot-mounted on the shaft, and a weight joined to the cam, with the cam arranged so upon impact, it is caused to pivot by the inertia of the weight, it engages with a lower edge of the seat back frame, such that pivoting of the seat back is prevented by bracing of the cam against the said lower edge and such that this produces a high radial force (F) on the height adjustment shaft, thereby limiting the possibilities of rotation of the said height adjustment shaft.

A vehicle seat has a cushion supported by a suspension web extending within a rigid frame. The suspension web is elastically deformable in traction in a longitudinal direction and it is fixed to the frame at one of its longitudinal ends, while its other longitudinal end is fixed to a portion of a raising mechanism enabling the height of the seat proper to be adjusted by the user acting directly on the seat proper. The suspension web exerts traction on the raising mechanism that urges the seat proper upwards.

The seat comprises several swivelling pins parallel with each other and about which the seat nose pivots successively from a given position to a following one, while the seat nose has the general shape of a polygon, the successive sides of which have increasing lengths. The position of said pins in relation to said sides is such that the seat nose surface facing upwards in each one of said positions is substantially in prolongation of the top surface of the cushion and in close proximity to it.

Vehicle seat structure comprising first and second metal sections that extend substantially parallel to one and the same plane in two different directions and that form a junction where the first and second sections are welded together. The first section comprises a cut-out into which the second section is fitted.
