Abstract: A seat in which the backrest armature is composed of two uprights which, joined together by at least one crosspiece, are joined to the seat part armature by a fixed or articulated connection.

Abstract: The expanding and retracting ball- and broach-type lock comprises a striker plate (10), a catch bolt (20), a control device (30), an orientation device, a position detector, a safety device, a safety feature and, preferably, an ejector (80).The lock is mounted on a support (90) such as a seat subframe with a sole-plate (91) and a leg (92) which are articulated in order to rock relative to each other.Use for a removable of a "single-volume people-carrier type" vehicle seat.

Abstract: The multi-position seat is fitted with linkage rod (50) which comprise a connecting rod assembly (51), a scissor-type stay (52), preferably a biasing urging element (53), as well as limit stops (54) and a stop-piece (55), a cam (56) and also a cam follower (57). These linkage rod provide the automatic control of the relative displacements of the seat part and backrest cushions during changes in their relative positions.

Abstract: The seat structure comprises a latching device (60) which is partly carried by one of the brackets (12,22) and partly by the other of these brackets (12,22) for latching in two opposed directions the backrest (20) to the seat (10) when the backrest occupies at least one of two particular positions, namely a "normal" position and a "relaxing" position so as to absorb and/or transmit important forces to which the seat structure is subjected in the event of a shock having a large longitudinal component. The latching device is brought into action by a hand control (50) of a locking mechanism. The seat structure is particularly applicable to so-called "one volume" or "monospace" vehicles.

Abstract: A movable arm rest, the position of which is adjustable by a motor, and which can be used in particular between the two front seats of a motor vehicle.The arm rest comprises a movable component (1), the upper upholstered part (2) of which serves as a support for the user. By virtue of a motor which is fixed with respect to a support plate (5) disposed at the base of the movable component, the arm rest is displaced along inclined guide ramps which are fixed with respect to a fixed frame (4). The drive is provided by way of pinions (16) meshing with racks (47).
