Abstract: The seat comprises a cushion foldable about its front edge and two side-by-side backrests. The two backrests (1 and 2) are carried by a horizontal rod (16) connected by an articulated link (18) to a fixed support (20). One of the backrests (2) is connected in its lower part to a rotative element (28) rotatable about the pivot axis of the horizontal rod. The other backrest (1) is free to pivot about the rod so that it may be folded over alone onto the cushion of the seat by this pivoting while it is capable of being folded over with the other backrest (2) onto the floor by pivoting therewith about the pivot axis X--X of the rod carrying the backrests.

Abstract: The seat cushion and/or the backrest of the seat comprising an elastic layer (4) carried by a frame and provided with two lateral projecting wings (8) in which an inverted U-shaped driving rod (14) is connected to the upper part of one of the wings and is pivotally mounted relative to the frame (2). This rod is extended at one of its ends by a connecting lever bent around the frame element and connected to a control cable controlling its pivoting fixed to the door (38) of the vehicle. In this way, this door exerts a pull on the cable which causes the rod (14) to pivot and thereby turns the wing (8) outwardly and clears the access to the seat.

Abstract: A locking bolt (14) is slidably mounted in the external element (1) of the slide. It has side teeth (16) cooperating with holes in this external element and, at its end removed from these teeth, a hole (28) for receiving an actuating pin (32) which also passes through the internal element (2) of the slide. The cross-section of the pin (32) complements the hole of the bolt such that rotation of the pin about itself causes locking. The pin is movable axially and may be disengaged from the bolt so as to allow momentary relative axial displacement of the internal element and return into the previous position indicated by the bolt.

Abstract: A sitting-surface frame (10) and a backframe (1) are connected to one another, on each side of the seat, at two mutually spaced points, one comprising a tilting axle (34) and the other a folding-down axle (8).
