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 rapid fastener is adapted to achieve a connection in the axial direction and in rotation of two elements and more particularly torque-transmitting shafts. It comprises at the end of one of the elements a socket (8) which is provided with at least one helical slot (14, 16) and on which is axially slidable a ring (18) defining at least one longitudinal slot which is laterally offset relative to the entrance (14) of the helical slot. The ring (18) is biased by a spring (24) toward the entrance of the socket (8). The second element has a stem (4) provided with a driving pin (6) which, in entering the helical slot, urges back the ring but is guided under the action of the spring (24) and the edges of the two slots toward the inner end of the helical slot and is then locked in this position without clearance.

Abstract: A device for effecting fine adjustment of the orientation of a steering wheel on a shaft (10), which are joined together by a fastener (30), has a sleeve (40) interposed between the end (11) of the shaft (10) and the hub (20) of the steering wheel. The sleeve and the shaft define between them an annular chamber (42) in which is housed a friction member (50) opposing their spontaneous relative rotation. The fine adjustment, limited to a value of about 9.degree., is made with the aid of an arrangement including a control mechanism, amplitude limiters, and stops. These stops ensure continuity of transmission of the torque exerted on the steering wheel to the shaft in the event of slackening of the fastener or failure of the amplitude limiters.
