Abstract: A rear seat for a motor vehicle includes a squab, the front of which is articulated to the motor-vehicle body, and a backrest connected to the body. The backrest can adopt a vertical position of normal use, a first lowered position in which it bears on the squab. and a second lowered position in which it bears directly on the floor after the squab has been pivoted forwards. A double articulation which enables the backrest to be put into these positions includes two articulation pins connected rigidly to the backrest and an S-shaped body which is carried by the vehicle body and whose two sides define two guide tracks with arcuate profiles which are engaged by the two pins.

Abstract: A front seat (1) for a motor vehicle with only two side doors includes a frame and a device for connecting the frame to the floor (15) of the motor vehicle which enable the seat to be moved between a normal operative position and a forward inoperative position in which access to the rear seats of the motor vehicle is facilitated, the connection device comprising at least one pin-slot coupling (23, 25) operatively interposed between the seat frame and the floor (15) of the motor vehicle and also including guides (5) allowing the adjustment of the operative position of the seat longitudinally of the motor vehicle. The seat further includes an auxiliary support structure (7) which supports the seat frame. The guides are operatively interposed between the seat frame and the auxiliary support structure (7). The pin-slot coupling (23, 25) is operatively interposed between the auxiliary support structure (7) and the floor (15) of the motor vehicle.

Abstract: The structure of a motor vehicle seat is constituted by a plurality of modular sub-units which are put together and are each produced in various mutually interchangeable versions so as to enable efficient and economical production of various models of seat. Each vehicle seat includes a main frame having a longitudinal guide device and a backrest adjustment device, a squab frame having different adjustment features, a backrest frame having different adjustment features, a specific padding and a specific cover therefor.
