Abstract: The invention relates to a vehicle seat back comprising firstly a rigid frame (2) having first and second side uprights (41, 5) and top and bottom cross-members (42, 43) interconnecting the first and second side uprights (41, 5), and secondly a resilient supporting sheet (3) fixed to the rigid frame (2) and placed so as to come directly into contact with the back of a user. According to the invention, the supporting sheet (3) forms a bag that is fitted onto the rigid frame over its first side upright (41) so as to cover the top and bottom cross-members (42, 43) and the first side upright (41), with the second side edges (64, 74) of the front and rear faces of the resilient supporting sheet (3) being fixed to the second side upright (5).

Abstract: Modular seat layout system in an automobile vehicle, especially for the seats of the first and second rows Modular seat layout system in an automobile vehicle, including at least two seats (1, 2) located one behind the other. The front seat (1) is attached to the floor (4) of the vehicle by a first set of hinged items (14, 15) so that the seat pan (11) of the front seat can translate forwards to be housed, in a forward position, in the space (E) existing in front of the front seat when it is in normal utilization position and the backrest (12) extends more or less horizontally towards the rear from the seat pan, more or less at the location that the said seat pan occupies in normal utilization position. The rear seat (2) is attached to the floor (4) by a second set of hinged items (24, 25, 28) so that the said rear set can be folded and placed against the backrest (12) of the front seat.

Abstract: Modular seat layout system in an automobile vehicle, especially of the type including three rows of seats, including at least two seats (2, 3) located one behind the other. The rear seat (3) is attached to the floor (4) of the vehicle by a first set of hinged items (34, 37, 44) so that the seat pan (31) of the rear seat can translate forwards to be housed, in a forward position, in a space (5) provided for this purpose below the location which is occupied by the seat pan (21) of the front seat (2) in the normal utilisation position of the said front seat.

Abstract: The bucket seat comprising a seat part (10) with a cushion (11) carried by a framework (12) mounted on a subframe (14), a backrest (20) with a cushion (21) carried by a framework (22), and an articulation (30) connecting the subframe (14) of the seat part (10) to the framework (22) of the backrest (20) in order to allow the cushion (21) of the backrest (20) to be pivoted, is characterized in that the framework (12) of the seat part (10) cushion (11) is mounted on the subframe (14) by the interposition of a turntable (13) and in that the seat part and backrest cushions (11,21) each comprise a surface (110) which is conjugate with a complementary surface (210) which fit together at least partially on one another.Application in particular to vehicles known as coupes.

Abstract: The covering (20) for a seat, made from an outer envelope (21) and an inner padding (22) shaped into a central pad (221) bordered by two side wings (222), where the pad (221) and wings (222) are arranged so as to form a pan (200), the concavity of which is intended to receive an occupant, where the padding (22) takes the form of a unit (30) consisting of comprising two elements (31, 32) separated by a joining surface (300), and where that one (31) of these elements (31, 32) which is closes to the pan (200) is made from a material which has a softer consistency than that of the material of the other one (32) of these elements (31, 32), so that when the pan (200) of the padding receives an occupant, the force exerted on the covering (20) straight the pad (221) causes the wings (222) automatically to be brought closer to each other by pivoting about a hinge zone (3020), and vice versa.
