Abstract: A seat for a motor vehicle includes a seat and a backrest, the seat including inner and outer lateral supporting legs, the legs being placed on either side of the seat and being designed to be joined to the motor vehicle. The seat also has a beam for joining the seat to the inner and outer supporting legs. The beam extends laterally between the supporting legs and is joined to the seat and legs. The joining beam is arranged so as to transmit the energy of a side crash from the outer lateral supporting leg to the inner lateral supporting leg. The inner supporting leg has a structure arranged so as to deform and absorb at least a part of the energy from the side crash.

Abstract: A convertible car seat that can take on a variety of configurations. These include seat, shelf, document case and flat configurations. The convertible seat is made up of two surfaces, one of a seat and one of a backrest. These are supported by two frames which are symmetrical with respect to a horizontal frame. The frames are made of rigid elements. The elements are connected by joints at each end to create a unit of four axles which permit folding the rigid elements to various configurations.

Abstract: The invention relates to a seat for a motor vehicle comprising a seat (2) and a backrest (3), said seat comprising lateral supporting legs, inner (5) and outer (4) respectively, said legs being placed on either side of the seat (2) and being designed to be joined to the motor vehicle, said seat also comprising a beam (6) for joining the seat (2) to the inner (5) and outer (4) supporting legs, said beam extending laterally between the supporting legs (4, 5) and being joined to said seat and to said legs, the joining beam (6) being arranged such as to transmit the energy of a side crash from the outer lateral supporting leg (4) to the inner lateral supporting leg (5) and in that the inner supporting leg (5) has a structure arranged so as to deform and absorb at least a part of the energy from the side crash.

Abstract: The invention refers to a convertible car seat (1) that can take on various configurations such as seat, shelf, document case and flat, comprising: a seat (2) and a backrest (3); a support made up of two frames (6), the sides of which are made up of rigid elements (8, 9, 10, 11, 8?, 9?, 10?, 11?) connected to each other by means of joints (A12, A13, A14, A15) placed on each of their ends on an axle (12, 13, 14, 15) in such a way that the support can be folded in the manner of a foldable quadrilateral, in which at least one of the joints (A12, A13, A14, A15) is lockable, the seat (2) is mounted lockably connected to the third axle (14), arms (16) are placed on either side of the seat, the backrest (3) is mounted on one end (18) of the aforementioned arms (16) by means of at least one lockable joint (19). The invention also relates to a vehicle that includes at least one such seat and a method for transforming such a seat.
