The invention concerns an adjustable seat (10) for motor vehicle comprising a substantially horizontal seating element (14) of the rear part of which is articulated a back (16), a device for adjusting (21) the position of the seating element (14) of the seat (10) relative to the vehicle structure and means for locking and unlocking the adjusting device (21). The invention is characterized in that it comprises reinforcing means (56), separate from the adjusting device (21), which absorb at least part of the impact loads provoked by a longitudinal shock, in particular at the front of the vehicle so that, at the time of impact, the deformation of the adjusting device (21) is reduced, thereby reducing the tilting movement, in particular forward, of the adjustable seat (10) about a rocking axis with global transverse orientation.
An adjustable seat (10) for a motor vehicle, said seat being of the type provided with a substantially horizontal seating element (14), on the rear part of which there is mounted a back (16) via a joint, a device (21) for adjustment of the position of the seating element (14) of the seat (10) relative to the vehicle structure, and means for blocking and unblocking the adjusting device (21), characterized in that it is provided with reinforcing means (56) which are separate from the adjusting device (21) and which, during a longitudinal impact, especially at the front of the vehicle, absorb at least part of the collision forces caused by the impact, thus reducing the deformation of the adjusting device (21) and thus reducing the tilting movement, especially toward the front, of the adjustable seat (10) around a geometric tilt axis of generally transverse orientation.
An adjustable seat (10) according to the preceding claim, characterized in that the reinforcing means (56) are provided with at least one reinforcing leg (64), which is mounted to rotate via its first end (66) around a transverse pivoting axis (A6) in the seating element (14) of the seat (10), and which pivots around this transverse axis (A6) between an engaged reinforcing position, in which its second end (72) cooperates with the vehicle structure, and a retracted position designed to permit adjustment of the position of the seating element (14).
An adjustable seat (10) according to the preceding claim, characterized in that the second end (72) of the reinforcing leg (64) cooperates with a notched element (62) integral with the vehicle structure, in order to define the engaged position.
An adjustable seat (10) according to the preceding claim, characterized in that the control device (65) is provided with a bar (76) connected to the reinforcing leg (64) in a zone situated between the pivoting axis (A6) and the second end (72), and in that the displacement of the bar (76) permits pivoting of the reinforcing leg (64) around the pivoting axis (A6), between its engaged position and its retracted position.
An adjustable seat (10) according to the preceding claim, characterized in that, during unblocking of the adjusting device (21), the reinforcing leg (64) is in retracted position before the adjusting device (64) is unblocked.
An adjustable seat (10) according to any one of the preceding claims, characterized in that the device (21) for adjustment of the position of the seating element (14) of the seat (10) comprises two front couplers (22) and two rear couplers (24).
