Abstract: A motor vehicle seat comprises a seat proper and a seat back which is mounted to pivot between an in-use position and a folded-away position, a first latch holds the seat back in its in-use position, and at least one headrest is pivotally mounted on the seat back to pivot between an in-use position and a folded-away position in which the headrest is tilted forwards, a second latch for preventing the headrest from moving in its in-use position, and a coupling device adapted to displace the headrest into its folded-away position when the seat back is tilted forwards.

Abstract: A slide for adjusting the longitudinal position of a vehicle seat, comprising an upper shaped-section adapted to slide along a fixed lower shaped-section and carrying a bolt adapted to coact with a fixed rack. The bolt is controlled by a longitudinal rod housed in two transverse lugs, the front one being integral with the upper shaped section and forming a transverse pivoting axis X whereas the rear one is integral with the bolt, which is mounted so as to pivot about a longitudinal axis Y. A torsion spring ensures that the resilient return and the positioning of the parts.
