Patent ID: 7594634

Claim:
A device for enabling a motor vehicle seat to slide, said device comprising: a runner comprising a stationary rail designed to be fastened to the structure of the vehicle and a moving rail mounted to slide relative to the stationary rail; a locking device mounted on the moving rail and having an active state in which the locking device holds the moving rail stationary relative to the stationary rail and an inactive state in which the locking device allows the moving rail to slide relative to the stationary rail; a control support mounted to pivot on the moving rail between an active position in which the control support constrains the locking device to be in the inactive state and a rest position in which the control support allows the locking device to return to the active state; a control rod mounted to pivot on the control support between an in-use position and a retracted position, the control rod pivoting in an actuation direction from the in-use position causing the control support to pivot towards the active position, and the control rod pivoting in a retraction direction opposite from the actuation direction allowing the control support to return to the rest position, and causing the control rod to move from the in-use position towards the retracted position; and a torsion spring having a first end coupled to the moving rail, a second end coupled to the control rod, and an intermediate portion coupled to the control support, said spring tending to bring the control rod into the in-use position and tending to bring the control support into the rest position.
