Abstract
A seat rail module with two rails for longitudinal adjustment of a vehicle seat comprises a drive member, at least one deformation member coupled to an associated rail for longitudinal adjustment, at least one fastening member for fastening the drive member, and an actuator for locking and unlocking the at least one fastening member. The deformation member is deformed upon displacement of the vehicle seat in a main direction of travel to dissipate crash energy and decelerate the vehicle seat. In a locked position of the fastening member, the drive member is directly secured to a rail by the fastening member. The fastening member is mechanically unlocked upon displacement of the vehicle seat beyond a predetermined limit setting, so that the drive member is coupled to an associated rail via the deformation member, to enable a displacement of an upper rail relative to a lower rail for dissipating impact energy.
