Abstract

A device for selectively monitoring and reducing a backward displacement of a vehicle seat in the event of an accident, having at least one stop element (4) which arranged on a pair (1) of seat rails and has a stop face (5) which is inclined with respect to a longitudinal axis of the pair (1) of seat rails, and having at least one stop body (6) which is arranged on the vehicle seat, having a contact face (8) which is arranged in a normal position at a distance from the stop face. In order to make available a device which efficiently reduces a backward displacement movement of a motor vehicle seat in a simple way in the event of an accident of the motor vehicle, there is provision that the stop element (4) and the stop body (6) are embodied and arranged with respect to one another in the mounted state in such a way that in a crash position which occurs in a tail-end impact with a motor vehicle having the vehicle seat, the stop face (5) of the stop element (4) and the contact face (8) of the stop body (6) enter into contact and as a result the backward displacement of the vehicle seat which is caused by the accident is reduced.
