ABSTRACT:
A motor-vehicle seat is carried on at least one slide displaceable along a guide rail having an upper edge formed with a plurality of upwardly open notches. Inside this guide rail is an adjustment member which is vertically displaceable so as frictionally to engage the guide rail and arrest the slide relative to the seat. Furthermore a safety member is provided which is also carried on the slide and which is displaceable toward and away from the notches formed in the upper edge of the guide rail. Respective springs urge the adjustment and safety members into the positions locking the slide and rail relative to each other. A common handle is actuatable to pull the adjustment member out of engagement with the rail and to pull the safety member also out of engagement with the notches of the rail. Thus in case of a collision even if the frictional engagement of the adjustment member with the rail is insufficient to lock the seat in position, the engagement of the safety member with the notches will suffice.
