Abstract
An arresting device in a longitudinally adjustable guide rail assembly for motor vehicle seats includes a shaft rotatably supported in a stationary bearing plate and driven by a stationary electromotor; the driving pinion of the electromotor is in mesh with an intermediate gear which is supported for free rotation on the shaft; a coupling disk is supported for joint rotation on the shaft and for an axial displacement between the bearing plate and the face of an intermediate gear. The bearing plate portion opposite the coupling disk is provided with a ring of arresting teeth and also the facing side of the intermediate gear is provided with a corresponding toothing. Both sides of the coupling disk are serrated and normally are urged by a cup spring into engagement with the arresting teeth of the intermediate gear. In the case of a collision when the shaft is rotated by inertial forces acting on the seat, the inclined surfaces of the teeth on the intermediate gear displace axially the coupling disk and bring the same into engagement with the teeth of the arresting ring so that the reduction gears of the driving motor are bypassed and the seat is held in its adjusted position.
