A retractor shaft is rotatably mounted in a loadbearing housing. A webbing clamping means consists of a clamping member mounted movably on the housing and a housing-fixed clamping face disposed opposite to and spaced from said member. The actuation of the clamping member is via an actuating nose on a ring which is provided with an internal toothing and which is rotatably mounted on a side plate of the housing. On one side of the retractor shaft two pawls are eccentrically and pivotally mounted in their center of gravity in such a manner that the engagement faces lie opposite the internal toothing of the ring. The pawls are driven by mass inertia forces against the force of a return spring into coupling engagement with the internal toothing of the ring. The longitudinal component of the arcuate movement of the actuating nose is transmitted directly via a pin and a slot to the clamping member.
