ABSTRACT:
In a self-locking belt roller, especially for motor vehicles, having a vehicle-sensitive and/or belt-sensitive control system for its locking element, which in the blocking case prevents further rotation of the belt winding shaft, and having a winding-up spring acting on the belt winding shaft, in certain operational conditions the blocking system of the belt roller should be permanently ready to operate. In this respect a device, becoming operative when the belt is completely unwound and becoming inoperative when the belt is wound up, is provided for fixing the control system in its position which brings about the blocking position of the locking element upon extraction of the belt, this device being actuated by the belt winding up and unwinding.
