Abstract: A self-locking belt retractor in particular for motor vehicles with a vehicle-sensitive and a webbing-sensitive control system for the blocking device of the belt retractor having an operatable toothed lock washer in a cased gearing. The control system comprises a cam disc rotating with the belt shaft, coupled to the toothed lock washer and inertially formed to form the webbing-sensitive controller with external gearing for the engagement of a sensor lever of a vehicle sensor arranged on the belt retractor, whereby at least one catch lever is provided controlled by the rotation of the belt shaft and rotatable between an engaged and a disengaged position for switching the vehicle sensor off in a function range in which almost the whole of the seatbelt is retracted onto the belt shaft.
