Abstract: A self-locking seat belt retractor includes a blocking system for a seat belt winding shaft that is actuated in an at least vehicle-sensitive manner, in which, in the event of triggering, a sensor mass mounted in a vehicle-sensitive manner moves a locking lever with its engagement tip into a trigger position in engagement with the toothing of a control disk, as the result of which the control disk in its joint rotational motion with the belt winding shaft is stopped and the blocking system is activated. The sensor mass is situated in a support part on a contact surface, and when vehicle accelerations occur the sensor mass in the support part is movable on the contact surface by inertial control from a neutral position into the trigger position. The support part together with the sensor mass situated therein is situated in a housing that includes the control disk.

Abstract: A self-locking safety belt retractor has a blocking apparatus for a belt shaft mounted rotatably in a housing. The blocking apparatus includes a pawl inserted into a recess of the shaft front of the belt shaft which can be pivoted radially outward into engagement with the blocking apparatus. A blocking gearing (12) is oriented with respect to stop surfaces of the pawl (16) and to force transmission surfaces (25, 32) of the recess (15) such that, when the gear teeth of the pawl (16) are engaged in the blocking gearing (12) under normal load, a force acts between the blocking gearing (12) and the belt shaft (13) in a radial direction. If the load increases in a crash case, a force is transmitted in the circumferential direction due to plastic deformation of at least one housing gear tooth (28, 26) of the blocking gearing (12).

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.

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.

Abstract: A self-locking safety belt retractor with a belt band sensitively and/or motor vehicle sensitively controllable blocking apparatus for a belt shaft mounted rotatably in the housing segments of a U-shaped housing, whereby the blocking apparatus includes a pawl inserted into a recess of the shaft front of the belt shaft which can be radially swivelled out up to engagement into a blocking apparatus constructed on the allocated housing segment is characterized in that the blocking gearing (12) on the one hand and the stop surfaces of the pawl (16), as well as the force transmission surfaces (25, 32) of the recess (15) of the shaft front (14) on the other hand are oriented in relation to each other such that when the gear teeth of the pawl (16) are engaged in the blocking gearing (12) under normal load, a transmission of force takes place between the blocking gearing (12) and the belt shaft (13) in a radial loading direction, and in that in the event of a load rising in a crash case, the load additionally arising

Abstract: The inventive device for fixing a seat belt winder is fixed to the part of a motor vehicle. The plate of the housing of the winder is provided with at lest one fixing hole for receiving a screw connection which maintains the vehicle part embodied therein. The housing of said seat belt winder is arranged in such a way that it is rotatable with respect to the fixing hole of the vehicle part, thereby enabling the winder to be automatically oriented in a direction of a force of a belt which moves at an angle with respect to the axis of the shaft. Said fixing device is characterised in that the housing (10) of the winder is rotationally maintained on the holder part (13, 19, 25) which can be firmly connected to the vehicle part (40).
