ABSTRACT:
For a self-locking reeling device for a safety belt, especially for motorized vehicles, with a vehicle-sensitive and/or belt-sensitive control system for the locking member, the switching point of the locking device is exactly determined. The locking device consists of a rocker arm with a switching arm which when, the safety belt is removed from the reel to a predetermined unwinding stage, engages the outer toothing of the control disk of the belt-sensitive and/or vehicle-sensitive control system and which, when the safety belt is rewound onto the reel, is in a release position for the control disk. The rocker arm is pivotably arranged about the axis of the reeling shaft and both ends have gear wheels that intermesh with a further gear wheel fixedly connected to the reeling shaft. The gear wheel that is fixedly connected to the reeling shaft as well as the gear wheels connected to the rocker arm are each provided with switching lugs which at the predetermined unwinding stage of the safety belt engage one another and pivot the rocker arm due to a pulling force of the safety belt or the winding spring.
