ABSTRACT:
A reel arrangment for automatic safety belts of motor vehicles which include a roller rotatably mounted in a housing with the roller being subjected to the action of a spring in such a manner that the spring counteracts a withdrawal of the belt. A locking device is provided for locking the roller at high belt forces with a drag disk being mounted eccentrically with respect to a gear nonrotatably connected to the roller. The drag disk includes an engagement arrangement on a bearing surface thereof which cooperates with the gear in a belt take-up direction and is subject to the action of an additional spring in the belt extraction direction. A stop is provided on the reel housing for delimiting the rotational movement of the drag disk with the stop cooperating with two matching stops on the spring-loaded drag disk. The reel housing includes a curved control and guide track or surface which cooperates with a guide pin on the drag disk.
