Reel for automatic safety belts for vehicles, especially motor vehicles

A reel arrangement for automatic safety belts of motor vehicles, the arrangement including roller means for accommodating the safety belt rotatably mounted in a housing, spring means connected to the roller means for providing a force counteracting a withdrawal of the safety belt from the roller means, and means for automatically locking the roller means upon the safety belt being subjected to high belt forces, characterized in that a gear means is connected to the roller means so as to be rotatable therewith, a rotatably mounted drag disk means is eccentrically disposed with respect to said gear means so as to enable the gear means to rotate relative to the drag disk means in a belt extraction direction, said drag disk means including a bearing surface means for carrying an engagement means for engaging said gear means in a belt take-up direction, an additional spring means connected with the drag disk means for exerting a force upon the drag disk means in opposition to the force of the spring means connected to the roller means thereby providing a reduced tension in the safety belt, stop means provided on the housing for limiting a rotational movement of the drag disk means, two additional spaced stop means are provided on the drag disk means and are adapted to come into engagement with said stop means on the housing, curved control and guide track means provided on the housing, and in that a guide means is provided on the drag disk means and cooperates with the curved control and guide track means for guiding a rotational movement of the drag disk means.
