ABSTRACT:
A self-locking safety-belt reeling device has a reeling shaft on which a safety-belt is wound. A blocking device that is controlled by at least a vehicle-sensitive control mechanism and/or a safety-belt-sensitive control mechanism for blocking the safety-belt reeling shaft is provided. A tightening device acting on the reeling shaft comprises a tightener coupling. The tightening device further has a drive disk. The drive disk, upon activation of the tightening device, is driven in rotation by a drive device and coupled with the tightener coupling to the reeling shaft. A power limiter is connected to the safety-belt reeling device for limiting removal of the safety belt, whereby the power limiter is activated and deactivated depending on the operational states of the safety-belt reeling device and the tightening device. The power limiter during blocking of the safety belt reeling device is inactive and is activated only after completion of a tightening movement of the safety belt. Preferably, the power limiter is a torsion rod.
