ABSTRACT:
The drive means of the passive safety belt is provided with a coupling which is disposed between the takeoff side of the worm gearing and a cable drum (28) and which is formed by a toothed slider (20) and two internally toothed rings (29, 30) at the inner face of the cable drum (28). Said coupling is controlled by an inertia disk (25) in whose radial grooves (23, 24) guide studs (21, 22) of the toothed slider (20) are guided slidingly. The coupling is not engaged until an adequately high drive speed is reached, said engagement being effected in that the toothed slider (20) is moved radially outwardly and with one of its coupling teeth (31, 32) comes into engagement with the corresponding internally toothed ring (29, 30). When the coupling is disengaged the end fitting of the safety belt can be easily displaced by hand.
