Coupling system for the winding shaft of a safety belt with a retightening device, with flexible tension means which is in functional connection with a driving device, for instance, a power accumulator, and with a tension means roll connected to the shaft to be driven. The tension means is looped around the tension means roll firmly connected to the shaft to be driven, with radial play preferably several times. The free end section of the tension means is subjected by a brake element to a predetermined braking force. Upon activation of the driving device, the looping section of the tension means is contracted and is coupled by the loop friction to the tension means roll. |
