Abstract
A safety belt retractor is provided with a belt pretensioner device acting via a clamping roller coupling mechanism. A torsion rod (30) is arranged in the force flow path between the coupling mechanism and the belt drum (12) of the retractor, so that after tightening of the belt such torsion rod is twisted about its axis under the load transmitted by the belt with the consumption of energy. Owing to the plasitic deformation of the torsion rod (30), it is possible for the load peaks occurring following tightening of the belt in the belt system to be absorbed in order to increase the efficiency of the safety belt system.
