Abstract
A safety belt retractor comprises a frame, a belt reel rotatably mounted in the frame, and a rotary pretensioner drive adapted to be drivingly coupled to the belt drum. A force limiting torsion rod is connected to the belt drum for joint rotation. Blocking pawls are pivotally mounted on the torsion rod for cooperation with an internally toothed ring rigidly connected to the frame and surrounding the blocking pawls. The blocking pawls are spring biased to neutral positions out of engagement with the toothed ring. Retarding mechanism act on the blocking pawls to retard their movement out of a belt drum blocking position in engagement with said toothed ring to the neutral position.
