Abstract

A belt retractor for a vehicle safety belt comprises a frame, a belt spool rotatably mounted in the frame, a locking catch arranged on the belt spool, a locking mechanism adapted to pivot the locking catch between an initial position and a locking position, a locking disc and a locking toothing. The locking toothing is arranged on the locking disc. The locking catch when in the locking position engages into the locking toothing of the locking disc so that the belt spool is locked with respect to the locking disc. The locking disc is connected to the frame by means of a holding device which allows a rotation of the locking disc relative to the frame only after a predetermined torque has been exceeded.
