Abstract

The invention relates to a belt rectractor (10) for a seatbelt of a motor vehicle. The belt retractor (10) comprises a belt spool (14) which is rotationally connected to a belt spool-side end of a torsioning rod, said torsioning rod being operatively connected to a locking mechanism (20) at a locking mechanism-side end. In a locked state, the locking mechanism-side end of the torsioning rod is rotationally fixed to a frame (12). The belt spool-side end can then be rotated relative to the locking mechanism-side end in an unwinding direction (16) under the effect of torsion from the torsioning rod. The belt spool (14) is additionally rotationally fixed to the frame (12) in the unwinding direction (16) in a stopped state of a stopping mechanism (22). The stopped state is set of the belt spool-side end is rotated by a specified number of rotations relative to the locking mechanism-side end in the locked state of the locking mechanism (20). The stopping mechanism (22) comprises a locking pawl which is mounted on the belt spool (14).
