Abstract

A belt retractor for a vehicle safety belt has a frame, a belt spool for the safety belt which is rotatably arranged in the frame, a locking disc which is arranged on the belt spool and is connected therewith through an energy absorption element, and a blocking mechanism which allows to block the locking disc against a rotation in the unwinding direction of the safety belt in the frame. A detent is provided which is movably arranged in the belt spool and can prevent a rotation of the locking disc relative to the belt spool as a function of its position.
