Abstract

A force limiter is provided on a belt retractor. The belt retractor comprises a belt spool (1) that is rotatably mounted in a frame (10) and has at least one flange (1a) and a disk (2) that can be non-rotatably blocked on the frame. The disk (2) and the flange (1a) of the belt spool (1) are adapted to be coupled by a cutting element (3). The cutting element (3), with a relative rotation between the disk (2) and the flange (1a), comes into a coupling position and cuts material when the relative rotation is continued.
