Abstract

A belt retractor including a force limiter comprises a belt reel which is rotatably supported in a frame as well as a blocking unit counteracting a rotation of the belt reel and a force limiter between the belt reel and the blocking unit which permits a limited torsion of the belt reel against the blocking unit under load. The force limiter includes a damping element consisting of a cross-linked polymer which is sheared under load.
