Belt retractor for a seat belt of a motor vehicle

Abstract

The invention relates to a belt retractor for a seatbelt of a motor vehicle, comprising a belt shaft which is rotatably mounted in a housing frame, a profile head which can be locked with respect to the housing frame, a multi-stage first force-limiting device, wherein the first force-limiting device is coupled to the profile head and to the belt shaft, wherein the first force-limiting device allows a force-limited relative rotation of the belt shaft with respect to the locked profile head, and comprising at least one second force-limiting device, wherein, in an initial state, the second force-limiting device is decoupled, so that the force-limited relative rotation of the belt shaft with respect to the locked profile head takes place without a force-limited involvement of the second force-limiting device.
