Belt retractor and a belt-retractor spring-cassette housing for a belt retractor. The belt-retractor spring-cassette housing can be installed in a particularly simple and therefore cost-effective manner. The belt-retractor spring-cassette housing has a spring core and a driving spring which is held in the spring core, the belt-retractor spring-cassette housing and/or the spring core are designed symmetrically so that the driving spring can have any desired torque direction.

A belt retractor for a seat belt includes a belt reel, an eccentric disc connected to the belt reel, a cam disc driven by the eccentric disc, and a blocking pawl. The blocking pawl, in a blocking position, blocks a toothed ratchet wheel, and, in a release position, leaves the toothed ratchet wheel unaffected. The blocking pawl may be switched from the release position into the blocking position and conversely from the blocking position into the release position with the cam disc. For the belt retractor to be independent of tolerances, provision is made for the cam disc to have an engaging cam for engaging the blocking position of the blocking pawl and a disengaging cam for engaging the release position of the blocking pawl.
