Abstract: 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.

Abstract: A seat belt device is provided. The seat belt device has a seat belt roller together with a locking device for locking the seat belt roller. The seat belt device furthermore has a guide pin which is moveably supported inside a guide link and is coupled to the locking device. The displacement of the guide pin inside the guide link depends on the direction of movement of the seat belt roller. The coupling of the pin to the locking device provides that locking of the seat belt roller is either brought about or prevented, according to the positioning of the guide pin in the guide link. The seat belt device makes it possible to ensure that seat belt locking is activated only when unreeling, and not when the set belt is being reeled in.
