Belt-retractor housing shell

A belt retractor for a vehicle safety belt has a frame, a belt spool for the safety belt which is rotatably arranged in the frame, a locking disc which is arranged on the belt spool and is connected therewith through an energy absorption element, and a blocking mechanism which allows to block the locking disc against a rotation in the unwinding direction of the safety belt in the frame. A detent is provided which is movably arranged in the belt spool and can prevent a rotation of the locking disc relative to the belt spool as a function of its position.

Belt retractor for a vehicle safety belt

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