A belt retractor having a belt reel, a safety belt which can be wound thereon to form a wound belt, a pyrotechnic belt tensioner having a drive device which is guided in a tube and can be driven to perform a drive movement, and at least one first further assembly arranged coaxially to the rotational axis of the belt reel and in series with the belt reel, a safety belt which can be wound thereon to form a wound belt, and at least one first assembly, wherein the tube has a straight linear section which extends parallel to the rotational axis of the belt reel and the longitudinal axis of the assembly and is arranged on the side of the belt reel.

Belt retractor

A belt retractor for a motor vehicle seat belt, with a belt shaft () in a housing frame, a profile head () which can be locked and a force limitation device () with a first end () coupled to the profile head () and a second end () is coupled to the belt shaft () and which allows a force-limited relative rotation of the belt shaft () with regard to the locked profile head (). A connection tube () surrounds the force limitation device () with a locking hook (), which during the relative rotation with regard to the profile head () slides over an external circumference of the connection tube () and on reaching a predetermined angle of rotation of the belt shaft () engages in a locking groove () on the connection tube (), the coupling the connection tube () to the belt shaft () The connection tube () is produced in one piece with the profile head (), so that on engagement of the locking hook () in the locking groove () the belt shaft () is locked via the profile head () to the housing frame in a non-rotational manner.

Belt retractor having a force limitation device

A seat belt retractor for a safety belt of a motor vehicle having a belt shaft () rotatably mounted in a frame, a profile head () lockable in relation to the frame, a load limiting device () located between the profile head () and the belt shaft () for enabling the belt shaft () to undergo a load limited rotation in the belt webbing extraction direction (A) with the profile head () being locked and a load limiting level predetermined by the load limiting device () being exceeded.
