The invention relates to a belt retractor for winding up and unwinding a safety belt, with at least one force transmission element which is held by a first part of the belt retractor and which can be connected to a second part of the belt retractor, the force transmission element being held in a recess of the first part in such a way that it can be pressed axially into the recess of the first part, with the result that the connection to the second part is broken.

Belt retractor

The invention is concerned, inter alia, with a belt retractor () for a seat belt, with a belt reel () for winding up and unwinding the seat belt, and a lockable locking flange () which is connected to the belt reel and, prior to a locking action, is rotated together with the belt reel and, after a locking action, is blocked in its rotational movement. According to the invention, it is provided that the locking flange and the belt reel are secured against relative axial displacement.

Belt retractor with axial securing and method for the production thereof

A belt force limiter which limits the belt force through the twisting of a torsion bar. The belt force limiter includes a flange, a reel for winding and unwinding the belt, as well as the torsion bar. Additionally, a shear pin or a deformable pin may be provided for locking the flange and the reel together, so that the relative turning of the flange and reel is prevented or impeded until the tensile force acting on the belt exceeds a preset level momentarily or over a preset period of time. Thus the force limitation is delayed or graduated. Furthermore, in a method for reducing the danger of injury to a vehicle's occupant by means of a restraining system the belt force is allowed to increase to an elevated level of force and then the belt force diminishes again before the belt force limitation begins.
