Abstract: 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.

Abstract: A seat belt retractor for a safety belt including a seat belt spindle for winding up and unwinding the safety belt and a tensioning drive. The seat belt spindle includes a gas generator, a drive wheel and a supply pipe which connects the gas generator and the drive wheel. A plurality of thrust members are present in the supply pipe which, after triggering the gas generator, are accelerated and indirectly or directly drive the drive wheel for winding up the safety belt. An inertia coupling is arranged between the drive wheel and the seat belt spindle. The inertia coupling comprises coupling elements which, during an acceleration of the drive wheel, pivot outward and are directly or indirectly coupled to the seat belt spindle.

Abstract: 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.

Abstract: A safety belt apparatus for a vehicle, having a belt reel, a belt buckle, a belt redirection apparatus mounted on the B-post of the vehicle. The apparatus also includes, a belt-force limiter with a torsion bar and a belt tensioner. In the event of an accident, the belt tensioner is triggered, and pretorsioning of the torsion bar is simultaneously effected. The pretorsion is preferably brought about by the forces that arise during belt tensioning. The pretorsion allows for the force limitation to start at an optimum force level with regard to the retention force and the protection of the occupant.

Abstract: A drive for a belt tensioner for safety belts has a drive chamber formed between two plates. A drive band whose two ends are fastened to a drive shaft such that the drive band forms a loop which can be exposed to expanding gas discharged from a gas outlet such that the drive band winds off and drives the drive shaft. The drive band is fixed to the plates by a fixing apparatus at a position disposed between its ends.
