Abstract: The invention relates to a belt retractor for a safety belt, having: a belt reel (100, 200, 300, 400, 500, 600) for winding up the safety belt; a locking base (120, 220, 320, 420, 520, 620) which during normal operation is conjointly rotated with the belt reel and the rotary motion of which upon abrupt belt extraction is locked by means of a locking mechanism; and a belt force limiting installation which upon locking of the locking base permits relative rotation between the belt reel and the locking base. It is provided according to the invention that the belt retractor has a deactivation installation which after a predefined maximum relative rotary angle between the locking base and the belt reel blocks the relative rotation which is permitted between the belt reel and the locking base by the belt force limiting installation and, on account thereof, deactivates the belt force limiting installation.

Abstract: A belt retractor for a safety belt, having a belt reel for winding or unwinding the safety belt, and a belt force limiting installation which comprises a first and second torsion bar for limiting belt force. The belt retractor has a free-wheeling transmission which operates depending on the rotation angle and which after activation of the belt force limiting installation initially leaves the second torsion bar so as to be inactive, while the first torsion bar for limiting belt force is already being twisted, and the free-wheeling transmission activates the second torsion bar as soon as the free-wheeling transmission has been rotated about a predefined maximum free-wheeling rotation angle.

Abstract: The invention relates to a belt retractor for a seat belt having a belt reel for winding up and unwinding the seat belt and a torsion bar which is arranged outside the belt reel and is connected at one bar end to a switchable fixing device. The switchable fixing device keeps the bar end rotationally fixed in one state and permits rotation of the bar end in another state. The switchable fixing device has a displaceable piston which, with a piston portion, in a locking position, can secure the bar end against rotation and, in a release position displaced in relation to the locking position, releases the bar end.

Abstract: A tensioning drive for a safely belt device. The tensioning drive includes a gas generator, a drive wheel and a supply pipe which connects the gas generator and the drive wheel. A plurality of pushing members is included in the supply pipe. The pushing members are accelerated after the gas generator has been activated. The pushing members drive the drive wheel, and at least one of the pushing members completely or at least partially seals the supply pipe. The sealing action of the at least one sealing pushing member is ended or reduced after a predetermined distance has been travelled.

Abstract: A belt roller for a safety belt having a belt coil for winding and unwinding the safety belt. The roller includes a lockable locking base which is connected to the belt coil and which is suitable for blocking the belt coil in the event of an abrupt rotation of the belt coil in the belt unwinding direction. The roller also includes a force transmission element which couples the belt coil and the locking base in a locking position and is inactive in an unlocking position. The force transmission element has a base member and a shearing portion which can be sheared off.

Abstract: The invention relates to a belt retractor (10) for a seat belt, with a belt reel (20) for winding up and unwinding the seat belt, and a torsion bar (30) which is arranged outside the belt reel (20) and is connected at one bar end (32) to a switchable fixing device (50), the switchable fixing device (50), in one state, keeping the bar end (32) rotationally fixed and, in another state, permitting rotation of the bar end (32).
