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: The invention relates to a tensioning drive (10) for a safely belt device having: a gas generator (20), a drive wheel (30) and a supply pipe (40) which connects the gas generator (20) and the drive wheel (30), there being provided in the supply pipe (40) a plurality of pushing members (50) which are accelerated after the gas generator (20) has been activated and which drive the drive wheel (30), and at least one of the pushing members (60) completely or at least partially sealing the supply pipe (40). According to the invention, there is provision for the tensioning drive (10) to be constructed in such a manner that the sealing action of the at least one sealing pushing member (60) is ended or reduced after a predetermined distance has been travelled.

Abstract: The invention relates to a belt retractor for a seat belt, with a belt reel (110) for winding up and unwinding the seat belt, and a lockable locking base (100) connected to the belt reel. According to the invention, it is provided that an inner element (10) having a predetermined outer contour (30) is held rotatably in an outer element (40) having a predetermined inner contour (50), the outer contour or the inner contour having at least one deformable section (R1-Rn) by means of which the inner element and the outer element interact and which is deformed in the event of a relative rotation of the two elements, and the inner element being connected to the belt reel and the outer element being connected to the locking base or, conversely, the inner element being connected to the locking base and the outer element being connected to the belt reel.
