A belt retractor () of a seatbelt system comprises a belt tensioner () which is adapted to rotate a belt reel () of the belt retractor () accommodated in a belt retractor frame (), wherein the belt retractor frame () is closed by a cover () on the tensioner side in the area of the spindle of the belt reel () and in the cover () a bearing for the belt reel () is provided. The cover () includes a first pot-shaped cover part () which is mounted directly on the belt retractor frame () and has a side wall () merging into a flat portion (). In the flat portion () an opening () is spared and a second cover part () is provided which engages in the opening () in the first cover part () and on which a bearing () is formed in which an end () of the spindle of the belt reel () is supported.

Belt tightener

In a belt tensioner () for a seat belt comprising an elongate pressure reservoir (), a piston () movably supported in the pressure reservoir () in the longitudinal direction to which piston pressurized fluid can be applied and which in this way can be moved in a tensioning direction (S), a mechanical thrust means () interacting with the piston, the thrust means interacting with a gearwheel () and driving the same in the case of restraint, and comprising a stop () on which the piston () abuts in the tensioning direction in a final position, it is provided that between the piston () and the thrust means () a spacer () in the form of a separate member is provided which is dimensioned such that in the final position of the piston () the thrust means () is urged past the stop () by said spacer. Furthermore there is provided a method of mounting a belt tensioner of this type.

Belt tensioner and method for installing a belt tensioner

In the method for mounting an inflator () within a tube (), especially of a belt tensioner, wherein an end portion () of the tube () is formed radially inwardly so that a first contact surface () directed to the interior of the tube () occurs, prior to forming an annular stabilizing disk () is arranged between the first contact surface () and a second contact surface () configured at the inflator ().

Method for mounting a gas generator, and subassembly comprising a gas generator

A controllable clutch () for a belt tensioner () comprises a drive member (), a driven element () and a clutch pawl () that is movably supported on the input side () between a home position and an engaged position and in the engaged position couples the drive member () to the driven element (), wherein the clutch pawl () is tension-loaded in the engaged position.
