The invention relates to a belt retractor for a safety belt, having: a belt reel () for winding up the safety belt; a locking base () 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.

Belt retractor

An occupant protection device including a pyrotechnical gas generator and a safety valve operating in a temperature-dependent manner and leading to the outside is connected to the gas generator. A sealing element of the safety valve is formed by a pin that includes a pin head, which is inserted from inside into a hole in a wall of a supply element such that the pin head bears against the inner face of the wall. A pin end, which is located on the outer face of the wall and protrudes outwardly through the hole, is plastically reshaped, so that the cross section of the pin end is larger than the cross section of the hole thereby forming a sealing portion which is larger in cross section than the cross section of the hole.

Occupant protection device comprising safety valve

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.

Seat 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.
