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

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.

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.

Tensioning drive for a safety belt device

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.

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.

Belt retractor with axial securing and method for the production thereof

A belt winder for safety belts has a spindle (,) for the winding up of the safety belt (,) and a rotatable latching flange (,) which can be latched with respect to a fixed base frame (,). A torsion bar (,) is rotationally fixedly connected at its one end to the spindle (,) and is rotationally fixedly connected at its other end to the latching flange (,). A further torsion bar (,) is provided, which can be selectively switched in.

Belt winder

An arrangement for the attachment of a belt to a reel of a safety belt reeling mechanism has a shaft (10') and a reel (12') arranged coaxial to the shaft with a belt (14') attached to the reel (12') forming a closed loop (16') at its end. A securing pin (18') extending transverse to the direction of the belt is provided in the loop and is not formed by the shaft (10').
