The invention relates to an actuator comprising an actuator element movably supported at an actuator housing, a pyrotechnic pressure element to move the actuator element and a control means to control a force exerted onto the actuator element by the pressure element to move the actuator element.

Pyrotechnic actuator

The present invention relates to a an actuation unit having a triggering device for the moving of a headrest into a predetermined position, with the triggering device comprising a pyrotechnic gas generator and a triggering member which is movable from a blocking position into a release position.

Triggering device

An apparatus for the cutting of an electrical conductor has an electrical conductor arranged in a housing, a pyrotechnic drive and a cutting device. After the triggering of the drive, the cutting device enters into engagement with the conductor to cut it.

Apparatus for the cutting of an electrical conductor

An igniting/firing element includes a casing (,) receiving electrical junction lines connected to an igniting jumper (,) on a chip (,) provided with at least one igniting unit (,). In order to allow for the element to be universally used and to avoid uncontrolled discharge, it is suggested that the junction lines be designed in the form of pins, which are led to the casing (,) through a glass seal, and that the casing bottom (,) be a metal body (,) in which bores (,) are provided for said glass seals (,) to pass through, and that the metal body be positive-fit to the plastic body (,) covering the peripheral wall of the casing (,) and wrapping the pin tops (,) emerging from the glass seal (,).

Ignition/firing element with an ignition bridge arranged on a chip

The invention relates to a gas generator for an air bag (,) including a cartridge (,) containing a gas-generating charge of solid material (,) and a storage reservoir (,) containing a storage gas (,). To trigger gas production the charge of solid material (,) is ignited. The resulting gas pressure tears off the front face (,) of the cartridge (,) along a peripheral notch (,). A sliding element (,) connected to the front face (,) pierces a sealing element (,) of the storage reservoir (,). A guiding channel (,) in which the front face (,) is guided in the manner of a piston, opens into a flow zone (,). When the front face (,) has reached the flow zone (,), reaction gas flows around the front face (,) into openings (,) in the tube-shaped sliding element (,). The reaction gas then flows into the storage reservoir (,) where it is mixed with the remaining storage gas. Because the control for releasing the two gases depends entirely on the trajectory, the operating performance of the hybrid gas generator is exact and reproducible.

Hybrid gas generator for airbag

A hybrid gas generator for an air bag (,) including ignitable gas-producing solid charge (,) placed in combustion chamber, a storage chamber (,) containing a gas (,) and a closed by a first bursting disk (,), a breakable separating wall (,) limiting the combustion chamber, which is connected to a hollow sliding piston (,) to perforate the first bursting disk (,) and a second bursting disk (,) in the separating wall (,) between the combustion chamber and the cavity (,) of the sliding piston (,). In order to construct the generator in a simpler and more economical form, the solid charge (,) is placed in a pyrotechnic cartridge that can be mounted separately the separating wall (,) forms the frontal border of the cartridge (,), a round notch (,) is placed on the round wall of the cartridge (,) serving as predetermined breaking point to break the separating wall (,) and the second bursting disk (,) is formed by a thinning on the separating wall (,).

Hybrid gas generator for an air bag with a mechanical opening mechanism for the storage chamber

An ignition unit is provided with an internal housing defining a chamber in which an ignition charge and an ignition element igniting the charge are accommodated. The housing defining the chamber consists of a cover and a container which are connected to one another along a circumferential groove. A distributor housing is mounted on to the housing forming the chamber, in which distributor housing gas outlet openings are provided which are closed by a cap-shaped cover of the chamber. The V-shaped circumferential groove represents a predetermined breaking or separation position of the chamber, for which reason the cover is separated from the container when the ignition charge is ignited. The cover moves away from the container into a space until it strikes the upper end of the distributor housing. With its movement relative to the distributor housing, the cover releases the gas outlet openings so that the gases and flames can emerge from the ignition unit.
