The invention relates to a pyrotechnic detonator with an igniter support of plastic, which bears an ignition element. A cylindrical metal housing is fastened to the igniter support, into which the ignition reaches. A booster charge is arranged in the metal housing. To improve seal tightness and lower the manufacturing costs, for mechanical support a metal insert is integrated into the igniter support, the metal insert being encased by the plastic of the igniter support.

Pyrotechnic detonator with an igniter support of plastic with an integrated metal insert

A gas generator includes an ignition charge, at least one ignition element for igniting the ignition charge, a storage chamber containing a compressed gas, which storage chamber is closed by a closure element, and an impact element destroying the closure element under pressure. A piston is provided as the impact element, which piston, after the destruction of the closure element, forms an exit gap with the opening closed by the closure element. The cross-sectional area of which exit gap changes in according to the position of the piston.

Gas generator

The hybrid gas generator to inflate airbags comprises two combustion chambers (,), in each of which a solid material charge (,) is placed, and a storage chamber (,) containing a pressurized storage gas. The storage chamber (,) is connected to diffusion chamber (,) by a closing member (,) which can be perforated. The first solid material charge (,), and the second solid material charge (,) can, for instance, can be sequentially ignited by separate igniter elements (,), thereby determining the pressure accumulation.
