Abstract: The invention relates to a recoil valve for the trigger capsule for the gas generator of a passenger restraint system in an automotive vehicle, in particular for the gas generator of an inflatable impact protection cushion (airbag), measures being taken in order to avoid a relative movement of the glass insulation or of the contact pin in the trigger capsule due to the released quantity of gas or during the ignition process.

Abstract: The invention relates to an ignition capsule for a gas generator of an occupant restraint system in a motor vehicle, in particular for the gas generator of an inflatable airbag, said ignition capsule comprising means for supporting extremely high pressures during ignition.

Abstract: A gas generator igniting capsule for air bags and belt tensioning means has one or more contact pins connected to an igniting element constructed as a glow wire, located in a first detonator layer of a multiple charge detonator construction.

Abstract: A self-powered fuze apparatus for a projectile containing an explosive charge which comprises a first housing containing a mechanical safety device for releasably preventing undesired movement of a detonator cup holder containing a detonator from an unarmed to an armed position wherein the detonator cup is shielded from the charge to be exploded in the unarmed position and the detonator cup communicates with the charge only in the armed position and the second housing adjacent the first housing containing an electronic safety means for sensing target impact and projectile launch and selectively passing a piezoelectrically generated firing current to the detonator cup only upon sensing a predetermined magnitude target impact only within a predetermined time after sensing the launch acceleration and only when the electronic means is electrically and mechanically connected to the detonator cup in the armed position.
