The disclosure relates to a bridgewire initiator used to ignite a booster charge in an airbag inflator. A pair of connectors are electrically connected to a bridgewire disposed within a charge holder containing an ignition composition. The ignition composition is biased against the bridgewire by an output cup having a concave end telescoped over the charge holder. When firing current is applied to the connectors the bridgewire is electrically heated thereby igniting the booster charge.
[ I claim:] [1.] A bridgewire initiator comprising;an electrically conductive cylindrical header having a radial flange at one end thereof;a first connector electrically connected to said header;a second connector;a bridgewire having one end electrically connected to said header and an opposite end electrically connected to said second connector;a cylindrical charge holder telescoped over said header and having a radial flange abutting the radial flange of said header;an ignition composition disposed internally of said cylindrical charge holder and juxta...
