ABSTRACT:
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.
