Abstract
An airbag initiator having an ignition charge and a low temperature ignition charge in an inner case and a metal header closing the inner case, a glass seal providing feed through of one or more electrical connections to the ignition charge through the header. The seal is preferably formed using glass material. A ceramic base supports the header and their spaced relationship maintained by a single continuous glass seal. The ceramic base and glass seal electrically isolates the header and ignition charge against accidental ignition. The ceramic to glass to metal seal provides protection against leakage of unfiltered gas from the inflator system. A ferromagnetic pressed material is assembled into the ceramic base and it's spaced relationship to the ceramic body and the electrical connections are maintained by a single continuous glass seal.
