초록

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 t...
