Abstract
An electrically actuatable initiator (10) for an air bag inflator (20) includes an ignition charge (190) which is ignitable by thermal energy from a resistive element (130). The resistive element (130) is formed on a substrate (110) as part of a chip (100). The chip (100) is secured to a header (40) by a portion (156, 158, 160, 162) of a glass to metal seal (150). The resistive element is electrically connected to terminals (60, 90) of the initiator (10) by brazing with braze preforms (170, 180). The brazed electrical connections are made during the same heating operation in which a glass preform is melted to form the mechanical connection provided by the glass to metal seal (150).
