초록

An electrically actuatable initiator (10) for an air bag inflator (20) includes an electrically sensitive ignition charge (280) disposed in an electrically conductive ignition cup (290). A plastic insulation cup (320) overlies the ignition cup (290). The insulation cup (320) electrically insulates the ignition cup (290) to block the flow of electric current into the ignition cup to prevent unintended actuation of the ignition charge (280). A locking ring member (380) is made from a shape-memory alloy which shrinks in diameter when heated above a predeter...
