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...
An electrically actuatable initiator comprising: a retainer; at least one terminal for electrical connection with vehicle circuitry; means for supporting said terminal in spaced relation to said retainer and for providing electrical insulation between said terminal and said retainer; a bridgewire associated with said terminal for, when electrically actuated by current from said terminal, generating thermal energy; an ignition charge ignitable by said thermal energy; a metal ignition cup enclosing and supporting said ignition charge, said metal ignition c...
