1. In an occupant carrying vehicle having an occupant carrying location and structure spaced from said location, a crash restraint system for protecting an occupant in said location from impact with said structure, said system comprising:

  • a. a collapsed inflatable so disposed and mounted in said vehicle that upon being inflated the inflatable is positioned between said structure and said occupant carrying location;

    b. a gas source to supply an inflating gas for the inflatable;

    c. an electrically actuated initiating device for said gas source to cause said gas sourcE to provide gas to inflate said bag, and d. means to generate an electric current to activate said gas source initiating device, said current generator means comprising;

    1. a magnetized inertial mass, a releasable connection mounting said mass in the vehicle in a manner such that upon crash impact of a predetermined value said releasable connection releases said mass and said inertial mass is caused to travel a predetermined activating path;

    2. an inductance coil so disposed relative to the path of the inertial mass that a voltage is induced in said coil by movement of the inertial mass on its path, and 3. conducting means to connect said coil to the gas source initiating device, in a manner that upon crash impact a voltage is imposed from said coil across said initiating device to actuate said initiating device so that said gas source is caused to inflate said inflatable.
