<p>An electrothermal gas generating device (16) for inflating the air cushion of an occupant restraint system (11) of the 'air bag' type. Upon sensing a deceleration (10) above a predetermining threshold level a discharge voltage (13) is applied between electrodes (28) within the electrothermal device (16) which sustains a current arc therebetween, creating a plasma jet which flows into a chamber containing a solid or liquid reactive material (34). The reactive material (34) is converted into gas by the high temperature, high pressure plasma jet. The gas created then flows into and inflates the air cushion (18).</p> |
