Abstract
An air bag inflator is provided with a new and useful auto-ignition device. The auto-ignition device comprises a thermoelectric battery, preferably located outside of the inflator housing. The thermoelectric battery is adapted to become electrochemically active in a predetermined temperature range (e.g. 300.degree.-400.degree. F.), and to provide an electrical signal which actuates the inflator.
