ABSTRACT OF THE DISCLOSURE A metal bridge initiator, with or without a spark gap feature, for firing an air bag inflator is deposited on a thin plastic film substrate. The bridge can be tuned by adjusting the width and thickness of the substrate. The bridge is of compact size enabling an increase in the strength of the inflator in the initiator area thereof. If there is an initiator structural failure, the very small feed through slot into the interior of the inflator will plug up with the products of combustion of the inflator. The intimate contact between the deposited metal bridge and plastic substrate makes the initiator resistant to vibration, bending and damage. The method of manufacturing is simpler than for conventional inflator initiators and is adapted to mass production.
