Abstract
An improved ignition system for vehicle airbags is described. This invention includes a novel means for venting igniter material gases in such a manner as to more evenly distribute the flow in a more disperse manner, thereby permitting the gas generant to burn more uniformly throughout the generant bed. This invention by venting igniter gases more efficiently produces improved airbag ballistics, namely lowered average airbag deployment delay and increased consistency of operation.
