Abstract
A two-part igniter for inflators used to inflate inflation devices such as air bags, lift rafts, slide chutes, and the like which includes a heterogeneous mixture of an ignition material and a consolidated mass of either i) a pyrotechnic component or ii) a composite propellant. The ignition material can be in a granular form or pelletized. The pyrotechnic component or composite propellant is provided as a pellet which is in immediate contact with the ignition material. The pyrotechnic component or composite propellant lowers the auto-ignition temperature of the two-part igniter. The two-part igniter can be used in inflators which generate all inflation gases from gas-generating compositions and in inflators which include a supply of stored pressurized inflation gases.
