A multi-composition pyrotechnic material is provided for an inflatable restraint device (for example, an airbag system or pretensioner for a vehicle). The multi-composition pyrotechnic material can be a gas generant, a micro gas generant, or an igniter, for example. The multi-composition pyrotechnic material comprises a first pyrotechnic material that defines one or more void regions. A second pyrotechnic material, compositionally distinct from the first pyrotechnic material, is introduced into at least one of the void regions and forms a second region of the pyrotechnic materials. The second composition can be introduced to the void regions in the form of a slurry. Methods of forming such multi-composition pyrotechnic materials are also provided.

An airbag module has an inflator activated via an electrical connector. The inflator includes an initiation assembly having an initiator and a receptacle that retains the connector. The initiator may have a single, center pin. The initiator may be encased by a body and cover, which may be attached together by molding, vibratory welding, electromagnetic welding, or snap fitting. The connector may have projections that extend from a main body to facilitate retention of the connector by a collar, washer, a retainer attached to the body, or by the inflator housing. The body may be seated in a collar having an annular ridge that presses into the body to form a seal. The connector may have a rib designed to mesh with splines of the receptacle to enable engagement of the connector with the receptacle in multiple orientations, while preventing relative rotation between the connector and the initiator after assembly.
