Abstract

The present invention generally relates to auto-ignition/booster compositions for inflators 10 of occupant restraint systems 180, for example. An auto-ignition/booster composition in accordance with the present invention includes an auto-ignition composition 17 combined with silicone. When uncured silicone is added to a mixture of the dry granulated constituents of both the auto-ignition and booster components, an extrudable or thixotropic mixture is produced. The uncured mixture may then be applied to any desired surface 21 within an associated gas generator 10 within a vehicle occupant protection system 180, for example, thereby simplifying gas generator 10 manufacture. A gas generating system 150, 200 incorporating the present composition 17 is also contemplated.
