Abstract: The present invention includes a gas generator 10 that incorporates a gas generating composition 12 and a scavenging additive 16 in heterogeneous but vapor/gaseous communication with the gas generating composition 12. The scavenging additive retains moisture/contaminants typically evolving over time at relatively higher temperatures. The present invention further includes a gas generating system 180 incorporating the gas generator 10.

Abstract: Gas generant compositions contain the mono-ammonium salt of bis (1(2) H-tetrazol-5-yl)-amine, an oxidizer such as phase stabilized ammonium nitrate, and a first additive selected from fumed oxides such as fumed silica. Gas generators 10 and gas generating systems 200 incorporating the compositions are also contemplated.

Abstract: The present invention generally relates to gas generant compositions for inflators of occupant restraint systems, for example. A gas generating composition 12 formed in accordance with the present invention includes a carboxyl alkyl cellulosic binder. A vehicle occupant protection system 180, and other gas generating systems, incorporate the compositions of the present invention.

Abstract: An inflator (10) for use in an inflatable vehicle occupant protection system. The inflator (10) includes a longitudinal enclosure (22) and a first gas generant (24) positioned along the enclosure (22). Enclosure gas exit apertures (40) are arranged along the enclosure (22) to enable fluid communication between the enclosure (22) and an exterior of the enclosure. and to provide controlled venting of combustion gases from the enclosure (22) as the first gas generant composition (24) burns, thereby controlling the speed and direction of combustion propagation of the first gas generant. Combustion of the first gas generant (24) results in an inflator housing internal pressure of at least a first predetermined minimum internal pressure.
