A gas generator is provided, the gas generator having a propellant cushion that prevents movement of propellant wafers, tablets, or grains by providing a bias thereagainst. Furthermore, the cushion may be formed from a polyurethane-based foam material and if desired, a known oxidizer combined within the foam. Channels inherent within the polyurethane-based foam enhance the combustion of the main gas generant. Alternatively, the substituted polyurethane polymer combined with an oxidizer may be formed as a monolithic grain that provides autoignition and gas generant function in lieu of a primary gas generant or in lieu of an igniter composition, for example.

Foam-in-place pyrotechnic system

Disclosed are gas generating compositions and methods of making and used them.

Gas generating compositions and methods of making and using thereof

A novel composition containing a bi-tetrazole having a primary tetrazole ring substituted or connected to a second tetrazole ring by an aliphatic bridge such as an ethyl or ethylene bridge. The composition may be contained within a gas generator as a gas generating composition when combined with an oxidizer such as phase stabilized ammonium nitrate. The gas generator may be contained within a gas generating system such as an airbag inflator or seat belt assembly, or more broadly within a vehicle occupant protection system.
