Abstract
A fuel component for an airbag inflator, dinitrosalyicylic acid and derivatives thereof, is used as a primary fuel in a gas generating composition 12. A novel gas generating composition 12, containing the primary fuel, and phase stabilized ammonium nitrate is also provided. The fuel component may be contained within a gas generant composition 12, within a gas generator 10. The gas generator 10 may be contained within a gas generating system 200 such as an airbag inflator 10 or seat belt assembly 150, or more broadly within a vehicle occupant protection system 180.
Claims12
