Abstract
A gas generator 10 includes an auto-ignition/booster composition 212 that contains a metal chlorate such as potassium chlorate as an oxidizer, a carboxylic acid such as DL-tartaric acid as a primary fuel, a secondary oxidizer such as strontium nitrate, and if desired, a secondary fuel such as 5-aminotetrazole. The auto-ignition/booster composition 212 and a separate provision of ammonium nitrate or phase stabilized ammonium nitrate 228 are provided within a single combustion/decomposition chamber 222 for the production of gas, upon actuation of the gas generator 10. Vehicle occupant protection systems 180, containing the gas generator 10, are also provided.
Claims14
A gas generator comprising:
- a housing;
- a combustion/decomposition chamber within the housing;
- an auto-ignition/booster composition contained within the combustion/decomposition chamber;
- and
- ammonium nitrate or phase stabilized ammonium nitrate contained as a neat compound within the combustion/decomposition chamber and in operable and vapor communication with said auto-ignition/booster composition, said ammonium nitrate or phase stabilized ammonium nitrate separate from but adjacent to said auto-ignition/booster composition;
- wherein upon actuation of said gas generator, the auto-ignition/booster composition is ignitable to initiate decomposition of the ammonium nitrate or phase stabilized ammonium nitrate within the combustion/decomposition chamber.
A gas generator comprising:
- a housing;
- a combustion/decomposition chamber within the housing;
- an auto-ignition/booster composition contained within the combustion/decomposition chamber;
- and
- ammonium nitrate or phase stabilized ammonium nitrate contained within the combustion/decomposition chamber and in vapor communication with said auto-ignition/booster composition, said ammonium nitrate or phase stabilized ammonium nitrate is provided neat and separate and discrete from but juxtaposed to said auto-ignition/booster composition.
