| abstract |
The present invention generally relates to a gas generant composition, for example, for an inflator of an occupant restraint system. The extrudable pyrotechnic composition includes a polyvinyl azole used in an airbag gas generator. Fuels include 5-amino-1-vinyltetrazole, poly (5-vinyltetrazole), poly (2-methyl-5-vinyl) tetrazole, poly (1-vinyl) tetrazole, poly (3-vinyl) 1,2, 5-oxadiazole and poly (3-vinyl) 1,2,4-triazole) can be selected from exemplary polyvinyl azoles. The oxidant is combined with the fuel and preferably contains phase stabilized ammonium nitrate. A novel method of forming a composition is also shown, where various ingredients are dissolved and / or wetted and then cured in a polyvinyl azole matrix, thereby forming a closer combination within the gas generant composition . The vehicle occupant protection system 180, and other gas generation systems, incorporate the compositions of the present invention. |
