Abstract
A novel compound, used for example, as a gas generating fuel, is defined as a compound having the structural formula of R.sub.3--R.sub.1--R.sub.2, wherein R1 is a benzene ring with nitro substitution, R2 is a tetrazolyl group with a C--C bond to the benzene ring, and R3 is a tetrazolyl group with a C--C bond to the benzene ring. Other fuels used in the gas generant compositions of the present invention include methylene bi(tetrazole); and 2,3-bis(tetrazolo) pyrazine. A method of making the compound is also provided. Gas generant compositions 12 containing these fuels are provided 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.
