초록

A nonazide gas generant that may be used in an inflation device, such as a vehicle passenger restraint system, comprising a hydrated or anhydrous mixture of nonazide fuel, an oxidizer and a quantity of copper phthalocyanine, otherwise known as Monarch Blue and/or azodicarbonamidine dinitrate. Specifically, the nonazide gas generant composition of the present invention may include phase stabilized ammonium nitrate (PSAN), high bulk density nitroguanidine (HBNQ), one or more nonazide fuels, a quantity of copper phthalocyanine and/or azodicarbonamidine dini...

청구항

[ We claim:] [1.] A gas generant composition for a gas generator of a vehicle passenger restraint system, said gas generant composition comprising a hydrated or anhydrous mixture of:(i) high bulk density nitroguanidine;(ii) one or more nonazide fuels;(iii) an oxidizer which includes a phase stabilized ammonium nitrate; and(iv) an amount of copper phthalocyanine sufficient to sustain combustion of the gas generant composition at ambient pressure of about 100 psi or less.
