초록

A gas generating composition is disclosed for generating nitrogen gas free from noxious and toxic impurities consisting of an alkali metal azide, at least a stoichiometric amount of a metal oxide or a mixture of metal oxides and an ammonium perchlorate burn rate enhancer. The nitrogen gas can be used to inflate an impact protection air cushion of an automotive restraint system.

청구항

A solid composition for generating nitrogen gas free from noxious and toxic impurities consisting essentially of a mixture of (a) an alkali metal azide; (b) a primary oxidizer consisting essentially of at least a stoichiometric amount of a metal oxide containing sufficient available oxygen to substantially fully oxidize the alkali metal of the azide, said metal oxide being selected from the group consisting of oxides of iron, nickel, manganese, copper, cobalt, titanium, and tin; and (c) an ammonium perchlorate burn rate enhancer for enhancing the burn ra...
