Abstract
A solid non-azide, non-toxic, substantially moisture-free nitrogen gas generating composition intended for use in the deployment of inflatable safety crash bags for driver and passenger protection in vehicles consists essentially of a metal salt of a non-hydrogen containing tetrazole compound selected from the group consisting of alkali metal salts and alkaline earth metal salts and an oxidizer containing nitrogen and a member selected from the group consisting of an alkali metal and an alkaline earth metal, the tetrazole being an azobitetrazole, and examples of the oxidizer being sodium nitrate, sodium nitrite and potassium nitrate.
