Disclosed is a composition and method for the inflation of passive restraint systems, i.e., crash bags. The method, which uses the gases produced by the ignition of certain alkali metal azides in combination with certain metal halides for inflation of the bag, provides a non-toxic gas for inflation. Use of sufficient metal halide to provide halogen in an amount at least stoichiometric with the alkali metal prevents the formation of free alkali metal, the latter considered to be toxic and to present an unsuitable material in passive restraint systems. |
