초록

An air bag igniter including a foamed material, and an air bag assembly containing the same are disclosed. The foamed material is formed from a composition including, as ingredients, a polyfunctional isocyanate, a polymeric binder having a plurality of hydroxyl groups which are reactive with the polyfunctional isocyanate, a fuel source, an oxidizer, and a foaming agent which may or may not be retained in the foamed material.
