초록

An apparatus (2) for inflating an air bag (4) including a container (12) and a combustible material (20) disposed in the container. The combustible material (20) comprises a binder selected from the group consisting of cellulose acetate butyrate and cellulose acetate propionate. The binder has a melting point in the range of about 230.degree. C. to about 260.degree. C. An igniter (32) ignites the combustible material (20) to generate combustion products. A conduit directs the combustion products towards the air bag (4).
