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).
1. An apparatus for use in inflating a vehicle occupant protection device, the apparatus comprising:a container; a combustible material stored in the container, the combustible material comprising a first binder selected from the group consisting of cellulose acetate butyrate having a butyryl content of less than about 30% by weight based on the weight of the cellulose acetate butyrate, and cellulose acetate propionate having a propionyl content of more than about 30% by weight based on the weight of the cellulose acetate propionate, wherein the first bi...
