Abstract
An apparatus (10) for use in inflating an air bag (12) includes an ignitable body (110) of gas generating material and an igniter (206). The body (110) of gas generating material, when ignited, generates gas for inflating the air bag (12). The body (110) of gas generating material has an outer surface area (132). The igniter (206) contains a first output charge (230) and a second output charge (232). When the first and second output charges (230) and (232) are ignited sequentially, the body (110) of gas generating material is ignited at a first ignitable surface area including the outer surface area (132). When the first and second output charges (230 and 232) are ignited simultaneously, the body (110) of gas generating material is ignited at a second ignitable surface area in addition to the first ignitable surface area.
