<p>PURPOSE: To inflate an inflatable vehicle occupant restraint system such as air bag at two different inflation speed. CONSTITUTION: An apparatus for use in inflating an air bag 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. 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. 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.</p> |
