<p>The present invention provides an inflator 10 for an inflatable restraint system in an automobile. The inflator includes an elongate inflator body 11 having a plurality of inflation apertures 40 and defining a first combustion chamber 25 wherein a first propellant charge 28 is positioned. A partitioning assembly 26 is nested within the inflator body 11, and positioned proximate the second end 17. The partitioning assembly 26 defines a second combustion chamber 35 wherein a second propellant charge 38 is positioned. First and second initiators 12 and 9 are provided, and are selectively operable to ignite the propellant charges 28 and 38 respectively, thereby supplying an inflation gas via the first chamber 25 to an inflatable restraint cushion.</p> |
