Inflator
First Claim
1. An inflator comprising:
- a combustion chamber;
an ignition device located inside the combustion chamber;
a first gas generating charge filled in the combustion chamber for combustion, by ignition of the ignition device, to generate an inflation gas;
a second gas generating charge filled in the combustion chamber at a location away from an ignition area of the ignition device, with the first gas generating charge interposed between itself and the ignition area, the second gas generating charge being slower in speed of combustion than the first gas generating charge and ignitable by a flame generated by combustion of the first gas generating charge; and
a partition wall that segregates the first gas generating charge and second gas generating charge inside the combustion chamber so as to prevent the first and second charges from mixing, the partition wall being burnable to destruction by a fire built by combustion of the first gas generating charge so as to allow the fire to propagate to the second gas generating charge over a generally entire area that the partition wall bounds the first and second gas generating charges.

Abstract
An inflator includes in a combustion chamber a first gas generating charge and a second gas generating charge to be ignited and burned to generate an inflation gas. The second gas generating charge is slower in speed of combustion than the first gas generating charge. The inflator further includes a partition wall that segregates the first and second gas generating charges. The partition wall is located away from an ignition area of an ignition device that ignites the first gas generating charge, with the first gas generating charge located between itself and the ignition area. The partition wall is burnable to destruction by the fire generated by combustion of the first gas generating charge so as to permit propagation of the fire to the second gas generating charge by its generally entire area.
