1. A method of manufacturing a bag for an air bag system, said method comprising the steps of:
- (a) securing together a first base cloth having a gas inlet and a second base cloth along a periphery thereof after stacking said first base cloth and said second base cloth so that said periphery has a first rupture strength;
(b) forming a main bag and at least one auxiliary bag immediately after securing together said first base cloth and said second base close along the periphery thereof so that said at least one auxiliary bag is located between said main bag and said periphery and a division between said main bag and said auxiliary bag has a second rupture strength which is less than said first rupture strength; and
(c) turning the first base cloth and the second base cloth inside out via the gas inlet after forming said main bag and at least one auxiliary bag so that said at least one auxiliary bag can be located interiorly of said main bag.
