ABSTRACT:
The present invention provides a manufacturing method for an air bag which can simply form an inner bag inside a outer bag. Cloth members of the inner bag are mounted within the outer bag and the outer bag is sewn together along its peripheries except its folded portion and a gas inlet hole for introducing gas from an inflator, by using threads. Thereafter the cloth members of the inner bag are put into the outer bag, and the cloth members of the inner bag are pulled out of the outer bag through the gas inlet hole. Thereafter, the cloth members of the inner bag are sewn together along their peripheries by using a thread. Thus, the cloth members of the inner bag are formed into a bag. Finally, putting the inner bag into the outer bag makes the air bag completed.
