Abstract
A method of manufacturing an airbag with which an airbag having a left airbag section and a right airbag section and constituted so that peripheral edge portions of an opening of an opposing face of each bag are sewn together can be easily manufactured. An airbagis constituted by a total of two panels, namely, an inside paneland an outside panel. After the inside paneland the outside panelare overlapped in a double-folded state so that airbag outer side faces thereof oppose to each other, opposite sidesare sewn together, and lower edge portions of the inside paneland the outside panelare sewn together. Then, the inside panelis reversed so that airbag outer side faces of a right sideR and a left sideL oppose each other, and the peripheral edge portions of the openingsare sewn together. Then, the remaining peripheral edge portions of the inside paneland the outside panelare sewn together. Then, the outside panelis reversed through an opening port M on rear end sides of the inside paneland the outside panel, and the opening port M is sealed.
