ABSTRACT:
An air bag is unfolded on a planar surface and is inflated with air. The air bag is loosely sandwiched between the upper and lower blades that are arranged in a radial configuration. Movable blocks progress toward the center to fold the upper and lower panels of the air bag against the central part of the air bag. The resulting central folded part of the air bag has a wave-like configuration, and the upper and lower panels are separated from each other. The ear-like portions of the air bag are wound around the central folded part of the air bag that is folded in a wave-like configuration. Then, the central part of the air bag is pressed downward to complete the folding process. Gas can be supplied smoothly from the inlet port to the periphery when the air bag is reinflated. The method for folding the air bag is simple, and the air bag can be inflated quickly.
