An air bag body (1) is expanded by charging an air therein after being expanded in a flat surface shape. Next, by gently gripping the air bag body (1) by upper and lower blades (26, 25) radially arranged in a radial direction of the air bag body (1), a height in a radial direction of the air bag body (1) is linearly restricted along the upper and lower blades (26, 25). Next, a plurality of movable blocks (24) are forward moved toward a center of the air bag body (1), and upper and lower panels (12, 11) of the air bag body (1) are accumulated. At this time, the upper and lower panels (12, 11) of the air bag body (1) are folded in a state of being apart from each other so as to form a wave shape. Next, the air bag body (1) is rotated, a portion left in a tab shape is wound around a periphery, and a center protruding portion of the air bag body (1) is pressed from an upper side, whereby a front surface deploying portion (35) is formed. When supplying gas to the folded air bag body (1), the front surface deploying portion (35) rapidly deploys so as to break a cover (5) and the gas is smoothly supplied to a peripheral edge portion (14), whereby it is possible to smoothly and rapidly deploy the air bag body (1).
A method of folding an air bag body having a first surface portion with an inlet port through which gas is introduced into the air bag body and a second surface portion opposing to the first surface portion, the method comprising the steps of:
