PROBLEM TO BE SOLVED: To provide an air bag that improves a shock absorbing characteristics while inflating and expanding along a shape of the head of an occupant.SOLUTION: An air bag main body part 11 comprises a plurality of second inflating parts 25 extending radially along a prescribed direction. Each inflating part 25 is formed so that an edge part thereof along an extending direction bends in a wave shape. Edge parts of the second inflating parts 25 and 25 adjacent to each other form complementary shapes. The edge parts of the second inflating parts 25 and 25 adjacent to each other are connected integrally to each other. The air bag main body part 11 can be inflated and expanded along the shape of the head A of an occupant. Bottoming between the second inflating parts 25 and 25 is inhibited and thereby a shock absorbing stroke is secured, so that shock absorbing characteristics can be improved.SELECTED DRAWING: Figure 1
【課題】乗員の頭部の形状に沿って膨張展開しつつ、衝撃吸収特性を向上したエアバッグを提供する。【解決手段】エアバッグ本体部11は、所定方向に沿って放射状に延びる複数の第2の膨張部25を備える。各第2の膨張部25を、延びる方向に沿う縁部が波状に屈曲するように形成する。互いに隣り合う第2の膨張部25,25の縁部同士が相補的な形状をなす。互いに隣り合う第2の膨張部25,25の縁部を一体に接合する。エアバッグ本体部11を乗員の頭部Aの形状に沿って膨張展開させることができる。第2の膨張部25,25間の位置での底付きを抑制し、衝撃吸収ストロークを確保することで衝撃吸収特性を向上できる。【選択図】図1
