PROBLEM TO BE SOLVED: To provide a lower limb protection air bag that has a simple configuration and is able to turn exactly backwards the end part of an end-side expansion part arranged at least on one-end side in a sideways direction when completely expanded.SOLUTION: A lower limb protective air bag 40 comprises: a body expansion part 42 that covers the front of a lower limb LB of a passenger D when expansion is completed; end-side expansion parts 49L, 49R; bending parts 51L, 51R arranged between the body expansion part 42 and the end-side expansion parts 49L, 49R, and configured to bend the end-side expansion parts 49L, 49R such that they project backward when expansion is completed; and connection means 58L, 58R that are able to maintain the bent states of the end-side expansion parts 49L, 49R when expansion is completed. The body expansion part 42 and the end-side expansion parts 49L, 49R are configured to expand into an approximately plate shape so as to separate a front-side wall part and a rear-side wall part. The bending parts 51L, 51R are composed of seam parts 52L, 52R coupled by superposing and joining the front-side wall part and rear-side wall part.SELECTED DRAWING: Figure 10

    【課題】簡便な構成として、膨張完了時に、左右方向の少なくとも一端側に配置される端側膨張部の端部を的確に後方に向けることが可能な下肢保護用エアバッグの提供。【解決手段】下肢保護用エアバッグ40は、膨張完了時に乗員Dの下肢LBの前方を覆う本体膨張部42と、端側膨張部49L,49Rと、本体膨張部42と端側膨張部49L,49Rとの間に配置されて膨張完了時に端側膨張部49L,49Rを後方へ突出させるように屈曲させる屈曲部51L,51Rと、膨張完了時の端側膨張部49L,49Rの屈曲状態を維持可能させる連結手段58L,58Rと、を備える。本体膨張部42と端側膨張部49L,49Rとが、表側壁部と裏側壁部とを離隔させるように略板状に膨張する構成とされる。屈曲部51L,51Rが、表側壁部と裏側壁部とを重ねて結合させたシーム部52L,52Rから、構成される。【選択図】図10
