To provide an air bag device which suppresses damage of a pedestrian or the like and can mitigate damage of a vehicle when colliding with an obstacle.SOLUTION: An air bag device comprises: an air bag 30 which is developed from a vehicle body front part of a vehicle 1 to a front side; a collision determination part 120 which establishes, when collision possibility with a human body P or an obstacle is a prescribed threshold value or more, a pre-crash determination; and an air bag development control part 110 which develops the air bag according to the pre-crash determination. The air bag comprises: a slit part 34 which is formed by recessing a front face part 31 into the vehicle rear side so that a front part of the air bag is branched; a plurality of branch parts 35 which are branched by the slit part; a connection member 40 which connects the branch parts by the slit part with each other at the front part of the air bag; and a connection member nullification part 113 which nullifies, when collision with a human body is predicted, the connection of the branch parts by the connection member.SELECTED DRAWING: Figure 4
【課題】歩行者等の被害を抑制しかつ物体との衝突時における車両の被害を軽減可能なエアバッグ装置を提供する。【解決手段】車両１の車体前部から前方側へ展開するエアバッグ３０と、人体Ｐ又は物体との衝突可能性が所定の閾値以上である場合にプリクラッシュ判定を成立させる衝突判定部１２０と、プリクラッシュ判定に応じてエアバッグを展開させるエアバッグ展開制御部１１０とを備えるエアバッグ装置を、エアバッグは、前面部３１を車両後方側に凹ませて形成されエアバッグの前部を分岐させるスリット部３４と、スリット部によって分岐された複数の分岐部３５とを有し、エアバッグ装置はさらにエアバッグの前部におけるスリット部により分岐された部分を相互に連結する連結部材４０と、人体との衝突が予測される場合に連結部材による分岐部の連結を無効化する連結部材無効化部１１３とを備える構成とする。【選択図】図４
