PROBLEM TO BE SOLVED: To obtain a mounting structure of a pedestrian protection airbag device for a vehicle attached to a hood which can stabilize a deployment behavior of a hood airbag while securing a degree of freedom of a design layout of the hood.SOLUTION: A pedestrian protection airbag device 28 for a vehicle is arranged at a vehicle rear side of a swelling part 70 arranged at a hood 14, and a rear end wall 72B and a hood hinge attachment part 76 are arranged at the swelling part 70. Therefore, a deployment reaction force of an airbag 32 is supported by the rear end wall 72B, and the deployment reaction force is transmitted to the hood hinge attachment part 76 from the swelling part 70. As a result, the deployment reaction force when the air bag 32 is swollen and deployed is transmitted to a hood hinge 24, and also transmitted to a vehicle body 15. Accordingly, the airbag 32 can be deployed without installing an airbag door or the like to the hood 14, and a stress concentration to the surroundings of the hood hinge attachment part 76 can be suppressed.
【課題】フードの意匠設計の自由度を確保しつつ、フードエアバッグの展開挙動を安定させることができるフード付け車両用歩行者保護エアバッグ装置の搭載構造を得る。【解決手段】フード14に設けられた膨出部70の車両後方側には、車両用歩行者保護エアバッグ装置28が配設されており、膨出部70には、後端壁72B及びフードヒンジ取付部76が設けられている。このため、エアバッグ32の展開反力が後端壁72Bによって支持され、当該展開反力が膨出部70からフードヒンジ取付部76に伝達される。その結果、エアバッグ32が膨張展開したときの展開反力がフードヒンジ24に伝達され、ひいては車体15に伝達される。従って、フード14にエアバッグドア等を設けることなくエアバッグ32を展開させることができると共に、フードヒンジ取付部76の周辺部に応力が集中することを抑制することができる。【選択図】図1
