PROBLEM TO BE SOLVED: To provide a pedestrian airbag device capable of quickly and accurately completing expansion of an airbag covering the upper surface of a front pillar.SOLUTION: An airbag 60 of the pedestrian airbag device includes a horizontal expansion part 66 for covering the cowl 7 of the rear part of a hood panel 10 of a vehicle, and vertical expansion parts 72 for covering left and right front pillars 5. The horizontal expansion part includes a hood side expansion part 67 disposed in a region below the rear end 10c of the hood panel, and an exposed side expansion part 70 exposed from the hood panel to communicate with the left and right vertical expansion parts. A partition tether 74 is installed to partition an expansion portion from the exposed side expansion part to the left and right vertical expansion parts into a secondary expansion part 82 along the rear edge 60 of the airbag and a front side primary expansion part 81, and support ports 80 are arranged only near both ends 74a and 74n to enable supplying of expansion gas from the primary expansion part side to the secondary expansion part side.SELECTED DRAWING: Figure 16

    【課題】展開膨張時のエアバッグが迅速かつ的確にフロントピラーの上面を覆って膨張を完了させることができる歩行者用エアバッグ装置を提供すること。【解決手段】歩行者用エアバッグ装置のエアバッグ60が、車両のフードパネル10の後方のカウル7を覆う横膨張部66と左右のフロントピラー5を覆う縦膨張72とを備える。横膨張部は、フードパネルの後端10cの下方領域に配置されるフード側膨張部67と、フードパネルから露出して、左右の端部付近で、左右の縦膨張部に連通する露出側膨張部70と、を備える。区画テザー74が、露出側膨張部から左右の縦膨張部までの膨張部位を、エアバッグの後縁60に沿う二次膨張部82と前側の一次膨張部81とに区画するように、配設されるとともに、両端部74a,74b付近だけに、一次膨張部側から二次膨張部側へ膨張用ガスを供給可能な供給口80、を設けて配設される。【選択図】図16
