To provide a pedestrian protection device which can eliminate the possibility that a pedestrian fallen over a front hood falls on a ground surface.SOLUTION: When a vehicle contacts with a pedestrian, an airbag body 11 is inflated and deployed onto a front pillar 14 and a front end part of a front window 7 and a rear end part of a front hood 6 is lifted up by a lift mechanism 13. Transmission chambers 19 are provided at left and right sides of a front edge of the airbag body 11 and are inflated on the rear end part of the front hood 6 by gas supplied through the airbag body 11. Upward position displacement of the rear end part of the front hood 6 is transmitted to the airbag body 11 through the transmission chambers 19 to deform the left and right sides to shapes curved upward. The action prevents movement of a head and a chest part of the pedestrian on the airbag body 11 to the left and right sides to hold the pedestrian on the front hood 6.SELECTED DRAWING: Figure 3

    【課題】フロントフード上に倒れ込んだ歩行者が地面に落ちる可能性を解消できる歩行者保護装置を提供する。【解決手段】歩行者との接触時に、フロントピラー14上及びフロントウインド7の前端部上にエアバッグ袋体11を膨張展開させると共に、リフト機構13によりフロントフード6の後端部をリフトアップさせる。エアバッグ袋体11の前縁の左右両側に伝達チャンバ19を設け、エアバッグ袋体11を経て供給されるガスによりフロントフード6の後端部上で膨張させる。伝達チャンバ19を介してフロントフード6の後端部の上方への位置変位をエアバッグ袋体11に伝達し、左右両側を上方に湾曲させた形状に変形させる。これにより、エアバッグ袋体11上の歩行者の頭部や胸部の左右側方への移動を妨げてフロントフード6上に歩行者をとどめる。【選択図】図3
