To provide a pedestrian protection device capable of protecting a pedestrian in a primary collision and a secondary collision in a vehicle collision by reliably separating an air bag from a vehicle in a short time while putting it to the pedestrian, and maintaining pressure in the air bag after the separation at a constant level.SOLUTION: A pedestrian protection device includes an air bag 4 inflated and deployed by gas from an inflator 6, a communication part 8, and a one-way valve 7. The air bag can be held while being put to a pedestrian. The communication part communicates the air bag and the inflator with each other, and separates them. The one-way valve causes gas to flow into the air bag, and prevents back flow of the gas that has flowed into the air bag.SELECTED DRAWING: Figure 1

    【課題】車両衝突に際し、歩行者に付着させつつエアバッグを車両から短時間で確実に分離させると共に、分離後のエアバッグ内の圧力を一定に維持させることで、1次衝突並びに2次衝突における歩行者の保護を図る歩行者保護装置を提供する。【解決手段】インフレータ6からのガスで膨張展開するエアバッグ4と、連通部8と、一方向バルブ7と、を有する。エアバッグは、歩行者に付着しつつ保持可能である。連通部は、エアバッグとインフレータとの間を連通させると共に分離させる。一方向バルブは、ガスをエアバッグ内に流入させると共に、エアバッグ内に流入されたガスの逆流を防止する。【選択図】図1
