PROBLEM TO BE SOLVED: To suppress a re-increase of a head of a pedestrian of latter collision, and protect the head of the pedestrian.SOLUTION: A front panel 10 is provided with a resin panel 11 on a surface side and an elastic sheet 12 on a rear side. The resin panel 11 is a plate-like member formed of a resin material having comparatively low toughness. The elastic sheet 12 is an elastic sheet 12 formed of a material which has lower rigidity than that of the resin panel 11 and has very large breaking elongation, is overlapped in layers on a rear face 11a of the resin panel 11, and is bonded and fixed to the resin panel 11. When the vehicle 1 collides with the pedestrian, an initial peak of acceleration of the head of the pedestrian by the resin panel 11 occurs immediately after the collision, the resin panel 11 is broken, the acceleration of the head of the pedestrian is lowered, and then the energy of the head is absorbed by the elastic sheet 12 with low acceleration.SELECTED DRAWING: Figure 2
【課題】衝突後半の歩行者の頭部の加速度の再度の上昇を抑制して、歩行者の頭部を保護する。【解決手段】フロントパネル10は、表面側の樹脂パネル11と、裏面側の弾性シート12とを備える。樹脂パネル11は、比較的靭性の低い樹脂材料で形成された板状部材である。弾性シート12は、樹脂パネル11よりも剛性が低く、非常に破断伸びが大きい材料で形成された弾性シート12であって、樹脂パネル11の後面11aに層状に重ねられ、樹脂パネル11に対して接着されて固定される。車両1と歩行者とが衝突した際、樹脂パネル11によって歩行者の頭部の加速度の初期ピークを衝突直後に発生させて、樹脂パネル11が破断して歩行者の頭部の加速度が低下した後、弾性シート12によって低い加速度で頭部のエネルギーを吸収する。【選択図】図2
