The present invention relates to an automotive bonnet comprising: an outer panel; and an inner panel coupled to one surface of the outer panel. The inner panel includes: a frame having an opening formed at the center thereof and coupled to one surface of the outer panel; and a framework unit formed in a lattice shape in the frame unit in which the opening is formed to form a plurality of cells. The frame unit is formed so that both sides of a corner are curved downward in the outward direction. According to the present invention, collision energy due to second collision of a pedestrian is dispersed through structural modification of the inner panel, and absorbed through a deformation behavior to attenuate the collision energy. Therefore, shock which repulsively returns to the pedestrian is reduced, and protection performance of the pedestrian can be remarkably improved.

    본 발명은 외패널과, 상기 외패널의 일면에 결합되는 내패널을 포함하는 차량용 보닛에 관한 것으로서, 상기 내패널은 중앙에 개구가 형성되고, 상기 외패널의 일면에 결합되는 프레임 및 상기 개구가 형성된 상기 프레임부 내에 격자 형상으로 형성되어 다수의 셀(cell)을 형성하는 골조부를 포함하되, 상기 골조부는 모서리 양측이 외측 방향으로 하향 만곡지게 형성되는 것을 특징으로 한다. 상기와 같은 본 발명에 의하면, 내패널의 구조변경을 통해 보행자의 2차 충돌에 따른 충돌 에너지를 분산시켜 변형 거동을 통해 흡수하여 이를 감쇠시킴에 따라 보행자에게 반발적으로 되돌아가는 충격이 감소되어 보행자의 보호성능을 현저하게 향상시킬 수 있는 효과가 있다.
