車両衝突時にあっては、衝突エネルギーによりフエイシャが変形して衝突エネ ルギー吸収体も圧縮して衝突エネルギーが吸収されるが、この場合、衝突エネル ギー吸収体は前後方向に圧縮するとともに、その山形後端部がアーマチャーの擂 鉢状陥凹部に係合しその上下面が斜面係合しているため、上下方向にも圧縮され 、効率良く体積収縮が進行し、衝突エネルギーの吸収が効率良く行なわれる。 In the event of a vehicle collision, the fascia deforms due to the impact energy and absorbs the impact energy. The collision energy is also absorbed by compressing the energy absorber, but in this case, the collision energy The energy absorber compresses in the front and back direction, and its chevron-shaped rear end is bent by the armature. Because it engages with the bowl-shaped recess and its upper and lower surfaces engage on slopes, it is also compressed in the vertical direction. , volumetric contraction progresses efficiently, and collision energy is efficiently absorbed.
