하나의 실시형태에서, 다단계 에너지 흡수 시스템은 열가소성 플랜지를 가진 프레임 및 플랜지를 가진 프레임과 정렬되는 근위 베이스 및 플랜지를 가진 프레임으로부터 돌출되는 원위 단부를 가지는 크러시 로브를 포함한다. 크러시 로브는 총 2i + 1 개의 슬래브를 포함하도록, 여기서 i는 슬래브 쌍의 개수로서, 1 이상이 되도록, 중심 슬래브 및 슬래브 쌍을 포함한다. 슬래브는 계단형 배열로 배치되고, 증가되는 에너지 레벨을 갖는 텔레스코프 방식으로 붕괴됨으로써 충격 에너지를 흡수하도록 구성된다.

    In an embodiment, multi-stage energy absorbing system can comprise: a thermoplastic flanged frame and a crush lobe having a proximal base aligned with the flanged frame and a distal end protruding from the flanged frame. The crush lobe comprises a central slab and slab pairs such that the crush lobe comprises a total of 2i+1 slabs, wherein i is the number of slab pairs and is greater than or equal to 1. The slabs are disposed in a stepped arrangement and configured to absorb impact energy by collapsing in a telescopic manner with increasing energy level. The single energy-absorbing system is able to absorb low energy impact associated with vehicle-to-pedestrian impact; simultaneously with the ability to mitigate damageability associated with low-speed vehicle-to-barrier impact, as well as damageability associated with vehicle-to-vehicle moderate speed impact, head-on, as well as at an angle.
