摘要： 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.
