description A thermoplastic energy absorber having a horizontal axis and a vertical axis comprises: an array of energy absorbing lobes protruding from a base, the lobes are arranged in two or more rows. The energy absorbing lobes can have a vertical length (L) and a horizontal width (D), and wherein a ratio of L and D is greater than 1. The energy absorbing lobes in each row can be disposed in a staggered manner with respect to energy absorbing lobes in an adjacent row. The energy absorber can be configured to be installed on a vehicle for absorption of impact energy. An energy absorbing system can comprise the thermoplastic energy absorber disposed between a bumper beam and a fascia. The fascia can optionally be configured to envelope the thermoplastic energy absorber and the bumper beam. This system passes EuroNCAP lower-leg impact requirements, version 5.1, June 2011, for lower leg impact requirement.
