ENERGY ABSORBER WITH LOBES PROVIDING UNIFORM PEDESTRIAN IMPACT |
摘要 |
<p>A bumper system includes an injection molded energy absorber of polymeric material having hollow longitudinally-spaced lobes configured to crush and absorb energy during a pedestrian impact, and straps interconnecting adjacent lobes. The lobes are particularly sized and dimensioned, including potentially external ribs and/or apertures in corners, to provide a relatively uniform impact energy absorption during an impact stroke during crush of the shear walls of the lobes, such as within +/−30% or more preferably within +/−20% of a desired amount regardless of a specific location of impact, along a selected center portion of the energy absorber. A reason for the uniformity is to promote pedestrian safety regardless of the specific location where a pedestrian's leg strikes the energy absorber.</p> |
