<p>A vehicular bumper system (10) includes a tubular beam (11) and an energy absorber (12) press-fit within the tubular beam. In particularly, the energy absorber includes front and rear wall sections (25-26), planar stiffening wall sections (15-19) that extend horizontally continuously and completely between the front and rear wall sections, and stabilizing wall sections that extend between the planar stiffening wall sections. Pairs of stubby protrusions (13,13') are formed on the rear wall sections that are aligned with the planar stiffening wall sections and that combine with the front and rear wall sections to define an arrangement where, when the energy absorber is forcibly pressed into the cavity of the tubular beam, the protrusions are deformed and stressed and/or shaved off such that they friction-fit into the tubular beam.</p> |
