摘要: A vehicular bumper system includes a tubular beam and an energy absorber press-fit within the beam. In particularly, front rear wall sections, planar stiffening sections that extend horizontally continuously completely between stabilizing sections. Pairs of stubby protrusions are formed on aligned with combine to define arrangement where, when is forcibly pressed into cavity beam, deformed stressed and/or shaved off such they friction-fit
