Abstract
A bumper includes a bumper beam having a length and a primary front face forming an impact surface with at least one longitudinal channel formed therein. A rod is positioned in the channel and secured to the bumper beam, with the rod supporting side walls forming the channel. Upon impact, the rod supports the side walls of the channel from thin wall buckling. Thus, the material thickness of the beam can be decreased substantially (and concurrently a total weight decreased) while still maintaining a total force/deflection curve and optimal bending force of the beam.
