Abstract
A motor vehicle bumper that has enhanced energy absorption characteristics and that includes one or more unique geometry configurations that extend 'softer' energy absorbing surfaces forward in the system while nesting more 'rigid' energy absorbing surfaces more rearward only to come into effect when higher energy impacts are observed. The dual energy absorption may be achieved using a number of configurations and/or methods or a combination of several. In one or more embodiments, the wall thickness of the material used in the component or components may be varied, materials having different stiffness properties may be used, and/or geometries of different depth and section stiffness may be alternated across the bumper system.
