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.

Dual stage energy absorber

A bumper assembly () for an automotive vehicle is described. In an example embodiment, the assembly comprises a beam () and an injection molded energy absorber () secured to the beam. The energy absorber comprises at least one crash can (). The assembly further comprises a fascia () for covering the beam and the energy absorber.

Energy absorber with crash cans

An energy absorbing system for a vehicle includes an elongated energy absorber including a flanged frame for attachment to a reinforcing beam and a body including a plurality of spaced apart tunable crush boxes capable of deformation and progressive collapse upon impact for absorbing the energy of impact.
