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.

Abstract: A bumper system for an automobile vehicle includes, in an exemplary embodiment, a beam configured to attach to the vehicle, and a thermoplastic energy absorber coupled to the beam. The energy absorber includes an upper portion including a frame portion and a body having a plurality of tunable crush lobes extending from the frame portion. The energy absorber also includes an underbar spaced apart from the upper portion and a plurality of connecting towers extending between the upper portion and the underbar and connecting the underbar to the upper portion.

Abstract: A bumper system for an automobile vehicle includes, in an exemplary embodiment, a beam configured to attach to the vehicle, and an energy absorber coupled to the beam. The energy absorber is tunable for meeting predetermined criteria for both low speed and pedestrian impacts and includes a frame portion and a body including a plurality of tunable crush lobes extending from the frame portion. Each crush lobe is longitudinally spaced apart from an adjacent crush lobe, and at least one crush lobe includes a first transverse wall, a second transverse wall spaced apart from the first transverse wall, a third transverse wall spaced apart from the second transverse wall, and a front wall coupled to the first and second transverse walls. The first, second, and third transverse walls extend from the frame portion and the second transverse wall is located between the first and third transverse walls.
