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.
