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.

Abstract: A bumper system for an automobile vehicle includes, in an exemplary embodiment, a beam and an energy absorber coupled to the beam. The beam has a top surface and a bottom surface, and is configured to attach to the vehicle. The energy absorber includes a body having a first side and an opposing second side, a plurality of crush lobes extending from the first side, and a plurality of vertical translational crush lobes extending from the second side. The second side faces the beam, and each vertical translational crush lobe engages the top surface or the bottom surface of the beam.

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 includes a body, an upper crushable member extending from the body, and a lower crushable member extending from the body and spaced apart from the upper crushable member. The upper and lower crushable members each include an upper transverse wall, a lower transverse wall, and an outer wall. Each upper transverse wall and each lower transverse wall includes alternating solid portions and open portions. Each solid and open portion extends from the body to the outer wall of a crushable member. The solid portions of the lower transverse wall of the upper crushable member are aligned with the open portions of the upper transverse wall of the lower crushable member.

Abstract: A bumper system for an automobile vehicle includes, in an exemplary embodiment, a first beam configured to attached to the vehicle and a first energy absorber coupled to the first beam. The first energy absorber is tunable for meeting predetermined criteria for both low speed and pedestrian impacts, and includes a plurality of tunable lobes. The lobes are tuned so that a stiffness of the first energy absorber varies from a center of the first energy absorber to each end.

Abstract: A bumper system for an automobile vehicle includes a beam configured to attached to vehicle rails 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 flanged frame for attachment to the beam, a body that includes a plurality of lobes extending from the flanged frame and spaced apart from each other. Each lobe includes first and second side walls, having a concave shape.

Abstract: A hybrid bumper system includes a hollow reinforcing metallic beam and a molded engineering thermoplastic resin energy absorber. The energy absorber further includes at least one crushable portion. The hollow metallic beam is secured in a physically stable combination with the energy absorber, thereby resulting in a solitary hybrid bumper system.
