  • Patent number: 6874832
    Abstract: A bumper includes a beam and an energy absorber supported thereon. The energy absorber includes horizontal walls, each having a front portion, a rear portion, and an interconnecting mid-portion that offsets and misaligns the front and rear portions. Upon impact, the front and rear portions collapse with the offset mid portion wrapping back upon itself with a predictable energy-absorbing collapse. The energy absorber further includes flanges and friction pads that frictionally engage the top and bottom of the beam to temporarily retain the energy absorber to the beam. In one embodiment, the front beam wall includes at least one aperture, and the energy absorber includes a tubular column extending from its front wall through the aperture in the front beam wall to the rear beam wall. By this arrangement, the front wall of the energy absorber receives support from the front beam wall via the structural column.

  • Patent number: 6848730
    Abstract: A bumper system includes a tubular beam having front and rear walls, and a plurality of horizontally-extending walls that interconnect the front and rear walls. An energy absorber has a rear surface with a recess shaped to mateably receive and support the beam, and includes end sections that extend to be coplanar with the rear wall of the beam. The end sections cover the front wall and also at least partially cover a top, bottom and ends of the beam, and are constructed to flex and absorb energy to reduce a likelihood of vehicle damage. In one form, the end sections include honeycomb sections that engage beam mounts to transfer impact energy directly to the mounts. In another form, the end sections include cantilevered flanges that extend outwardly from ends of the energy absorber for impact absorption at the vehicle corners.

  • Publication number: 20050017520
    Abstract: An integrated one-piece polymeric molded component includes an energy-absorbing section, a fascia-supporting beam section, and a plurality of connecting section connecting the energy-absorbing and fascia-supporting beam sections. The energy-absorbing section engages a front of a bumper beam and includes crush boxes configured to absorb impact energy during a vehicle crash. The connecting sections are strong enough to hold the energy-absorbing section and the fascia-supporting beam section together during assembly of the one-piece component onto a vehicle, but are flexible to allow collapse of the energy-absorbing section during a vehicle crash without damaging the fascia-supporting beam section. The beam section is channel-shaped and extends cross-car generally between headlamps of the vehicle, for providing added support structure to a front-end of the vehicle. The beam section includes air-redirecting ridges for optimal air flow and integral clips for wire management.

  • Publication number: 20040256867
    Abstract: A bumper system includes a “W” or “C” shaped beam having a back wall and mounts along the back wall adapted for attaching the beam to rails of a vehicle frame. An energy absorber engages a face of the beam and has rearwardly-extending energy-absorbing sections that extend through the face into contact with the back wall at each of the mounts for improved energy absorption. The horizontal walls of the beam have front and rear sections that align, but also have a U-shaped intermediate section that weakens the walls for promoting a more uniform and predictable collapse. A one-piece brace includes diagonal straps that hold free ends of top and bottom walls together to prevent premature spreading apart upon impact. The energy absorber includes energy-absorbing sections that extend past the straps to detentingly engage the intermediate sections of the beam.

  • Publication number: 20040119301
    Abstract: A vehicle bumper system includes a beam, and an energy absorber with top and bottom horizontal sections and a mid-horizontal section. The horizontal sections form top and bottom nose portions that are semi-rigid but initially collapsible with a parallelogram motion that shifts the top and bottom portions vertically up (or down) upon-impact. Horizontal impact forces are converted in part to vertical forces during an initial stroke of a frontal impact, “catching” an impacted human being. Then during a further continuing impact stroke, the top and bottom horizontal sections provide a “throwing” action. End sections of the energy absorber extend around ends of a bumper beam, forming a collapsible corner that, during impact, initially absorbs energy at a low rate to “catch” a person, and then develops increasing lateral forces that “throw” the person during a continuing impact stroke.

  • Patent number: 6746061
    Abstract: A vehicular bumper system includes a tubular beam and an energy absorber press-fit within the tubular beam. In particularly, the energy absorber includes front and rear wall sections, planar stiffening wall sections that extend horizontally continuously and completely between the front and rear wall sections, and stabilizing wall sections that extend between the planar stiffening wall sections. Pairs of stubby protrusions are formed on the rear wall sections that are aligned with the planar stiffening wall sections and that combine with the front and rear wall sections to define an arrangement where, when the energy absorber is forcibly pressed into the cavity of the tubular beam, the protrusions are deformed and stressed and/or are shaved off such that they friction-fit into the tubular beam.

  • Publication number: 20040084911
    Abstract: A bumper system includes a bumper beam having a face and ends, and an energy absorber mounted on the face. The energy absorber has a one-piece injection-molded non-foam piece with box sections and interconnecting straps, and a one-piece or multi-piece foam component securely insert-molded onto the injection-molded non-foam piece. Different foam molds can be used to form differently shaped front surfaces on the foam component. By this arrangement, different energy absorbing systems are provided for vehicles, such as to satisfy the need for different styling and shapes, while still using the same non-foam piece. By this arrangement, the energy absorber is a single unit that can be handled and attached to the bumper beam. At the same time, capital investment in molding dies and tooling is reduced.
