Abstract:
A bumper system for a vehicle comprising a stamped metal component and a second polymeric component fixedly attached to form a beam with particular localized energy absorber characteristics. The metal component is formed from a sheet and has a thickness in a width direction along a majority of the length when in a vehicle-mounted position. The second polymeric component engages a face of the first component and is rigidly attached to the first component in at least several locations along the length to form a structural beam with the first component. The second polymeric component has sufficient structure to form an integral part of the structural beam and interconnected walls extending in the width direction to form energy-absorbing cells at centered and corner locations configured to crush and absorb energy upon a vehicle impact.
Abstract:
Ce système (1) d'absorption d'énergie est adapté pour un véhicule automobile muni de longerons (2). Le système (1) comporte une poutre supérieure d'absorption (3), destinée à être agencée devant les longerons (2) du véhicule automobile, une poutre inférieure d'absorption (4), destinée à être agencée en dessous de la poutre supérieure d'absorption (3), et au moins deux jambages (5) assurant une liaison rigide entre les poutres supérieure (3) et inférieure (4). Il comporte en outre une traverse rigide (6) s'étendant entre les longerons (2) et étant directement fixée sur ces longerons (2), la poutre supérieure (3) étant fixée en appui contre cette traverse (6).
Abstract:
The invention relates to an arrangement for a motor vehicle shock absorber, in which at least one shock-absorbing element (14) is disposed between the skin of the face bar (10) and a structural cross-member (12) with a clearance (J) for mounting operations being provided between the shock-absorbing element (14) and the cross-member (12). The invention is characterised in that a play-adjustment means (18), which is supported by a wall (16) of the shock-absorbing element (14), is disposed between the shock-absorbing element (14) and the cross-member (12), such as to limit the deformation of the face bar skin (10) when the latter is subjected to a moderate force, while enabling mounting operations to be performed.

Abstract:
A process for in-molding an energy-absorbing countermeasure to a headliner 18 for use in a vehicle, plus the intermediate and final assemblies formed by the process. The process includes the steps of (1) preparing a sheet; (1A) optionally affixing to the sheet a means for adhering to form a composite sheet; (2) thermoforming the composite sheet into a composite energy-absorbing countermeasure; (3) preparing a headliner layup (including optionally a means for adhering, a headliner core, and a cover stock) before forming a bond between the headliner layup and the composite energy-absorbing countermeasure. The assembly thus includes the energy-absorbing countermeasure 22 and a means for adhering it to the headliner core 18.
Abstract:
A bumper beam energy absorbing system (10) is disclosed for absorbing impact energy exerted on an automotive vehicle. The energy absorbing system (10) includes a rigid, structural impact beam (12), a decorative fascia (16),and an energy absorber (14) sandwiched between the impact beam (12) and fascia (16). The impact beam (12) is adapted to attach the energy absorber to the vehicle while the fascia (16) decoratively covers and conceals the energy absorber (14). The energy absorber (14) is comprised of layers of cell panels (20). Each cell panel (20) is extruded into an open cell network in which interconnected closed loop cell walls define a plurality of open cells, thereby creating the network. The cross-section of the cells (22, 22’) in one cell panel may differ to adjust the amount of energy absorbed by a particular section of the panel. Likewise, the overall open cell network may vary between the layers, thereby adjusting the amount of energy absorbed by each particular layer.
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.
Abstract:
A hybrid bumper system (10) includes a hollow reinforcing metallic beam (12) and a molded engineering thermoplastic resin energy absorber (14). The energy absorber (14) further includes at least one crushable portion (15,17). The hollow metallic beam is secured in a physically stable combination with the energy absorber, thereby resulting in a solitary hybrid bumper system.
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 multipiece foam component securely insert-molded onto the injection-molded non-foam piece. Different foam 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.
