摘要： A bumper system includes a rollformed tubular beam with bracket mounts welded to a rear surface for mounting to vehicle frame rails. The illustrated beam has a continuous tubular cross section for its entire length, and includes a center section, corner-forming end sections, and mounting sections connecting ends of the center section to the end sections. The center, end and mounting sections can be linear or similarly curved or differently curved. The center, end and mounting sections can be similarly or differently locally annealed as part of being tuned to specific impact loading criteria, including annealing all or part of cross-sectional areas. The annealing can be done in-line with a rollforming process, such as to assist with forming tight radii in the beam for meeting packaging/space-related requirements, or can be part of a secondary process for advantageously affecting impact strengths in selected localized areas.

摘要： An energy-absorbing crush tower for a vehicle bumper system includes a tube made of a continuous contiguous material, such as a heat-treatable steel. The tube has first and second ring sections connected by an interconnecting section. The first ring section is heat-treated to a high material strength, such as about 120 KSI tensile strength, which is substantially higher than the second ring section, which is kept at about 60 KSI tensile strength. The interconnecting section has a frustoconically-shaped portion forming a ramp. By this arrangement, upon the bumper system receiving an end impact parallel a length of the tube, the first and second ring sections telescopingly collapse with a predictable and consistent multi-phase deformation sequence where a third ring section forms between the first and second ring sections. A method related to the above is also disclosed and claimed.

摘要： A two-piece doorbeam including a relatively low-cost, low-strength body and a relatively high-cost, high-strength insert. The insert is hat-shaped and crimped within the body. The insert provides improved impact strength where needed, providing the doorbeam the desired strength at relatively low weight and low cost.

摘要： A bumper beam construction including an elongated tubular beam of high strength but characteristically flexible to absorb substantial energy on impact having a mounting bracket attached at each end of the center section and at least one stiffening bracket attached to each mounting bracket. The mounting brackets extend from the rear wall of the tubular beam and facilitate attachment to a vehicle frame. The stiffening brackets are attached to the mounting brackets and the end sections of the tubular beam outboard of the center section. The stiffening brackets improve the comer impact strength of the tubular beam without adversely affecting the flexibility of the center section. This comer construction arrangement provides for optimal distribution of stress during corner impacts.

摘要： A bumper beam includes an open front section made from a high-strength material such as ultra-high-strength steel (UHSS) material, and further includes a mating back section made of lower-strength material attached to a rear side of the front section along abutting flanges. The front and back sections combine to define different tubular cross sections. The front section can be roll-formed, and the back section can be stamped, thus taking advantage of roll-forming processes' ability to form high-strength materials, while allowing the back section to have a more complicated shape and be stamped. The abutting flanges telescopingly overlap in a fore-aft direction of the vehicle and are welded together at locations that potentially experience shear upon impact, but the flanges of the front section are captured within the flanges of the backs section, thus providing impact strength even if the attachment locations shear off.

摘要： An energy management structure includes an elongated polygonal tube with at least four walls, the tube having a larger first end and a smaller second end, at least two of the walls including a longitudinally-extending channel-shaped tapered rib starting at the smaller second end and extending toward the larger first end. The ribs become shallower near the larger first end. The walls include crush initiators so that the ribs do not provide undesired strength to the tube during a longitudinal impact. A related method includes roll-forming a polygonal tubular shape with at least four walls, at least two of the walls including longitudinally-extending channel-shaped ribs, and reforming the tubular shape into a tapered polygonal shape with a larger end and a smaller end, the ribs becoming shallower as the ribs extend closer to the larger end.

摘要： A bumper construction for vehicles includes an elongated high-strength metal beam roll-formed from sheet steel, and at least one structural molded piece made of polymeric material attached to opposing end sections of the beam. Each structural piece has a rearwardly swept front surface that forms aerodynamically stylized corners at the ends of the beam. Each structural piece further provides attachment structure for attaching the beam to a vehicle, with the attachment structure being configured to transmit front impact forces compressively through the structural pieces to the vehicle frame, while minimizing the torsional and tensile forces on the attachment structure. The structural pieces further include a recess for closely receiving and supporting an impact-resisting flange on the beam to stabilize the beam during impact. The mateable engagement simplifies assembly, and further provides for high-energy absorption upon front impact of a vehicle.

摘要： A platform system includes swing arms for moving the platform from a lowered position to a raised position. In one embodiment, a pair of swing arms and a pair of telescoping vertical members are mounted to opposing frame members. The swing arms are capable of moving from a canted position to a vertical position, which extends the telescoping vertical members and raises the platform to the raised position. The swing arms are connected to a drive mechanism that moves the swing arms from the canted position to the vertical position. The drive mechanism may include a gear box, and a pair of lead screws connected to the gear box. The lead screws may extend from opposing sides of the same gear box, with the gear box configured to rotate the differently handed lead screws.
