摘要： An energy management system comprising a longitudinally extending beam including a first beam portion and a second beam portion. A first one of the first beam portion and the second beam portion has a first face, a first side wall and a second side wall. A second one of the first beam portion and the second beam portion has a second face. The first side wall has a first U-shaped section spaced from the first face and the second side wall has a second U-shaped section spaced from the first face. The first side wall rolls to enlarge the first U-shaped section and the second side wall rolls to enlarge the second U-shaped section during an impact force directed against the first face of the first beam portion or the second face of the second beam portion.

摘要： An energy-absorbing system includes a tube made of a continuous polymeric material. The tube has first and second tube sections connected by an intermediate tube section. By this arrangement, upon the bumper system receiving a longitudinal impact, the first and second tube sections telescopingly collapse with a predictable and consistent rolling collapse.

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 system includes a tube made of a continuous material, such as heat-treatable steel. The tube has first and second ring sections connected by an intermediate section. In one aspect, the intermediate section is flared and/or pinched to cause one tube section to predictably telescopingly roll upon impact. In another aspect, one section is annealed to optimize elongation and yield properties to facilitate rolling upon impact. By this arrangement, upon the bumper system receiving a longitudinal impact, the first and second ring sections telescopingly collapse with a predictable and consistent rolling collapse. Methods related to the above are also disclosed.

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.
