    • 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.
    • 保险杠系统包括具有支架安装件的轧制管状梁,其焊接到后表面以安装到车辆框架轨道。 所示出的梁在其整个长度上具有连续的管状横截面,并且包括中心部分,角部形成端部部分和将中心部分的端部连接到端部部分的安装部分。 中心,端部和安装部分可以是线性的或类似的弯曲或不同的弯曲。 中心,端部和安装部分可以类似地或不同地局部退火,作为被调整到特定冲击负载标准的一部分,包括退火全部或部分横截面区域。 退火可以与辊成型过程一致进行,例如有助于在梁中形成紧密半径以满足包装/空间相关要求,或者可以是用于有利地影响选定的局部区域中的冲击强度的二次过程的一部分 。

    • A vehicle bumper beam includes front, rear, top and bottom walls and a reinforcement wall that define upper and lower tubes. The front wall includes a vertical section, an angled section, and a bent section. The reinforcement wall supports the angled section below the bent section to provide predictable and desired energy absorption. The angled section preferably includes an angled portion defining a first vertical dimension in the first tube and the vertical section defining a second vertical dimension, with a ratio of the first and second being about 1:3. Also preferably, the front wall is at least about 3 mm and the remaining walls are less than about 2.0 mm thickness, or more preferably the exterior ones of the remaining walls are less than about 1.7 mm. In one embodiment, the upper and lower tubes are spaced apart.
