  • Patent number: 9821739
    Abstract: An automobile bumper is provided in which the bumper beam includes a middle curved part that curves concavely rearwards and a pair of left and right curved parts that curve convexly rearwards, and the left and right curved parts includes a rear side frame connecting part and a load input part projecting rearwards the most among the bumper beam parts. Since the bumper beam includes a compression-resistant reinforcing part provided along the inner face in the fore-and-aft direction of the load input part, and an extension line of the compression-resistant reinforcing part is directed toward the vicinity of the load input point of the load input part, supporting the compressive load by the compression-resistant reinforcing part to thus prevent the bumper beam from being destroyed enables the strength toward bending deformation to be enhanced without reinforcement by increasing the plate thickness of the bumper beam.

  • Patent number: 9487168
    Abstract: An automobile bumper beam to be disposed in a vehicle width direction includes: a small sectional area portion at a center in the vehicle width direction; paired sectional area changing portions continuous to outsides in the vehicle width direction of the small sectional area portion; and paired large sectional area portions continuous to outsides in the vehicle width direction of the sectional area changing portions. The small sectional area portion projects most outward in a front-rear direction at paired impact load input portions. Thus, impact load in minor collision is inputted as two-point concentrated load to the paired input portions of a bumper beam body, reducing a peak value of bending moment acting on the body, and the sectional area changing portions and large sectional area portions bear the moment, thereby enhancing strength of the body, reducing its thickness and weight, and achieving an excellent collision energy absorbing effect.
