VEHICLE BUMPER REINFORCEMENT
DRIVE
May 14, 2014
Obtaining excellent collision energy absorption performance and a function of preventing a vehicle from running onto or under another vehicle without increasing the number of components and weight. Since the curved portions 18 with low strength are provided at two positions that are symmetrical with respect to the center in the vehicle width direction, the bumper reinforcement for a vehicle 10 is easily deformed at the curved portions 18, and a sharp decrease in a load due to buckling of a load-input portion is suppressed, and thus, it is possible to obtain excellent collision energy absorption performance. In this case, since each of the curved portions 18 is configured by the single projecting portion 40, strength against a collision load from the projecting direction of the projecting portion 40 (from the front of the vehicle) is reduced. Since the width of each of the curved portions 18 is expanded upwardly and downwardly in the vehicle up-down direction, the function of preventing the vehicle from running onto or under another vehicle is obtained by the curved portions 18, and thus, the vehicle is restrained from running onto and running under the other vehicle without increasing the number of components and weight.
