PROBLEM TO BE SOLVED: To provide a bumper reinforcement capable of improving a peak load per unit mass and an energy absorption amount by suppressing a sectional collapse of a closed cross-sectional shape of a so-called reverse hat shape.SOLUTION: A bumper reinforcement 1 comprises an upper reinforcement body 10A and a lower reinforcement body 10B provided in a long box body 2 at the center of the long box body 2 in a longitudinal direction. An upper rear face 21A of the upper reinforcement body 10A and a lower rear face 21B of the lower reinforcement body 10B are fixed to a rear face 4 of the long box body 2. A top face 24 of the upper reinforcement body 10A faces a top face 5 of the long box body 2 in the vicinity of the top face 5 of the long box body 2. A lower face 25 of the lower reinforcement body 10B faces a lower face 6 of the long box body 2 in the vicinity of the lower face 6 of the long box body 2. An upper front face 26A of the upper reinforcement body 10A and a lower front face 26B of the lower reinforcement body 10B are fixed to a long front face plate 3.SELECTED DRAWING: Figure 5

    【課題】いわゆる逆ハット型の閉断面形状の断面崩れを抑制することにより、単位質量あたりのピーク荷重及びエネルギー吸収量を向上させることが可能なバンパリインフォースメントを提供する。【解決手段】バンパリインフォースメント1は、長尺状箱体2の長尺方向中央で長尺状箱体2に内設された上側補強体10Aと下側補強体10Bを備えている。上側補強体10Aの上側後面21A及び下側補強体10Bの下側後面21Bは、長尺状箱体2の後面4に固定される。上側補強体10Aの上面24は、長尺状箱体2の上面5近傍で長尺状箱体2の上面5に対向する。下側補強体10Bの下面25は、長尺状箱体2の下面6近傍で長尺状箱体2の下面6に対向する。上側補強体10Aの上側前面26A及び下側補強体10Bの下側前面26Bは、長尺状前面板3に固定される。【選択図】図5
