摘要： Flanges (68) are provided on outer sides (in an upper-lower direction) of a pair of narrow side walls (66) of a crash box (50). Each of flanges (68) is provided to be connected to the narrow side wall (66) at the central portion thereof, and the both lateral portions thereof (wing-like flanges (70a, 70b)) extend parallel to the narrow side walls (66) and in the opposite directions relative to each other. Therefore, even when an impact load is applied to the crash box (50) in an oblique direction of the vehicle, owing to disposition of the flanges (68) the crush box (50) is suppressed from lateral falling, so that excellent impact-absorbing property is stably obtained. Because the flanges (68) are formed parallel to the narrow side walls (66), the impact absorbing member can be appropriately prevented from the lateral falling resulted from the impact load acting in an oblique direction of the vehicle, and can be compactified in size. As a result, mountability on a vehicle is improved.

摘要翻译： 法兰（68）设置在碰撞箱（50）的一对窄侧壁（66）的外侧（上下方向）上。 每个凸缘（68）设置成在其中心部分处连接到窄侧壁（66），并且其两个侧部（翼状凸缘（70a，70b））平行于窄侧壁（ 66）并且在相对于彼此的相反方向上。 因此，即使当碰撞箱（50）在车辆的倾斜方向上施加冲击载荷时，由于凸缘（68）的设置，也可以抑制挤压箱（50）的横向下落， 稳定地获得吸收性能。 由于凸缘（68）平行于窄侧壁（66）形成，因此能够适当地防止冲击吸收部件因沿着车辆的倾斜方向的冲击载荷而产生的横向下降，并且能够紧凑化 。 结果，车辆的安装性提高。

摘要： Of side wall portions (60a, 60b) of a tubular body portion (52) mainly constituting an impact absorbing member (50), a wider side wall portion (60a) on the vehicle inner side is provided with a projecting rib (70) projects outward in the direction perpendicular to the axis of the body portion. The projecting rib (70) extends from an axial end (52a) adjacent to a mounting plate (54) and parallel to the axial direction of the body portion. Therefore, even when an impact load is applied to the impact absorbing member (50) in an oblique direction with respect to the vehicle to generate a moment load, the existence of the projecting rib (70) prevents the impact absorbing member from falling down laterally. Accordingly, excellent impact-absorbing properties are stably obtained. The projecting rib (70) is formed not to reach the load input side, i.e., the axial end (52b) adjacent to a mounting plate (56), where collapse starts. Therefore, no load increase occurs in a crash initial stage to well maintain impact-energy-absorbing properties.

摘要： A vehicle bumper beam, attached at its ends to side members of a vehicle through respective impact absorbing members. The bumper beam is press-formed into a predetermined shape. A width W2 of a connecting portion at an end portion thereof is larger than a width W1 of a connecting portion at a center portion thereof. A height H1 of a protruding portion at an end portion thereof is smaller than a height H2 of a protruding portion at a center portion thereof. A connecting portion between the protruding portions cooperates with the protruding portions to define an M-shaped configuration. The opposite end portions have a bending strength higher than a crush strength of the impact absorbing members.

摘要： A crash energy absorption member formed from a tubular body for absorbing impact energy by buckling when it receives an impact load in the axial direction from one end in the axial direction. It has a transverse cross-sectional shape along at least a portion in the axial direction which is a closed cross section having a plurality of vertices in which there is no flange on the outside of the closed cross section, and in a region of at least one side of a basic cross section formed from the largest outline obtained by connecting a portion of the plurality of vertices by straight lines, a groove which is recessed towards the inside of the outline is provided in a location other than at an end point of the side. Thus, the crash energy absorption member can achieve a prescribed amount of shock absorption by stably buckling in the axial direction without bending and without an increase in weight due to the addition of a partition or due to an increase in plate thickness.
