Patent number: 8297668Abstract: 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.Type: GrantFiled: December 16, 2009Date of Patent: October 30, 2012Assignee: Toyoda Iron Works Co., Ltd.Inventors: Makoto Nakanishi, Mitsutoshi Kano

Patent number: 8287013Abstract: 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.Type: GrantFiled: January 19, 2011Date of Patent: October 16, 2012Assignee: Toyoda Iron Works Co., Ltd.Inventors: Mitsutoshi Kano, Makoto Nakanishi, Kenji Tamura

Patent number: 7665586Abstract: A crash energy absorption member is provided which has excellent crash energy absorbing properties with the ability of repeated buckling in a stable manner, a high average load at the time of collapse, and the maximum load which is within a range which does not break other members. It is a crash energy absorption member which preferably has a transverse cross-sectional shape of an octagon and which is intended for absorbing impact energy by buckling in the lengthwise direction into a shape of bellows when it receives an impact load. With respect to at least one side forming the transverse cross-sectional shape, when the angle formed by the two sides which adjoin the opposing ends of the one side is ?, the relationship between the length L1 of the one side and the distance L2 between the two furthest ends of the two sides interposing the one side satisfies the following equation: 0<L1/L2<1/{2×sin(?/2)+1}.Type: GrantFiled: January 27, 2006Date of Patent: February 23, 2010Assignees: Sumitomo Metal Industries, Ltd., Toyoda Iron Works Co., Ltd.Inventors: Kenji Tamura, Yoshiaki Nakazawa, Michitaka Yoshida, Katsutoshi Takagi, Mitsutoshi Kano
