Patent number: 10059290Abstract: An impact absorbing portion and a bumper reinforcement are formed in one piece, so an intermediate member for connecting the impact absorbing portion to the bumper reinforcement is no longer necessary. Therefore, the generation of stress concentration is able to be inhibited. As a result, load transmission efficiency with which a load is transmitted from the bumper reinforcement to the impact absorbing portion is able to be improved.Type: GrantFiled: June 10, 2015Date of Patent: August 28, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tetsuya Nakajima, Kazuki Sugie, Tetsuo Nuruki

Patent number: 9550463Abstract: A vehicle body end section structure is obtained that enables a spacer member that transmits load to a framework member in a small overlap collision to be suppressed from impinging on a wheel in a minor collision. The vehicle body end section structure comprises a pair of left and right framework members, a bumper framework section connected to leading end portions of the pair of framework members, and a spacer member that projects out from a jutting-out portion of the bumper framework section toward a framework member side. The spacer member is disposed such that a rotation trajectory of the spacer member about a connection location between the bumper framework section and the framework member, the connection location is positioned on an opposite side in the vehicle width direction of the spacer member, does not impinge on a wheel in plan view.Type: GrantFiled: December 9, 2013Date of Patent: January 24, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasuhiro Hara, Tetsuo Nuruki, Yoichi Tamura, Nobuhisa Ishiyama, Hiroshi Mizuo, Shintaro Kitakata, Hiroshi Kato, Yukio Oka
