Patent number: 11801799Abstract: In order to absorb collision energy so as to prevent an increase in reaction force against a pedestrian to a level higher than or equal to a certain level during collision, a bumper absorber of the present invention includes: a trunk part that extends in an X direction and that is simply compressed in the X direction in response to an impact; and a branch part that branches off from the trunk part toward a rear of a vehicle body, the branch part having a branching part in which the branch part branches off from the trunk part and which is provided with a breakage inducing part that causes breakage between the trunk part and the branch part in response to the impact.Type: GrantFiled: December 14, 2021Date of Patent: October 31, 2023Assignees: KANEKA CORPORATION, Chugai Co., Ltd., TOYOTA JIDOSHA KABUSHIKI KAISHA, SUBARU CORPORATIONInventors: Mitsuhiro Tamura, Seiji Sawai, Yusuke Kikuchi, Yuuki Nakamura, Shota Kotake, Yoshikazu Yukimoto

Patent number: 7017978Abstract: The present invention the related to a shock absorption pad for a vehicle for protecting occupant's lower legs. The shock absorption pad according to the present invention on which an occupant's foot is placed is attached on a surface of a toe board. The shock absorption pad includes a first shock absorption layer provided on the occupant's foot-placing side for absorbing an impact generated in a boundary region at which an energy absorption load of a vehicle body becomes different in a deformation process of the vehicle body at a vehicle crash, and a second shock absorption part provided on the toe board's side for absorbing an impact generated in a region in which the energy absorption load is high.Type: GrantFiled: March 28, 2003Date of Patent: March 28, 2006Assignees: Toyota Jidosha Kabushiki Kaisha, Sekisui Kaseihin Kogyo Kabushiki Kaisha, Chugai Co., Ltd.Inventors: Takeshi Murakami, Taku Fukuyama, Takaharu Okada
