Patent number: 6705653Abstract: A shock absorbing member for a vehicle is designed to absorb the impact energy in a plastic deformation manner to absorb the axial compressive load. The shock absorbing member includes a hollow member whose cross-section is roughly constant and whose axis is adapted to extend forward and rearward of the vehicle. A flange is formed on the hollow member roughly along the axis of the hollow member and projects by an amount increasing gradually from one side toward the other side of the axis.Type: GrantFiled: November 21, 2001Date of Patent: March 16, 2004Inventors: Terutsugu Gotanda, Shinichi Haneda, Kazuo Mori, Daichi Kunishi, Kazunobu Nuno, Kazunari Azuchi

Patent number: 6698968Abstract: A first frame section is hollow and has a substantially uniform polygonal cross-sectional shape. An axial load is applied to the first frame section. A second frame section is hollow and has a substantially uniform polygonal cross-sectional shape. The axial load is transmitted from the first frame section to the second frame section. A transmitting portion is provided in at least one of the first and second frame sections. The transmitting portion receives the axial load that acts on each edge of the first frame section and transmits the axial load to each edge of the second frame section.Type: GrantFiled: November 20, 2001Date of Patent: March 2, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazutomo Kajiwara, Yuzo Konishi, Kiyohito Morimoto, Seiji Sakai, Terutsugu Gotanda, Shinichi Haneda, Kazuo Mori, Kazunari Azuchi, Kazunobu Nuno

Patent number: 6502874Abstract: Load is applied to a bumper reinforce. Two hollow crash boxes are coupled to the bumper reinforce. Each crash box has a substantially constant cross section, an axis and an open end. When load is applied to the bumper reinforce, each crash box is plastically deformed in the axial direction for absorbing the load. The bumper reinforce includes projections. Each projection corresponds to one of the crash boxes and faces part of the open end of the corresponding crash box. The projections reduce the load at the beginning of plastic deformation.Type: GrantFiled: December 21, 2001Date of Patent: January 7, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazutomo Kajiwara, Yuzo Konishi, Kiyohito Morimoto, Seiji Sakai, Terutsugu Gotanda, Shinichi Haneda, Kazuo Mori, Kazunari Azuchi, Kazunobu Nuno
