Vehicle opening/closing member damper apparatus and vehicle opening/closing member stopper apparatus
Patent number: 9493976Abstract: A damper apparatus includes a piston having a flange-shaped piston main body and piston rods which project from both ends of the piston main body, a cylinder having a cylinder main body which accommodates the piston main body slidably and cylindrical portions which support slidably the piston rods, respectively, a fastener which is attached to the one cylindrical portion so as to secure the cylinder to an opening/closing member, and a coil spring which biases the one piston rod to project from the other cylindrical portion such that a distal end portion of the piston rod abuts a circumferential edge of an opening portion of a vehicle.Type: GrantFiled: June 22, 2012Date of Patent: November 15, 2016Assignees: PIOLAX INC., HONDA MOTOR CO., LTDInventors: Ryu Hattori, Kenji Morita, Nobuya Shinozaki, Akira Sakata, Tomoya Yabu, Hisashi Yamamoto, Hirokuni Kumekawa, Toshifumi Gocho -
Patent number: 9187130Abstract: A vehicle body lateral section contains an upper stiffener, which extends upward from a rear wheel housing and overlaps a bottom end of a pillar inner. The upper stiffener is provided with an extension that continues to the pillar inner. The vehicle body lateral section has: a first closed-cross-section section formed from the rear wheel housing and the upper stiffener; and a second closed-cross-section section formed from the pillar inner and a pillar stiffener.Type: GrantFiled: May 17, 2012Date of Patent: November 17, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Yasuyuki Katou, Hirokuni Kumekawa

Patent number: 9010847Abstract: A vehicle body rear structure includes a left and right rear-side frame and a rear panel assembly. The left and right rear-side frames extend in the front-back direction of the vehicle body. The rear panel assembly forms a closed-cross-section section extending in the direction of vehicle width intersecting the rear-side frames, is provided to the back end of the rear-side frames, and configures the bottom of a vehicle body rear opening. The rear panel assembly is provided with a bulkhead that is disposed in the closed-cross-section section at the upper surface of the rear-side frames, and that partitions the interior of the closed-cross-section section with surfaces oriented in the direction of vehicle width.Type: GrantFiled: May 17, 2012Date of Patent: April 21, 2015Assignee: Honda Motor Co., Ltd.Inventors: Yasuyuki Katou, Hirokuni Kumekawa, Yasunori Takeda

Patent number: 7407223Abstract: In an automotive floor panel assembly comprising a floor panel (1) stamp-formed of sheet metal and including a recess (21, 22) defining an upper concave surface and a lower convex surface, a compound longitudinal floor frame is formed by a lower reinforcement (24) extending longitudinally across a part of the lower convex surface of the floor panel and an upper reinforcement (25) extending longitudinally across a part of the upper concave surface of the floor panel. The lower and upper reinforcements include a first vertical wall having an upper edge closely following a contour of the lower convex surface a second vertical wall having a lower edge closely following a contour of the supper concave surface, respectively. The compound longitudinal floor frame is thus provided with a substantially constant cross section and extends substantially linearly over the entire length of the floor panel and hereby.Type: GrantFiled: March 8, 2006Date of Patent: August 5, 2008Assignee: Honda Motor Co., Ltd.Inventors: Hideaki Ito, Hirokuni Kumekawa
