Patent number: 11345295Abstract: An impact absorbing structure for a vehicle according to the present invention includes: a resin frame member extending in a vehicle front-rear direction and having an opening portion in a surface thereof on one side in a vehicle width direction; and a strut member disposed in the opening portion of the frame member. The frame member includes a frame body having the opening portion, and a rib protruding at least either upward or downward from the frame body and extending in the vehicle front-rear direction. The strut member is disposed between a pair of opening edges for defining an upper edge and a lower edge of the opening portion and at a position abuttable against the paired opening edges, when the frame member is deformed by input of a load at a time of oblique collision from upward or oblique collision from downward.Type: GrantFiled: December 11, 2018Date of Patent: May 31, 2022Assignee: MAZDA MOTOR CORPORATIONInventors: Chikara Kawamura, Tsuyoshi Nishihara, Kazutaka Ishikura, Hiroaki Takeshita, Tsuneki Shimanaka, Taiki Yotsuyanagi, Yoshiaki Murakami

Patent number: 10479302Abstract: An impact absorbing structure includes an impact absorbing member made of CFRP, and the impact absorbing member includes a pair of left and right side wall portions and upper and lower coupling wall portions each coupling the side wall portions. Each of the pair of side wall portions includes a plurality of curved portions. Each of the curved portions is formed such that a leftward/rightward direction depth thereof decreases toward a front side. Each of the pair of side wall portions includes: a plurality of first carbon fibers arranged to extend in a forward/rearward direction and constituting most of reinforced fibers contained in the side wall portion; and a plurality of second carbon fibers arranged to extend in a direction intersecting with the first carbon fibers. The plurality of second carbon fibers are arranged at both thickness direction end vicinity parts of each of the side wall portions.Type: GrantFiled: November 8, 2016Date of Patent: November 19, 2019Assignee: Mazda Motor CorporationInventors: Chikara Kawamura, Taiki Yotsuyanagi, Hiroaki Takeshita, Tsuyoshi Nishihara, Tsuneki Shimanaka, Takayuki Kimura, Yoshiaki Murakami

Patent number: 9868472Abstract: A bonnet inner panel includes a central protrusion portion protruding upward in a vehicle elevational view and a rear protrusion portion located in back of the central protrusion portion, which are arranged side by side in a vehicle longitudinal direction, a deep-drawn groove is provided between the both protrusion portions to extend in a vehicle width direction, and a hinge reinforcement is provided to extend from a position beside the rear protrusion portion to a position at a rear end of the central protrusion portion, passing through beside the deep-drawn groove. Thereby, the hinge support rigidity of the rear portion of the bonnet having the central protrusion portion can be increased, so that occurrence of any improper deflection or vibration caused to the bonnet by the traveling vibration, the traveling-air pressure or the like can be prevented.Type: GrantFiled: August 14, 2015Date of Patent: January 16, 2018Assignee: MAZDA MOTOR CORPORATIONInventors: Kohji Takada, Kozo Ishizuka, Hirokazu Yamauchi, Akira Miyake, Yousuke Inamitsu, Hideaki Fujii, Takashi Hamada, Soukichi Kikuchi, Atsushi Koriyama, Tsuyoshi Nishihara, Izumi Sadanaga
