Patent number: 9623910Abstract: There are provided a hinge pillar comprising an outer panel and an inner panel which form a closed cross section extending vertically, a hinge pillar reinforcement provided in the closed cross section, a front door attached to the hinge pillar via a pair of upper-and-lower door hinges, and a hinge bracket attaching the lower door hinge to the hinge pillar reinforcement, the hinge bracket being provided to face a front wheel in a longitudinal direction. Herein, the hinge bracket has a lower strength than a portion of the hinge pillar reinforcement where the hinge bracket is provided. Accordingly, when receiving a collision load from the front wheel, the hinge bracket changes a contact portion of the front wheel to the hinge pillar so as to guide the retreating front wheel outward in a vehicle width direction.Type: GrantFiled: August 14, 2015Date of Patent: April 18, 2017Assignee: MAZDA MOTOR CORPORATIONInventors: Daisuke Kiyoshita, Masanori Fukuda, Toshiharu Ikeda, Soukichi Kikuchi, Takashi Hamada

Patent number: 6793276Abstract: A floor is partitioned into a plurality of areas S1 to S4 by a floor tunnel portion 11, side frames 13, side sills 12, and cross members 7, 8, 15, and 16, and the rigidity of the floor panels of the areas S1 to S3 is adjusted by rigidity adjustment portions 20, 21, 22, 23, and 25. These floor panels are set such that their natural frequency in a 2×1 mode, in which two antinodes are generated in the length direction of the automobile and one antinode is generated in the width direction of the automobile, is 240 to 260 Hz. Thus, a reduction in road noise due to automobile tire cavity resonance is achieved.Type: GrantFiled: July 29, 2002Date of Patent: September 21, 2004Assignee: Mazda Motor CorporationInventors: Tsuyoshi Sugihara, Takanobu Kamura, Minoru Sunada, Yoshio Fujii, Shoji Nanba, Toshiharu Ikeda, Gunji Yoshii, Tsutomu Naganuma

Patent number: 5246263Abstract: In a rear body structure of a vehicle, a rear pillar forms a rear edge portion of an opening for a door which is formed on one side portion of the vehicle body. A rear fender is connected to the rear pillar and extends rearwardly therefrom. A suspension tower is connected to the rear fender at a distance from the rear pillar. A reinforcement is connected to upper portions of the rear fender and the suspension tower so as to extend in the longitudinal direction of the vehicle body. An impact absorbing portion is provided between the rear pillar and the suspension tower to prevent the rear pillar from being deformed in response to forward displacement of the suspension tower which is caused by a forward impact load acting on the suspension tower.Type: GrantFiled: January 15, 1992Date of Patent: September 21, 1993Assignee: Mazda Motor CorporationInventors: Matsuhiro Tanaka, Toshiharu Ikeda, Shuji Muraoka
