Patent number: 9027695Abstract: A first projection portion projecting outward, in a vehicle width direction, from a front side frame is provided. A front end of the first projection portion is located at the same position, in the vehicle longitudinal direction, as a connection portion of a crash can to the front side frame or located in back of the connection portion. An outward side face of the first projection portion is configured to slant rearward and inward in a plan view. The first projection portion and a power unit are arranged to overlap each other in the vehicle longitudinal direction. Accordingly, an impact transmitted to a vehicle-compartment side in a small overlap collision can be reduced, restraining repair costs of the crash can broken in a low-speed collision as well as maintaining appropriate design flexibility of a vehicle-body front portion.Type: GrantFiled: April 1, 2013Date of Patent: May 12, 2015Assignee: Mazda Motor CorporationInventors: Satoshi Nakamura, Hiroaki Takeshita, Masanobu Kobashi

Patent number: 7845716Abstract: A support frame is provided to extend upward and rearward from a portion of a front side frame near a suspension tower substantially straight and connect to an upper portion of a hinge pillar. Accordingly, there can be provided a front structure of an automotive vehicle that can properly restrain a forward deformation of a cabin by transmitting an impact load at a vehicle frontal crash to the hinge pillar efficiently.Type: GrantFiled: April 24, 2008Date of Patent: December 7, 2010Assignee: Mazda Motor CorporationInventors: Shinji Kiyotake, Takayuki Kimura, Masanobu Kobashi, Hidenori Matsuoka, Sakayu Terada

Patent number: 7690552Abstract: In a first step, a roof panel and a front header are joined at plural frictional spot joint portions at a front-end frictional joint area, and the roof panel and a rear header are joined at plural frictional spot joint portions at a rear-end frictional joint area. The roof panel and a side roof rail are joined at plural frictional spot joint portions at left-side and right-side frictional joint areas. Subsequently, in a second step, the members are joined at the plural rivet joint portions at a border area of the above-described joint areas, and the members are joined at plural rivet joints at a bounder area of the above-described joint areas. Accordingly, there can be provided a joining method and structure of metal members that can properly reduce deformation due to a thermal strain.Type: GrantFiled: December 19, 2007Date of Patent: April 6, 2010Assignee: Mazda Motor CorporationInventors: Toshiyuki Gendou, Mitsugi Fukahori, Tetsukan Takasue, Mitsuaki Kitamura, Takayuki Kimura, Masanobu Kobashi
