Patent number: 8950778Abstract: The strength of an instrument panel member (12) at a portion thereof between a steering shaft support part (16) and a linking part (13) on the side near a steering shaft (11) is set lower than the strength of the instrument panel member (12) at a portion thereof between the steering shaft support part (16) and a linking part (14) on the far side from the steering shaft (11), with respect to a load input through the linking part (13) on the side near the steering shaft (11) in the vehicle body front-rear direction. The above configuration makes it possible to suppress movement of a steering wheel inward in the vehicle width direction to thereby securely restrain a vehicle occupant by an airbag at the time of a vehicle frontal collision.Type: GrantFiled: July 30, 2012Date of Patent: February 10, 2015Assignee: Mazda Motor CorporationInventors: Masanobu Fukushima, Hiroto Kido, Hiromasa Honji

Patent number: 8393673Abstract: Part of a front side frame is configured to be deformed so as to bend outwardly, in a vehicle width direction, by a collision load in a vehicle frontal collision. A sub frame provided at a lower portion of a front vehicle body is joined to the front side frame via a reinforcement. A front portion of the reinforcement is located at a position which corresponds to a bending portion of the front side frame which is to be deformed so as to bend outwardly, in the vehicle width direction, by the collision load in the vehicle frontal collision. Accordingly, the bending of the front side frame at its bending portion when the collision load acts in the vehicle frontal collision can be promoted, so that the collision load against passengers can be decreased securely.Type: GrantFiled: October 14, 2010Date of Patent: March 12, 2013Assignee: Mazda Motor CorporationInventors: Sakayu Terada, Hiromasa Honji, Masanobu Fukushima

Patent number: 8267429Abstract: A positioning pin and a bolt hole positioned near this pin are provided at a plate-shaped rear-portion attachment face portion of a suspension cross member. A positioning hole having the positioning pin inserted thereinto and a bolt hole positioned near this positioning hole are provided at a tunnel frame on the side of a vehicle. The rear-portion attachment face portion and the tunnel frame are fastened by a bolt inserting into the bolt holes together with a nut. Accordingly, the support rigidity of the suspension cross member during the normal vehicle traveling can be secured and the smooth retreat of the power unit to restrain the collision load from having bad influence on passengers in the vehicle frontal collision can be achieved.Type: GrantFiled: December 23, 2010Date of Patent: September 18, 2012Assignee: Mazda Motor CompanyInventors: Hiroaki Takeshita, Takahiro Otani, Masanobu Fukushima, Ryuichi Kusama, Hiromasa Honji

Patent number: 7887123Abstract: A front side frame includes a bend portion which is operative to bend outward when an impact load acts on the front side frame from ahead. The bend portion is provided in a specified location such that the bend portion in a bending state substantially contacts a damper of the suspension from a vehicle front side. Accordingly, a rear end of the front side frame can be prevented properly from moving back when the impact load acts on the front side frame from ahead.Type: GrantFiled: October 29, 2008Date of Patent: February 15, 2011Assignee: Mazda Motor CorporationInventors: Hiromasa Honji, Masaki Ueno, Sakayu Terada, Michinari Watanabe
