Patent number: 8931826Abstract: A load transmitting member comprising a rising face portion rising from a floor panel and a facing face portion facing a portion of the side panel between a rear edge portion of a rear-door opening portion and a rear-wheel house portion and having its short longitudinal width is arranged on an inward side of a side panel. The load transmitting member is fixed to a front portion of the rear-wheel house portion directly or via a bracket. The load transmitting member can be arranged so as not to prevent a smooth ingress/egress action of a passenger, and a proper load-transmission function of the load transmission member when the impact load is inputted to a rear door from the vehicle side can be attained so as to effectively restrain the rear door from coming into a vehicle compartment.Type: GrantFiled: August 16, 2013Date of Patent: January 13, 2015Assignee: Mazda Motor CorporationInventors: Takashi Yoshimura, Shigeaki Watanabe, Sakayu Terada, Katsuyoshi Ishigame, Yuichi Sugimura

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
