Publication number: 20090184501Abstract: A side impact absorbing structure for a vehicle is provided. The structure includes an impact absorbing member which is accommodated in a car body side wall at a position corresponding to a seating region set on a seat, and a buffer unit which is accommodated in the car body side wall and cooperates with the impact absorbing member upon lateral collision to moderate an impact on a side portion of a passenger. The buffer unit includes a rigid body portion which is arranged at a position where the rigid body portion does not overlap the impact absorbing member in the car body side wall and the seating region when seen from the side of a car body.Type: ApplicationFiled: January 21, 2009Publication date: July 23, 2009Applicant: MAZDA MOTOR CORPORATIONInventor: Yasunari Hirotani

Patent number: 7393047Abstract: Disclosed is an automobile roof structure, which comprises a pair of right and left roof side rails 1, a transparent roof panel 4 attached to cover a space between the roof side rails 1, a sun shade 5 disposed slidably along a bottom surface of the transparent roof panel 4, and a shade support member 6 for supporting the sun shade 5 in a slidingly movable manner. Each of the roof side rails 1 includes a rail outer panel 7 and a rail inner panel 8 formed, respectively, with roof flanges 14, 15 which are oriented to protrude in a laterally inward direction of an automobile body and joined together. The roof flanges 14, 15, a lateral peripheral portion of the transparent roof panel 4, and the shade support member 6, are disposed within a given positioning zone where they overlap each other in top plan view.Type: GrantFiled: May 4, 2006Date of Patent: July 1, 2008Assignee: Mazda Motor CorporationInventors: Yasunari Hirotani, Katsumi Sakane, Shingo Kunihiro, Kazuhiro Tanaka, Asami Iwamoto, Masaki Nakaura

Patent number: 7328918Abstract: A seat belt device for a central portion of a rearmost row seat includes a retractor. The retractor is attached at a vehicle roof above a central passenger on the central seat portion of the rear row seat. More specifically, a pair of left and right roof rails are interconnected by a first reinforcement extending in a vehicle width direction before the central passenger, and the first reinforcement and a rear header are interconnected by a second reinforcement extending in a longitudinal direction. A retractor is attached at the first reinforcement. A seat belt withdrawn from the retractor is disposed so as to extend via a seat belt anchor disposed in the rear header.Type: GrantFiled: June 9, 2004Date of Patent: February 12, 2008Assignee: Mazda Motor CorporationInventor: Yasunari Hirotani

Publication number: 20060290167Abstract: A structure of an armrest protruding and extending toward a passenger from an inside wall of a vehicle compartment, comprises a trim body portion covering the inside wall, an armrest face portion extending in a substantially horizontal direction from the trim body portion toward an inside, and a support face portion extending continuously from the armrest face portion downward. There is provided a weak portion (deformation promoting portion) between the trim body portion and the armrest face portion to promote deformation with respect to a lateral load. Further, there is provided a garnish covering the weak portion from the vehicle compartment. Accordingly, both sufficient resistance of the armrest in use for the load applied in the vertical direction and proper impact-absorption function of the armrest during the vehicle side collision can be obtained.Type: ApplicationFiled: August 31, 2006Publication date: December 28, 2006Applicant: MAZDA MOTOR CORPORATIONInventors: Yasunari Hirotani, Shingo Kunihiro, Keiji Sekimoto
