Patent number: 8403096Abstract: A rear floor panel extends rearwardly from a kick-up portion formed at a rear portion of a floor panel. A lateral connecting member which constitutes part of a rear suspension connects to supporting portions to support both rear wheels. An engine is arranged below the rear floor panel and in front of the lateral connecting member. A generator is arranged below the rear floor panel and in back of the engine. Accordingly, the traveling stability of the vehicle can be improved and the yaw inertia moment of the vehicle can be decreased.Type: GrantFiled: August 31, 2010Date of Patent: March 26, 2013Assignee: Mazda Motor CorporationInventors: Tomoo Taguchi, Hiromichi Kawamura, Kouji Iwasaka

Patent number: 7658440Abstract: An arrangement structure for an auxiliary component of a vehicle includes a floor panel defining the bottom surface of the passenger compartment. The floor panel includes a first kick-up portion and a second kick-up portion disposed in side-by-side relation to the first kick-up portion in a lateral direction of a vehicle body. The second kick-up portion is formed to have a height greater than that of the first kick-up portion. A first seat is disposed on the first kick-up portion, a second seat is formed to have a smaller size than that of the first seat and disposed on the second kick-up portion, and a cross member is joined along the second kick-up portion in the lateral direction to form a closed section therebetween. The arrangement structure of the present invention allows a vehicle to have a low overall-height compact body while achieving enhanced layout flexibility and assuring a passenger compartment space.Type: GrantFiled: March 30, 2006Date of Patent: February 9, 2010Assignee: Mazda Motor CorporationInventors: Isao Tohda, Kouji Iwasaka, Katsumasa Sogame, Shigeyuki Mori

Publication number: 20050011640Abstract: A rear air conditioning unit is disposed behind a rear bulkhead separating a rear portion of a passenger compartment. The rear air conditioning unit takes in inside-and-outside air for air conditioning via a rear cowl portion disposed above the rear bulkhead head and blows off conditioned air into the passenger compartment. Accordingly, since a layout of an air conditioning unit disposed at the front side of the vehicle is omitted, an engine as a heavy article can be located at the center side of the vehicle and a yaw inertia moment of the vehicle can be reduced, thereby improving maneuverability and stability of the vehicle and dynamic performance of the vehicle. Further, a layout of the rear air conditioning unit and induction of the inside-and-outside air can be made compatible.Type: ApplicationFiled: June 9, 2004Publication date: January 20, 2005Applicant: MAZDA MOTOR CORPORATIONInventors: Isao Tohda, Kouji Iwasaka, Yukio Nakamura

Patent number: 6767044Abstract: A roof construction for a vehicle that uncovers a roof space above a passenger compartment of a vehicle body and covers the roof space, partly or fully, comprises a roof assembly, e.g. front, intermediate and rear roof panels, that is movable relatively to the vehicle body in a longitudinal direction of the vehicle body so as to selectively shift between three positions, namely a closed position where the roof space is fully closed, a partly open position where the roof space is partly open and a fully open position where the roof space is fully open and a prop link mechanism operative to shift the roof assembly into a selected one of the three positions and to fixedly support the roof assembly in the selected position. During shifting the roof assembly into a selected position, the front and intermediate roof panels are superposed and held horizontally in position.Type: GrantFiled: August 26, 2002Date of Patent: July 27, 2004Assignee: Mazda Motor CorporationInventors: Isao Tohda, Haruo Ohe, Kouji Iwasaka
