Publication number: 20120212009Abstract: A vehicle body (11) including: a tunnel cross-member (28) extending in the vehicle's widthwise direction along the lower surface of a tunnel section (18) of the floor panel (19); left and right side-frame extensions (22, 22) extending rearward along the lower surfaces (31, 32) of the dashboard (15) from the rear ends of left and right front side-frames (16, 16). The left and right side-frame extensions each bifurcate into a side sill-side extension (43, 43) which, while tilting, extends rearward and outward in the vehicle's widthwise direction from the rear end of each of the left and right side-frame extensions to a side sill (17, 17), and into a tunnel-side extension (44, 44) which, while tilting, extends rearward and inward in the vehicle's widthwise direction from the rear end of each of the left and right side-frame extensions to the tunnel cross-member. The tilt of the side sill-side extensions and the tilt of the tunnel-side extensions are substantially the same.Type: ApplicationFiled: October 29, 2010Publication date: August 23, 2012Applicant: HONDA MOTOR CO., LTD.Inventors: Manabu Ishizono, Takumi Tsuyuzaki, Kosaku Tomozawa

Publication number: 20120187720Abstract: Side beam extends from a sub frame, mounted to front side frames, to a front frame section, and includes: a lower impact absorbing bar member having a horizontal intermediate portion joined to the sub frame, and a slanting portion extending upward from the intermediate portion; and a bent impact absorbing member joined to the slanting portion and front frame section and having a smaller strength against an impact than the bar member. Skid plate is mounted to a lower cross beam constituting a lower portion of the frame section and projects forward from the cross beam. Lower impact absorbing bar member is mounted to the cross beam and extends rearward, and an impact absorbing projecting member is provided in front of the bar member. The absorbing projecting member defines a closed sectional shape in conjunction with a rear portion of the skid plate.Type: ApplicationFiled: January 20, 2012Publication date: July 26, 2012Applicant: HONDA MOTOR CO., LTD.Inventors: Kosaku Tomozawa, Yushi Nakao, Takeshi Yoshimoto, Manabu Ishizono

Publication number: 20090102233Abstract: A vehicle body frame structure having two closed cross sections is disclosed. Each of the closed cross sections is isolated in a longitudinal direction of the vehicle body frame by barriers and structural foam fillers. The barriers are spot welded to the front and back of a reinforcement panel of the vehicle body frame.Type: ApplicationFiled: October 16, 2008Publication date: April 23, 2009Applicant: HONDA MOTOR CO., LTD.Inventor: Kosaku Tomozawa

Patent number: 7331626Abstract: In an automotive vehicle body including a first annular frame (29) formed by front pillars (11, 12), a second annular frame (34) formed by center pillars (13, 14) and a front door (7) internally provided with a front door beam (51) and fitted between the front pillar and center pillar one each side of the vehicle body, the front door beam overlaps the first annular frame and second annular frame as seen from sideways, and includes a door beam main body (61) providing a channel member having an open side facing inboard and a tension wire (71) extending along an inboard side of the door beam main body. Thereby, when another vehicle hits the front door from sideways, because the front door beam overlaps the first annular frame and second annular frame as seen from sideways, the impact energy can be effectively transmitted to the vehicle body. Furthermore, because the door beam main body supports a compressive load while the tension wire supports a tensile load, deformation of the door beam is minimized.Type: GrantFiled: November 3, 2006Date of Patent: February 19, 2008Assignee: Honda Motor Co., Ltd.Inventors: Takeshi Yoshimoto, Hitoshi Kato, Kosaku Tomozawa, Kazuo Arai
