Patent number: 8292019Abstract: A shock absorbing member is supported on a shock absorbing member support bracket fixed onto a floor tunnel sandwiched between left and right front seats. Therefore, it is possible to allow the front seats to interfere with the shock absorbing member so that the member can absorb collision energy at a time of a side collision of a vehicle. Because a lower portion of a front wall connected to an inverted-U-shaped inner face of the shock absorbing member is connected to an upper portion of a front wall of the shock absorbing member support bracket, the front wall of the shock absorbing member support bracket receives a load of the side collision in a shearing direction. Accordingly, it is possible to increase strength of the front wall of the shock absorbing member support bracket against the side collision, prevent the shock absorbing member from falling down sideways, and enhance the shock absorbing effect.Type: GrantFiled: October 15, 2010Date of Patent: October 23, 2012Assignee: Honda Motor Co., Ltd.Inventors: Makoto Hisazumi, Kenichiro Soyama, Yoshiyuki Toba

Patent number: 8231166Abstract: A member of a vehicle frame structure includes an extension portion that extends in a longitudinal direction and a kick portion positioned behind, and below the extension portion. Buckling lines are formed in parallel with each other in the extension portion, and each of the buckling lines is inclined such that a lower end is positioned ahead of an upper end in a side view. If a collision load is applied from a front side of a vehicle at the time of vehicle collision, the extension portion is deformed along the buckling lines, and a front end of the extension portion is displaced downward. Therefore, a vertical offset between the front end of the extension portion and the kick portion is reduced, thereby reducing a bending moment applied to the kick portion. Accordingly, the required yield strength of the kick portion can be set to a lower value.Type: GrantFiled: February 7, 2008Date of Patent: July 31, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventor: Takeo Mori

The sub-frame 7 distributedly transmits an offset collision load to a rear portion 4A of a right front side member 4, and right and left tunnel reinforcements 5 and 5 mainly through four paths of a right beam 7D, a right load transmission beam 7J2, and right and left load transmission beams 7J3 and 7J4 of an intermediate portion.Type: ApplicationFiled: December 5, 2008Publication date: October 21, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Naoya Kosaka, Koji Tamakoshi, Takeo Mori

Patent number: 7798564Abstract: A reinforcing member for vehicles comprises a pair of fixed parts fastened on spaced-apart portions of a vehicle body, and a bar body for connecting the respective fixed parts. A rotation allowing mechanism is provided on at least one of the fixed parts in order to allow the bar body to rotate with respect to the vehicle body. Therefore, the respective two portions of the vehicle body, on which the fixed parts are fastened respectively, are allowed to have angle variations to each other without changing the space between the two portions of the vehicle body. Consequently, the rigidity of the entire vehicle body can be improved without the degradation in the drivability and the ride comfortableness of the vehicle.Type: GrantFiled: December 22, 2005Date of Patent: September 21, 2010Assignee: Fuji Jukogyo Kabushiki KaishaInventors: Toshihiro Doi, Hideharu Tatsumi, Toshihisa Sakuma, Katsuyoshi Tanaka, Hiromi Tamou, Kouichi Hirota

Publication number: 20100201112Abstract: A system for providing protection to a vehicle occupant during a side impact event is disclosed. The system includes an outer panel, which may be a vehicle door outer sheet metal, an inner panel, which may be a vehicle door trim, and an elongated structural member disposed between the outer panel and the inner panel. The elongated structural member is generally disposed perpendicularly with respect to the inner and outer panels and is in general alignment with the pelvic area of the adjacent occupant. The elongated structural member may have an I-beam configuration which extends from the outer panel to the inner panel in the occupant's pelvic zone. The elongated structure may progressively crush during the impact event while pushing the occupant. During an impact event, the elongated structure is pushed vehicle-inward and provides pelvic support to the adjacent occupant.Type: ApplicationFiled: February 6, 2009Publication date: August 12, 2010Applicant: Ford Global Technologies, LLCInventors: Thiag Subbian, Nagaraj Mariyappa, Wei Richard Wang

Patent number: 7770927Abstract: A system for absorbing energy in a vehicle includes a pair of laterally spaced upper and lower side rails which extend along a longitudinal axis. The lower side rails are disposed below the upper side rails. An upper member extends transverse to the longitudinal axis and interconnects the upper side rails. A lower member extends transverse to the longitudinal axis and interconnects the lower side rails. The upper and lower members are each disposed to transmit energy from the upper and lower members through the respective upper and lower side rails. The upper and lower members are configured to simultaneously deform upon impact of the vehicle with an object and transfer a force generated from impacting the object to the upper and lower side rails, respectively.Type: GrantFiled: April 18, 2008Date of Patent: August 10, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Bhushan W.

Patent number: 7762616Abstract: A cross-member for a trailer frame and a frame incorporating the same. The cross-member extends between longitudinally aligned rails designed to pivotally support a dumping body thereon. The cross-member includes a cylindrical tube having a wall defining a bore therethrough. A planar member is received within the bore and is axially aligned therewith. The tube includes one or more axially aligned openings proximate a central region thereof. The planar member is disposed intermediate the openings and is aligned axially with the openings. The cross-member is substantially rigid under tension and at least a portion thereof is flexible under torsion.Type: GrantFiled: May 12, 2008Date of Patent: July 27, 2010Assignee: Sidump'r Trailer Company, Inc.Inventors: Fred P.

Patent number: 7740278Abstract: A steering gearbox mounting structure having an intermediate bracket mounts a steering gearbox for steering wheels of a vehicle on a subframe of the vehicle. The intermediate bracket has a breakable portion which breaks when a force greater than a predetermined force is applied to the breakable portion to provide an impact absorbing stroke of an engine of the vehicle. The breakable portion may have a thin portion such as a plate or a recess portion and is more breakable in the traveling direction than the width direction. First and second intermediate brackets may be used which include first and second kinds of breakable portions that are breakable in different modes, respectively.Type: GrantFiled: October 11, 2005Date of Patent: June 22, 2010Assignee: Honda Motor Co., Ltd.Inventors: Tsutomu Kakuta, Yasuhiro Tsutsui, Kazuhito Onoda, Hiroyuki Yoshida, Koji Nagata

Patent number: 7735870Abstract: A front structure 1 of a vehicle body has a shock absorber receiver 13 projecting forward from a dash panel 3, which is located at a position corresponding to a shock absorber 8 in a vehicle width direction and in a vehicle height direction. In the front structure 1 of the vehicle body, the shock absorber receiver 13 restricts backward movement of the shock absorber 8 upon a collision of a vehicle 2, so that a collision load acting on the shock absorber 8 can be efficiently dispersed to a framework of the vehicle body while being transmitted through the shock absorber receiver 13 to the dash panel 3. When the shock absorber 8 moves backward upon the collision of the vehicle 2, the shock absorber 8 comes into contact with the shock absorber receiver 13, and the distance becomes shorter between support points of the shock absorber 8 than before, so as to enhance flexural rigidity and reaction force.Type: GrantFiled: February 3, 2006Date of Patent: June 15, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Naoya Kosaka, Koji Tamakoshi
