Publication number: 20070158127Abstract: To readily remove on-vehicle components from a vehicle body, suitably reflecting the state of the vehicle or occupant in addition to the will of the operator. The safety confirmation device 11 determines whether or not to permit actuation of the separation actuator 13, that is, whether to set the switch 12 to the ON state to allow an electrical connection from the power supply 14 to the separation actuator 13, based on the signals input from the external input receiving portion 21, the occupant protection device 22, the status quantity sensor 23, and the input portion 24, and outputs a gate signal corresponding to this determination result to the switch 12. Electrification of the separation actuator 13 from the power supply 14 via the switch 12 releases the fixation of an on-vehicle component by disassembling the fixation member that fixes the on-vehicle component to the vehicle body.Type: ApplicationFiled: March 3, 2005Publication date: July 12, 2007Inventors: Katsuaki Taguchi, Yuta Urushiyama, Suguru Yoshida

Patent number: 6722729Abstract: An automobile front pillar (1; 40; 50) includes, at a portion thereof positioned closely to a passenger compartment (16) of an automobile (10), a weak portion (27b; 47b; 62) for initiating the buckling of the front pillar upon application of a shock to that part of the front pillar positioned remotely from the compartment. When an obstacle collides with the front pillar portion positioned remotely from the compartment, the weak portion collapses by the resulting collision shock to cause the front pillar to buckle. The collision shock is partly absorbed by the buckling front pillar, whereby the shock applied to the obstacle is significantly damped.Type: GrantFiled: December 30, 1999Date of Patent: April 20, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Suguru Yoshida, Hiroyuki Saegusa, Munehiro Mouri

Patent number: 6412581Abstract: A radiator mounting structure which has a front grill located in front of a radiator and provided with a projection extending toward the radiator. When a hood collides with an obstacle M and is deformed, the deformation causes the front grill to move rearward whereby the radiator is urged rearward of a vehicle body to tilt in the same direction. Thus, the hood is sufficiently deformable to thereby sufficiently alleviate an impact shock to be applied to the obstacle within a limited space.Type: GrantFiled: November 30, 2000Date of Patent: July 2, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Koji Enomoto, Suguru Yoshida

Strength optimization by an alloy that elevates hardenability, texture refinement obtained by fine dispersion of Ti oxides and TiN owing to Ti addition, precipitation strengthening by Cu addition, and formation of a fine bainite texture by temperature-controlled rolling, cooling control and the like enable a high-strength, high-toughness rolled steel shape of high-strength and excellent toughness having mechanical properties of a tensile strength of not less than 590 MPa, a yield strength or 0.2% proof strength of not less than 440 MPa and a Charpy impact absorption energy at 0° C. of not less than 47 J, and method of producing the same.Type: GrantFiled: March 30, 2000Date of Patent: April 2, 2002Assignee: Nippon Steel CorporationInventors: Kouichi Yamamoto, Hironori Satoh, Suguru Yoshida, Hirokazu Sugiyama, Hiroyuki Hasegawa

Patent number: 6340200Abstract: A pillar outer of a front pillar of an automotive vehicle comprises a stiffener and a flange portion connecting to a pillar inner. A peripheral portion of a windshield is fixed to a front face (a face orienting outwardly of the vehicle) of the flange portion via a plastically deformable member which can be deformed easily and plastically when a load is applied thereto in a longitudinal direction of the vehicle body. When an impact generated when an obstacle comes to interfere with the windshield is transmitted to the plastically deformable member, the plastically deformable member is easily press collapsed by the load, and the impact that is to be received by the windshield and the obstacle can be absorbed through the impact absorbing action. In addition, since the front face of the peripheral portion of the windshield is disposed flush with an outer wall portion of the pillar outer, a connecting portion between the two members is made flush with those members to thereby reduce the air drag thereat.Type: GrantFiled: November 14, 2000Date of Patent: January 22, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kouji Enomoto, Suguru Yoshida

Patent number: 6340203Abstract: An outer panel is made thinner than an inner panel, and a rear face facing a front door is folded so as to form a valley groove hollowed toward the interior of a tube constituted by true outer panel and the inner panel, whereby when a large magnitude of external force is applied to a front face in a rear ward direction, the outer panel is allowed to be deformed more largely than the inner panel to thereby collapse the valley groove, whereby the rearward travel of the rear face can be reduced.Type: GrantFiled: December 4, 2000Date of Patent: January 22, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kouji Enomoto, Suguru Yoshida

Publication number: 20010038227Abstract: An automotive vehicle in which a door hinge 64 of a front door 15 can forcibly be moved transversely outwardly of the vehicle, the automotive vehicle comprising an acceleration sensor 57 for detecting an impact applied to a front pillar and a door moving mechanism 52 for forcibly moving the door hinge 64 transversely outwardly of the vehicle, whereby the front door 15 is constructed to be moved transversely outwardly of the vehicle. In the event that an impact is applied to a front pillar, a front door can forcibly be moved transversely outwardly of an automotive vehicle on a side where the door hinge is provided, and in a case where the hinge is disposed in the vicinity of the front pillar, the transversely outward movement of the front door can be made large, whereby the interference of the front pillar with the front door can positively be prevented. Consequently, since the deformation of the front pillar cannot be prevented, the impact applied to the front pillar can effectively be absorbed and reduced.Type: ApplicationFiled: December 4, 2000Publication date: November 8, 2001Applicant: Honda Giken Kogyo Kabushiki KaishaInventors: Kouji Enomoto, Suguru Yoshida

Patent number: 5716155Abstract: The present invention relates to a T-shaped connection frame for connecting car frames, in which a first member is connected to a second member via a joint member to form a "T." The joint member is formed by symmetrically dividing a rectangular tube between its two latch teeth located at the upper-center and lower-center inner walls. The rectangular tube also has protrusions at the left and right exterior walls. The joint member divided in this way has the latch teeth at the upper and lower tips of the mouth formed by the division and has the protrusion situated opposite the mouth so that the first member can be snapped on easily to this mouth and the second member can be attached to the protrusion at the opposite side. This structural arrangement makes the positioning of the frames very simple, obviates a make-shift attachment, and, at the same time, reduces the number of operation steps.Type: GrantFiled: September 15, 1994Date of Patent: February 10, 1998Assignees: Honda Giken Kogyo Kabushiki Kaisha, Nippon Light Metal Co., Ltd.Inventors: Suguru Yoshida, Kohki Sugawara, Masakazu Sato, Mituo Tuge, Harumichi Hino, Keiichi Sugiyama, Shigeru Kohmura
