Patent number: 8186472Abstract: A pedestrian protection airbag device is provided in which an airbag (34) having a closed cross section is formed by inflating and deploying a front outer panel (16) and a front inner panel (18) of a front pillar (15) by means of high pressure gas generated by an inflator (26). This enables the head of a pedestrian to be protected from an impact due to collision with the front pillar (15). Furthermore, since impact absorption performance is exhibited by plastic deformation of the deployed airbag (34), as long as deployment of the airbag (34) is completed before restraining the pedestrian, it is unnecessary to subsequently control the internal pressure of the airbag (34), and it becomes possible for an effective impact absorption performance to always be exhibited regardless of the vehicle speed at the time of collision or the physique of the pedestrian while simplifying the specification of the inflator (26) and reducing the cost.Type: GrantFiled: November 18, 2008Date of Patent: May 29, 2012Assignee: Honda Motor Co., Ltd.Inventors: Yutaka Okamoto, Yuji Kikuchi, Koichi Kamiji

Method for setting inner pressure of vehicular external airbag, and vehicular external airbag system
Patent number: 7211752Abstract: When a small-size dummy has collided against a vehicle and once the head of the small-size dummy hits the deployed external airbag at a pre-determined velocity, the inner pressure of the deployed external airbag is set to a characteristic such that the inner pressure takes a predetermined maximum level value capable of not only preventing the dummy from bouncing off the airbag but also preventing the head of the dummy from hitting the bottom of the airbag. When a medium-size dummy has collided against the vehicle, the inner pressure of the deployed external airbag is set to a characteristic such that the inner pressure decreases away from the maximum level value at a predetermined decrease rate to prevent the medium-size dummy from bouncing off the airbag.Type: GrantFiled: January 24, 2006Date of Patent: May 1, 2007Assignee: Honda Motor Co., Ltd.Inventors: Yutaka Okamoto, Yuji Kikuchi, Koichi Kamiji -

Patent number: 6474686Abstract: A folded-up air bag is accommodated in a module cover of a steering wheel, and a peripheral edge of an opening in the air bag is fixed to a retainer supporting an inflator. The folded-up air bag is covered from a rear side of a vehicle to a front side of the vehicle by a deployment-limiting sheet disposed along an inner surface of the module cover and fixed at one end thereof to the retainer. The deployment-limiting sheet is longer than a length of an inner periphery of the module cover in a longitudinal direction of the vehicle body. Thus, it is possible to inhibit the air bag from being expanded rearwards of the vehicle body at an initial stage of deployment by the deployment-limiting sheet, thereby avoiding the early interference with an occupant.Type: GrantFiled: May 17, 2001Date of Patent: November 5, 2002Assignee: HOnda Giken Kogyo Kabushiki KaishaInventors: Hitoshi Higuchi, Takeru Otsuka, Koichi Kamiji, Nobuyuki Kawamura, Masae Sato, Kenichi Saito

Patent number: 6424268Abstract: A sheet-shaped sensor body includes a first protective layer formed of a resist paste layer, an antenna film formed of a PET film, a first conductive layer formed of a silver layer, a second conductive layer formed of a carbon layer, a second protective layer formed of a resist paste layer and a hot-melt film, which are laminated one on another in sequence. When the hot-melt film of the sensor body is brought into abutment against a front surface of a wadding previously adhered to a pad of a seat back and is then heat-pressed, the sensor body is fixed firmly and reliably to the wadding by an adhesive force generated by the melted hot-melt film once it again cools and solidified. Thus, the sensor of an occupant detecting system for detecting the physical constitution and the attitude of an occupant sitting on a seat can be fixed easily and reliably to the seat back.Type: GrantFiled: September 6, 2000Date of Patent: July 23, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kazutomo Isonaga, Tsutomu Fukui, Nobuhiro Koyota, Naoto Ishii, Koichi Kamiji

Patent number: 6286863Abstract: An inflater of an air bag device is provided which includes a first combustor, providing an output having a peak value Ma and a second combustor, providing an output having a peak value Mb (wherein Mb<Ma). After ignition of the first combustor, the second combustor is ignited with a time lag. The igniting timing of the second combustor is set later than a time point at which the peak value of the sum of the outputs from the first and second combustors can be equalized to the peak value Ma of the output from the first combustor, and earlier-than a time point at which the combustion of the first combustor is finished. Thus, it is possible to prevent the sudden deployment of the air bag to moderate the shock applied to the occupant, while ensuring the smooth deployment of the air bag.Type: GrantFiled: December 2, 1998Date of Patent: September 11, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Koichi Kamiji, Hitoshi Higuchi, Makoto Nagai

Patent number: 6169947Abstract: If a seat belt is not fastened, then a first switch is turned on and a second switch is turned off, and a fastened status detector outputs an impact decision level signal to a switch, which selects a signal from a first impact decision level output unit. Thus, when the speed of a motor vehicle is about 16 km/h or higher immediately prior to a collision, an air bag is inflated upon the collision. If the seat belt is fastened, then the first switch is turned off and the second switch is turned on, and the fastened status detector outputs an impact decision level signal, selecting a signal from a second impact decision level output unit. Thus, when the speed of the motor vehicle is about 24 km/h or higher immediately prior to a collision, the air bag is inflated upon the collision.Type: GrantFiled: November 18, 1998Date of Patent: January 2, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tsutomu Fukui, Nobuhiro Koyota, Kazutomo Isonaga, Koichi Kamiji

Patent number: 5080188Abstract: A mounting structure for a vehicle deceleration sensor, comprising a deceleration sensor mounted on a part of a vehicle body where a longitudinal end of a front side member extending along a fore-and-aft direction of the vehicle body on one side thereof and a bulkhead separating a passenger compartment from a front part of the vehicle body are joined together with a part of the deceleration sensor protruding into the hollow interior of the front side member. Thus, a deceleration resulting from a vehicle crash is quickly transmitted to the deceleration sensor through the front side member, and the deceleration sensor is protected from adverse environmental effects as it may be located in the interior of the front side member.Type: GrantFiled: January 23, 1990Date of Patent: January 14, 1992Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Hisakazu Okuhara, Koichi Kamiji, Masao Mochiji, Junichi Fukuda

Patent number: 5080395Abstract: An improved occupant protective system for an automotive vehicle includes an occupant-protecting member, an acceleration sensor for detecting acceleration of the vehicle, an actuator for actuating the occupant-protecting member, and a monitoring device for monitoring potentials of two signal lines connected respectively to the opposite ends of the actuator and having portions thereof extending substantially parallel with each other. One of the signal lines is connected between the acceleration sensor and the actuator. When the vehicle undergoes acceleration having a magnitude greater than a predetermined value, the acceleration sensor operates to cause an increased amount of electric current to flow through the two signal lines to thereby cause the actuator to operate. The improved occupant protective system includes a monitoring line extending parallel with the two signal lines along the portions of the two signal lines extending substantially parallel with each other.Type: GrantFiled: September 10, 1990Date of Patent: January 14, 1992Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Makie Morota, Koichi Kamiji
