Patent number: 6938715Abstract: If a control device determines that a collision during a vehicle run has been detected on the basis of a combination of an output signal of a sensor and a vehicle speed signal, an inflator is actuated so as to inflate and deploy an air bag body disposed in an apron upper member. When inflated and deployed, the air bag body raises a longitudinal-direction central portion of a hood. At this time, the longitudinal-direction central portion of the hood bends with a depression serving as an origin of bending.Type: GrantFiled: December 26, 2002Date of Patent: September 6, 2005Assignee: Toyota Jidosha Kabushiki KaishaInventors: Makoto Hamada, Hiroyuki Takahashi

Patent number: 6397688Abstract: A seating load detecting device in which a lower arm for supporting a seat cushion and a seat back is coupled with an upper rail by a front bracket and a rear bracket. A distortion gage is attached to the bracket. The bracket comprises a curved portion of a U-shape or V-shape. The lower arm and the upper rail are coupled to each other with the direction orthogonal to two opposing legs of the curved portion being vertical. The distortion gage has a total of four distortion detecting elements G11 to G22 distributed in a matrix distribution, two attached in the front and back directional plane of the legs and two attached in the width directional plane of the legs. Due to the Wheatstone bridge connection line of these elements, high gain of a seating load detection voltage e with respect to the amount in change of the vertical load Fv can be obtained.Type: GrantFiled: September 20, 2000Date of Patent: June 4, 2002Assignees: Aisin Seiki Kabushiki Kaisha, Kyowa Electronic Instruments Co., Ltd.Inventors: Kazunori Sakamoto, Yoshisaburo Todo, Makoto Hamada, Osamu Fujimoto

Patent number: 6398258Abstract: An air bag apparatus for a passenger seat has reduced deploying speed and reduces the impact of the air bag on an occupant moving forward at the time of a crash of a vehicle. A gas generator is disposed in a case of the air bag apparatus, extending in a fore-to-aft direction relative to the vehicle. The gas generator case contains a cylindrical inflator extending in the fore-to-aft direction. An air bag is disposed in the apparatus case, folded in a predetermined manner. An inner bag for controlling gas flow is disposed in the air bag, folded in a predetermined manner. An auxiliary inner bag is sewed to an outside surface of a bag of the inner bag. When the inner bag is inflated and deployed, the bag of the inner bag presses a portion of the air bag against the windshield, and the auxiliary inner bag presses another portion of the air bag against the instrument panel.Type: GrantFiled: February 8, 2001Date of Patent: June 4, 2002Assignee: Toyota Jidosha Kabushiki KaishaInventors: Makoto Hamada, Osamu Fukawatase, Koushi Kumagai

Patent number: 6371513Abstract: A side airbag is housed together with an inflator containing a high pressure gas as a module in a door-side side portion of a seat. The side airbag is deployed into a space between the door and an occupant sitting in the seat, on the basis of an instruction signal from an airbag control device. An occupant sensor is disposed at a position that is located in an upper portion of a seatback of the seat and shifted from a center of the seatback with respect to directions of a width thereof toward a vehicle body center. By using the occupant sensor, it is determined whether an occupant is present at a seat of a vehicle, excluding a case where an occupant having a constitution smaller than a predetermined constitution is leaning against the side vehicle body portion. The airbag control device permits operation of the side airbag if presence of an occupant is detected by the occupant sensor. The control device prohibits operation of the side airbag if absence of an occupant is detected by the occupant sensor.Type: GrantFiled: August 31, 1999Date of Patent: April 16, 2002Assignee: Toyota Jidosha Kabushiki KaishaInventors: Osamu Fujimoto, Makoto Hamada

Patent number: 6367837Abstract: A seated-state detection sensor is disposed in a seat portion of a seat cushion of a passenger seat. The seated-state detection sensor is divided into three parts, that is, a first seated-state detection sensor, a second seated-state detection sensor and a third seated-state detection sensor, which are arranged in this order from the rear side of the vehicle. The first seated-state detection sensor and the second seated-state detection sensor are designed to determine whether or not there is a passenger seated. The second seated-state detection sensor and the third seated-state detection sensor are designed to detect forward displacement of the passenger.Type: GrantFiled: March 17, 2000Date of Patent: April 9, 2002Assignee: Toyota Jidosha Kabushiki KaishaInventors: Makoto Hamada, Hiroshi Uenaka, Seiji Yamashita, Osamu Fujimoto

Patent number: 6356200Abstract: A sensor attaching portion of an upper rail and a sensor attaching portion of a cushion frame are provided with a sensor attaching plate having a sensor disposed thereon. The upper rail and the seat cushion frame are connected with a bracket at a position facing the sensor attaching plate. When the passenger sits on the seat, the seat cushion frame moves down and a bent portion of the bracket is pressed and deformed downwards. At this time, the center in the vertical direction of the sensor attaching plate is bent outward in the lateral direction of the seat. The sensor serves to detect the generated deformation.Type: GrantFiled: January 14, 2000Date of Patent: March 12, 2002Assignee: Toyota Jidosha Kabushiki KaishaInventors: Makoto Hamada, Makoto Sekizuka, Osamu Fukawatase, Osamu Fujimoto

Patent number: 6186538Abstract: An air bag control system for passenger seat has a seated-state detection sensor provided in a seat, a proximity sensor that detects an object near an air bag apparatus, and an impact sensor that detects a deceleration at the time of an impact. If there is no detection made by the proximity sensor for a predetermined length of time after the seated-state detection sensor detects the seating of an occupant, a control device keeps the air bag apparatus in an operable state after elapse of the predetermined length of time. If there is no detection made by the proximity sensor for the predetermined length of time after the seated-state detection sensor makes detection, the control device ignores an on-state of the proximity sensor or a signal from the proximity sensor, and keeps the air bag apparatus in the operable state.Type: GrantFiled: March 30, 1998Date of Patent: February 13, 2001Assignee: Toyota Jidosha Kabushiki KaishaInventors: Makoto Hamada, Akihiro Osanai, Yoshiaki Inoue, Minoru Izawa
