Patent number: 8480122Abstract: An airbag device equipped with an airbag having a reduced volume. An airbag inflated and expanded, by supplied gas, from a state folded in the rear of an instrument panel with respect to the vehicle's front-rear direction has an outer bag for restraining the upper body of a vehicle occupant from the front side in the vehicle's front-rear direction and also has a reaction force support tube inflated and expanded, by supplied gas, at the front on the inner side of the outer airbag. An inflator supplies gas to each of the outer bag and the reaction force support tube. When the outer bag restrains the upper body of the vehicle occupant, gas discharge from the reaction force support tube is suppressed by a one-way valve and the pressure in the reaction force support tube is maintained at a pressure higher than the pressure in the outer bag.Type: GrantFiled: July 24, 2009Date of Patent: July 9, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Koji Ohara

Patent number: 8233561Abstract: Data comprising a pulse signal is divided into predetermined data segments. The number of pulse-signal fluctuations in the data segment is counted. A transmitter transmits the unchanged data to a receiving portion in a case where the number of pulse-signal fluctuations does not exceed a predetermined number. On the other hand, in a case where the number of pulse-signal fluctuations exceeds the predetermined number, the pulse signal is converted so as to be unchanged at the fluctuation of the pulse signal but to be fluctuated when the pulse signal does not fluctuate. Then, the transmitter transmits the converted pulse signal to the receiving portion wherein only the converted pulse signal is converted to the original pulse signal.Type: GrantFiled: January 16, 2008Date of Patent: July 31, 2012Assignee: Konica Minolta Business Technologies, Inc.Inventors: Takeshi Nomura, Koji Ohara, Masao Kondo, Shinichi Yabuki

Patent number: 8215665Abstract: The present invention obtains an airbag device that can effectively protect an upper body and knees of a passenger by a simple airbag structure. An airbag that structures an airbag device for a passenger's seat has a main bag that restrains an upper body of a vehicle passenger from a front side in a vehicle longitudinal direction, a sub-bag that has a smaller volume than the main bag and that restrains knees of the passenger from the front side in the vehicle longitudinal direction, and an inner tube that is folded-up together with the main bag and the sub-bag and is inflated and expanded within the airbag by a gas supply from an inflator. The inner tube directly supplies gas of the inflator to the main bag and the sub-bag respectively. A check valve is provided at a gas exit that communicates the inner tube with the sub-bag.Type: GrantFiled: August 1, 2011Date of Patent: July 10, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koji Ohara, Takashi Sasaki
