Publication number: 20180154857Abstract: An airbag device for a passenger seat is disclosed. The airbag includes a main section whose rear plane forms a front-collision arresting plane, and a sub section which is disposed on a side of the main section and includes a protruding region protruding farther rearward than the main section. The side plane of the protruding region forms an oblique-collision arresting plane. Between the front-collision- and oblique-collision arresting planes is an arresting recess denting forward. The airbag further internally includes a front-rear tether jointed to the front-collision arresting plane, and a recess-pulling tether jointed to the bottom of the arresting recess. The front-rear tether and recess-pulling tethers share a mounting base by which the tethers are mounted on an airbag case, and bifurcate from the mounting base. The front-rear tether extends from a rear edge of the mounting base, and the recess-pulling tether extends from an edge of the mounting base adjoining the front-rear tether.Type: ApplicationFiled: November 29, 2017Publication date: June 7, 2018Inventor: Ikuo YAMADA

Patent number: 9938881Abstract: A cooling water passage structure of internal combustion engine includes a cylinder-block-side cooling water passage, a cylinder-head-side cooling water passage, a heat exchanger, and cooling water passage pipes. The cylinder-block-side cooling water passage is formed inside a cylinder block of an engine to cause cooling water to flow through. The cylinder-head-side cooling water passage is formed inside a cylinder head to cause cooling water to flow through. The heat exchanger is configured to dissipate heat of cooling water to external air to decrease a temperature of the cooling water. The cooling water passage pipes couple the heat exchanger and the engine to exchange cooling water. The cylinder head includes a cooling water inlet. The cooling water passage pipe is coupled to the cooling water inlet. The cooling water from the heat exchanger flows into the cooling water inlet.Type: GrantFiled: March 2, 2016Date of Patent: April 10, 2018Assignee: SUZUKI MOTOR CORPORATIONInventor: Ikuo Yamada

Patent number: 9925948Abstract: An airbag is inflatable in such a manner as to separate a vehicle-side wall which is deployable towards a vehicle body structure and an occupant-side wall which is deployable towards an occupant for catching the occupant. The airbag is configured to be supported by the vehicle body structure on the vehicle-side wall when catching the occupant with the occupant-side wall. The airbag includes a recessed section on left and right sides of and in a vicinity of the center of the occupant-side wall and a tether that connects the bottom of the recessed section to the vehicle-side wall in order to form the recessed section. Opposing walls of the recessed section press each other in a separable fashion when the airbag is inflated. The tether allows gas communication between a central region of the airbag and a peripheral region of the airbag which surrounds the central region, inside the airbag.Type: GrantFiled: September 27, 2016Date of Patent: March 27, 2018Assignee: TOYODA GOSEI CO., LTD.Inventors: Masashi Hotta, Takashi Iida, Yuji Sato, Ikuo Yamada, Mikine Hayashi

Publication number: 20180022303Abstract: An airbag includes a main inflatable section which includes a front-collision arresting face at the rear plane as deployed, a protruding inflatable section which includes an oblique-collision arresting face, and an arresting recess formed between the front-collision arresting face and oblique-collision arresting face. The airbag internally includes a recess-pulling tether which joints the leading end of the arresting recess and a front end portion of the airbag as deployed, and a regulating tether which extends from the leading end of the arresting recess towards a far-side wall of the protruding inflatable section which is opposed to the oblique-collision arresting face. A joint position of the regulating tether to the far-side wall is such a position that would produce a pulling force which pulls the protruding inflatable section towards the rear plane of the main inflatable section when the leading end of the arresting recess moves forward at catching a passenger.Type: ApplicationFiled: July 12, 2017Publication date: January 25, 2018Inventor: Ikuo YAMADA
