Patent number: 8015906Abstract: An actuator includes a piston having an actuating pin, a squib, and a cylinder case. The cylinder case has a peripheral wall part that covers the circumference of the piston and a ceiling wall part having a through hole which allows an actuating pin to protrude from the through hole. The actuator is configured to make the a piston move backward along with the actuating pin by ejecting a driving gas generated from the squib to a space between the ceiling wall part and the piston during actuation. A sealing ring which is relatively movable with respect to the actuating pin while maintaining the state of sealing up a gap between the actuating pin and the through hole, is provided at an inner face side of the ceiling wall part.Type: GrantFiled: June 4, 2009Date of Patent: September 13, 2011Assignee: Toyoda Gosei Co., Ltd.Inventors: Shun Ito, Michihisa Asaoka, Naohiko Ishiguro

Patent number: 7762584Abstract: An actuator which has an operating pin of the invention includes a piston which has an operating pin, a squib, and a cylinder case for holding the piston, in which the piston is moved rearward along with the operating pin by a driving gas generated injected from the squib into the cylinder case. A cap portion for covering the side of the squib with a gas injection port comprises a cylindrical side portion and a front end wall portion, and the operating pin is projected from the center of this front end wall portion. The cap portion is arranged with injection holes through which the driving gas is injected. Forward movement of the piston before the actuator is operated is restricted by the front end wall portion of the cylinder case coming into contact with the ceiling wall portion of the cylinder case.Type: GrantFiled: September 9, 2008Date of Patent: July 27, 2010Assignee: Toyoda Gosei Co., Ltd.Inventors: Bunpei Morita, Naohiko Ishiguro, Michihisa Asaoka, Shun Ito

Patent number: 7708307Abstract: A method for protecting an occupant seated on a seat of a vehicle in a side collision of the vehicle is disclosed. In the method, the lumbar region of the occupant is retained in a section that corresponds to the pelvis rearward of the acetabulum in the skeletal structure of the occupant by using an impact absorbing member. Specifically, the lumbar region of the occupant is retained in a section that corresponds to an ilium in the skeletal structure of the occupant. In a side collision of the vehicle, the impact absorbing member initially contacts the lumbar region in a section corresponding to the ilium.Type: GrantFiled: May 25, 2006Date of Patent: May 4, 2010Assignee: Toyoda Gosei Co., Ltd.Inventors: Hitoshi Ida, Michihisa Asaoka, Michio Inoue

Publication number: 20080082236Abstract: The airbag apparatus includes an inflator supplying inflation gas to an airbag under control of a control device. The inflator has two modes of operation; a rapid discharge mode where the inflator discharges a great amount of inflation gas and a slow discharge mode where the amount of substance of inflation gas supplied into the airbag per unit time is less than in the rapid discharge mode. The airbag apparatus includes means for reducing the resistance which the airbag encounters upon protruding from the housing under control of the control device. The means assist the airbag with protrusion from the housing when the inflator operates in the slow discharge mode.Type: ApplicationFiled: September 28, 2007Publication date: April 3, 2008Applicant: TOYODA GOSEI CO., LTD.Inventor: Michihisa Asaoka
