Patent number: 9211862Abstract: An inflation portion of an airbag, which is inflated by inflation gas, is partitioned into an upstream inflation portion and a downstream inflation portion via a partition member. When being tensioned in a planar manner, the partition member has a length in a longitudinal direction that is longer than a length in a transverse direction perpendicular to the longitudinal direction. A pressure regulating valve that is closed at an early stage of a supply period of the inflation gas to the inflation portion and is opened from the middle of the supply period includes a slit-like inner opening that is provided on the partition member and extends in the transverse direction and a pair of valve body portions that are provided around the inner opening and are selectively positioned close to and separated from each other.Type: GrantFiled: July 29, 2014Date of Patent: December 15, 2015Assignee: TOYODA GOSEI CO., LTD.Inventors: Koji Shibayama, Kensaku Honda, Yuji Sato, Michiyasu Ito, Masashi Hotta, Masashi Aoki, Daisuke Yamamura

Patent number: 7909359Abstract: A side airbag apparatus is provided with an inflator, and an airbag. The airbag is stored in a vehicle seat, is inflated and deployed by gas from the inflator, breaks the vehicle seat so as to jump out, and is inflated and deployed between a body side portion of a vehicle and the vehicle seat. In this side airbag apparatus, a controller predicts a side collision of the vehicle, and makes the inflator start an actuation in advance of the side collision in response to the prediction. Further, in the airbag inflated and deployed in accordance with the actuation start of the inflator, a deploying speed of the airbag is lowered in comparison with the deploying speed at a time of starting the actuation of the inflator after the side collision, at least outside the vehicle seat.Type: GrantFiled: March 25, 2008Date of Patent: March 22, 2011Assignee: Toyoda Gosei Co., Ltd.Inventors: Michio Inoue, Takashi Naito, Yuji Sato, Daisuke Yamamura

Patent number: 7819421Abstract: A side airbag apparatus has an airbag assembly that protects a passenger seated on a seat in a passenger compartment by being inflated and deployed at a side wall portion of the passenger compartment corresponding to the seat in a collision of a vehicle. The airbag assembly includes a main airbag and an auxiliary airbag that inflate and deployed in a state arranged along a lateral direction of the vehicle. If the body size of the passenger is greater than or equal to a predetermined size, the main airbag is inflated and deployed and the auxiliary airbag is not inflated or deployed. If the body size of the passenger is smaller than the predetermined size, the main airbag and the auxiliary airbag are both inflated and deployed. Thus, in the latter case, the airbag assembly in the inflated and deployed state has a great thickness in the lateral direction of the vehicle compared to the case in which the body size of the passenger is greater than or equal to the predetermined size.Type: GrantFiled: March 19, 2008Date of Patent: October 26, 2010Assignee: Toyoda Gosei Co., Ltd.Inventors: Takashi Naito, Yuji Sato, Michio Inoue, Daisuke Yamamura

Publication number: 20080079249Abstract: A side airbag apparatus includes an inflator and an airbag that is inflated and deployed by gas generated by the inflator to protect an occupant seated on a seat. The airbag includes a lumbar region protecting section, which primarily protects the lumbar region of the occupant. Prior to the inflation and deployment, the airbag is accommodated in the backrest in a state where a part including the lumbar region protecting section is folded back in a direction toward the rear of the vehicle. This configuration prevents the inflation of the airbag from being hindered and allows the airbag to properly protect the lumbar region of the occupant.Type: ApplicationFiled: September 27, 2007Publication date: April 3, 2008Applicant: TOYODA GOSEI CO., LTD.Inventor: Daisuke Yamamura

Patent number: 7322606Abstract: An occupant protection apparatus includes a cover sheet adapted to be fed out from a peripheral edge of a window of a vehicle, when a pulling unit is activated, so as to cover the window. The pulling unit includes a pulling string having flexibility and a pulling device to which the pulling string is connected so as to be pulled thereby and which is disposed below the window. When the pulling device is activated, the pulling string is pulled such that a portion thereof which extends from a fixed end to where it is supported by a support member becomes a straight line while a portion thereof which is disposed along a lower edge portion of the peripheral edge of the window is caused to rise.Type: GrantFiled: November 2, 2006Date of Patent: January 29, 2008Assignee: Toyoda Gosei Co., Ltd.Inventors: Daisuke Yamamura, Michio Inoue
