Patent number: 9533648Abstract: In a vehicle far side airbag device, a far side airbag is fixed to a seatback frame using stud bolts of an inflator. The far side airbag includes a bag portion at a face opposite a side face of the seatback frame. A support plate is retained in the bag portion and is fixed to the seatback frame using the stud bolts. The support plate is formed to be longer to both sides in a vehicle vertical direction than the inflator, and is engaged with the seatback frame at the vehicle upper side relative to the inflator. During inflation and expansion of the far side airbag, the support plate supports the far side airbag at both sides in the vehicle vertical direction of the inflator.Type: GrantFiled: November 27, 2015Date of Patent: January 3, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yusuke Fujiwara

Patent number: 9533605Abstract: In a vehicle side airbag device, when inflator operates, gas is supplied to left and right chambers of rear bag portion, and gas is supplied from communication opening through between a left and right side partitioning portions directly into a front bag portion. When inflation and expansion of the chambers are completed, the left and ride side partitioning portions are pushed against one another by internal pressures of the chambers, and the communication opening is closed-off. A valley, that is recessed toward a vehicle rear side, is formed at a front surface of the rear bag portion. At a time when the rear bag portion interferes with a vehicle occupant who is at an improper position, this valley is expanded due to the left and right chambers moving apart from one another in a vehicle left-right direction.Type: GrantFiled: July 30, 2014Date of Patent: January 3, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yusuke Fujiwara

Publication number: 20160368449Abstract: In the side airbag device, in an inflation and deployment state of the side airbag, a tension cloth extendingly disposed across between a front-rear partition and a rear end of the rear bag section is stretched, thereby restricting inflation in the vehicle front-rear direction of the rear bag section. An inflating width in a vehicle width direction of the rear bag section can be increased without significantly changing a position in the vehicle front-rear direction of the front-rear partition. In a flat developed state of the side airbag, the tension cloth is extendingly disposed across between the front-rear partition so folded into two as to protrude toward the rear bag section, and the rear end of the rear bag section. Accordingly, dimensions of each component can be so defined as to cause no redundancy in the rear bag section in the flat developed state, thus compactly folding the side airbag.Type: ApplicationFiled: June 6, 2014Publication date: December 22, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yusuke FUJIWARA

Publication number: 20160264091Abstract: To contribute to stabilizing the restraining of a head portion. When an air bag inflates and expands in a side airbag device for a vehicle, a rear bag portion accommodating an inflator inflates and expands earlier than and at a higher pressure than a front bag portion. The front bag portion, that is low pressure and inflates and expands later, can be supported by the rear bag portion that is high pressure, and the front bag portion does not shake greatly. Moreover, the flow of gas from the rear bag portion that is high pressure to the front bag portion that is low pressure can be regulated by the upper and lower communication ports formed in a tether. Due to the above, the expansion behavior of the front bag portion can be stabilized, which can therefore contribute to the restraining of the head portion by the front bag portion.Type: ApplicationFiled: August 25, 2014Publication date: September 15, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yusuke FUJIWARA

Publication number: 20160159313Abstract: Influence from a rear bag section is prevented or suppressed from being applied to an occupant out of position. In a state in which a side airbag inflates and deploys frontward of a side support section of a seat back, a front-rear partition cloth that partitions a bag body into a front bag section and a rear bag section brings an intermediate portion in a vehicle width direction of a front surface of the rear bag section to be recessed toward a vehicle rearward direction so as to be a valley-shaped recessed portion. Through this, even if the side airbag inflates and deploys while the occupant is located frontward of the side support section, it is possible to prevent or suppress influence from the rear bag section to this occupant.Type: ApplicationFiled: June 10, 2014Publication date: June 9, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yusuke FUJIWARA
