Publication number: 20240123934Abstract: An airbag device includes an airbag that is supplied with gas generated by an inflator during a vehicle collision and that inflates and deploys from a rear side of a vehicle seat toward a front side via an upper side. In an inflated and deployed state, the airbag includes a pair of front-rear chambers extending in a seat front-rear direction via left and right sides of a head of a passenger, an airbag body that is in communication with the pair of front-rear chambers and that is disposed at a front side of the passenger between the pair of front-rear chambers, and a pair of rear tethers including one-end portions attached to the airbag body and other-end portions attached to a seatback of the vehicle seat. At least a rear tether on a side door side is configured so as to be releasable after a collision of the vehicle.Type: ApplicationFiled: September 13, 2023Publication date: April 18, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mitsuyoshi OHNO, Takeshi YAMAMOTO, Toshiki IWAMA, Yoshito KUSUHARA, Tsutomu ISHII

Publication number: 20240123936Abstract: An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction. Gas is supplied to the airbag main body via a communication hole positioned at a seat rear side of the connecting portion of the front-rear chamber that has inflated and deployed. Owing to inflation and deployment of the front-rear chamber, the airbag main body passes through a gap between a ceiling of the vehicle and the head from the seat rear side toward the seat front side, and thereafter, inflates and deploys toward the seat rear side.Type: ApplicationFiled: September 28, 2023Publication date: April 18, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mitsuyoshi OHNO, Takeshi YAMAMOTO, Toshiki IWAMA, Yoshito KUSUHARA, Tsutomu ISHII

Publication number: 20240123933Abstract: An airbag device includes an airbag that is supplied with gas during a vehicle collision, and that inflates and deploys from a rear side of a vehicle seat toward a front side via an upper side thereof. In an inflated and deployed state the airbag includes a pair of front-rear chambers extending in a front-rear direction via left and right sides of the head of a passenger, and an airbag body in communication with the pair of front-rear chambers, that is disposed at a front side of the passenger between the pair of front-rear chambers, and that is compression deformed in a state supported by the pair of front-rear chambers during restraint of the passenger. The airbag is configured such that entry of at least the head of the passenger into gaps between the front-rear chambers and the airbag body is suppressed during a latter half of restraining the passenger.Type: ApplicationFiled: September 13, 2023Publication date: April 18, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mitsuyoshi OHNO, Takeshi Yamamoto, Toshiki Iwama, Yoshito Kusuhara, Tsutomu Ishii

Publication number: 20240123935Abstract: An airbag device including an airbag that inflates and deploys from a seat rear side of a vehicle seat toward a seat front side via a seat upper side. In an inflated and deployed state, the airbag includes a pair of front-rear chambers extending in a front-rear direction via left and right sides of a head of a passenger, an airbag body that is in communication with the pair of front-rear chambers and that is disposed at a seat front side of the passenger between the pair of front-rear chambers, and a pair of rear tethers including one-end portions attached to the airbag body and other-end portions attached to a seatback. At a time of restraint of the passenger, the airbag body is pulled by the rear tethers obliquely rearward and downward such that the front-rear chambers press shoulders of the passenger from a seat upper side.Type: ApplicationFiled: September 13, 2023Publication date: April 18, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mitsuyoshi OHNO, Takeshi YAMAMOTO, Toshiki IWAMA, Yoshito KUSUHARA, Tsutomu ISHII

Publication number: 20240123940Abstract: An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction. The airbag main body inflates and deploys toward a side of the passenger at a seat rear side of the connecting portion, later than the front-rear chamber. The airbag main body has a downward-force applying portion that applies force directed toward a seat lower side to the airbag at a time when the passenger is restrained by the airbag.Type: ApplicationFiled: September 28, 2023Publication date: April 18, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mitsuyoshi OHNO, Takeshi YAMAMOTO, Toshiki IWAMA, Yoshito KUSUHARA, Tsutomu ISHII

Publication number: 20240123937Abstract: An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger seated in a vehicle seat and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction. The airbag main body inflates and deploys toward a side of the passenger at a seat rear side of the connecting portion, later than the front-rear chamber. At a time when the passenger is restrained, the airbag main body is compressed in a seat front-rear direction while stretching the front-rear chamber in the seat front-rear direction.Type: ApplicationFiled: October 11, 2023Publication date: April 18, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mitsuyoshi OHNO, Takeshi YAMAMOTO, Toshiki IWAMA, Yoshito KUSUHARA, Tsutomu ISHII

Patent number: 10758109Abstract: In a medical examination sight maintaining videoscope of the present invention, in a state where an examination attachment is attached, it becomes possible to position a scope tip-end section and an object to be examined in a positional relationship in which the scope tip-end section and the object to be examined are straightly aligned with a line of sight of the user. At this time, a monitor is situated at such a position that the user can look straight at the monitor and the line of sight of the user is avoided.Type: GrantFiled: January 29, 2019Date of Patent: September 1, 2020Assignee: MPI Inc.Inventor: Takeshi Iwama
