  • Publication number: 20160258511
    Abstract: A multistage transmission device includes a plurality of driving gears provided in a countershaft, a plurality of driven gears meshing with the driving gears, respectively, dog rings that switch mechanical connection or disconnection between the drive shaft and each of the driven gears, and one-way clutches arranged between the countershaft and the driving gears. The one-way clutches transmit rotation of the countershaft to the driving gears when the rotation of the countershaft is faster than the rotation of the driving gears.

  • Patent number: 9428139
    Abstract: An airbag for an airbag device for a front passenger seat is housed in a housing in the shape of a folded-up body in front of a front passenger seat. The airbag includes a main bag section that includes at the rear plane as deployed a front-collision arresting plane for catching a passenger as moves forward and an auxiliary bag section that protrudes rearward out of the front-collision arresting plane. The lateral of the auxiliary bag section facing towards the front-collision arresting plane serves as an oblique-collision arresting plane for catching the passenger as moves diagonally forward, The folded-up body of the airbag includes a means for temporarily jointing the auxiliary bag section in a folded up configuration to the main bag section and preventing the auxiliary bag section from protruding out of the front-collision arresting plane in an initial stage of airbag deployment.

  • Publication number: 20160207490
    Abstract: An airbag includes on the rear plane a passenger protection portion for protecting a front seat passenger. The passenger protection portion includes a front-collision arresting plane for protecting a head of the passenger as he moves forward in the event of a frontal collision of the vehicle and an oblique-collision arresting plane that is disposed at least either on the left or on the right of the front-collision arresting plane in such a manner as to protrude rearward out of the front-collision arresting plane for protecting the head of the passenger as he moves diagonally forward in the event of an oblique or offset collision of the vehicle. The passenger protection portion further includes an arresting recess that is disposed between the front-collision arresting plane and oblique-collision arresting plane in such a manner as to be sunken forward for receiving and arresting the head of the passenger.

  • Patent number: 9358945
    Abstract: An airbag housed in the housing and inflatable with an inflation gas for deployment rearward in order to protect a passenger in a front passenger seat. The airbag includes a main bag section that includes at its rear surface a front-collision arresting plane for catching the passenger upon a frontal collision, and an auxiliary bag section that includes an oblique-collision arresting section protruding rearward relative to the main bag section. The oblique-collision arresting section includes on its lateral an oblique-collision arresting plane for catching a head of the passenger upon an oblique collision. The oblique-collision arresting section is a high-pressure section which has a higher internal pressure than the main bag section when inflated. The airbag further includes in a front region of the auxiliary bag section a low-pressure section that is in gas communication with the main bag section and partitioned from the high-pressure section by a partition wall.

  • Patent number: 9290149
    Abstract: An airbag apparatus for a front passenger seat includes an airbag inflatable into a generally square conical contour whose top is deployable at the front end. The airbag is mounted on a case together with an inflator by the periphery of a gas inlet port which is located proximate the front end of the airbag. The airbag includes in a passenger side wall a recessed area that is sunken forward and extends vertically generally at airbag inflation. A seam that joints peripheral edges of a base material of the circumferential wall together extends forward from the recessed area. The seam is slanted off a front and rear direction such that the front end of the seam is directed toward either left or right when the airbag at full inflation is viewed from an up and down direction.

  • Patent number: 9278660
    Abstract: A front passenger seat airbag includes a support inflation portion that protrudes downwards from a portion of the airbag, which is positioned on a rear side of a gas inlet port when the airbag is completely inflated, that is in contact with a rear region of an accommodating portion of an instrument panel for accommodation of the airbag, and that is supported by the instrument panel. The support inflation portion is formed by joining together respective lower edges of support inflation configuration portions of outer left and right panels, by joining respective upper edges of the support inflation configuration portions with portions of corresponding outer circumferential edges of outer left panel and outer right panel main bodies, which are positioned in front of respective outer joining portions, and by respectively joining rear edges of the support inflation configuration portions with corresponding front lower edges of inner left and right panels.
