  • Publication number: 20250067334
    Abstract: A planetary gear mechanism has a helical gear. A lubrication system for the planetary gear mechanism includes a first lubricating oil supply path, a second lubricating oil supply path, and a controller. The first lubricating oil supply path is disposed on one side of the helical gear in a direction along a rotation axis of the helical gear. The first lubricating oil supply path is formed toward a tooth surface of the helical gear. The second lubricating oil supply path is disposed on an other side of the helical gear. The second lubricating oil supply path is formed toward the tooth surface of the helical gear. The controller switches discharge of lubricating oil to the tooth surface of the helical gear between the first lubricating oil supply path and the second lubricating oil supply path based on a rotation direction of the helical gear.

  • Patent number: 9688229
    Abstract: An airbag of an airbag device for a driver seat has a front panel and a back panel. In the airbag having undergone spontaneous inflation, when a size between a securing position of the airbag to a retainer member and the most protruding portion of the airbag with respect to the securing position is set as 1, the most protruding portion by the back panel is located at a position spaced from the securing position by 0.5 or greater, a diameter of the inflated airbag of an opposing portion to an inner surface of the wheel is 0.6 to 1.2 times as large as an inner diameter of the wheel, and a diameter of the inflated airbag of a joint portion of the front panel and the back panel is greater than the diameter of the inflated airbag of the opposing portion to the inner surface of the wheel.

  • Patent number: 8528934
    Abstract: Closing movement of at least one of two or more air chambers is started at an early stage, and an inflated air chamber is tightly closed and maintained in an inflated state for a long time. Inside of an airbag is partitioned into air chambers, with a partitioning cloth, and a diffuser that stores a gas generator is disposed in the air chambers, through the partitioning cloth. Gas from a gas generator is rectified by the diffuser, and is supplied from outlet parts, into the air chambers, thereby inflating and deploying the air chambers. An occupant side base cloth, a semi-perimeter portion around the lower outlet part, is connected to a back-side base cloth of the airbag, and in accordance with an inflation of the lower air chamber, a tension is imposed on the occupant side base cloth from the back-side base cloth, thereby elongating the lower air chamber.
