  • Patent number: 9493058
    Abstract: A sunroof drain device includes a drain portion that includes a bottom wall, a first side wall that rises up in the height direction of the vehicle from an edge end of the bottom wall that is positioned on a side near the opening, and a second side wall that rises up higher than the first side wall in the height direction of the vehicle from an edge end of the bottom wall that is positioned on a side away from the opening. The sunroof drain device also includes a sawtooth-shaped portion that is provided protruding upward in the height direction of the vehicle on the bottom wall so as to extend along the boundary portion, with a surface that is on the side away from the opening being more gradually inclined than a surface that is on the side near the opening.

  • Patent number: 5198629
    Abstract: A horn switch for a steering wheel having an air bag device. The steering wheel includes a multilayer membrane switch as the horn switch in which spacers in one layer are not aligned with the spacers in the other layers. Accordingly, even when the membrane switch is depressed just over one of the spacers in one layer, the electrode plates in the other layers can make contact with each other. Thus the operable area of the membrane switch is enlarged. Further, the membrane switch is supported on its lower surface by a number of ribs which define a number of spaces between the pad lower surface and air bag device. As a result of this space, the operation on the membrane switch can be made resilient in spite of the provision of the air bag device directly under the steering wheel pad. Further, because each part of the pad separated by the air bag device upon impact, each part must be provided with a membrane switch.

  • Patent number: 5092628
    Abstract: An air bag apparatus is disclosed having a locking device which is adapted to prevent the inflation of a bag accommodated in an air bag body before the air bag body is mounted on a chassis, the bag being adapted to be inflated in front of a seat occupant when a predetermined acceleration has acted on the air bag body. This locking device is arranged such that an actuating member is driven by an operator's operation after mounting the air bag body on the chassis to release the locking device, thereby canceling a locked state and making the air bag body operable.

  • Patent number: 4995638
    Abstract: An air bag cover for covering an air bag in a folded state, the air bag being adapted to expand in front of a seat occupant at a sudden deceleration of the vehicle speed. The air bag cover includes a first thin-wall portion which is first broken by the expanding pressure at the time of the inflation of the air bag and a second thin-wall portion which is broken after the breakage of the first thin-walled portion has advanced. The first thin-walled portion and the second thin-walled portion are connected to each other in such a manner as to be substantially perpendicular to each other. A connecting portion between the two thin-walled portions has an even smaller thickness than the thicknesses of the two thin-walled portions, thereby permitting the breakage of the first thin-walled portion to advance smoothly to the second thin-walled portion.
