  • Patent number: 9283917
    Abstract: A curtain airbag device that can be applied to a small-width pillar. The curtain airbag device is accommodated in a region extending from at least an A-pillar to an upper portion of a window frame, and includes an airbag that is deployed in a curtain form near a side window of a vehicle interior in order to protect an occupant; and a gas generator that supplies inflation gas to the airbag. The accommodated airbag is formed in a rod shape by being folded in a roll form. When the airbag is accommodated, the airbag is partially compressed toward the center of the airbag at a narrow portion where an installation area of the A-pillar is narrow, in order to partially decrease a diameter of the airbag.

  • Patent number: 9283918
    Abstract: A curtain airbag capable for preventing occupant ejection from a vehicle, particularly in the vicinity of a rearmost seat, while reducing the output required of an inflator associated with the airbag. The curtain airbag is stored at an upper position on a side surface portion of the occupant compartment of the vehicle, so as to be inflated and deployed along the side surface portion. The curtain airbag includes an inflation region and a wide portion in the form of non-inflatable cloth. The wide portion is attached to a rear edge portion of the inflation region and also attached to at least one point of the vehicle rearward of a front-side pillar, the front-side pillar being located forward of rearmost side window. The wide portion has a shape that allows it to be strained, by the inflated and deployed inflation region, into a generally planar configuration over an assumed strike area of the rearmost side window.

  • Patent number: 9271554
    Abstract: An applicator including an applying part of a liquid absorber impregnated with an application liquid. An indicator portion having a jagged configuration that varies in reflectance of light depending on the quantity of the application liquid in the liquid absorber is formed adjacent to the liquid absorber, and the formed area of the indicator portion of an application liquid feeder can be visually observed from the outside so that the quantity of the application liquid can be displayed by the reflected light of indicator portion. The applicator allows a visual check on whether the application liquid is full or less when the applicator is unused or when the application liquid is decreased after use, from the change of the reflectance of light in indicator. The applicator permits easy confirmation of the liquid quantity and can easily avoid liquid blobbing.

  • Patent number: 9027225
    Abstract: A one-piece back frame including an upper portion, a lower portion and a pair of vertical portions. The upper portion includes a first flange bent downwardly and a second flange bent upwardly to enclose the upper portion. The first and second flanges are brazed or welded to one another, which has the effect of strengthening the upper portion of the back frame and increasing its resistance to forces and moments during front or rear impact. Additionally, a pair of tubes extend through and are connected to upper portion. The tubes are designed for receiving a head restraint, but also serve the additional purpose of further strengthening the upper portion to increase its resistance to forces and moments during front or rear impacts.
