  • Publication number: 20210114520
    Abstract: A vehicle body motion informing device includes a vehicular interior part that configures an interior surface of a vehicular compartment of a vehicle, a lighting device mounted on a vehicular exterior side of the vehicular interior part and exiting light to a vehicular compartment, a control unit that receives an information signal relating to the motion of the vehicle body and controls the lighting device to exit light according to the information to inform the vehicle occupant of the motion of the vehicle body, and a surface member having semi-transmissivity and disposed to cover at least a lighting portion included in the vehicular interior part and a surrounding portion of the vehicular interior part. The lighting portion overlaps the lighting device and the light from the lighting device passes through the lighting portion to the vehicular compartment and the surrounding portion is near the lighting portion.

  • Patent number: 10906460
    Abstract: There is provided a skin material for vehicle interior, which is woven from a side emission type optical fiber and a synthetic resin fiber, forms a design surface in a vehicle compartment and functions as an illumination. The skin material for vehicle interior is a skin material 10 for vehicle interior including a woven fabric woven by using a synthetic resin fiber and a side emission type optical fiber as warp or weft, wherein the ratio (dS/df) of the fineness (dS) of the synthetic resin fiber to the fineness (df) of the side emission type optical fiber ranges from 1.5 to 7.0. When the synthetic resin fiber is a multifilament 11, the ratio (dS1/df) of the fineness (dS1) thereof to the fineness (df) of the side emission type optical fiber 3 ranges from 2.0 to 7.0. Also, when the synthetic resin fiber is a monofilament, the ratio (dS2/df) of the fineness (dS2) thereof to the fineness (df) of the side emission type optical fiber ranges from 1.5 to 6.0.

  • Patent number: 10054729
    Abstract: An illumination apparatus includes a woven fabric in which optical fibers are woven as a constituent yarn and a light source. The illumination apparatus makes light delivered from the light source incident upon the end surfaces on one end side of the optical fibers and emits the light at least from the end surfaces on the other end side of the optical fibers for illumination. The other end side of the optical fibers is exposed from the woven fabric to constitute exposed parts, and the end parts of a plurality of the exposed parts on the other end side are supported by an end part support to form emitting parts which emit light from the light source. On the end part support, the end parts of the exposed parts on the other end side are individually supported such that their respective end surfaces are aligned on the same plane.

  • Patent number: 4181204
    Abstract: An oil pressure control means for operating an automatic transmission for automobiles in a manner to establish various speed shift stages in accordance with the balance of the throttle pressure and the governor pressure, including a combination of a brake-sensitive control means operating in response to operation of a brake pedal and an oil passage change-over means, said combination being adapted to supply the line pressure, in lieu of the throttle pressure, to a speed shift valve which establishes the highest speed stage when the brake pedal is stepped on so as positively to shift the speed shift valve to its downshift position by overriding the balance of the governor pressure and the line pressure.
