  • Patent number: 11919442
    Abstract: A vehicle interior lighting device includes a light source which is installed at an end of an instrument panel of a vehicle. Light emitted from the light source propagates from the instrument panel toward a door panel, and is projected on a surface of a door trim of the door panel. A decorative pattern element is installed on a light emitting side of the light source. As light from the light source passes through the decorative pattern element, the light can create a pattern on a surface of the door trim. Because the light source is installed on the instrument panel spaced from the door trim rather than on the door trim itself, light can be projected on a large area of the door trim. Furthermore, an impressive feature of a decorative pattern which changes in accordance with a door opening angle can be achieved.

  • Publication number: 20160075310
    Abstract: A defrosting performance identical to that in a conventional front defroster nozzle device is exhibited by a simpler structure even in the case of decreasing the overall length of a front defroster nozzle device in the direction of vehicle width. A current of air from a front blow-opening formed on the same side as a windshield is mainly sent to the left and right end portions of the windshield and a current of air from a rear blow-opening adjacent to the front blow-opening and formed further inside the vehicle interior than the front blow-opening is mainly sent to the central portion of the windshield. Accordingly, currents of air are inhibited from interfering with each other.
