  • 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.

  • Patent number: 11848527
    Abstract: A terminal includes a terminal body and a slider. The terminal body is formed by processing a metal sheet. The terminal body is coupled to a front end of an electric wire with respect to an extending direction in which the electric wire extends. The terminal body holds the electric wire. The slider is slidable in the extending direction relative to the terminal body. The terminal body includes connecting tabs that includes contact surfaces contactable with the electric wire. Each of the connecting tabs has a cantilever shape. The slider includes pressing portions that press the connecting tabs so that the connecting tabs deform and the contact surfaces contact the electric wire when the slider is slid. The connecting tabs include burrs that are produced during processing of the metal sheet. The burrs protrude from the contact surfaces toward the electric wire.
