Abstract: Provided is a vehicle interior component capable of exhibiting an in-vehicle lighting function even without electricity supply from a vehicle body power source. A vehicle interior component attached to a vehicle is a vehicle door lining, which includes a light-emitting member emitting light toward the inside of the vehicle, a power generation member electrically connected to the light-emitting member and supplying electricity to the light-emitting member, and a power storage member electrically connected to the light-emitting member and the power generation member and storing electricity. The light-emitting member, the power generation member, and the power storage member are disposed at different positions on the surface of the vehicle door lining on the vehicle inside. In addition, the power generation member is sheet-shaped or film-shaped and is disposed along the surface of the vehicle door lining.

Abstract: A light-emitting part for a vehicle having a light-emitting region is described. The light-emitting part includes an irradiation body which i) includes a dot-shaped light source and a planar plate-shaped light guide body that emits light from the dot-shaped light source, and ii) emits the light toward a front side of the light-emitting region. The light-emitting part includes a curved plate-shaped transmissive body disposed so that the light emitted from the irradiation body is transmitted through the curved plate-shaped transmissive body. The curved plate-shaped transmissive body includes portions which are separated from the planar plate-shaped light guide body by different gaps. Also included is a surface brightness adjusting portion which adjusts a brightness of an outer surface of the light-emitting region in response to a size of the gap and a distance from the dot-shaped light source.
