  • Patent number: 10549684
    Abstract: A skin material for vehicle interior includes a woven fabric woven by using a side emission type optical fiber and a multifilament as warp or weft, and is joined to a substrate for vehicle interior to constitute a vehicle interior material. In a surface of the woven fabric which constitutes the inside of a vehicle compartment, a virtual surface constituted by connecting side surfaces, on the inside of the vehicle compartment, of the side emission type optical fibers is in close vicinity to the substrate for vehicle interior, as compared with a virtual surface constituted by connecting side surfaces, on the inside of the vehicle compartment, of the multifilaments. Examples of the vehicle interior material in which the skin material for vehicle interior is used include door trims and roof trims.

  • 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: 8128166
    Abstract: A pull-in recess is formed in a seat pad (30). The pull-in recess is partly formed as a through hole penetrating to a back surface of the seat pad. A seat cover (40) is formed into a bag shape. A string-shaped member (50) for drawing the seat cover (40) and attaching the same to the seat pad (30) is disposed along an opening of the seat cover. The seat cover (40) is provided with a pull-in portion at a position corresponding to the pull-in recess of the seat pad (30). The pull-in portion is inserted into the through hole of the seat pad (30). A distal end of the pull-in portion is provided with a retainer portion (47a and 47b) that is capable of engaging the string-shaped member (50). The retainer portions (47a and 47b) inserted into the through holes (34a and 34b) of the seat pad (30) are engaged with the string-shaped member (50) while the drawing action force of the string-shaped member (50) is applied thereto, which force can be produced when the seat cover is attached by drawing.
