Abstract: A light emitting device to be mounted on a mount surface of a vehicular compartment includes a housing including a first section having an air intake hole and a second section having an air discharge hole, a cooling fan device arranged in the first section, and a light emitter arranged in the second section. The housing further includes a discharge cavity having the discharge hole. The light emitter and the cooling fan device are arranged in a first arrangement direction laterally along the mount surface. The light emitter includes a board member and a light emitting element. The board member has a first surface that is opposite the mount surface and a second surface that is an opposite surface of the first surface and on which the light emitting element is mounted. The first surface of the board member is defined as a portion of the discharge cavity.

Abstract: A woven fabric including: a first region where a first fiber as an optical fiber is woven with a second fiber as a non-optical fiber; a second region adjacent to the first region, in which the first fiber is not woven; and a third region adjacent to the second region, in which the first fiber is connected to a light source.

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.

Abstract: A woven fabric which enables protection of optical fiber yarns while the woven fabric is processed into a design woven fabric and easy exposure of the optical fiber yarns when the protection thereof becomes unnecessary, a method for manufacturing a design woven fabric from this woven fabric, and a method for manufacturing an interior material including: A woven fabric having a first constituent yarn having an optical fiber yarn and a non-light guiding yarn and a second constituent yarn having a non-light guiding yarn. The woven fabric having a first region in which the first and second constituent yarns are woven in one layer and a second region which is positioned adjacent to the first region and in which the first and second constituent yarns and are woven in two or more separable layers. The woven fabric has an optical fiber layer and a back protecting layer as the separable layers. The optical fiber layer is a layer formed of the optical fiber yarns.

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.

Abstract: A window device for a vehicle, the window device including: a light-transmitting plate having light-transmitting property and fixed to a vehicle body to physically partition an exterior and an interior of the vehicle; a light-shielding body having light-shielding property and provided along the light-transmitting plate within a view of a vehicle occupant; and a moving mechanism configured to move the light-shielding body up and down so as to widen or narrow a view obtained through the light-transmitting plate above the light-shielding body.

Abstract: A woven fabric includes a first constituent yarn having an optical fiber yarn and a non-light guiding yarn and a second constituent yarn having a non-light guiding yarn. The woven fabric has a first region in which the first and second constituent yarns are woven in one layer and a second region which is positioned adjacent to the first region and in which the first and second constituent yarns and are woven in two or more separable layers. The woven fabric has an optical fiber layer and a back protecting layer as the separable layers. The optical fiber layer is a layer formed of the optical fiber yarns. The back protecting layer is a layer in which the non-light guiding yarn of the first constituent yarn and the non-light guiding yarn of the second constituent yarn are woven. Further, the woven fabric can further comprise a front protecting layer.

Abstract: A vehicular mat to be placed on a vehicular floor panel includes a floor portion, a tunnel portion, a rear edge portion, at least two score lines extending in a vehicular width direction, and a tunnel cutoff portion. The floor portion commonly covers at least two types of vehicular floor panels having different lengths. The rear edge portion is continuous from a vehicular rear edge of the floor portion and has a through hole to be fitted to the opening of the tunnel portion. The vehicular mat is folded along one of the at least two score lines so that the rear edge portion is angled and lifted upward with respect to the floor portion. The tunnel cutoff portion included in the tunnel portion is to be cut off from the vehicular mat to be placed on the second vehicular floor panel.
