In FIG. 3, the upper side is the vehicle interior side, and the lower side is the vehicle interior side.

  The plate-shaped member 30 has a long longitudinal shape in the vehicle front-rear direction. The plate-like member 30 is made of, for example, a synthetic resin material (for example, acrylic resin or polycarbonate) having a refractive index sufficiently higher than that of air and substantially transparent (having light transmittance). In addition, although the thickness of the plate-shaped member 30 is set to about 2-3 mm, for example, it is not limited to this.

  The first design layer 40 has light transparency, and a pattern 41 (for example, a gradation pattern of shades of color, a shaded portion in FIG. 1) is formed. The second design layer 50 is light-transmitting, and a pattern 51 (for example, a woodgrain pattern, the shaded portion in FIG. 1) is formed over substantially the entire surface. Note that the patterns 41 and 51 are light transmissive. In addition, the 1st design layer 40 and the 2nd design layer 50 can each be formed using the decorative film in which the pattern was printed. For example, the 1st design layer 40 and the 2nd design layer 50 can be formed by insert molding which affixes a decorating film simultaneously with injection-molding the plate-shaped member 30. FIG.

  Moreover, it is good also as the 1st design layer 40 (or 2nd design layer 50) by transferring only the pattern printed on the decorating film to the plate-shaped member 30. Moreover, it is not limited to the thing using a decorating film, For example, the 1st design layer 40 (pattern 41) and the 2nd design layer 50 (by applying the coating material which has a light transmittance with respect to the plate-shaped member 30 ( A pattern 51) may be formed.

  The light shielding layer 60 is made of, for example, a light shielding film or paint, and exhibits, for example, black. As shown in FIGS. 1 and 2, an opening 61 is formed in a portion of the light shielding layer 60 that overlaps the pattern 41. In addition, in FIG. 1, although the opening part 61 illustrated what makes a substantially V shape, it is not limited to this.

  As shown in FIG. 3, the LED 21 (side surface side light source) is provided so as to face the side surface 31 of the plate-like member 30. As shown in FIG. 1, the LED 21 is provided, for example, on the back surface of the middle board 11, and the light emission surface 21 </ b> A is arranged so as to face the side surface 31. Thereby, LED21 becomes a structure which can radiate | emit light with respect to the side surface 31. FIG.

  The plate-like member 30 is a light guide plate, and guides the light incident from the side surface 31 (light incident surface) in the interior, and then emits the light from the entire surface on the vehicle interior side (light emitting surface). Is possible. Specifically, light incident from the side surface 31 is guided by repeating total reflection inside the plate member 30. A scattering reflection layer (not shown) for reflecting light while scattering the light is provided on the surface of the plate-like member 30 outside the passenger compartment. As a result, a part of the light reaching the surface outside the passenger compartment (and hence the scattering reflection layer) of the plate-like member 30 is scattered and reflected so that it is totally reflected on the surface of the plate-like member 30 on the vehicle interior side. The light is incident at an angle that is not. As a result, the light inside the plate member 30 can be emitted from the surface of the plate member 30 on the vehicle interior side. The configuration of the plate member 30 is not limited to that described above, and can be changed as appropriate. After the light incident from the side surface 31 is guided inside, the light can be emitted from the surface on the vehicle interior side. Any configuration is possible. For example, particles that scatter light are included in the plate-like member 30, or a fine groove (for example, a V-groove) or a dot pattern that scatters and reflects light is provided on the surface of the plate-like member 30 on the outside of the passenger compartment. Thus, the light may be emitted from the surface on the vehicle interior side.

  Further, in the plate-like member 30, part of the light traveling toward the vehicle interior outside is reflected by the second design layer 50 and becomes light traveling toward the vehicle interior side. Thereby, the light emitted from the surface of the plate-like member 30 on the vehicle interior side becomes light reflecting the pattern 51.

  Moreover, as shown in FIG. 3, LED23 is provided in the vehicle interior outer side (lower side of FIG. 3) of the decorating member 20. As shown in FIG. The LED 23 (light source outside the vehicle compartment) is arranged so as to overlap the opening 61 from the outside of the passenger compartment, and the light emission surface 23A thereof is arranged facing the vehicle interior side. Thereby, the LED 23 is configured to be able to emit light to the opening 61. The LEDs 21 and 23 are connected to a power supply device (not shown) such as a battery mounted on the vehicle, and can be individually turned on and off. The LEDs 21 and 23 emit visible light (for example, white light), but the color of the emitted light is not limited to white and can be changed as appropriate. Moreover, you may make the color of the emitted light of LED21 and LED23 a different color.

  Next, the operation and effect of this embodiment will be described. In the door trim 10 of the present embodiment, when the occupant views the decorative member 20 from the vehicle interior side, the first design layer 40 can be seen on the front side, and the plate-like member 30 is transmitted to the back side of the first design layer 40. Layer 50 is visible. As a result, a complicated pattern in which the pattern 41 (for example, gradation pattern) of the first design layer 40 and the pattern 51 (for example, wood pattern) of the second design layer 50 are overlapped can be expressed, and the design property can be further enhanced. Can do. And by interposing the plate-shaped member 30 between the 1st design layer 40 and the 2nd design layer 50, the three-dimensional effect (unevenness | corrugation) of the pattern of the 2nd design layer 50 can be emphasized more, and design property is improved. Can be higher.

  Further, the LED 21 is disposed opposite to the side surface 31 of the plate-like member 30 and can emit light to the side surface 31. Light emitted from the LED 21 enters the plate member 30 from the side surface 31 of the plate member 30. Inside the plate-like member 30, light is guided by repeating total reflection. In the plate member 30, the light reflected at the boundary between the plate member 30 and the second design layer 50 passes through the first design layer 40 and is emitted into the vehicle interior (see arrow L1 in FIG. 3). . Thereby, the pattern 51 of the 2nd design layer 50 and the pattern 41 of the 1st design layer 40 can be illuminated with the light of LED21.

  Temporarily, when it is set as the structure which illuminates the 2nd design layer 50 with the light from the vehicle interior side, the light which permeate | transmitted the pattern 51 of the 2nd design layer 50 will be visually recognized by the passenger | crew. With such light, it is difficult to express the three-dimensional feeling (shadows, etc.) of the pattern 51, and the design is degraded. Moreover, if it is set as the structure which shines light from the vehicle interior side with respect to the decorating member 20 and shines the pattern 51, it will be necessary to arrange | position a light source to the vehicle interior side of the decorating member 20, and vehicle interior space will become narrow. End up. As in this embodiment, the LED 21 is disposed opposite to the side surface 31 of the plate-like member 30, and the plate-like member 30 is used as a light guide plate. About 50, the pattern 51 can be illuminated by irradiating light from the vehicle interior side.

  Further, the second design layer 50 is covered from the outside of the passenger compartment, and the light shielding layer 60 in which the opening 61 is formed. The light shielding layer 60 is disposed outside the passenger compartment with respect to the opening 61 and emits light to the opening 61. The second design layer 50 is light transmissive.

  In the present embodiment, the light emitted from the LED 23 is transmitted through the opening 61 in the order of the second design layer 50, the plate-like member 30, and the first design layer 40, and is emitted into the vehicle interior (the arrow line in FIG. 3). L2). Thereby, the passenger | crew can visually recognize the shape of the opening part 61 as a pattern in addition to the pattern 41 of the 1st design layer 40, and the pattern 51 of the 2nd design layer 50. FIG. Thereby, a complicated pattern can be expressed and design nature can be made higher. Further, it is possible to produce an effect of switching the presence or absence of the pattern of the opening 61 by turning on and off the LED 23.

In the present embodiment, an uneven portion 151 (texture pattern) is formed on the surface on the vehicle interior side (surface on the plate-like member 30 side) of the second design layer 150 in the decorative member 120. Thereby, the light reflected by the uneven | corrugated | grooved part 151 can be radiate | emitted in a vehicle interior, and a more complicated design can be expressed. Moreover, the emitted light from the LED 21 is reflected by the uneven portion 151 and travels toward the vehicle interior side. Thereby, compared with the structure which radiate | emits the light which permeate | transmitted the uneven | corrugated | grooved part 151 in the vehicle interior, the three-dimensional effect of the uneven | corrugated | grooved part 151 can be emphasized.
