[0003] In such a structure, restrictions are imposed on the deployment of airbags and the placement of other structures, making it difficult to create a sense of depth and other aesthetic definition in the instrument panel 100. This limits the degree of freedom in the design of the instrument panel.

[0004] Patent Document 1 discloses a configuration in which a lighting device is integrated and positioned in the vehicle width direction on the surface of an instrument panel, partially illuminating the instrument panel to create a sculptural change. Specifically, a step portion that divides the instrument panel into upper and lower sections is provided extending in the vehicle width direction. The rear end of the upper step surface located above the step portion is configured to protrude further toward the rear of the vehicle than the front end of the lower step surface located below. A lighting device is positioned near the front end of the lower step surface, so that the illumination light from the lighting device directly illuminates equipment located near the step portion.

[0005] Furthermore, since the illumination light from the lighting device is irradiated from a recessed portion of the step, the light reflected from the lower surface of the step and / or the folded surface of the upper surface of the step serves as indirect illumination.

DETAILED DESCRIPTION OF THE INVENTION

[0017] (Embodiment) Hereinafter, one embodiment of the present invention will be described with reference to FIGS. As shown in Fig. 1, an instrument panel 12 is disposed in the front of a vehicle interior 10, extending across substantially the entire width of the vehicle in the vehicle width direction (left-right direction in Fig. 1). On this instrument panel 12, a combination meter 13 is mounted as an electrical device on the driver's seat side, and a navigation system 14 and a shift device 15 are mounted in the center.

[0018] Furthermore, on the passenger seat side of the instrument panel 12, as shown in FIG. 3, an airbag device 16 is attached to the rear side of the panel upper surface 12a, and a glove box 20 is attached to the lower part facing the passenger seat.

[0019] As shown in Figures 1, 2 and 3, on the passenger side of the instrument panel 12, a groove portion 30 that extends in the vehicle width direction and opens upward is formed in the rear wall 12b between the panel upper surface 12a and the glove box 20.

[0020] The groove 30 has a groove front wall 32, a groove bottom wall 34, and a groove rear wall 36. The groove front wall 32 corresponds to a downward-facing surface. The groove front wall 32 is formed in a flat shape facing rearward, and as shown in FIG. 3, is inclined so that the upper portion is positioned further rearward than the lower portion, and is disposed to face the passenger seat.

[0021] The groove bottom wall 34 has a front end connected to the lower end of the groove front wall 32 and a rear end connected to the lower end of the groove rear wall 36. The groove bottom wall 34 is formed in a substantially flat plate shape as shown in FIG.

[0022] The groove rear wall 36 has an illumination member storage section 36a and a canopy section 36b at its lower part. The illumination member storage section 36a is formed in the shape of a channel that is open on the groove front wall 32 side, as shown in FIG.

[0023] 3, the eaves portion 36b is connected to the upper part of the lighting member storage portion 36a. That is, the eaves portion 36b is provided at a portion that opens upward to the groove portion 30. The tip of the eaves portion 36b is formed to protrude forward of the lighting member storage portion 36a and to face the groove front wall 32. The height position of the eaves portion 36b is positioned so as to be the same as the height position of the center part of the groove front wall 32 in the up-down direction.

[0024] The visor portion 36b covers the lighting device 40, thereby preventing direct light from the lighting device 40 from reaching the eyes of the driver and the passenger in the front passenger seat. The protruding tip of the canopy portion 36b has a convex curved surface 38. The convex curved surface 38 is formed so that when direct light from the lighting member 42 is reflected by the groove front wall 32 and irradiated onto the curved surface 38, the light is re-reflected, dispersing and irradiating the area on the groove front wall 32 that is irradiated with the direct light and the area that is not irradiated with the direct light. The curved surface 38 corresponds to the opposing surface.

[0025] The illumination member storage section 36a stores an illumination member 42 of the illumination device 40. In this embodiment, the illumination member 42 is made of a light-guiding material. Examples of light-guiding materials include acrylic resin, polycarbonate resin, glass, polystyrene, and urethane. The illumination member 42 is formed in a fiber, rod, or column shape so as to extend in the vehicle width direction.

[0026] As shown in FIG. 4, the lighting device 40 includes an illumination member 42 and a light source 44 connected to one end of the illumination member 42. The light source 44 is, for example, an LED (light-emitting diode), but is not limited to an LED and may be another optical element such as an incandescent lamp. The illumination color of the light source 44 is not limited to white, blue, yellow, red, etc. Furthermore, the illumination color is not limited to a single color, and multiple colors may be used. Alternatively, a color filter may be used. Furthermore, the color of the groove front wall 32 is preferably a color that highlights the illumination color, but is not limited to this color.

[0027] Light from the light source 44 enters the interior of the illumination member 42 from an end face thereof and is emitted from the side face of the illumination member 42 into the groove portion 30 as illumination light. Since the upper front portion of the illumination member storage portion 36a is covered by the eaves portion 36b, the illumination member 42 cannot be directly irradiated up to the top of the groove front wall 32. In this way, the range of direct illumination by the illumination light of the illumination member 42 is limited.

[0028] 3, in this embodiment, the area surrounded by a dotted line extending from the illumination member 42 indicates the range of direct illumination of the illumination light from the illumination member 42. Meanwhile, as shown in FIG. 3, the lower limit of the direct illumination range of the illumination member 42 is located slightly above the lowest limit of the lower part of the groove front wall 32 due to the direction of illumination from the illumination member 42.

[0029] The direct illumination range of the illumination member 42 is an example and is not limited to this range, but it is preferable that the upper limit of the direct illumination range is at least up to the top of the groove front wall 32. (Operation of the embodiment) With the above configuration, when illumination light from the lighting device 40 is irradiated onto the groove front wall 32, the irradiated areas of the groove front wall 32 closer to the lighting device become brighter, and areas farther from the lighting device 40 become darker.

[0030] 3 is reflected at the tip of the eaves portion 36b, and a portion of the light becomes indirect light that is re-reflected at the groove front wall 32. Furthermore, a portion of the light reflected at the tip becomes indirect light that is re-reflected at an area of ​​the groove front wall 32 that is not irradiated with direct light.

[0031] As a result, there are areas on the groove front wall 32 that are irradiated only with direct light, areas that are irradiated with both direct light and light reflected from the tip, and areas that are irradiated only with light reflected from the tip. As a result, the amount of irradiation differs in each area, and the indirect light on the groove front wall 32 can acquire a gradation with various brightness differences as shown in Figure 2.

[0032] Furthermore, since the lighting device 40 is covered by the canopy portion 36b, direct light from the lighting device 40 does not enter the eyes of the driver or a passenger in the front passenger seat. This embodiment has the following features.

[0033] (1) In this embodiment, the instrument panel 12 has a groove front wall 32 (downward facing surface) facing rearward, and a groove 30 that is connected to the groove front wall 32, recessed downward, extends in the vehicle width direction, and opens upward. The lighting device 40 is disposed within the groove 30, extending in the vehicle width direction, and is oriented so that illumination light is irradiated onto the groove front wall 32 (downward facing surface).

[0034] As a result, when illumination light from the lighting device 40 is irradiated onto the groove front wall 32, the illuminated portion of the groove front wall 32 becomes brighter as it is closer to the lighting device, and becomes darker as it is farther from the lighting device 40. As a result, a difference in brightness appears on the falling surface, making it possible to achieve a sense of definition in terms of depth and other aspects of the design.

[0035] In addition, it is possible to create a shape with a sense of depth regardless of the depth of the groove.Furthermore, since indirect lighting creates a sense of air, it is possible to create a design that accentuates the beauty of the lighting.

[0036] (2) In this embodiment, the illumination light from the lighting device 40 is reflected by the groove front wall 32 and is irradiated as indirect light into the vehicle interior. As a result, the indirect light irradiated into the vehicle interior creates a soft atmosphere inside the vehicle interior.

[0037] (3) In this embodiment, the groove front wall 32 and the groove opening portion 30 are Opposite The separated edge portion is provided with a canopy portion 36b that covers the lighting device 40 and extends in the vehicle width direction.

[0038] As a result, since the lighting device 40 is covered by the canopy portion 36b, direct light from the lighting device 40 does not enter the eyes of the driver or the passenger in the front passenger seat. (4) In this embodiment, the canopy portion 36b has a curved surface 38 (opposing surface) that faces the groove front wall 32, and the illumination light reflected by the groove front wall 32 is reflected by the curved surface 38 and is again irradiated onto the groove front wall 32. As a result, a gradation of light and dark is generated on the groove front wall 32 due to the difference between the direct light from the lighting device 40 and the light reflected from the curved surface 38.

[0039] That is, the illumination light irradiated onto the curved surface 38 is reflected by the curved surface 38. A portion of the reflected light is again irradiated onto the groove front wall 32. As a result, there are areas on the groove front wall 32 that are irradiated with both direct light from the lighting device 40 and light reflected from the curved surface 38. Here, the difference in illuminance between the area on the groove front wall 32 irradiated only with direct light and the area irradiated only with the reflected light allows for a gradation of brightness.

[0040] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. The illumination member 42 is not limited to the above embodiment. For example, the light sources themselves arranged in a line or a dotted array may be stored in the illumination member storage section 36a as illumination members to provide illumination. In this case, the illumination members themselves correspond to the illumination device.

[0041] In the above embodiment, the lighting member storage section 36a is formed linearly in the vehicle width direction, and the lighting members 42 are arranged linearly accordingly. However, instead of this, the lighting member storage section 36a may be formed curved in the vehicle width direction so as to have a radius, and the lighting members may be arranged along the inside of this curved lighting member storage section 36a.

[0042] In the above embodiment, the groove front wall 32 is formed flat, but it may be formed convexly toward the groove rear wall 36 (rearward), or conversely, concavely toward the front. By forming it in this manner, light reflected from the groove front wall 32 toward the groove rear wall 36 is re-reflected by the tip of the eaves portion 36b and then reflected by the groove front wall 32 to become indirect light. As a result, the groove front wall 32 has an area illuminated only by direct light, an area illuminated by direct light and reflected light, and an area illuminated only by reflected light. As a result, the amount of illumination differs in each area, and the indirect light on the groove front wall 32 can achieve a gradation of various brightness differences.

[0043] In the above embodiment, the tip of the canopy portion 36b has the curved surface 38 as the opposing surface. However, instead of this, the opposing surface may have a flat surface. [Explanation of symbols]
