Figure 8(c) is a vertical cross-sectional view of the interior panel cut along the cutting line BB shown in Figure 8(a). [Modes for carrying out the invention]

[0011] Figure 1 is a schematic diagram showing an example of the configuration and operation of a vehicle interior component 1 according to an embodiment of the present invention. The vehicle interior component 1 is a vehicle interior component installed in the interior of a vehicle equipped with a first seat and a second seat, and comprises an interior panel 10 having an uneven pattern on its surface and a linear light source 20 that irradiates light toward the surface of the interior panel 10.

[0012] On the uneven pattern on the surface of the interior panel 10, there are periodically arranged a first surface 11 that reflects the light irradiated from the linear light source 20 toward the eye range E1 of the first seat, and a second surface 12 that reflects the light irradiated from the linear light source 20 toward the eye range E2 of the second seat. In FIG. 1, the light reflected by the first surface 11 and traveling toward the eye range E1 of the first seat is schematically shown as L1, and the light reflected by the second surface 12 and traveling toward the eye range E2 of the second seat is schematically shown as L2.

[0013] The eye range is a statistically represented distribution of the positions of the driver's eyes as defined in JIS D 0021:1998, and is represented as an ellipse in a side view and a plan view. The eye range represented as an ellipse in a side view and a plan view is called an eye ellipse.

[0014] In the present embodiment, the eye ranges of the passengers seated in the seats other than the driver's seat are assumed to be the same as the eye range of the driver seated in the driver's seat in terms of the position based on the seat. For example, the eye range E1 of the first seat and the eye range E2 of the second seat in the present embodiment respectively mean the eye ranges of the passengers seated in the first seat and the second seat, and it is assumed that the relative positions of the eye range E1 of the first seat from the first seat and the eye range E2 of the second seat from the second seat are the same. In FIG. 1, the positions of the eye range E1 of the first seat and the eye range E2 of the second seat are schematically shown by eye marks.

[0015] FIG. 2(a) is a perspective view showing an example of the shape of the surface having the uneven pattern of the interior panel 10. FIG. 2(b) is a vertical cross-sectional view of the interior panel 10 cut along the cutting line A-A shown in FIG. 2(a). FIG. 2(c) is a vertical cross-sectional view of the interior panel 10 cut along the cutting line B-B shown in FIG. 2(a).

[0016] When using the interior panel 10 shown in Fig. 2(a), a linear light source 20 is arranged above the interior panel 10 in Fig. 2(a). For example, as shown in Fig. 4 described later, when the linear light source 20 is arranged on the front side of the vehicle relative to the interior panel 10, the upper side of Fig. 2(a) is the front side of the vehicle and the lower side is the rear side of the vehicle.

[0017] The angle between the first surface 11 and the second surface 12 is set according to the installation positions of the interior panel 10 and the linear light source 20, etc., so that the reflected light L1 and the reflected light L2 respectively go toward the eye range E1 of the first seat and the eye range E2 of the second seat.

[0018] The angle between the first surface 11 and the second surface 12 included in the concavo-convex pattern of the interior panel 10 does not have to be constant. The direction toward the eye range E1 of the first seat varies slightly depending on the position of the first surface 11. Similarly, the direction toward the eye range E2 of the second seat varies slightly depending on the position of the second surface 12. Therefore, the angle between the first surface 11 and the second surface 12 included in the concavo-convex pattern of the interior panel 10 may vary depending on the position.

[0019] Also, the area and shape of the first surface 11 and the second surface 12 included in the concavo-convex pattern of the interior panel 10 do not have to be constant. As an example, the concavo-convex pattern shown in Fig. 8(a) can be cited. The concavo-convex pattern shown in Fig. 8(a) includes two types of first surfaces 11 with different areas and shapes.

[0020] According to the vehicle interior part 1, the reflected light L1 by the first surface 11 and the reflected light L2 by the second surface 12 can be selectively sent to the eye range E1 of the first seat and the eye range E2 of the second seat respectively. Therefore, the visibility of the lighting for the passengers sitting on the first seat and the second seat is high, and it can be suitably used as lighting for notifying the passengers (for example, warning displays such as seat belts and half doors).

[0021] Furthermore, according to the vehicle interior component 1, the reflective light emission patterns visible to the occupant seated in the first seat and the occupant seated in the second seat are different. Therefore, for example, when illuminating at night with reduced brightness, it can be used as decorative lighting with excellent decorative expression capabilities that provides different visual appeal for the first seat and the second seat.

[0022] The first and second seats are typically the driver's seat and the passenger seat, in which case the interior panel 10 and the linear light source 20 are installed on the instrument panel or door trim. Alternatively, the first and second seats may be other seat combinations, such as the right rear seat and the left rear seat. When the first and second seats are the right rear seat and the left rear seat, the interior panel 10 and the linear light source 20 are installed on the rear end of the center console or similar location.

[0023] The areas of the first surface 11 and the second surface 12 may be different. If the area of ​​the first surface 11 is larger than the area of ​​the second surface 12, the reflected light L1 directed toward the eye range E1 of the first seat will be stronger than the reflected light L2 directed toward the eye range E2 of the second seat. For example, if the first and second seats are the driver's seat and the passenger seat, by making the area of ​​the first surface 11 larger than the area of ​​the second surface 12, when the brightness is increased for warnings and other notifications, a strong light that is easily visible to the driver's side is sent. On the other hand, a weaker, suppressed light is sent to the passenger seat, where no notification is needed, so as not to bother the occupant seated in the passenger seat.

[0024] The first surface 11 and the second surface 12 may be curved surfaces. When the first surface 11 and the second surface 12 are curved surfaces, the spread of reflected light is greater compared to when they are flat surfaces, making it easier to see the reflected light even when the eye position of an occupant seated in the first or second seat moves.

[0025] The first surface 11 and the second surface 12 may be made of a metal film such as chromium or nickel plating, a metallic coating, or a metallic film in order to increase reflectivity. In this case, typically, the surface of the substrate of the interior panel 10, including the first surface 11 and the second surface 12, is covered with a metal film, coating, or film. Alternatively, the first surface 11 and the second surface 12 may be made of a resin material that has been colored to resemble metal.

[0026] The first surface 11 and the second surface 12 are not limited to mirror surfaces (smooth surfaces), and may be subjected to textured, matte, or dimpled finishes to form shallow, small irregularities on the surface. If light from a linear light source 20 is reflected linearly on the first surface 11 or the second surface 12, these finishes can be applied to the first surface 11 or the second surface 12 to slightly disperse the reflected light and reduce the reflection. Furthermore, the fourth surface located between adjacent first surfaces 11, which is included in the uneven pattern of the interior panel 10, may also be subjected to textured, matte, or dimpled finishes. That is, at least one of the first surface 11, the second surface 12, or the fourth surface may be subjected to textured, matte, or dimpled finishes.

[0027] The linear light source 20 includes a light-emitting device 21 and a rod-shaped light guide 22 that guides the light emitted from the light-emitting device 21 and irradiates it toward the interior panel 10, and functions as a linear light source along the length direction of the light guide 22.

[0028] The light-emitting device 21 includes light-emitting elements such as LEDs. The light-emitting elements included in the light-emitting device 21 are, for example, LEDs called full-color LEDs, which are red, green, and blue LEDs packaged together. In this case, the desired color of light can be emitted by PWM control from an in-vehicle ECU (Electronic Control Unit) via an in-vehicle network.

[0029] The light guide 22 is made of a transparent material such as acrylic that can transmit light emitted from the light-emitting device 21. The light guide 22 also has a prism for reflecting the light propagating inside and emitting it to the outside.

[0030] The prism is composed of, for example, a group of linear grooves arranged on a plane provided along the length of the light guide 22, each extending in a direction perpendicular to the length of the light guide 22. The linear grooves constituting the prism are, for example, straight grooves with a V-shaped cross-section. Alternatively, the prism may be composed of a group of linear projections instead of a group of linear grooves. In this case, the linear projections are, for example, straight projections with a triangular cross-section.

[0031] Alternatively, the light guide 22 may be a light guide containing a diffusing material instead of a prism (for example, a 3M Light String). In that case, the light propagating inside the light guide 22 is reflected by the diffusing material and emitted to the outside.

[0032] The shape of the light guide 22 may be, for example, cylindrical (including one in which a plane containing a prism is provided along the length direction) or polygonal prism. The light guide 22 may also be curved depending on the shape of the space in which the linear light source 20 is installed.

[0033] In the linear light source 20, the light-emitting device 21 is positioned opposite one end face 221 of the light guide 22. Light emitted from the light-emitting device 21 enters the interior of the light guide 22 from one end face 221 and propagates along the length of the light guide 22. The light propagating inside the light guide 22 is reflected by a prism or diffuser and then emitted from the light guide 22 towards the interior panel 10.

[0034] Most of the light propagating inside the light guide 22 travels from the end face 221 facing the light-emitting device 21 toward the opposite end face 222. Therefore, as shown in Figure 1, the component of the direction of propagation of the light emitted from the light guide 22 that is parallel to the length of the light guide 22 is oriented from end face 221 toward end face 222 (from left to right in Figure 1). Consequently, the component of the light reflected by a nearly horizontal reflective surface, such as the first surface 11 illustrated in Figure 1, that is parallel to the length of the light guide 22 is oriented from end face 221 toward end face 222 (from left to right in Figure 1).

[0035] In the linear light source 20, the orientation of the light-emitting device 21 to face either end face of the light guide 22, that is, the orientation from which light enters the light guide 22, is determined according to circumstances such as whether a strong beam of light should be directed towards the eye range E1 of the first seat or the eye range E2 of the second seat.

[0036] For example, in Figure 1, if the area of ​​the first surface 11 is larger than the area of ​​the second surface 12, and you want to send strong light towards the eye range E1 of the first seat, then the light-emitting device 21 is installed so as to face the end face of the light guide 22 opposite to the eye range E1 of the first seat (the left end face 221 in Figure 1).

[0037] More specifically, for example, if the first and second seats are the driver's seat and the passenger seat, by installing the light-emitting device 21 so as to face the passenger-side end face (the left end face 221 in Figure 1) of the light guide 22, strong light reflected from the first surface 11, which has a large surface area and is nearly horizontal, can be sent to the eye range E1 of the first seat.

[0038] Figure 3 shows an example of the installation of the interior panel 10 in the vehicle interior. Figure 4 is a schematic cross-sectional view along the front-rear direction of the vehicle, showing an example of the installation of the interior panel 10 and the linear light source 20. In the examples shown in Figures 3 and 4, the vehicle interior component 1 is installed on the vehicle's instrument panel 50.

[0039] Specifically, the linear light source 20 is installed in the space behind the upper panel 51 near the center of the instrument panel 50 (between the driver's seat and the passenger's seat) with the length of the light guide 22 aligned with the width of the vehicle, and the interior panel 10 is installed on the upper flat surface 53 of the lower panel 52 near the center of the instrument panel 50.

[0040] In this case, the light emitted from the linear light source 20 passes through the gap 54 provided between the upper panel 51 and the lower panel 52 and is reflected by the interior panel 10. The light reflected by the first surface 11 travels towards the eye range E1 of the driver's seat, which is the first seat, and the light reflected by the second surface 12 travels towards the eye range E2 of the passenger seat, which is the second seat.

[0041] The linear light source 20 may include a housing 23 that accommodates a light guide 22, as shown in Figure 4. The housing 23 has a structure that, for example, fixes a light-emitting device 21 to the end of the light guide 22.

[0042] Furthermore, in the vehicle interior component 1, if the area of ​​the first surface 11 is larger than the area of ​​the second surface 12, it is preferable that the relatively larger first surface 11 and the fourth surface 14 located between adjacent first surfaces 11 suppress the reflection (reflective glare) of high-luminosity external light, such as direct sunlight, toward the occupants seated in the first or second seat.

[0043] To achieve this, it is preferable to adjust the installation position of the vehicle interior component 1 and the angles of the first surface 11 and the fourth surface 14 so that the light L0 that enters the passenger compartment through the window of the vehicle on which the vehicle interior component 1 is installed, and is directly incident on the first surface 11 and the fourth surface 14 and reflected, does not reach the eye range E1 of the first seat or the eye range E2 of the second seat.

[0044] For example, in the examples shown in Figures 3 and 4, light entering the cabin from the front windshield 55 is blocked by the instrument panel 50 and other components, so it does not directly strike the first surface 11, the second surface 12, and the fourth surface 14. Also, light entering the cabin from the side windows 56 and the rear window strikes the first surface 11 and the fourth surface 14 from a direction significantly different from the light from the linear light source 20 installed inside the instrument panel 50, so it is not reflected by the first surface 11 and the fourth surface 14 towards the driver's eye range E1 or the passenger's eye range E2.

[0045] Furthermore, if the light L0 that is directly incident on the first surface 11 and the fourth surface 14 and reflected does not go toward the eye range E1 of the first seat or the eye range E2 of the second seat, then the light L1 that is irradiated from the linear light source 20, reflected by the first surface 11 and directed toward the eye range E1 of the first seat, and the light L2 that is irradiated from the linear light source 20, reflected by the second surface 12 and directed toward the eye range E2 of the second seat can be made more prominent. This can further improve the visibility of notifications and other information provided by light L1 and light L2.

[0046] In order to further reduce the external light reflected towards occupants seated in the first and second seats by the uneven pattern of the interior panel 10, it is preferable that the light L0 that enters the vehicle interior from the vehicle window and is directly incident on all surfaces constituting the uneven pattern of the interior panel 10, including the first surface 11 and the fourth surface 14, and is reflected, does not go towards the eye range E1 of the first seat or the eye range E2 of the second seat.

[0047] Figure 5 is a schematic diagram showing an example of the configuration and operation of vehicle interior part 2, which is a modified version of vehicle interior part 1. In vehicle interior part 2, a linear light source 30 is used, which includes a plurality of light-emitting devices 31 arranged in a linear fashion.

[0048] The linear light source 30 includes, for example, a plurality of light-emitting devices 31, a substrate 32 on which the plurality of light-emitting devices 31 are mounted, and a light-transmitting cover 33, as shown in Figure 5. The light-emitting devices 31 include light-emitting elements such as LEDs, similar to the light-emitting devices 21. The linear light source 30 functions as a linear light source along the direction in which the light-emitting devices 31 are aligned.

[0049] In the vehicle interior component 2, similar to the vehicle interior component 1, the light emitted from the linear light source 30 is reflected by the first surface 11 of the interior panel 10 toward the eye range E1 of the first seat, and by the second surface 12 toward the eye range E2 of the second seat.

[0050] Figure 6(a) is a perspective view showing an example of the surface shape of an interior panel 10 included in the vehicle interior parts 2, which has an uneven pattern. Figure 6(b) is a vertical cross-sectional view of the interior panel 10 cut along the cutting line AA shown in Figure 6(a). Figure 6(c) is a vertical cross-sectional view of the interior panel 10 cut along the cutting line BB shown in Figure 6(a).

[0051] When using the interior panel 10 shown in Figure 6(a), the linear light source 30 is positioned above the interior panel 10 in Figure 6(a). For example, if the linear light source 30 is positioned further forward than the interior panel 10, as shown in Figure 4, then the upper part of Figure 6(a) will be the front of the vehicle and the lower part will be the rear of the vehicle.

[0052] Figures 7(a) and 7(b) are schematic diagrams showing examples of the configuration and operation of vehicle interior part 3, which is a modified example of vehicle interior part 1. Vehicle interior part 3 comprises an interior panel 10 having an uneven pattern on its surface, and a linear light source 40 that irradiates light toward the interior panel 10.

[0053] The linear light source 40 includes a rod-shaped light guide 22, a light-emitting device 21a that supplies light into the interior of the light guide 22 from one end face 221 of the light guide 22, and a light-emitting device 21b that supplies light into the interior of the light guide 22 from the other end face 222 of the light guide 22, and functions as a linear light source along the length direction of the light guide 22.

[0054] Light-emitting devices 21a and 21b are light-emitting devices similar to the light-emitting device 21 of the linear light source 20. Figure 7(a) shows the state when light-emitting device 21a is lit and light-emitting device 21b is off, and Figure 7(b) shows the state when light-emitting device 21a is off and light-emitting device 21b is lit.

[0055] The surface of the interior panel 10 has a textured pattern in which a first surface 11, a second surface 12, and a third surface 13 are arranged periodically. The first surface 11 is a surface that reflects light emitted from the light-emitting device 21a and irradiated from the light guide 22 toward the eye range E1 of the first seat, and reflects light emitted from the light-emitting device 21b and irradiated from the light guide 22 toward the eye range E2 of the second seat.

[0056] The second surface 12 is a surface that reflects the light emitted from the light-emitting device 21a and irradiated from the light guide 22 toward the eye range E2 of the second seat. The third surface 13 is a surface that reflects the light emitted from the light-emitting device 21b and irradiated from the light guide 22 toward the eye range E1 of the first seat.

[0057] In Figure 7(a), when the light-emitting device 21a is lit, the light reflected by the first surface 11 and directed toward the eye range E1 of the first seat is shown as L1, and the light reflected by the second surface 12 and directed toward the eye range E2 of the second seat is shown as L2. Similarly, in Figure 7(b), when the light-emitting device 21b is lit, the light reflected by the first surface 11 and directed toward the eye range E2 of the second seat is shown as L3, and the light reflected by the third surface 13 and directed toward the eye range E1 of the first seat is shown as L4.

[0058] Figure 8(a) is a perspective view showing an example of the surface shape of an interior panel 10 included in the vehicle interior part 3, which has an uneven pattern. Figure 8(b) is a vertical cross-sectional view of the interior panel 10 cut along the cutting line AA shown in Figure 8(a). Figure 8(c) is a vertical cross-sectional view of the interior panel 10 cut along the cutting line BB shown in Figure 8(a).

[0059] When using the interior panel 10 shown in Figure 8(a), the linear light source 40 is positioned above the interior panel 10 in Figure 8(a). For example, if the linear light source 40 is positioned further forward than the interior panel 10, as shown in Figure 4, then the upper part of Figure 8(a) will be the front of the vehicle and the lower part will be the rear of the vehicle.

[0060] In the vehicle interior component 3, the surface that reflects light toward the eye range E1 of the first seat and the eye range E2 of the second seat is different when the light-emitting device 21a is lit and when the light-emitting device 21b is lit. Therefore, occupants seated in the first and second seats will see different patterns when the light-emitting device 21a is lit and when the light-emitting device 21b is lit.

[0061] Furthermore, in the vehicle interior component 3, the pattern visible from the first seat by reflected light L1 when the light-emitting device 21a is lit is almost the same as the pattern visible from the second seat by reflected light L3 when the light-emitting device 21b is lit. Moreover, if the second surface 12 and the third surface 13 have mirror symmetry as illustrated in Figure 8 (in the example shown in Figure 8, they are mirror symmetry with respect to a plane parallel to the vertical direction of Figure 8 and perpendicular to the plane of the paper), then the pattern visible from the second seat by reflected light L2 when the light-emitting device 21a is lit is almost the same as the pattern visible from the first seat by reflected light L4 when the light-emitting device 21b is lit. In this case, the pattern visible from the first seat and the pattern visible from the second seat are reversed between when the light-emitting device 21a is lit and when the light-emitting device 21b is lit.

[0062] The following describes examples (1) to (3) of how to use the vehicle interior part 3, taking advantage of the features of the vehicle interior part 3 described above.

[0063] (1) Differentiating between the use of notification expressions for the first seat and the second seat. The vehicle's interior lighting 3 can be used to provide different notification expressions for the first and second seats. For example, as shown in Figures 7 and 8, when the first surface 11 has the largest area among the first surface 11, the second surface 12, and the third surface 13, the reflected light L1 when the light-emitting device 21a is lit is the strongest light suitable for a notification expression visible from the first seat, and the reflected light L3 when the light-emitting device 21b is lit is the strongest light suitable for a notification expression visible from the second seat. Therefore, when it is desired to provide a notification by illumination to the first seat, the light-emitting device 21a can be lit to send a strong light to the first seat, and when it is desired to provide a notification by illumination to the second seat, the light-emitting device 21b can be lit to send a strong light to the second seat. Examples of the above notification expressions include seat belt and half-door warnings, and illumination expressions for safe disembarking assistance.

[0064] (2) Differentiating the illumination and lighting colors for the first and second seats. The illumination time, brightness pattern, and lighting color of the vehicle's interior components 3 can be changed for the first and second seats. For example, by simultaneously illuminating light-emitting devices 21a and 21b, which have different brightness change patterns and emission colors, the same pattern can be displayed to the first and second seats with different illumination expressions and colors. More specifically, for example, by dividing the lighting colors between the first and second seats into red and blue, different feelings of warmth and coolness can be expressed, or by dividing them into amber and red, a relaxed atmosphere and a sense of dynamism can be expressed, respectively.

[0065] (3) Two-color display and dynamic representation of patterns For the first and second seats, the vehicle's interior components 3 can display two-color patterns and provide dynamic effects. For example, by simultaneously lighting up light-emitting devices 21a and 21b, which emit different colors, the first seat can see a two-color pattern displayed by reflected light L1 and reflected light L4 of different colors, while the second seat can see a two-color pattern displayed by reflected light L2 and reflected light L2 of different colors. Furthermore, by simultaneously lighting up light-emitting devices 21a and 21b with different brightness change patterns, dynamic expression of the pattern becomes possible. In this way, by differentiating the light-emitting colors and brightness change patterns of light-emitting devices 21a and 21b, complex expressions such as transitions and sparkles become possible.

[0066] (Effects of the embodiment) According to the above-described embodiment of the present invention, the vehicle interior components 1, 2, and 3 can selectively direct reflected light toward the eye range of the seat, thus providing lighting suitable for notifying occupants of illumination. Furthermore, since the interior panel 10 that reflects light from the linear light sources 20, 30, and 40 has a three-dimensional design with an uneven pattern, decorative lighting can be provided that highlights the beautiful form and texture created by shadows. Therefore, according to the embodiment of the present invention, it is possible to provide vehicle interior components that are highly decorative and can provide indirect lighting suitable for notifying occupants of illumination.
