Japanese Unexamined Patent Publication No. 2008-143425

By the way, in the above-mentioned lighting device, when it is desired to irradiate a plurality of places in a vehicle, a light source and a light guide body are required for each of the plurality of places, and there is a problem that the cost is high. Further, even when there are circumstances such as wanting to have different brightness at a plurality of locations, a plurality of light sources and light guides must be used.

In order not to increase the number of light sources and light guides, arrange the locations where you want to irradiate the long light guides, and apply V-groove processing or grain processing to the necessary parts of the light guides to partially emit the light from the light sources. It is conceivable to control the appearance of light by scattering it. However, in such a case, there is a problem that processing cost and work man-hours are required.

The technique disclosed in the present specification has been completed based on the above circumstances, and has different visual sensitivities to a viewer at a plurality of locations without increasing the number of light sources and light guides. It is an object of the present invention to provide a lighting structure of an interior material for a vehicle which can be illuminated.

The technique disclosed herein is a lighting structure in an interior material for a vehicle, comprising a light source and a longitudinal light guide body capable of guiding the light emitted from the light source. The body is provided with at least one bent portion that is bent in the longitudinal direction, and guides the light from the light source incident from one end side to the other end side while guiding the light internally. In, the light is provided by emitting light toward the vehicle interior, and the vehicle interior material is a first part that provides bright lighting to a viewer who gets on the vehicle, and the above-mentioned A second portion, which is a portion that provides darker illumination to the viewer than the first portion, is provided, and the light guide body has the first direction from one end side toward the other end side. In the portion, it is installed so as to be in a direction closer to the eyes of the viewer, and in the second portion, it is installed so as to be in a direction away from the eyes of the viewer.

In a light guide body that emits light while guiding light from a light source incident from one end side internally, the direction of the light traveling in the light guide body and the light emitted from the light guide body are emitted. The appearance of the light by the viewer differs depending on the direction of the line of sight of the viewer who sees the light. Specifically, when the light source and the light guide are arranged so that the traveling direction of the light is close to the eyes of the viewer, the emitted light has high luminosity factor (looks bright) to the viewer. On the other hand, if the light source and the light guide are arranged so that the traveling direction of the light is away from the eyes of the viewer, the emitted light has low visibility (looks dark) to the viewer. The event is recognized.

The technique disclosed in the present specification utilizes such an event, and according to the above configuration, one end of the light guide body can be obtained without using a plurality of light sources and light guide bodies having different brightness. By installing the light so that the direction from the side to the other end side (the traveling direction of the light) is closer to the eyes of the viewer in the first portion, the viewer is illuminated brightly and the second portion is visually recognized. By installing it so as to be away from the eyes of the person, it is possible to illuminate the viewer darker than the first portion. That is, it is possible to illuminate a plurality of parts of the vehicle interior material so as to have different visual sensitivities to the viewer.

In the above configuration, the light guide is installed so that the direction from one end side to the other end side is the direction from the front side to the rear side of the vehicle interior material in the first portion, and in the second portion. , It may be installed so as to be in the direction from the rear side to the front side.

FIG. 1 is a front view of the door trim 10 as viewed from the vehicle interior side, and FIG. 2 is a rear view of the door trim 10. The door trim 10 constitutes a vehicle interior side portion of the vehicle door, and is attached to the door inner panel (not shown) from the vehicle interior side. The door trim 10 is mainly composed of the trim board 11, and is composed of a plurality of parts assembled to each other. The trim board 11 of the present embodiment is mainly composed of an upper board 12, a lower board 13, an armrest board 14, and a pocket board 15.

The armrest board 14 is fastened to the upper side of the lower board 13 at the center of the trim board 11 in the vertical direction and closer to the rear of the vehicle, so that the armrest 16 used as an armrest for the occupant projects toward the vehicle interior side. It is formed. The upper surface 16A of the armrest 16 extends along a substantially horizontal direction. An armrest opening (not shown) that opens upward is formed near the front of the upper surface 16A, and a switch operation unit (not shown) for opening and closing the door window is formed in this armrest opening. It is provided.

A door grip 18 extends to the front side of the armrest 16. The door grip 18 is provided so as to be inclined diagonally upward from the front side portion of the upper surface 16A of the armrest 16 which is substantially horizontal. The door grip 18 is separated from the plate surface (the surface on the vehicle interior side) of the lower board 13 so that the occupant can easily grip it, and is integrated with the lower board 13 at the front end thereof with respect to the trim board 11. It is fixed.

Of the upper board 12, a handle accommodating portion 20 is provided above the switch operation portion and near the joint portion with the lower board 13. The handle accommodating portion 20 has a handle opening provided in the upper board 12. The inside handle bezel 21 is attached to the portion 12A from the vehicle interior side. FIG. 4 is a cross-sectional view taken along the line II of FIG. 2, and as shown in the figure, the inside handle bezel 21 includes a back wall 22 and a standing wall 23 that rises from the peripheral edge of the back wall 22 toward the vehicle interior side. It has a flange portion 24 extending radially outward from the edge portion of the vertical wall 23. The inside handle bezel 21 is attached so that the flange portion 24 overlaps the peripheral edge of the handle opening 12A of the upper board 12 from the vehicle interior side, so that the flange portion 24 is recessed from the vehicle interior surface of the upper board 12 toward the vehicle interior outside. The handle accommodating portion 20 in the state of being in a state is configured. Inside the handle accommodating portion 20, an inside handle (not shown) for opening and closing the vehicle door is accommodated.

Further, a door pocket 27 is formed below the armrest 16 and the door grip 18. The door pocket 27 is formed by attaching the pocket board 15 to the lower side of the lower board 13 outside the passenger compartment. The door pocket 27 has a pocket opening 27A that opens toward the upper side of the vehicle, and is configured to be capable of accommodating articles and the like inside. The pocket opening 27A has a long shape in the front-rear direction of the vehicle. The door pocket 27 is located below the armrest 16 and the door grip 18 at a distance from the lower ends of the armrest 16 and the door grip 18.

The above-mentioned upper board 12 and lower board 13 are fastened by superimposing a plurality of mounting pieces 13B protruding upward from the upper edge of the lower board 13 on the outside of the passenger compartment of the upper board 12 and fixing them to the upper board 12. (See Fig. 2). Details will be described later.

The door trim 10 of the present embodiment is provided with a lighting device 30. The lighting device 30 includes an LED (an example of a light source) 31 and a light guide body 33 capable of guiding light emitted from the LED 31 (see FIG. 5). The LED 31 is housed in the LED housing case 32 in a state of being mounted on the LED board. Further, the LED 31 is connected to a power supply device such as a battery mounted on the vehicle via a control device (not shown).

The light guide body 33 has a substantially circular cross section and is made of a flexible long (rod-shaped) light guide material. The light guide material is a material having a refractive index sufficiently higher than that of air and transmitting light, and examples thereof include acrylic resins.

The light guide body 33 is attached to the LED housing case 32 in a state where the end surface on one end (hereinafter referred to as 33A) side in the longitudinal direction is arranged so as to face the light emitting surface of the LED 31. As a result, the end surface on the one end 33A side is regarded as a light incident surface on which the light emitted from the LED 31 is incident. When the light traveling inside the light guide 33 enters the interface with the external air layer at an incident angle larger than the critical angle, the light guide body 33 is configured to propagate inside while being totally reflected. That is, the structure is such that light can be guided to the other end (hereinafter referred to as 33B) side inside the inside (see FIG. 5).

The outer peripheral surface (side surface) of the light guide body 33 is, for example, coated with a fluororesin, and is configured to emit light introduced into the light guide body 33 to the outside. There is. That is, the light incident from one end 33A (light incident surface) side of the light guide body 33 is guided by repeating total reflection inside the light guide body 33, and a part of the light is guided to the entire outer peripheral surface in the middle of the light guide. It is possible to emit from. As a result, the entire light guide body 33 becomes a linear light source, and it is possible to illuminate the surroundings thereof. As described above, the outer peripheral surface of the light guide body 33 is a light emission surface that emits light incident on the inside of the light guide body 33 from one end 33A (light incident surface) side to the outside.

By the way, in such an illuminating device 30, the viewer is determined by the traveling direction of the light guided in the light guide 33 and the direction of the line of sight of the viewer who visually recognizes the light emitted from the light guide 33. The phenomenon that the appearance of light (luminosity factor) changes due to the light is observed. Specifically, to explain with reference to FIG. 5, the light guide body 33 is such that the traveling direction of the light emitted from the LED 31 and guided in the light guide body 33 is the direction toward the eyes of the viewer. When the light is arranged (when the emitted light is visually recognized from the position A in FIG. 5), the light guide is arranged so that the traveling direction of the light is in the direction away from the eyes of the viewer (when the light is arranged. Compared with the case where the emitted light is visually recognized from the position B in FIG. 5), the phenomenon that the emitted light looks brighter is recognized.

By the way, in the door trim 10 of the present embodiment, it is desired that the above-mentioned handle accommodating portion 20, the upper surface 16A of the armrest 16 and the pocket opening 27A are brightly illuminated by the lighting device 30 to the viewer who is in the vehicle. I have a request. Further, among these, the upper surface 16A of the armrest 16 is provided with a switch operation portion, so that it is the portion to be brightest (hereinafter, the portion for which bright illumination is desired is referred to as the first portion 11B), and the handle accommodating portion. The 20 and the pocket opening 27A are portions that may be darker than the upper surface 16A of the armrest 16 (hereinafter, a portion that may be darker than the first portion 11B is referred to as a second portion 11D).

Therefore, the lighting device 30 of the present embodiment is installed on the trim board 11 as follows. As shown in FIG. 2, the LED housing case 32 (that is, LED 31) of the lighting device 30 is installed on the outside of the passenger compartment near the upper corner on the rear side of the back wall 22 of the inside handle bezel 21 of the steering wheel housing 20. There is. The light guide 33 drawn out from the LED housing case 32 is installed so as to extend forward along the upper surface of the standing wall 23A located above the standing wall 23 of the inside handle bezel 21 (hereinafter,). The portion extending forward from the LED housing case 32 is referred to as the first strategy unit 34). As shown in FIG. 4, the vertical wall 23A of the inside handle bezel 21 is provided with a slit 25 extending in the front-rear direction, and the light guide body 33 (first steering unit 34) is provided in the vehicle interior (from the slit 25). It is installed by a fixing member (not shown) so as to face the handle accommodating portion 20). Then, the light emitted from the light guide body 33 (first arrangement unit 34) irradiates the light toward the inside of the handle accommodating portion 20 through the slit 25.

In this case, since the viewer sits behind the steering wheel accommodating portion 20 in the front-rear direction of the vehicle, the line of sight L heads forward, that is, toward the traveling direction of the vehicle (see FIG. 1). On the other hand, the light traveling inside the light guide 33 in the first control unit 34 goes from the rear to the front. That is, the traveling direction of the light is substantially the same as the direction of the line of sight L of the viewer. In other words, the traveling direction of the light in the first strategy unit 34 is a direction away from the eyes of the viewer. Therefore, the light emitted from the slit 25 into the handle accommodating portion 20 has low luminosity factor for the viewer.

As shown in FIG. 2, the light guide body 33 extends to the front of the handle accommodating portion 20 and then is folded back toward the rear by the first folding portion (an example of the bending portion) 35 to form the upper board 12 and the lower board 13. It is installed so as to extend backward along the boundary portion of the above (hereinafter, the portion extending backward from the first turn-back portion 35 is referred to as a second steering unit 36).

As described above, the upper board 12 and the lower board 13 are fixed to the upper board 12 by superimposing a plurality of mounting pieces 13B protruding upward from the upper edge of the main body portion 13A of the lower board 13 on the outside of the passenger compartment of the upper board 12. By doing so, it is concluded. Specifically, the upper board 12 and the lower board 13 have a mounting boss erected on the outer surface of the passenger compartment of the upper board 12 inserted into a through hole formed in the mounting piece 13B of the lower board 13 and tightened with screws. It has a structure in which it is fixed to each other by using a fastening means such as thermal caulking (see FIG. 2). Of these, a groove-shaped recess 13C that extends in the direction along the edge of the main body 13A and is recessed outside the passenger compartment is formed at the extension base end portion of the mounting piece 13B from the main body 13A. The light guide body 33 can be accommodated inside the recess 13C. Further, in a state where the upper board 12 and the lower board 13 are assembled, a slit-shaped opening 17 is formed between the lower end edge of the upper board 12 and the upper end edge of the main body portion 13A of the lower board 13. (See Fig. 1).

The second arrangement portion 36 of the light guide body 33 arranged along the boundary portion between the upper board 12 and the lower board 13 is housed in the recess 13C of the mounting piece 13B so as to face the vehicle interior from the opening 17. It is installed in. Then, the upper surface 16A of the armrest 16 is irradiated by a part of the light emitted from the opening 17 toward the vehicle interior.

In this case as well, the line of sight L of the viewer goes forward (see FIG. 1). Further, the light emitted from the opening 17 is the light emitted from the front to the rear in the light guide 33. That is, the traveling direction of the light is opposite to the direction of the line of sight L of the viewer. In other words, the traveling direction of the light in the second distribution unit 36 of the light guide body 33 is a direction approaching the eyes of the viewer. Therefore, the luminosity factor of the light emitted from the opening 17 (light emitted from the second distribution unit 36) is the light emitted into the handle accommodating unit 20 (light emitted from the first distribution unit 34). Compared to the luminosity factor of, it is considered to be high (bright) for the viewer.

The light guide 33 extends to the rear end of the boundary between the upper board 12 and the lower board 13, and then is folded forward by the second folded portion 37 (an example of the bent portion), and is forward along the lower surface of the armrest 16. It is installed so as to extend toward. Further, it is installed so as to extend forward from the front end of the armrest 16 along the lower surface of the door grip 18 (hereinafter, the entire portion extending forward from the second folding portion 37 is referred to as a third arrangement portion 38. ). As described above, since the door grip 18 is provided so as to project from the lower board 13 so as to be separated from the vehicle interior side, the front portion of the third control unit 38 is pulled out from the back surface of the lower board 13 to the vehicle interior side. It is installed on the inner surface (the surface opposite to the design surface) of the tubular door grip 18.

Slit-shaped openings 19 are continuously provided on the lower surface of the armrest 16 and the lower surface of the door grip 18. The light guide body 33 (third arrangement unit 38) folded back by the second folding unit 37 is arranged so as to face the vehicle interior from the opening 19, and irradiates from the opening 19 toward the vehicle interior (downward). The pocket opening 27A of the door pocket 27 is irradiated with a part of the light emitted.

In this case as well, the line of sight L of the viewer goes forward (see FIG. 1). Further, the light emitted from the opening 19 toward the vehicle interior is the light emitted from the rear to the front in the light guide 33. That is, the traveling direction of the light is the same as the direction of the line of sight L of the viewer. In other words, the traveling direction of the light in the third strategy unit 38 is a direction away from the eyes of the viewer. Therefore, the luminosity factor of the light emitted from the opening 19 (light emitted from the third arrangement unit 38) is emitted from the light emitted from the opening 17 to the upper surface 16A of the armrest 16 (light emitted from the second arrangement unit 36). It is considered to be low (dark) for the viewer compared to the visual sensitivity of light).

After extending to the front end of the door grip 18, the light guide 33 is pulled back to the back surface (outer surface of the passenger compartment) of the trim board 11 (lower board 13) and is folded back toward the rear by the third folding portion 39. , It is fixed to the back surface of the lower board 13 while avoiding interference with other parts.

As described above, in the lighting structure of the present embodiment, in the first portion 11B (upper surface 16A of the armrest 16) where it is desired to provide bright illumination to the viewer, the traveling direction of the light traveling in the light guide 33 is determined. In the second portion 11D (handle accommodating portion 20 and pocket opening 27A), the light guide 33 is installed so as to be closer to the eyes of the viewer and may be darker than the first portion 11B to the viewer. Is a lighting device 30 (LED 31 and a light guide 33) installed so that the traveling direction of the light traveling in the light guide 33 is a direction away from the eyes of the viewer.

Next, the action and effect will be described. The lighting structure in the door trim 10 of the present embodiment includes an LED 31 and a longitudinal light guide body 33 capable of guiding the light emitted from the LED 31, and the light guide body 33 is bent in the longitudinal direction. It is provided with a 1-folding section 35 and a 2nd folding section 37, and guides the light from the LED 31 incident from one end 33A side to the other end 33B side while guiding the light internally. The door trim 10 is a portion that provides bright lighting to a viewer who gets on the vehicle, and a first portion 11B, which is a portion that provides bright lighting to the viewer, and a second portion that provides light to the viewer. The light guide body 33 includes a second portion 11D, which is a portion that provides darker illumination than the first portion 11B, and the light guide body 33 has a direction from one end 33A side toward the other end 33B side in the first portion 11B. It is installed so as to be close to the eyes of the viewer, and is installed so as to be away from the eyes of the viewer in the second portion 11D.

According to such a configuration, the direction in which the light guide body 33 is directed from one end 33A side to the other end 33B side (light traveling direction) is the first, even if a plurality of light sources and light guides having different brightness are not used. By installing the first portion 11B so as to be closer to the eyes of the viewer, the viewer is illuminated brightly, and in the second portion 11D, the second portion 11D is installed so as to be away from the eyes of the viewer. It is possible to illuminate the viewer darker than the first portion 11B. That is, it is possible to illuminate a plurality of points on the door trim 10 so as to have different visual sensitivities to the viewer.

In the above configuration, the light guide body 33 is installed so that the direction from one end 33A side to the other end 33B side is the direction from the front side to the rear side of the door trim 10 in the first portion 11B, and the second portion 11B. In the portion 11D, it is installed so as to be in the direction from the rear side to the front side.

Further, in the above configuration, the direction of the line of sight L of the viewer is the same as the traveling direction in the vehicle.
