  The present invention relates to a vehicle interior material.

  Conventionally, various types of vehicle interior materials provided with a lighting device provided in a vehicle have been proposed. For example, as in Patent Document 1, a structure is known in which a permeable skin material having a pattern is attached to the interior side of a lighting unit that emits light in a planar shape.

JP 2009-101840 A

  By the way, in order to increase the variation of the interior design and further enhance the design, it is conceivable to use not only a single shape lighting device but also various shapes of lighting devices.

  This invention was completed based on the above situations, Comprising: It aims at providing the interior material for vehicles which can improve the designability, using the illuminating device of various shapes combiningly. To do.

  In order to solve the above-described problems, an interior material for a vehicle according to the present invention is an interior material for a vehicle that includes a lighting device outside a vehicle interior of a translucent interior member, and the lighting device includes the interior member. A planar light emitting member disposed outside the passenger compartment, and a linear light emitting member disposed in a space formed between the planar light emitting member and the interior member so as to overlap the planar light emitting member. The space formed between the planar light emitting member and the interior member is provided with a wall portion extending along the longitudinal direction of the linear light emitting member, and is partitioned by the wall portion. The linear light emitting member is housed in the partitioned space.

  When the linear light emitting member and the planar light emitting member are arranged as an illuminating device on the outside of the vehicle interior of the translucent interior member, the light from the linear light emitting member is drowned out by the light from the planar light emitting member. There is a possibility that light from the light emitting member is not identified or difficult to identify. Therefore, in the present invention, a wall portion extending along the longitudinal direction of the linear light emitting member is provided, and the linear light emitting member is accommodated in a partitioned space partitioned by the wall portion. According to such a structure, it can suppress that the light emitted from a linear light emitting member spreads by the wall part to the surface direction (direction along the design surface) of a planar light emitting member, and a planar light emitting member light-emits. Even in this state, the linear light from the linear light-emitting member can be highlighted. As a result, on the design surface of the interior member, it is possible to clearly express the design of light having a composite of linear light and planar light, and the design of the interior member can be improved. It becomes.

  In the above configuration, the illumination device includes a plurality of the linear light emitting members, each linear light emitting member is accommodated in the partition space, and the adjacent partition spaces are separated from each other via a hollow space. It is good also as composition which has.

  In this way, by forming a hollow space between each compartment space in which each linear light emitting member is accommodated, light emission of the planar light emitting member is prevented between the compartment spaces (between the linear light emitting members). Will not exist. As a result, a dark portion is not generated in the light from the planar light emitting member, and it is possible to improve the design property by composite light.

  The said structure WHEREIN: While the said wall part is formed of the protrusion piece part which protrudes from the vehicle interior outer side of the said interior member, the said linear light emitting member may be made to be hold | maintained by the said protrusion piece part.

  In this way, by holding the linear light emitting member by the protruding wall portion provided on the interior member side, it is not necessary to provide a wall portion on the planar light emitting member side. If a wall portion is provided on the planar light emitting member side, unevenness due to the wall portion may occur on the light emitting surface of the planar light emitting member, so that it may be difficult to emit light uniformly. By providing the protruding piece portion on the interior member side, it becomes possible to cause the planar light emitting member to emit light uniformly.

  In the above configuration, the planar light emitting member may have a reflective layer on the linear light emitting member side.

  As described above, by providing the reflective layer on the linear light emitting member side of the planar light emitting member, the linear light emitting member emits light to the vehicle interior side (planar light emitting member side) of the vehicle interior side (linear light emitting member side). ) Can be reflected (returned). As a result, the light from the linear light-emitting member can be effectively used, and the linear light can be further emphasized.

  In the above configuration, the interior member includes a skin material constituting a design surface, a translucent member disposed on a vehicle interior side of the planar light emitting member, and between the skin material and the translucent member. And a design forming layer for forming a predetermined design on the vehicle interior side of the interior member, and the design forming layer is colorless and translucent at a position facing the linear light-emitting member. On the other hand, it is good also as what is colored except the position which opposes the said linear light-emitting member.

  According to such a configuration, by printing or coloring a pattern that is raised by light at a position other than the position facing the linear light-emitting member in the design forming layer, surface light emission by the planar light-emitting member can be achieved. Further design properties can be imparted, and the portions where the linear light-emitting members are arranged are colorless and translucent, so that light emission by the linear light-emitting members is not hindered.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the interior material for vehicles which can improve the designability, using light of various shapes in combination.

FIG. 1 is a diagram schematically showing a surface on the vehicle interior side (design surface side) of a door trim 10 according to Embodiment 1 of the present invention. The door trim 10 constitutes a portion of the vehicle door on the vehicle interior side, and is attached from the vehicle interior side to a door inner panel (not shown) provided in the vehicle door. Note that the left side of FIG. 1 is the front of the vehicle, and the right side of FIG. 1 is the rear of the vehicle.

  As shown in FIG. 1, the door trim 10 (vehicle interior material) has a generally flat plate shape (board shape) as a whole. The door trim 10 includes a trim board 12 and an ornament 20 (an interior member) attached to the trim board 12. Furthermore, the door trim 10 includes an armrest 14, a speaker grill 16, and the like.

  The trim board 12 is formed of a synthetic resin material or a material obtained by mixing natural fibers (such as kenaf) with a synthetic resin material. An ornament mounting hole (not shown) for mounting the ornament 20 is formed in the trim board 12.

  As shown in FIG. 1 and FIG. 2, the ornament 20 has a translucent base material 22 (translucent member) having a translucency, and a translucent skin disposed on the interior side of the translucent base material 22. It is comprised from the material 26 and the film layer (design formation layer) 28 distribute | arranged between the permeation | transmission base material 22 and the skin material 26. FIG. The skin material 26 covers substantially the entire vehicle interior side surface of the ornament 20 in a shape that conforms to the shapes of the transmissive substrate 22 and the film layer 28. The skin material 26 may be a material having translucency, and is appropriately selected from a synthetic resin sheet, a woven fabric, a non-woven fabric, and the like.

  The transmissive substrate 22 is made of a transparent (or translucent) thermoplastic resin material (for example, acrylic resin) formed into a predetermined shape in order to ensure translucency. As shown in FIGS. 2 and 3, the transmissive substrate 22 has a protruding piece 24 (wall) for holding (positioning or restricting movement) a light guide rod 43 (linear light-emitting lighting device 40) described later. Is formed. The protruding piece 24 is formed integrally with the transmissive base material 22, protrudes from the surface of the transmissive base material 22 outside the passenger compartment toward the planar light emitting lighting device 50 described later, and extends in the longitudinal direction of the light guide rod 43. It is comprised by the wall shape extended along. The protruding piece 24 forms a partitioned space 31 with a pair of adjacent ones, and the light guide rod 43 (linear light emitting illumination device 40) is accommodated in the partitioned space 31. These partition spaces 31 are formed according to the number of light guide bars 43 (linear light-emitting illuminating devices 40). In the present embodiment, three partition spaces 31 are formed. The adjacent partition spaces 31 formed by the protruding piece portions 24 are separated from each other via the hollow space 33. Further, as shown in FIG. 3, the lower protruding piece 24 </ b> A forming the partition space 31 is formed with an upward convex portion 25 at the end on the planar light emitting lighting device 50 side, and the light guide rod 43 has prevented moving to the planar light-emitting illuminating device 50 side.

  The film layer 28 is a design forming layer for forming a predetermined design (including a predetermined pattern and a colored pattern having no specific pattern) on the interior side of the ornament 20 and is partially colored PET. It is made of a light-transmitting sheet material such as a film. The film layer 28 is formed so as to cover almost the entire surface of the ornament 20. For example, the film layer 28 is colored except for the position facing the linear light emitting illumination device 40, and the position facing the linear light emitting illumination device 40 is colorless. Printing is applied. In other words, the position facing the linear light-emitting illumination device 40 is the colorless light-transmitting portion 29a, and almost completely transmits the light from the linear light-emitting illumination device 40, but other than the position facing the linear light-emitting illumination device 40. A colored light-transmitting portion 29b that is partially colored and printed so as to partially absorb light of a specific wavelength in order to color light from a planar light emitting illumination device 50 described later with a specific design pattern; Has been.

  An illuminating device including a linear light-emitting illuminating device 40 and a planar light-emitting illuminating device 50 is disposed on the outer side of the transmissive substrate 22 in the passenger compartment. As shown in FIG. 3, a space 35 for accommodating the linear light emitting illumination device 40 and the like is provided between the transmissive substrate 22 and the planar light emitting illumination device 50. As shown in FIG. 1, the linear light-emitting lighting device 40 includes an LED 41 and a light guide rod 43 that is arranged in a shape extending in the front-rear direction of the vehicle along the transmissive substrate 22 and can guide light from the LED 41. Consists of the subject.

  The LED 41 is a light source for introducing light into the light guide rod 43 and is accommodated in a case (not shown). The LED 41 is controlled to emit light by a control device (not shown) and is supplied with power from a power source such as a battery mounted on the vehicle.

  The light guide rod 43 is formed of a long light guide material having a substantially circular cross section and having flexibility. Here, the light guide material is a material that transmits light, such as acrylic resin. In addition, one end of the light guide rod 43 in the longitudinal direction is attached to the case, and the end face on the one end side is arranged to face the LED 41. Thereby, the end surface on the one end portion side attached to the case is a light incident surface on which the light emitted from the LED 41 is incident. The light incident from the light incident surface of the light guide bar 43 is guided by repeating total reflection inside the light guide bar 43. A part of the light guided inside the light guide bar 43 is emitted from the outer peripheral surface of the light guide bar 43 to the outside. Therefore, the entire light guide bar 43 serves as a linear light source and can illuminate the surroundings.

  As shown in FIG. 3, the planar light emitting illumination device 50 is formed of at least an LED substrate 51 fitted in the mounting recess 18 provided in the trim board 12 and a surface light guide 53. For example, an LED chip that emits white light is mounted on the LED substrate 51, and a necessary number of LED chips are appropriately mounted to illuminate the entire ornament 20. The LED board 51 is controlled to emit light by a control device (not shown) and is supplied with power from a power source such as a battery mounted on the vehicle.

  The surface light guide 53 is formed of a light transmission part 55 that extends at least over the entire surface of the ornament 20 and is disposed on the transmission base material 22 side, and a reflection part 57. The light transmission part 55 is configured by forming a light transmission hole 56 having a predetermined pattern in white PET, and has a shallow box shape in which the trim board 12 side is opened by bending the end part toward the trim board 12 side. ing. Further, the surface of the light transmissive portion 55 on the vehicle interior side (transparent substrate 22 side) forms a reflective surface 55A made of white PET, and at least at a position facing the light guide rod 43, the vehicle of the light guide rod 43 is provided. It is supposed that light toward the outdoor side (light transmission part 55 side) can be reflected.

  The reflection portion 57 is provided at a location facing the light transmission portion 55 in the trim board 12. The reflection part 57 is formed of a sheet-like material that reflects light, and the position where the light transmission part 55 is arranged is provided except that a hole is provided at a position corresponding to the mounting recess 18 of the trim board 12. Is provided on the entire surface. And the light guide spreading to the whole surface light guide part 53 is implement | achieved by irregularly reflecting the light from LED board 51 between the light transmissive part 55 and the reflection part 57. FIG. A plurality of light transmission holes 56 are formed through the light transmission portion 55. By emitting light from each of the light transmission holes 56, the surface light guide unit 53 becomes a planar light source that emits light in a planar shape as a whole, and can emit planar light toward the vehicle interior side. The formation pattern of the light transmission holes 56 is a substantially concentric pattern centered on the position facing the LED substrate 51, and the hole density is relatively larger toward the outer side of the circle (the inner side of the circle). The aperture density is smaller, and the light guide to the outside is realized by this configuration.

  Next, the operation of the door trim 10 of this embodiment will be described. First, attachment of the ornament 20 and the lighting device (the linear light emitting lighting device 40 and the planar light emitting lighting device 50) in the door trim 10 of the present embodiment will be described. First, the LED substrate 51 is fitted into the mounting recess 18 provided in the trim board 12. Then, the LED substrate 51 is connected to a control device or the like. The planar light emitting illumination device 50 is disposed on the trim board 12 by attaching the reflecting portion 57 and the light transmitting portion 55 to the trim board 12.

  On the other hand, the linear light emitting illumination device 40 is attached to the transmissive substrate 22. Specifically, the light guide bar 43 is accommodated in the partitioned space 31 partitioned by the protruding piece 24. In addition, a film layer 28 is attached to the transmissive substrate 22 and a skin material 26 is further attached. Then, the ornament 20 (interior member) is attached by fitting the transmissive base material 22 into the trim board 12 on which the planar light emitting illumination device 50 is arranged.

  Next, the illumination mechanism will be described. First, the illumination mechanism of the linear light emitting illumination device 40 will be described. When the LED 41 is turned on, light is incident from one end of the light guide bar 43 on the case side, and light is guided by repeating reflection inside the light guide bar 43. Then, a part of the light guided inside the light guide bar 43 is emitted to the outside from the outer peripheral surface of the light guide bar 43, so that the entire light guide bar 43 becomes a linear light source. Of the light emitted to the outside from the light guide rod 43, the light emitted to the outside of the vehicle interior is reflected to the interior of the vehicle interior by the reflection surface 55 </ b> A of the light transmission portion 55. Therefore, the amount of light emitted from the light guide rod 43 toward the vehicle interior side can be increased, and the light emitted from the linear light emitting illumination device 40 can be made to stand out.

  Of the light emitted from the light guide rod 43, the light directed toward the surface direction of the planar light emitting illumination device 50 (the direction along the design surface) is reflected or refracted by the projecting piece portion 24 of the transmissive substrate 22. By doing so, it does not spread in the surface direction and it becomes easy to go to the vehicle interior side. Therefore, the light emitted from the light guide bar 43 is suppressed from spreading in the surface direction, and most of the light from the light guide bar 43 is emitted toward the vehicle interior side. In the present embodiment, the surface direction of the planar light emitting lighting device 50 is, for example, a direction (upward or downward in FIG. 3) orthogonal to the vehicle interior / exterior direction.

  Next, the planar light emitting lighting device 50 will be described. When the LED chip of the LED substrate 51 is turned on, the light from the LED substrate 51 repeats irregular reflection in the surface light guide 53 as described above, so that the light spreads in the surface light guide 53 and the light is light. By emitting light from each light transmission hole 56 of the transmission part 55, surface emission is performed as a whole. The light generated by the surface emission is emitted toward the vehicle interior side, and the light spreads in the hollow space 33. At this time, since the hollow space 33 is an air layer, the light of the planar light emitting lighting device 50 is not hindered. Then, the light from the planar light emitting illumination device 50 passes through the transmissive substrate 22 and passes through the colored light transmitting portion 29b of the film layer 28 to become light of a predetermined color, so that the entire interior of the ornament 20 on the vehicle interior side is obtained. Will light up.

  By the way, in this embodiment, even when the planar light-emitting illuminating device 50 emits light, the linear light-emitting illuminating device 40 can emit light, and a light design can be configured in a composite manner with lines and surfaces. ing. Specifically, as described above, the light from the planar light emitting illumination device 50 is transmitted through the colored light transmitting portion 29b from the hollow space 33 to form planar light, while the linear light emitting illumination device 40 is configured as described above. Thus, since the spread of light in the surface direction is hindered, the linear light of the linear light-emitting illuminating device 40 can be made to stand out even when the planar light-emitting illuminating device 50 is emitting light. As a result, a composite light design can be realized.

  As described above, the door trim 10 of the present embodiment is a door trim 10 that includes a lighting device outside the light-transmitting ornament 20, and the lighting device is arranged outside the ornament 20. The planar light-emitting illuminating device 50 and the linear light-emitting illuminating device 40 (guide) arranged so as to overlap the planar light-emitting illuminating device 50 in the space 35 formed between the planar light-emitting illuminating device 50 and the ornament 20. And a space 35 formed between the planar light emitting illumination device 50 and the ornament 20 extends along the longitudinal direction of the linear light emitting illumination device 40 (light guide rod 43). The protruding piece portion 24 is provided, and the linear light-emitting illuminating device 40 (light guide rod 43) is accommodated in the partition space 31 partitioned by the protruding piece portion 24.

  According to the door trim 10 of the present embodiment, the protruding piece portion 24 extending along the longitudinal direction of the linear light-emitting illuminating device 40 (light guide rod 43) is provided, and the linear space is defined in the partitioned space 31 partitioned by the protruding piece portion 24. It was set as the structure which accommodates the light-emitting illuminating device 40 (light guide rod 43). According to such a configuration, the light emitted from the linear light-emitting illuminating device 40 (light guide rod 43) by the protruding piece portion 24 is directed to the surface direction of the planar light-emitting illuminating device 50 (the direction along the design surface). Spreading can be suppressed, and even when the planar light emitting illumination device 50 emits light, the linear light from the linear light emitting illumination device 40 (light guide rod 43) can be made to stand out. As a result, on the design surface of the ornament 20, it is possible to clearly express the light design having a combination of linear light and planar light, and the design of the ornament 20 can be enhanced. Become.

  In this embodiment, the illuminating device has a plurality of linear light-emitting illuminating devices 40, each linear light-emitting illuminating device 40 (light guide bar 43) is accommodated in each of the partitioned spaces 31, and the adjacent partitioned spaces 31 are In this configuration, the hollow spaces 33 are separated from each other. Thus, by forming the hollow space 33 between each partition space 31 in which each linear light-emitting illuminating device 40 (light guide rod 43) is accommodated, the space between the partition spaces 31 (the linear light-emitting illuminating device 40 ( In the space between the light guide rods 43), there is nothing that prevents the light emission of the planar light emitting illumination device 50. As a result, a dark portion is not generated in the light emitted from the planar light emitting illumination device 50, and the design property by the combined light can be improved.

  In the present embodiment, the partition space 31 is formed by the protruding piece portion 24 protruding from the outside of the passenger compartment of the ornament 20 (transparent base material 22), and the linear light-emitting lighting device 40 (light guide bar 43) protrudes. It is held by the piece 24. If it does in this way, it will become unnecessary to provide the wall part which forms the division space 31 in the planar light-emitting illuminating device 50 side. For this reason, the surface light emitting illumination device 50 can emit light uniformly.

  In the present embodiment, the planar light-emitting illuminating device 50 has the reflective layer 55A on the side of the linear light-emitting illuminating device 40 (light guide bar 43). Light emitted to the vehicle interior side (planar light emitting illumination device 50 side) can be reflected (returned) to the vehicle interior side (linear light emitting illumination device 40 side). As a result, the light from the linear light-emitting illuminating device 40 can be effectively utilized, and the linear light can be further emphasized.

  In the present embodiment, the ornament 20 includes a skin material 26 that constitutes a design surface, a transmissive substrate 22 disposed on the vehicle interior side of the planar light emitting lighting device 50, and between the skin material 26 and the transmissive substrate 22. And a film layer 28 for forming a predetermined design on the vehicle interior side of the ornament 20. The film layer 28 faces the linear light-emitting lighting device 40 (light guide rod 43). It has the colorless translucent part 29a in the position, and has the colored translucent part 29b other than the position facing the linear light-emitting illumination device 40 (light guide rod 43). By printing or coloring a pattern that is raised by light on the film layer 28, it becomes possible to give further designability to the planar light emission by the planar light emitting illumination device 50, and linear light emitting illumination. Since the portion where the device 50 is disposed is colorless and translucent, the light emission by the linear light emitting illumination device 40 is not hindered.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, the configuration of the partition space 131 is different from that in the above embodiment.

  In the present embodiment, the light guide bar 43 is held by the holding member 147 having translucency. The holding member 147 has a configuration in which a light-transmitting flat plate is bent in a zigzag shape, and the partition spaces 131 and the hollow spaces 133 are alternately arranged. The partition space 131 extends in a shape along the longitudinal direction of the light guide rod 43, and the space between the adjacent partition spaces 131 is a hollow space 133 that does not hinder the light emission of the planar light emitting illumination device 50.

  Further, in order to suppress the spread of light in the surface direction of the light guide bar 43, a reflective layer 145 is provided inside the holding member 147. In addition, since the vehicle interior side surface of the light transmissive portion 55 is the reflective surface 55A, the reflective layer 145 is not provided on the surface of the holding member 147 on the surface light emitting illumination device 50 side. Of the light emitted from the light guide bar 43, the light in the surface direction of the planar light emitting lighting device 50 is reflected by the reflective layer 145 and travels toward the vehicle interior side. Therefore, the linear light from the linear light emitting illumination device 40 can be more clearly identified.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.

  (1) In the above embodiment, the hollow space is provided between the linear light emitting members, but it is not always necessary to provide it. For example, as shown in FIG. 5, the partition spaces 231 formed by the protruding piece portions 224 may be arranged so that the light guide bars 43 (linear light-emitting lighting devices 40) are adjacent to each other.

  (2) In the said embodiment, although the door trim 10 was illustrated as an interior material for vehicles, it is not limited to this. For example, a back door trim or a roof trim can be exemplified as the vehicle interior material.

  (3) In the said embodiment, although LED41 and LED board 51 (LED chip) were illustrated as a light source, it is not limited to this. As the light source, in addition to the LED, for example, an incandescent bulb (bulb), a fluorescent tube, a halogen lamp, a metal halide lamp, a semiconductor laser (LD), a gas laser, an electroluminescent body, a plasma arc tube, and the like can be used.

  (4) In the above embodiment, the skin material 26 and the film layer 28 are used. That is, the ornament 20 (interior member) only needs to include at least a transmissive substrate.

(5) In the above embodiment, the film layer 28 having the colorless translucent portion 29a and the colored translucent portion 29b is formed as the design forming layer. For example, after forming a predetermined colored layer, the film layer 28 is led out of the colored layer. It is good also as what comprises the design formation layer which concerns on this invention by comprising as a notch part which notched the position facing the light rod 43 (linear light-emitting illuminating device 40) selectively. Alternatively, a method of selectively forming a colored light-transmitting portion other than the position facing the light guide rod 43 (linear light-emitting lighting device 40), for example, a method of forming a colored light-transmitting portion having a predetermined pattern by sputtering or the like. .
Moreover, in the film layer 28, you may provide a colored translucent part instead of the colorless translucent part 29a. That is, in the film layer 28, both a portion facing the light guide rod 43 and a portion not facing the light guide rod 43 may be used as the colored light-transmitting portions. In the case of such a configuration, the colored translucent part (first colored translucent part) facing the light guide bar 43 is made transparent, and the colored translucent part (second colored translucent part) not facing the light guide bar 43 is used. It is possible to make the linear light from the light guide bar 43 stand out.
In addition, as a structure for setting the translucency of the first colored translucent part to be higher than the translucency of the second colored translucent part, the first colored translucent part is a highly translucent color. And setting the second colored translucent part with a color that is less translucent than the first colored translucent part (for example, a color darker than the first colored translucent part) However, it is not limited to this configuration.

  (6) In the first embodiment, the protruding piece 24 is protruded from the transmissive base material 22, but the wall portion may be protruded from the planar light emitting lighting device.

  (7) In the above-described embodiment, the reflection unit 57 is provided in the surface light guide unit 53 of the planar light emitting lighting device 50. However, when the trim board 12 reflects light, the reflection unit 57 is not necessarily provided.

  (8) In the above-described embodiment, the surface light-emitting illumination device 50 includes the surface light guide 53 and the LED substrate 51 disposed on the back surface thereof. It may be a device. Moreover, as long as planar light can be obtained even with other illumination, a self-luminous illumination panel or other types may be used.

  (9) In the above embodiment, the planar light emitting illumination device 50 is arranged on almost the entire surface of the ornament 20, but the planar light emitting illumination device may be arranged facing a part of the ornament 20. In that case, the shape of the planar light-emitting illumination device may be rectangular, round, or other shapes. Thus, in the case where the planar light emitting illumination device is arranged facing a part of the ornament 20, the planar light emitting illumination device may be smaller than the linear light emitting illumination device. By holding the linear light-emitting illumination device on the protruding piece portion that protrudes from the transmissive substrate side, there is also an advantage that the assembly becomes easier than when the protruding piece portion is provided on the planar light-emitting illumination device side.

  (10) In the second embodiment, the reflective layer 145 is provided in order to suppress the spread of light in the surface direction of the linear light-emitting illuminating device 40. However, also in the first embodiment, the linear light-emitting illumination of the protruding piece portion is provided. A similar reflective layer may be provided on the device side to suppress the spread of light in the surface direction of the linear light emitting lighting device 40.
