Description

Technical Field

[0001] The present disclosure relates to an interior member with a skin material, which is used, for example, for the interior of a vehicle.

Background Art

[0002] In the field of vehicle interiors, the development of interior members with switches for operating equipment has been progressing. As an example, the lid of the console box in Patent Document 1 includes a skin material, a switch, and a base material from the front side to the back side. Further, the skin material includes a surface layer and a cushion layer from the front side to the back side.

[0003] On the surface of the surface layer, a design (a large number of light points arranged in a grid pattern) corresponding to the switch is displayed by a backlight. The operator can grasp the position of the switch by visually recognizing the design. Further, the operator can press the switch through the surface layer and the cushion layer by pressing the design.

[0004] The skin material bypasses the outer edge of the base material, that is, the lid, and is wound from the front surface to the back surface of the base material. The end of the skin material is joined to the back surface of the base material. The wiring connected to the switch bypasses the outer edge of the lid together with the skin material and is wound from the front surface to the back surface of the base material. Note that a cover member is adjacent to the lower side of the lid. The cover member covers the opening of the box body of the console box. The cover member does not protrude into the passenger compartment.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, if the wiring is routed around the outer edge of the lid, the routing length (the length of the wiring) becomes long. That is, the wiring becomes redundant. Also, the cushion layer is flexible. Therefore, if a switch is arranged on the back side of the cushion layer, the pressing force of the operator is easily absorbed by the cushion layer. As a result, it is difficult for the pressing force to be transmitted to the switch. Thus, when the switch is arranged on the back side of the cushion layer, the operability deteriorates. In this regard, when the switch is arranged on the front side of the cushion layer, the operability can be improved. However, if this is done, the wiring will also be arranged on the front side of the cushion layer. For this reason, it becomes easier for the operator to recognize the wiring through the surface layer by touch and vision. Therefore, the wiring that has no direct relation to the operation of the device will deteriorate the tactile sensation of the operator. Also, the appearance of the lid will deteriorate, impairing the design quality. Therefore, an object of the present disclosure is to provide an interior member that can suppress the redundancy of the wiring portion and the deterioration of the tactile sensation and improve the design quality.

Means for Solving the Problem

[0007] To solve the above problems, the interior member of the present disclosure includes a first skin material having a first exposed portion exposed indoors and a first buried portion buried from the first exposed portion to the outdoor side, a second skin material exposed indoors, having a second exposed portion adjacent to the first exposed portion, and a second buried portion buried from the second exposed portion to the outdoor side and joined to the first buried portion, a main body portion disposed directly behind the first exposed portion, and a transducer having a wiring portion disposed at least directly behind the first buried portion and electrically connected to the main body portion, wherein an end portion of the wiring portion is disposed on the outdoor side of the first buried portion.

Effect of the Invention

[0008] According to the interior member of the present disclosure, a wiring portion is arranged by utilizing a joint portion between a first skin material and a second skin material. Therefore, compared with the case where the wiring portion is arranged to bypass the outer edge of the interior member, it is possible to suppress the redundancy of the wiring portion. Further, since the redundancy of the wiring portion can be suppressed, it becomes difficult for an operator to touch the wiring portion through the first skin material, and it also becomes difficult to visually recognize the wiring portion. Therefore, it is possible to suppress a decrease in tactile sensation and improve the design quality.

Modes for Carrying Out the Invention

[0010] Hereinafter, embodiments of the interior member of the present disclosure will be described.

[0011] <First Embodiment> [Arrangement and Configuration of Interior Member] First, the arrangement and configuration of the interior member of the present embodiment will be described. In the subsequent figures, the rear side corresponds to the "indoor side" of the present disclosure, and the front side corresponds to the "outdoor side" of the present disclosure. FIG. 1 shows an arrangement diagram of the interior member of the present embodiment. FIG. 2 shows a rear view (front view) of the interior member after transmission. FIG. 3 shows a cross-sectional view taken along the direction III-III of FIG. 2. FIG. 4 shows an enlarged view within the frame IV of FIG. 3. FIG. 5 shows an enlarged view within the frame V of FIG. 3. In FIG. 2, for the convenience of explaining the positional relationship of each member, the display regions A1 to D1, the sensor unit 4, the light sources 90A to 90D, etc. are shown through the skin layer 200 and the like.

[0012] As shown in FIG. 1, the interior member 1 is disposed at the central portion in the left-right direction (vehicle width direction) of the instrument panel (interior part) 92 of the passenger compartment. That is, the interior member 1 is an interior member for a vehicle. As shown in FIGS. 2 to 5, the interior member 1 includes a first skin material 2, a second skin material 3, a sensor unit 4, a first stitch portion 5, a second stitch portion 6, a flexible portion 7, a base portion 8, and a light source portion 9.

[0013] (First skin material 2) The first skin material 2 includes a first exposed portion 20 and a first buried portion 21. The first exposed portion 20 is exposed in the passenger compartment (indoors). The first exposed portion 20 has a flexible sheet-like three-layer structure. That is, from the front side (rear side) to the back side (front side), the first exposed portion 20 includes a skin layer 200, an intermediate layer 201, and a design layer 202.

[0014] The skin layer 200 is made of synthetic leather and has a layered structure. The skin layer 200 has translucency and flexibility. The surface of the skin layer 200 is exposed in the passenger compartment. The intermediate layer 201 is disposed on the back side of the skin layer 200. The intermediate layer 201 is made of translucent ink and has a layered structure. The intermediate layer 201 has translucency and flexibility. The intermediate layer 201 has lower translucency than the skin layer 200. That is, the intermediate layer 201 is smoky semi-transparent. Also, the intermediate layer 201 is colored and transparent.

[0015] The design layer 202 is disposed on the back side of the intermediate layer 201. The design layer 202 is made of opaque ink and has a layered structure. The design layer 202 has opacity and flexibility. Four recesses 203A to 203D are arranged in the design layer 202. The design layer 202 (excluding the portion where the recesses 203A to 203D are arranged) does not transmit light.

[0016] The four recesses 203A to 203D open to the front and back surfaces of the design layer 202. That is, the recesses 203A to 203D penetrate the design layer 202 in the front-back direction. The inside of the recesses 203A to 203D is a space. The recesses 203A to 203D set display areas A1 to D1 in the first display portion 20. As shown in FIG. 2, when viewed from the front side, the display area A1 (recess 203A) forms the character "A", the display area B1 (recess 203B) forms the character "B", the display area C1 (recess 203C) forms the character "C", and the display area D1 (recess 203D) forms the character "D". As shown in FIGS. 3 and 5, in the first display portion 20, the portion where the display areas A1 to D1 (recesses 203A to 203D) are set is thinner in the front-back direction thickness compared to other portions. Therefore, light easily passes through. As shown in black in FIG. 1, the display areas A1 to D1 display predetermined designs "A" to "D" on the surface of the skin layer 200, that is, the first display portion 20, by the light irradiated from the back side.

[0017] The first buried portion 21 is buried forward from the upper edge of the first display portion 20. The first buried portion 21 does not protrude into the vehicle interior. The first buried portion 21 is integrally continuous with the first display portion 20. That is, the first buried portion 21 has a flexible sheet-like three-layer structure similar to the first display portion 20. The first buried portion 21 includes an epidermis layer 210, an intermediate layer 211, and a design layer 212 from the front side (upper side) to the back side (lower side). The epidermis layer 210 and the epidermis layer 200, the intermediate layer 211 and the intermediate layer 201, and the design layer 202 and the design layer 212 are each made of the same material and are integrally continuous.

[0018] (Second skin material 3) The second skin 3 is arranged on the upper side of the first skin 2. The second skin 3 is made of synthetic leather and has a sheet shape. The second skin 3 includes a second exposed portion 30 and a second buried portion 31. The second exposed portion 30 is exposed to the interior of the vehicle cabin. The second exposed portion 30 is adjacent to the upper side of the first exposed portion 20.

[0019] The second buried portion 31 is buried forward from the lower edge of the second exposed portion 30. The second buried portion 31 is not exposed inside the vehicle cabin. The second buried portion 31 is integrally connected to the second exposed portion 30. The second buried portion 31 is disposed above the first buried portion 21. As described later, the second buried portion 31 is joined to the first buried portion 21.

[0020] (Sensor part 4) The sensor unit 4 is disposed on the rear side of the first exposed portion 20 and the rear side of the first buried portion 21. The sensor unit 4 includes four sensors (switches for operating the device) 4A to 4D. First, the configurations of the four sensors 4A to 4D will be described. The four sensors 4A to 4D have the same configuration. Below, the configuration of sensor 4A will be described as a representative.

[0021] The sensor 4A is a capacitance type pressure sensor (load sensor). The sensor 4A can detect a load (pressing force of an operator) input from the front side (inside of the vehicle compartment). The load is included in the concept of a "physical quantity" in this disclosure. The sensor 4A includes a main body 40 and a wiring portion 41.

[0022] The main body 40 is disposed on the back side of the first exposed portion 20. As shown in FIG. 2, the main body 40 is annular when viewed from the front side. The main body 40 is a flexible sheet having a three-layer structure. That is, as shown in FIG. 3 and FIG. 5, the main body 40 includes a front electrode layer 400, an insulating layer 401, and a rear electrode layer 402 from the front side to the rear side. The front electrode layer 400 is disposed on the rear side of the design layer 202. The front electrode layer 400 is layered and flexible. The front electrode layer 400 includes a styrene-based thermoplastic elastomer and a conductive material including carbon black.

[0023] The insulating layer 401 is disposed on the back side of the front side electrode layer 400. The insulating layer 401 is layered and has flexibility. The insulating layer 401 has a styrene-based elastomer and an olefin-based elastomer. The back side electrode layer 402 is laminated on the back side of the insulating layer 401. The back side electrode layer 402 is layered and has flexibility. The back side electrode layer 402 is made of the same material as the front side electrode layer 400.

[0024] As shown in FIGS. 2, 3, and 5, input regions A2 to D2 are set in the main body portion 40. The input regions A2 to D2 extend over the entire main body portion 40. When viewed from the front side, the input regions A2 to D2 are annular. When viewed from the front side, the input regions A2 to D2 are arranged around the display regions A1 to D1. A load is input from the front side to the input regions A2 to D2. Due to the load, the insulating layer 401 is elastically deformed, and the distance between the electrodes (the front-back direction distance between the front side electrode layer 400 and the back side electrode layer 402) changes. That is, the capacitance changes.

[0025] As shown by the dotted line in FIG. 1, the wiring portion 41 is disposed on the back side of the first exposed portion 20 and the back side of the first buried portion 21. As shown in FIG. 2, when viewed from the front side, the wiring portion 41 is strip-shaped. The wiring portion 41 is integrally continuous with the main body portion 40. That is, as shown in FIGS. 3 and 4, the wiring portion 41 has a flexible sheet-like three-layer structure similar to the main body portion 40. The wiring portion 41 includes a front side wiring layer 410, an insulating layer 411, and a back side wiring layer 412 from the front side toward the back side. The front side wiring layer 410 and the front side electrode layer 400, the insulating layer 411 and the insulating layer 401, and the back side wiring layer 412 and the back side electrode layer 402 are each made of the same material and are integrally continuous.

[0026] As shown in FIGS. 1 and 3, one end portion (rear end portion) of the wiring portion 41 is continuous with the main body portion 40. On the other hand, a connector 41a is disposed at the other end portion (front end portion) of the wiring portion 41. The connector 41a corresponds to the "end portion of the wiring portion" of the present disclosure. The connector 41a is disposed in front of the first buried portion 21, the second buried portion 31, and the flexible portion 7.

[0027] A control device (not shown) is arranged on the front side of the interior member 1. The connector 41a (specifically, the front wiring layer 410 and the back wiring layer 412) is electrically connected to the control device via the harness 91.

[0028] Next, the arrangement of the four sensors 4A to 4D will be described. As shown by the dotted line in FIG. 1, the main body portions 40 of the four sensors 4A to 4D are arranged at predetermined intervals in the vertical and horizontal directions. Also, the wiring portions 41 of the four sensors 4A to 4D are spaced apart at predetermined intervals in the left-right direction and extend in the vertical direction on the back side of the first exposed portion 20. Further, the wiring portions 41 of the four sensors 4A to 4D are spaced apart at predetermined intervals in the left-right direction and extend in the front-rear direction on the back side of the first buried portion 21.

[0029] (First stitch portion 5) The first stitch portion 5 is made of thread. The first stitch portion 5 extends in the left-right direction, similar to the second stitch portion 6 shown in FIG. 2. As shown in FIG. 4, the first stitch portion 5 stitches the wiring portion 41, the first buried portion 21, and the second buried portion 31 from the lower side to the upper side. Specifically, the first stitch portion 5 stitches (joins) the first buried portion 21 and the second buried portion 31. The first buried portion 21 and the second buried portion 31 joined to each other form a buried joint portion O. Also, the first stitch portion 5 stitches the wiring portion 41 to the back surface of the first buried portion 21. That is, the wiring portion 41 is positioned and fixed with respect to the first buried portion 21.

[0030] (Second stitch portion 6) The second stitch portion 6 is made of thread. As shown in FIG. 2, the second stitch portion 6 extends in the left-right direction. As shown in FIG. 4, the second stitch portion 6 stitches the wiring portion 41 and the first exposed portion 20 from the front side (back side) to the rear side (front side). Specifically, the second stitch portion 6 stitches the wiring portion 41 to the back surface of the first exposed portion 20. That is, the wiring portion 41 is positioned and fixed with respect to the first exposed portion 20.

[0031] As shown in FIG. 2, when viewed from the front side, the second stitch portion 6 is disposed between the boundary E between the first exposed portion 20 and the second exposed portion 30 and the main body portion 40. As shown in FIG. 4, the second stitch portion 6 protrudes rearward (toward the interior of the vehicle) with respect to the surface of the first exposed portion 20. When viewed from the rear side, the second stitch portion 6 has a long dotted line shape in the left-right direction. When the operator touches the first exposed portion 20, the epidermal layer 200 and the second stitch portion 6 can be distinguished by touch. That is, the second stitch portion 6 can be recognized by touch from the front side of the first exposed portion 20.

[0032] (Flexible portion 7) The flexible portion 7 includes a first flexible layer 70 and a second flexible layer 71. The first flexible layer 70 is disposed on the back side of the first epidermal material 2 and the sensor portion 4. The first flexible layer 70 is made of a foam of a thermoplastic elastomer. The first flexible layer 70 is in a layer form and has flexibility.

[0033] As shown in FIGS. 2 and 3, four through holes 700A to 700D are formed in the first flexible layer 70. The through holes 700A to 700D also serve as the "through holes" and "light introduction holes" of the present disclosure. The through holes 700A to 700D penetrate the first flexible layer 70 in the front-back direction.

[0034] As shown in FIGS. 2, 3, and 5, first regions A3 to D3 and second regions A4 to D4 are set in the first flexible layer 70. The first regions A3 to D3 are disposed on the back side of the input regions A2 to D2. When viewed from the front side, the first regions A3 to D3 have an annular shape. When viewed from the front side, the first regions A3 to D3 are disposed around the display regions A1 to D1.

[0035] The second regions A4 to D4 are adjacent to the first regions A3 to D3. When viewed from the front side, the second regions A4 to D4 are disposed radially inward of the first regions A3 to D3. The second regions A4 to D4 are disposed on the back side of the display regions A1 to D1. The second regions A4 to D4 correspond to the through holes (spaces) 700A to 700D.

[0036] Here, the first regions A3 to D3 are harder than the second regions A4 to D4. That is, the first regions A3 to D3 are the high-hardness region H. Also, the second regions A4 to D4 are the low-hardness region L, which is lower in hardness than the high-hardness region H. Note that the "hardness" is, for example, the hardness measured with an Asker C durometer (specified by SRISO101 (Japanese Rubber Association Standard Specification)). The second flexible layer 71 is disposed on the back side of the second skin material 3. The second flexible layer 71 is in a layer form and has flexibility. The second flexible layer 71 is made of the same material as the first flexible layer 70.

[0037] (Base 8, Light source unit 9) The base 8 includes a first base material 80 and a second base material 81. The first base material 80 is disposed on the back side of the first flexible layer 70. The first base material 80 is made of resin and has a layer form. The first base material 80 has translucency and flexibility. The second base material 81 is disposed on the back side of the second flexible layer 71. The second base material 81 is in a layer form and is made of the same material as the first base material 80.

[0038] The light source unit 9 is disposed on the back side of the base 8. As shown in FIGS. 2 and 3, the light source unit 9 includes four light sources (LEDs) 90A to 90D. The light sources 90A to 90D are respectively disposed on the back side of the through holes 700A to 700D. The surfaces of the light sources 90A to 90D can emit light entirely.

[0039] As an example, focusing on the display area C1, as shown in FIG. 5, the light from the light source 90C reaches the display area C1 through the base 8 and the through hole 700C. The light reaches the surface of the interior member 1 through the display area C1 (recess 203C), the intermediate layer 201, and the skin layer 200. Therefore, as shown in FIG. 1, the design "C" is displayed on the surface of the interior member 1.

[0040] [Operation method of interior member] Next, an operation method of the interior member of the present embodiment will be described. The interior member of the present embodiment is particularly suitable when an operator operates the interior member 1 in a state where it cannot be visually recognized. For example, it is suitable when a vehicle driver operates an interior member (specifically, a device associated with the interior member) while driving.

[0041] During the operation, the operator touches the surface of the interior member 1 without visually recognizing the interior member 1. Here, the second stitch portion 6 and the first exposed portion 20 (specifically, the skin layer 200) are made of different materials. Also, as shown in FIG. 4, the second stitch portion 6 (specifically, the rear end portion of the second stitch portion 6) protrudes from the surface of the first exposed portion 20. Therefore, the operator can recognize the second stitch portion 6 by touch.

[0042] As shown in FIG. 2, the second stitch portion 6 is disposed adjacent to the upper side of the input regions A2 to D2. Also, the operator has previously grasped the positional relationship between the second stitch portion 6 and the input regions A2 to D2. Therefore, the operator can recognize (search for) the positions of the desired input regions A2 to D2 by groping based on the position of the second stitch portion 6 recognized by touch.

[0043] In addition, as shown in FIG. 5, the first regions A3 to D3 directly behind the input regions A2 to D2 are high-hardness regions H. On the other hand, the second regions A4 to D4 adjacent to the first regions A3 to D3 are low-hardness regions L. Therefore, the operator can recognize the positions of the desired input regions A2 to D2 by groping based on the hardness difference between the high-hardness region H and the low-hardness region L.

[0044] When the operator can visually recognize the interior member and the light sources 90A to 90D are lit, the operator can recognize the positions of the desired input regions A2 to D2 based on the designs "A" to "D" displayed on the surface of the first exposed portion 20.

[0045] When the operator presses the desired input areas A2 to D2 (specifically, the part of the surface of the first display unit 20 where the desired input areas A2 to D2 are arranged on the back side), the main bodies (load detection parts) 40 of the sensors 4A to 4D corresponding to the input areas A2 to D2 are compressed. Therefore, the capacitance of the main body 40 increases. The control device drives a device (not shown) associated with the main body 40 based on the change in the capacitance of the main body 40. In this way, the interior member 1 of the present embodiment is operated.

[0046] [Function and Effect] Next, the function and effect of the interior member of the present embodiment will be described. Assume a case where the skin material is an integral body and the wiring part is arranged up to the outside of the vehicle compartment of the interior member. In this case, it is necessary to arrange the wiring part via the outer edge of the skin material. For example, when the first skin material 2 and the second skin material 3 shown in FIG. 3 are integrally connected in the vertical direction, it is necessary to arrange the wiring part 41 via the lower edge of the first skin material 2 or the upper edge of the second skin material 3.

[0047] On the other hand, in the case of the interior member 1 of the present embodiment, as shown in FIG. 3, the skin material is composed of two divided bodies (the first skin material 2 and the second skin material 3). Therefore, using the boundary (joint part, seam) E between the first skin material 2 and the second skin material 3, the wiring part 41 can be arranged up to the outside of the vehicle compartment of the interior member 1 (the outside of the vehicle compartment of the first buried part 21, the second buried part 31, the first flexible layer 70, and the second flexible layer 71). Therefore, compared with the case where the skin material is an integral body, the arrangement length can be shortened. Thus, the redundancy of the wiring part 41 can be suppressed. In addition, the influence (such as a decrease in detection accuracy) of noise (electrical resistance, stray capacitance, etc.) caused by the redundancy of the wiring part 41 on the sensor part 4 can be suppressed.

[0048] Also, as shown in FIGS. 3 and 5, the front-side electrode layer 400 is arranged directly behind the design layer 202. That is, the main body 40 is arranged directly behind the first skin material 2 without passing through other layers (such as a flexible layer). Therefore, the pressing force of the operator is easily transmitted to the main body 40. Therefore, the operability can be improved.

[0049] Here, when the main body portion 40 is disposed behind the first skin material 2, as shown in FIG. 4, the wiring portion 41 is also disposed behind the first skin material 2. That is, the wiring portion 41 that has no direct relation to the operation of the device will reduce the tactile sensation of the operator. In this regard, according to the interior member 1 of the present embodiment, as described above, the redundancy of the wiring portion 41 can be suppressed. For this reason, when the operator touches the interior member 1, it is difficult to recognize the wiring portion 41. Therefore, even though the wiring portion 41 is disposed behind the first skin material 2, the tactile sensation of the operator is hardly reduced. Further, since the redundancy of the wiring portion 41 can be suppressed, the contour of the wiring portion 41 hardly appears (is not conspicuous) on the surface of the first skin material 2. For this reason, it is difficult for the operator to visually recognize the wiring portion 41 through the first skin material 2. Therefore, even though the wiring portion 41 is disposed behind the first skin material 2, the design property of the interior member 1 can be improved.

[0050] Further, as shown in FIG. 3, the sensor portion 4 is disposed on the back side of the first skin material 2. For this reason, while preventing the sensor portion 4 from being visually recognized from the passenger compartment, the position of the sensor portion 4 can be recognized by touch. And the sensor portion 4 can be operated.

[0051] Further, as shown in FIG. 4, the first stitch portion 5 stitches the first buried portion 21 and the second buried portion 31. For this reason, the first buried portion 21 and the second buried portion 31 can be fixed. Further, the first stitch portion 5 stitches the wiring portion 41 to the first buried portion 21. For this reason, the wiring portion 41 can be fixed to the first buried portion 21. Further, the extending direction (left - right direction) of the first stitch portion 5 and the extending direction (front - rear direction) of the wiring portion 41 intersect (are orthogonal) to each other. For this reason, the length of the sewing margin can be shortened. Therefore, an increase in the wiring resistance can be suppressed. Further, the first stitch portion 5 is disposed at the buried joint portion O (specifically, the rear end of the buried joint portion O). The first stitch portion 5 does not protrude into the passenger compartment. For this reason, it looks good.

[0052] As shown in FIG. 4, the second stitch portion 6 is disposed on the first exposed portion 20. The operator can recognize the second stitch portion 6 by touch. Therefore, the operator can recognize the position of the desired input area A2 to D2 based on the position of the second stitch portion 6 recognized by touch. The second stitch portion 6 is also in the form of a dotted line. Therefore, the operator can easily recognize the second stitch portion 6 by touch.

[0053] As shown in Fig. 4, the second stitch portion 6 sews the wiring portion 41 to the first exposed portion 20. This allows the wiring portion 41 to be fixed to the first exposed portion 20. The extension direction (left-right direction) of the second stitch portion 6 and the extension direction (up-down direction) of the wiring portion 41 intersect (are perpendicular) with each other. This allows the length of the seam allowance to be shortened. This makes it possible to suppress an increase in wiring resistance.

[0054] 3, the connector 41a is disposed on the outer side of the vehicle cabin than the flexible portion 7. That is, the wiring portion 41 is routed by utilizing the boundary between the first flexible layer 70 and the second flexible layer 71. Therefore, it is possible to suppress redundancy of the wiring portion 41 compared to a case where the wiring portion 41 is routed around the flexible portion 7. Also, it is possible to suppress the influence of noise caused by redundancy of the wiring portion 41 on the sensor portion 4.

[0055] 2, 3, and 5, the first regions A3 to D3 directly behind the input regions A2 to D2 are high hardness regions H. On the other hand, the second regions A4 to D4 adjacent to the first regions A3 to D3 are low hardness regions L. The operator can recognize the hardness difference between the high hardness region H and the low hardness region L by touch from the front side of the first exposing portion 20. Therefore, the operator can recognize the position of the desired input region A2 to D2 based on the hardness difference.

[0056] Also, as shown in FIGS. 2, 3, and 5, the second regions A4 to D4 (low hardness regions L) are provided with through holes 700A to 700D. The through holes 700A to 700D penetrate the second regions A4 to D4 in the front-rear direction. Therefore, the hardness of the second regions A4 to D4 can be easily reduced.

[0057] Also, on the back side of the through holes 700A to 700D, light sources 90A to 90D are arranged via the first base material 80. Further, on the front side of the through holes 700A to 700D, display regions A1 to D1 are arranged. Therefore, the light from the light sources 90A to 90D can be irradiated onto the display regions A1 to D1 from the back side. Thus, the through holes 700A to 700D have a function as "light introduction holes" for introducing light into the display regions A1 to D1.

[0058] Also, as shown in FIGS. 3 and 5, the first exposed portion 20 includes a translucent intermediate layer 201. Therefore, when the light sources 90A to 90D are off (extinguished), it is possible to suppress the designs "A" to "D" of the display regions A1 to D1 from being displayed on the surface of the first exposed portion 20. On the other hand, when the light sources 90A to 90D are on (lit), it is possible to assist the designs "A" to "D" of the display regions A1 to D1 from being displayed on the surface of the first exposed portion 20.

[0059] Also, as shown in FIGS. 3 and 5, a first flexible layer 70 is arranged on the back side of the sensor unit 4. The first flexible layer 70 is made of an elastomer and has flexibility. Therefore, the touch feeling when the operator touches the first skin material 2 is good. Further, through holes 700A to 700D are formed in the first flexible layer 70. Therefore, the first flexible layer 70 has high light transmittance.

[0060] Also, as shown in FIGS. 3 and 5, a first base material 80 is disposed on the back side of the first flexible layer 70. The first base material 80 has translucency. Therefore, the light from the light sources 90A to 90D can be transmitted to the through holes 700A to 700D of the first flexible layer 70. Further, the base portion 8 is harder than the other portions (the first skin material 2, the second skin material 3, the sensor portion 4, the first stitch portion 5, the second stitch portion 6, the flexible portion 7). Therefore, the shape retention of the interior member 1 can be ensured.

[0061] Also, as shown in FIGS. 3 and 5, the light sources 90A to 90D and the through holes 700A to 700D are linearly connected in the front-back direction. Therefore, it has high translucency. Further, the light sources 90A to 90D are LEDs. Therefore, the light from the light sources 90A to 90D has high rectilinearity (directivity). Thus, it is easy to introduce light into the through holes 700A to 700D.

[0062] Also, the front conductive layer (front electrode layer 400, front wiring layer 410) and the back conductive layer (back electrode layer 402, back wiring layer 412) have a styrene-based thermoplastic elastomer as an elastomer component. That is, the conductive layer (front conductive layer, back conductive layer) has an elastomer component as a base material. Therefore, it is flexible.

[0063] <Second Embodiment> The difference between the interior member of the present embodiment and the interior member of the first embodiment is that the first stitch portion is not disposed. Further, the second stitch portion does not fix the wiring portion to the first exposed portion. Here, only the differences will be described.

[0064] FIG. 6 shows a vertical partial cross-sectional view of the interior member of the present embodiment. Note that the parts corresponding to those in FIG. 4 are denoted by the same reference numerals. As shown in FIG. 6, the first stitch portion 5 (see FIG. 4) is not disposed at the buried joint portion O. The surface of the first buried portion 21 (skin layer 210) and the surface of the second buried portion 31 are adhered. Further, the surface of the wiring portion 41 (front wiring layer 410) is adhered to the back surface of the first buried portion 21 (design layer 212).

[0065] The second stitch portion 6 is a stitch-shaped molded product. That is, the second stitch portion 6 is a pseudo stitch. The second stitch portion 6 is fixed to the surface of the first exposed portion 20 (skin layer 200). The second stitch portion 6 protrudes from the surface of the first exposed portion 20. The surface of the wiring portion 41 (front-side wiring layer 410) is adhered to the back surface of the first exposed portion 20 (design layer 202).

[0066] Regarding the parts with common configurations, the interior member of the present embodiment and the interior member of the first embodiment have the same operational effects. Similar to the interior member 1 of the present embodiment, the first stitch portion may not be arranged. That is, at the buried joint portion O, the first buried portion 21 and the second buried portion 31 may be adhered. Also, the wiring portion 41 may be adhered to the first buried portion 21. By doing so, the sewing allowance caused by the first stitch portion can be eliminated from the wiring portion 41. Therefore, an increase in wiring resistance can be suppressed.

[0067] The second stitch portion 6 may be a pseudo stitch. The wiring portion 41 may be adhered to the first exposed portion 20. By doing so, the sewing allowance caused by the second stitch portion 6 can be eliminated from the wiring portion 41. Therefore, an increase in wiring resistance can be suppressed. Even in this case, the operator can recognize the second stitch portion 6 by touch.

[0068] <Third Embodiment> The difference between the interior member of the present embodiment and the interior member of the first embodiment is that the first region corresponds to a low-hardness region and the second region corresponds to a high-hardness region. Here, only the differences will be described.

[0069] FIG. 7 shows a vertical cross-sectional view of the interior member of the present embodiment. Note that the parts corresponding to those in FIG. 5 are denoted by the same reference numerals. As shown in FIG. 7, the first flexible layer 70 includes a hard portion 701 and a soft portion 702. Both the hard portion 701 and the soft portion 702 are made of elastomer. The hard portion 701 has a higher hardness than the soft portion 702. That is, a hardness difference is set between the hard portion 701 and the soft portion 702.

[0070] When viewed from the front side, the soft portion 702 has an annular shape. The soft portion 702 is disposed in the first region C3. Therefore, the first region C3 is a low-hardness region L. On the other hand, the hard portion 701 is disposed in a portion other than the soft portion 702 in the first flexible layer 70. Therefore, the second region C4 is a high-hardness region H. The hard portion 701 has translucency. Therefore, the light from the light source 90C can pass through the hard portion 701.

[0071] Regarding the parts with the same configuration, the interior member of the present embodiment and the interior member of the first embodiment have the same operational effects. The first region C3 may be a low-hardness region L like the interior member 1 of the present embodiment. Also, the second region C4 may be a high-hardness region H. Even in this case, the operator can recognize the input region C2 by touch.

[0072] Further, when the operator applies a pressing force to the input region C2 via the first exposed portion 20, the first region C3 (low-hardness region L) is compressed and deformed (sinks) toward the back side. At this time, the second region C4 (high-hardness region H) guides the compression deformation of the first region C3 from the radially inner side. Therefore, the deformation direction of the first region C3 is likely to be stable.

[0073] <Others> The embodiments of the interior member of the present disclosure have been described above. However, the embodiments are not particularly limited to the above forms. It is also possible to implement in various modified forms and improved forms that those skilled in the art can perform.

[0074] [Regarding the configuration] FIG. 8(A) shows a vertical partial cross-sectional view of an interior member of another embodiment (Embodiment 1). FIG. 8(B) shows a vertical partial cross-sectional view of an interior member of another embodiment (Embodiment 2). FIG. 8(C) shows a vertical partial cross-sectional view of an interior member of another embodiment (Embodiment 3). Note that the parts corresponding to those in FIG. 7 are denoted by the same reference numerals. Also, the parts shown in FIGS. 8(A) to 8(C) correspond to those within the frame VIII in FIG. 7.

[0075] As shown in FIG. 8(A), the first flexible layer 70 of another embodiment (the first one) includes a hard portion 701 and a soft portion 702. The soft portion 702 is made of an elastomeric foam. The hard portion 701 is integrally connected to the soft portion 702. In the hard portion 701, the foam forming the soft portion 702 is impregnated with resin. That is, the hard portion 701 is made of a foam impregnated with resin. According to this embodiment, by partially impregnating the first flexible layer 70 with resin, the high-hardness region H (the second region C4) and the low-hardness region L (the first region C3) can be easily set. Note that the impregnation amount of the resin into the hard portion 701 is not particularly limited. Also, the soft portion 702 (the low-hardness region L) may be impregnated with resin. It is only necessary to set a difference in resin impregnation rate between the hard portion 701 and the soft portion 702.

[0076] As shown in FIG. 8(B), the first flexible layer 70 of another embodiment (the second one) includes a thin portion 703 and a thick portion 704. The thin portion 703 has a smaller thickness in the front-back direction than the thick portion 704. For this reason, the thin portion 703 has a lower hardness than the thick portion 704. Therefore, the thin portion 703 corresponds to the low-hardness region L and the thick portion 704 corresponds to the high-hardness region H, respectively. According to this embodiment, by partially reducing the thickness of the first flexible layer 70 in the front-back direction, the high-hardness region H (the first region C3) and the low-hardness region L (the second region C4) can be easily set. Note that the thickness of the thick portion 704 (the high-hardness region H) in the front-back direction may be reduced with respect to the original thickness of the first flexible layer 70 in the front-back direction. It is only necessary to set a difference in thickness in the front-back direction between the thin portion 703 and the thick portion 704.

[0077] As shown in FIG. 8(C), a plurality of through-holes 700C are formed in the first flexible layer 70 of another embodiment (the third one). The through-holes 700C penetrate the first flexible layer 70 in the front-back direction (front-rear direction). According to this embodiment, by partially arranging the through-holes 700C in the first flexible layer 70, it is possible to easily set a high-hardness region H (first region C3) and a low-hardness region L (second region C4). Note that the through-holes 700C may be arranged in the high-hardness region H. Further, the aperture diameter, the number of arrangements, and the shape of the through-holes 700C are not particularly limited. It is only necessary to be able to set the difference in the opening ratio of the through-holes 700C between the high-hardness region H and the low-hardness region L.

[0078] The type of stitch of the first stitch portion 5 shown in FIG. 4 is not particularly limited. For example, it may be a straight stitch, a chain stitch, a milling stitch, a blanket stitch, a French knot stitch, a cross stitch, a back stitch, an outline stitch, a feather stitch, a herringbone stitch, a cording stitch, a chevron stitch, or the like. The number of arrangements of the first stitch portion 5 is not particularly limited. It may be single (single stitch) or plural (for example, double stitch). The same applies to the second stitch portion 6.

[0079] The first stitch portion 5 shown in FIG. 4 may be combined in the form shown in FIG. 6. That is, the first buried portion 21 and the second buried portion 31 may be adhered, the wiring portion 41 may be adhered to the first buried portion 21, and the wiring portion 41, the first buried portion 21, and the second buried portion 31 may be stitched together by the first stitch portion 5. In this way, the bonding strength between the wiring portion 41 and the first buried portion 21, and between the first buried portion 21 and the second buried portion 31 is increased.

[0080] As shown in FIG. 4, the first stitch portion 5 has both a function as an "outer skin material joining member" that joins the first outer skin material 2 and the second outer skin material 3, and a function as a "first wiring portion fixing member" that fixes the wiring portion 41 to the first outer skin material 2. Further, the second stitch portion 6 has a function as a "second wiring portion fixing member" that fixes the wiring portion 41 to the first outer skin material 2. Staplers, rivets, or the like may be used as these "outer skin material joining members", "first wiring portion fixing members", and "second wiring portion fixing members".

[0081] Further, the second stitch portion 6 has a function as an "input position notification member" that indirectly notifies the operator of the positions of the input areas A2 to D2. For example, the second stitch portion 6 (pseudo stitch) shown in FIG. 6 does not have a function as a "second wiring portion fixing member" and only has a function as an "input position notification member". As the "input position notification member", a predetermined design may be three-dimensionally arranged on the surface of the first exposed portion 20. Even in this case, the operator can recognize the design by touch. Also, as the "input position notification member", a predetermined design may be arranged flatly. Even in this case, by setting a difference in coefficient of friction between the surface of the design and the surface of the first exposed portion 20, the operator can recognize the design by touch.

[0082] Here, examples of the design arranged as the "input position notification member" include a design including one or more selected from patterns (such as polka dot patterns, stripe patterns, lattice patterns, wavy patterns, marble patterns, etc.), characters (alphabets, hiragana, katakana, Chinese characters, numbers, Braille, etc.), figures (points, straight lines, dotted lines, dashed lines, polygons, circles, etc.), symbols (buttons for operating equipment, icons indicating the state of equipment, etc.).

[0083] Note that the second stitch portion 6 may not be arranged on the interior member 1. As shown in FIG. 3, the boundary E dips forward from the surfaces of the first exposed portion 20 and the second exposed portion 30 (the portions that protrude most rearward among the surfaces). Therefore, the operator can recognize the boundary E by touch. Accordingly, the operator can recognize (search for) the positions of the desired input areas A2 to D2 by groping based on the position of the boundary E.

[0084] The adhesion mode between the first buried portion 21 and the second buried portion 31 shown in FIG. 6 is not particularly limited. The first buried portion 21 and the second buried portion 31 may be directly adhered (including fusion). The first buried portion 21 and the second buried portion 31 may be indirectly adhered via an adhesive layer (which may be a single layer or a multi-layer). The same applies to the adhesion form between the wiring portion 41 and the first buried portion 21 and the adhesion form between the wiring portion 41 and the first exposed portion 20.

[0085] The configurations of the first exposed portion 20 and the first buried portion 21 may be the same or different. For example, the first exposed portion 20 may include an epidermal layer 200, an intermediate layer 201, and a design layer 202, and the first buried portion 21 may include only an epidermal layer 210. That is, the first buried portion 21 may not include an intermediate layer 211 and a design layer 212.

[0086] The configuration of the flexible portion 7 is not particularly limited. It may be an integrated body in which the first flexible layer 70 and the second flexible layer 71 are integrated. The configuration of the base portion 8 is not particularly limited. It may be an integrated body in which the first base material 80 and the second base material 81 are integrated.

[0087] The configuration of the sensor portion 4 is not particularly limited. The number of sensors 4A to 4D arranged may be single or plural. For example, when the number of sensors 4A to 4D arranged is single, the intersections of a plurality of strip-shaped front-side electrode layers 400 and a plurality of strip-shaped back-side electrode layers 402 arranged in a grid pattern when viewed from the front side (the laminated portions of the front-side electrode layer 400, the insulating layer 401, and the back-side electrode layer 402 (see FIG. 5)) may be used as the input regions A2 to D2.

[0088] The types of sensors 4A to 4D are not particularly limited. For example, they may be a capacitance-type sensor, a resistive film-type sensor, a strain gauge-type sensor, a piezoelectric effect-type sensor, etc. It is only necessary to be able to detect the physical quantity input when the operator touches the first exposed portion 20. The type of physical quantity is not particularly limited. For example, length, mass, time, current, load, pressure, energy, etc. may be mentioned.

[0089] As the "transducer" of the present disclosure, instead of the sensors 4A to 4D, a tactile switch or an actuator may be arranged. As the actuator, for example, an electrostatic actuator, an electromagnetic actuator, a piezoelectric actuator, etc. may be arranged. The electrostatic actuator may include a front-side electrode layer 400, an insulating layer 401, and a back-side electrode layer 402 (see FIG. 5).

[0090] The wiring portion 41 shown in FIG. 6 does not necessarily have to include the insulating layer 411. It is only necessary to ensure insulation between the front-side wiring layer 410 and the back-side wiring layer 412. The types of the front-side wiring layer 410 and the back-side wiring layer 412 are not particularly limited. For example, they may be a conductive sheet, a conducting wire, etc. The configuration of the end portion of the wiring portion 41 is not particularly limited. For example, it may be a connector, a coupler, a terminal, etc. Also, it may be the wiring portion 41 itself (for example, the end of a conductive sheet or the end of a conducting wire).

[0091] As shown in FIG. 2, the sensor 4A includes the input region A2, the sensor 4B includes the input region B2, the sensor 4C includes the input region C2, and the sensor 4D includes the input region D2, respectively. Also, a first region A3 is arranged on the back side of the input region A2, a first region B3 is arranged on the back side of the input region B2, a first region C3 is arranged on the back side of the input region C2, and a first region D3 is arranged on the back side of the input region D2, respectively. A hardness difference may be set between at least two of these first regions A3 to D3. In this case, any first region (for example, the upper first regions A3, B3) corresponds to the high-hardness region H, and the other first region (for example, the lower first regions C3, D3) corresponds to the low-hardness region L. The method of setting the hardness difference is the same as that in FIGS. 5, 8(A) to 8(C).

[0092] The number of arrangements, positions, sizes, shapes, etc. of the recesses 203A to 203D shown in FIGS. 2, 3, and 5 are not particularly limited. The number of arrangements of the display areas A1 to D1 and the number of arrangements of the recesses 203A to 203D may be the same or different. For example, a single display area A1 to D1 may be formed by a plurality of recesses 203A to 203D. Also, a plurality of display areas A1 to D1 may be formed by a single recess 203A to 203D. The positions of the openings of the recesses 203A to 203D are not particularly limited. The recesses 203A to 203D may open to the front or back surface of the design layer 202. When the recesses 203A to 203D open to the front surface of the design layer 202, the position of the bottom of the recesses 203A to 203D may be within the layer of the design layer 202, on the surface of the front electrode layer 400, within the layer of the front electrode layer 400, etc. When the recesses 203A to 203D open to the back surface of the design layer 202, the position of the bottom of the recesses 203A to 203D may be within the layer of the design layer 202, on the back surface of the intermediate layer 201, within the layer of the intermediate layer 201, etc.

[0093] The display areas A1 to D1 may be arranged at least in the design layer 202 among the intermediate layer 201, the design layer 202, and the front electrode layer 400 according to the number of arrangements, positions, sizes, shapes, etc. of the recesses 203A to 203D. That is, the design layer 202 may have at least a part of the display areas A1 to D1.

[0094] The on and off states of the light sources 90A to 90D are not particularly limited. The interior member 1 may be provided with a trigger sensor for turning on the light sources 90A to 90D. The light sources 90A to 90D may be constantly on. Also, in conjunction with vehicle lights (such as interior lights, headlights, etc.), the light sources 90A to 90D may be turned on and off.

[0095] The design displayed on the first display portion 20 by the display areas A1 to D1 (concave portions 203A to 203D) is not particularly limited. For example, there is a design (a design including one or more selected from patterns, characters, figures, symbols, etc.) arranged as the aforementioned "input position notification member". Also, the color of the design displayed on the first display portion 20 may be single-color or multi-color. The color may be displayed on the first display portion 20 by one or more selected from the skin layer 200, the intermediate layer 201, the design layer 202, and the light sources 90A to 90D.

[0096] The light transmittance of the skin layer 200 and the intermediate layer 201 is not particularly limited. It may be colorless transparent, colored transparent, semi-transparent, etc. The design layer 202 does not necessarily have light-shielding properties. That is, the design layer 202 only needs to have a lower light transmittance than the intermediate layer 201. The colors (hue, chroma, lightness) of the skin layer 200, the intermediate layer 201, the design layer 202, and the light sources 90A to 90D are not particularly limited. Also, the brightness of the light sources 90A to 90D is not particularly limited.

[0097] The types, number of arrangements, and positions of the light sources 90A to 90D are not particularly limited. The light sources 90A to 90D may be an organic EL sheet, an inorganic EL sheet, a phosphorescent sheet, etc. Also, the light source unit 9 may include the light sources 90A to 90D and a light guide plate (for example, an acrylic plate). Also, the light sources 90A to 90D may be arranged adjacent to the first base material 80 in the surface direction of the first base material 80 to cause surface light emission on the surface of the first base material 80.

[0098] The interior products in which the interior member 1 is arranged are not particularly limited. For example, there are door trims, seats, floors, ceilings, instrument panels, glove boxes, steering wheels, center consoles, registers, etc. The installation surface of the interior member 1 in the interior product may be a flat surface or a curved surface. The orientation (front-back direction orientation) when installing the interior member 1 is not particularly limited. The interior member 1 may be arranged in interior products of ships, aircraft, buildings, and houses other than vehicles.

[0099] The layer structure of the interior member 1 is not particularly limited. Among the first skin material 2, the sensor unit 4, the flexible unit 7, and the base 8, another layer may be interposed between two adjacent layers in the front-back direction. The same applies to the structure within each of these layers (for example, the structure of the skin layer 200, the intermediate layer 201, and the design layer 202 within the first exposed portion 20 of the first skin material 2). Also, another layer may be disposed on the front side of the first skin material 2. The same applies to the second skin material 3. In the above embodiment, the skin material is composed of two divided bodies (the first skin material 2 and the second skin material 3), but the number of divided bodies is not particularly limited.

[0100] [Regarding the material] The materials of the skin layers 200, 210, and the second skin material 3 are not particularly limited. For example, synthetic leather, resin, elastomer, non-woven fabric, various fabrics (such as woven fabric, knitted fabric, etc.) can be mentioned. Specifically, as the synthetic leather, resin, and elastomer, acrylic, polyethylene terephthalate, polycarbonate, polyvinyl chloride, silicone, epoxy, polyurethane, styrene-based thermoplastic elastomer, olefin-based thermoplastic elastomer, dynamically crosslinked thermoplastic elastomer, etc. can be mentioned. As the non-woven fabric and various fabrics, polyester, polypropylene, nylon, cotton, etc. can be mentioned. The skin layers 200, 210, and the second skin material 3 may contain a colorant (such as colored polyethylene), a light diffusing agent (such as silicone, acrylic, titanium oxide, etc.), and a light absorbing agent (such as titanium black, carbon black, etc.).

[0101] The materials of the intermediate layers 201, 211 are not particularly limited. For example, resins and elastomers such as acrylic, polyethylene terephthalate, polycarbonate, polyvinyl chloride, silicone, polyester, epoxy, polyurethane, styrene-based thermoplastic elastomer, olefin-based thermoplastic elastomer, dynamically crosslinked thermoplastic elastomer, etc. can be mentioned. The intermediate layers 201, 211 may contain the aforementioned colorant, light diffusing agent, and light absorbing agent.

[0102] The materials of the design layers 202 and 212 are not particularly limited. For example, resins and elastomers such as acrylic, polyethylene terephthalate, polycarbonate, polyvinyl chloride, silicone, polyester, epoxy, polyurethane, styrene-based thermoplastic elastomer, olefin-based thermoplastic elastomer, dynamically crosslinked thermoplastic elastomer, etc. may be mentioned. The design layers 202 and 212 may contain the aforementioned colorants, light diffusing agents, and light absorbing agents.

[0103] The materials of the first flexible layer 70 and the second flexible layer 71 are not particularly limited. For example, elastomers such as styrene-based thermoplastic elastomer, olefin-based thermoplastic elastomer, dynamically crosslinked thermoplastic elastomer, and foams such as polyurethane foam may be mentioned. When the first flexible layer 70 is provided with the through holes 700A to 700D, light transmittance due to the material is not required.

[0104] Regarding the sensors 4A to 4D, the materials of the insulating layers (insulating layers 401 and 411) are not particularly limited. The thermoplastic elastomer for the insulating layer is not particularly limited. It may be appropriately selected from elastomers such as styrene-based, olefin-based, vinyl chloride-based, urethane-based, ester-based, and amide-based. One type or two or more types of thermoplastic elastomers may be used. For example, as the styrene-based thermoplastic elastomer, SBS (styrene-butadiene-styrene block copolymer), SEBS (styrene-ethylene-butylene-styrene block copolymer), SEPS (styrene-ethylene-propylene-styrene block copolymer), etc. may be mentioned. As the olefin-based elastomer, in addition to EEA (ethylene-ethyl acrylate), EMA (ethylene-methyl acrylate), EMMA (ethylene-methyl methacrylate copolymer), etc., copolymers of ethylene and α-olefin (ethylene-octene copolymer), etc. may be mentioned.

[0105] For the insulating layer, rubbers, resins, and foams other than thermoplastic elastomers may be used. For example, rubbers such as ethylene propylene rubber (EPM (ethylene propylene copolymer), EPDM (ethylene propylene diene terpolymer)), resins such as acrylic, polyethylene terephthalate, polycarbonate, polyvinyl chloride, silicone, polyester, epoxy, and foams such as polyurethane foam can be mentioned.

[0106] The material of the conductive layer (front conductive layer (front electrode layer 400, front wiring layer 410), back conductive layer (back electrode layer 402, back wiring layer 412)) is not particularly limited. The conductive layer preferably has conductivity and flexibility. Examples of the material of the conductive layer include conductive rubber and conductive cloth.

[0107] The conductive rubber has an elastomer and a conductive material. As the elastomer, one or more selected from crosslinked rubbers such as acrylic rubber, silicone rubber, urethane rubber, urea rubber, fluororubber, nitrile rubber, hydrogenated nitrile rubber, and thermoplastic elastomers may be used. As the conductive material, metal particles composed of silver, gold, copper, nickel, rhodium, palladium, chromium, titanium, platinum, iron, and their alloys, metal oxide particles composed of zinc oxide, titanium oxide, etc., metal carbide particles composed of titanium carbonate, etc., metal nanowires composed of silver, gold, copper, platinum, nickel, etc., and conductive carbon materials such as carbon black, carbon nanotubes, graphite, thin-layer graphite, graphene can be appropriately selected. The conductive rubber may contain a crosslinking agent, a crosslinking accelerator, a dispersant, a reinforcing material, a plasticizer, an antioxidant, a colorant, etc.

[0108] As the conductive cloth, a woven fabric or non-woven fabric of conductive fibers may be used. Examples of the conductive fibers include polyester fibers such as PET (polyethylene terephthalate) plated with highly conductive copper, nickel, etc.

[0109] The materials of the first substrate 80 and the second substrate 81 are not particularly limited. For example, resins and elastomers such as acrylic, polyethylene terephthalate, polycarbonate, polyvinyl chloride, silicone, polyester, epoxy, polyurethane, styrene-based thermoplastic elastomer, olefin-based thermoplastic elastomer, and dynamically crosslinked thermoplastic elastomer can be mentioned. In order to ensure the shape retention of the interior member 1, the first substrate 80 and the second substrate 81 may be harder than other layers (the first skin material 2, the second skin material 3, the sensor unit 4, the first flexible layer 70, the second flexible layer 71).

[0110] The members (for example, the base 8, the flexible part 7, the sensor unit 4, etc.) intervening between the light sources 90A to 90D and the display areas A1 to D1 may have light transmissivity and light diffusibility. The method for imparting light diffusibility to these members is not particularly limited. For example, a light diffusing agent (such as silicone, acrylic, titanium oxide, etc.) having a refractive index different from that of the base material may be dispersed in a transparent base material. Further, these members may have light introduction holes.

[0111] The lamination method of the skin layer 200, the intermediate layer 201, and the design layer 202 in the first skin material 2 shown in FIG. 4 is not particularly limited. Screen printing, gravure printing, inkjet printing, flexographic printing, etc. may be used. Also, each layer may be laminated by adhesion, vapor deposition, or the like. The same applies to the lamination method of the skin layer 210, the intermediate layer 211, and the design layer 212. The method for forming the recesses 203A to 203D in the first skin material 2 is not particularly limited. Laser processing, photoetching, etc. may be used.

[0112] The fixing method of the sensors 4A to 4D shown in FIG. 3 to the first skin material 2 and the first soft layer 70 is not particularly limited. For example, when the installation surface of the interior member 1 in the interior product (instrument panel 92 shown in FIG. 1) is a convex surface that bulges to the front side, the other layers (first soft layer 70, sensors 4A to 4D, first skin material 2) on the outer side of the radius of curvature press against the base 8 on the inner side of the radius of curvature of the curvature. Using the pressing force, the sensors 4A to 4D can be fixed to the first skin material 2 and the first soft layer 70. On the contrary, when the installation surface of the interior member 1 in the interior product is a concave surface that bulges to the back side, the above-mentioned pressing force does not act. In this case, the sensors 4A to 4D can be fixed to the first skin material 2 and the first soft layer 70 by using an adhesive or a double-sided tape.
