(Embodiment 1)
FIG. 1 shows a substantially left half of the instrument panel 1 for an automobile on the passenger seat side. As shown in FIG. 1, a panel mounting portion 3 extending in a band shape in the vehicle width direction is formed on the passenger seat side of the instrument panel 1. A decorative panel 5 as a vehicle interior product according to the first embodiment of the present invention is mounted on the panel mounting portion 3 to give a design accent to the interior of the automobile.

As shown in FIGS. 2 and 3, the decorative panel 5 is a horizontally long plate-shaped panel corresponding to the shape of the panel mounting portion 3. In the decorative panel 5, the decorative skin 7 forming the front surface layer of the decorative panel 5 and the resin base material panel 9 as the base material forming the back surface layer of the decorative panel 5 are arranged substantially in parallel. A cushioning material 11 made of urethane foam or the like is provided between the decorative skin 7 and the base panel 9 in a state of being integrated with the base panel 9 by adhesion or adhesion.

The decorative skin 7 is made by sewing a plurality of skin materials made of, for example, genuine leather, synthetic leather, and fabric. When the skin material is synthetic leather, for example, a resin material such as PVC (polyvinyl chloride), TPO (thermoplastic olefin), TPU (thermoplastic urethane) is slush-molded.

The base material panel 9 is an integral molded product that is injection-molded with a resin material such as PP (polypropylene) or ABS (acrylonitrile-butadiene-styrene).

The urethane foam constituting the cushion material 11 is formed into a sheet shape and cut out corresponding to the surface side shape of the base material panel 9.

The base panel 9 is formed in an elongated dish shape in which the intermediate portion is recessed toward the rear of the vehicle. Specifically, the base material panel 9 has a horizontally long flat plate-shaped main body portion 13 extending in the vehicle width direction constituting the base portion of the design surface of the decorative panel 5, and the peripheral portion of the main body portion 13 toward the front of the vehicle. The tapered portion 15 that is inclined and protrudes as described above is integrally formed. Further, on the surface of the main body 13 located on the rear side of the vehicle, a base material recess 19 having the same depth as the thickness of the first skin material 17, which will be described later, is formed in the vertical intermediate portion in the vertical direction (vehicle width direction). The first skin material 17 is fitted into the base material recess 19 so as to be substantially flush with each other. On the other hand, on the back surface of the main body 13 (the surface located on the front side of the vehicle), a plurality of clip mounting pedestals 21 projecting toward the front of the vehicle are integrally formed, and a clip 23 is provided at the tip thereof. The decorative panel 5 is fixed to the instrument panel 1 by inserting the clip 23 into a panel mounting hole (not shown) formed in the panel mounting portion 3 of the instrument panel 1.

The decorative skin 7 is an elongated sheet having an area larger than the surfaces of the main body portion 13 and the tapered portion 15 of the base material panel 9, and extends in parallel with the main body portion 13 and the tapered portion 15 of the base material panel 9. There is.

The decorative skin 7 includes a first skin material 17, a second skin material 25 and a third skin material 27 which are arranged so as to be overlapped on the surface of the first skin material 17. The first skin material 17 constituting the decorative skin 7 is formed in a rectangular shape corresponding to the base material recess 19 of the base material panel 9, and the thickness is preferably 0.8 mm or more and 1.2 mm or less. .. The surface brightness is a color system of PCCS (Practical Color Co-ordinate System), which is colored 7.5 or more and 9.5 or less, for example, a silver color. The brightness of the surface of the first skin material 17 may be less than 7.5 in the color system of PCCS, but in that case, the shadow 39 (detailed later) reflected on the surface of the first skin material 17 is formed. Since it becomes difficult to see visually, it is preferable to set the brightness to 7.5 or more.

The second skin material 25 and the third skin material 27 are formed in a rectangular shape having the same length in the vehicle width direction as the first skin material 17, and the thickness is 0.8 mm or more and 1.2 mm or less. preferable.

As shown in FIGS. 4 and 10, in the decorative skin 7, the second skin material 25 and the third skin material 27 are arranged on the surface of the first skin material 17, and both skin materials 25, Each end of 27 is arranged so as to extend parallel to the length direction (vehicle width direction) of the first skin material 17 and face each other with a certain distance from each other, and the second skin material 25 and the third skin material 27 and the third. Folded portions 29, 29 are formed at the opposing ends of the skin material 27, with the edge portions of the skin materials 25, 27 folded back. A groove-shaped recess 31 is formed in a portion surrounded by the facing ends of the second skin material 25 and the third skin material 27 and the surface of the first skin material 17. Further, each of the folded-back portions 29, 29 is sewn to the first skin material 17 by the ground stitch thread 33 at the end on the recess 31 side, and the second skin material 25 and the third skin material 27 face each other. Each of the end portions is sewn to the first skin material 17 in the vehicle width direction with the line stitch thread 35 together with the folded-back portion 29, whereby the surfaces of the second skin material 25 and the third skin material 27 are sewn together. Line stitches are formed. Further, between the ends of the second skin material 25 and the third skin material 27, they intersect in an X shape in a plan view so as to reach the other surface from one surface through the opening position of the recess 31. The cross-stitch thread 37 is bridged over, and a space S is formed in a portion surrounded between the cross-stitch thread 37 and the surface of the first skin material 17 in the recess 31. Further, since the surface of the first skin material 17 is glossy, the shadow 39 of the cross-stitch thread 37 is reflected on the surface. In other words, the cross-stitch thread 37 is visually projected on the same surface.

The decorative skin 7 is integrated with the base panel 9 in a state of covering the surface thereof. Specifically, as shown in FIG. 3, the first skin material 17 of the decorative skin 7 is embedded in the base material recess 19, and the surface of the first skin material 17 and the surface of the base panel 9 are flush with each other. It has become. The cushion material 11 is arranged on the surface of the base material panel 9 in a portion excluding the base material recess 19. Since the thickness of the cushion material 11 is the same as that of the second skin material 25 and the third skin material 27, the edge portions of the folded portions 29 and 29 of both skin materials 25 and 27 are the cushion materials 11. It is abutted against the end portion, and in that state, the mating surface of each folded portion 29 and the surface of each cushion material 11 and 11 are flush with each other. The second skin material 25 and the third skin material 27 cover the surface of the base material panel 9, and the end portion on the side opposite to each folded portion 29 is bent to the back side of the tapered portion 15 of the base material panel 9, and the back surface thereof. In, for example, it is fixed by adhesion.

The procedure for manufacturing the decorative skin 7 having the above configuration will be described below with reference to FIGS. 5 to 10.

First, as shown in FIG. 5, the first skin material 17 and the second skin material 25 are overlapped so that one edge portion of the first skin material 17 and the edge portion of the second skin material 25 coincide with each other. In that state, ground stitching is performed with a sewing machine or the like in the direction along the edge portion, and the first skin material 17 and the second skin material 25 are sewn with the ground sewing thread 33. After that, as shown in FIG. 6, the second skin material 25 is folded back with reference to the sewn portion to form the folded portion 29 on the second skin material 25.

Next, as shown in FIG. 7, the other edge portion of the first skin material 17 and the edge portion of the third skin material 27 are aligned and overlapped with each other, as in the case of the second skin material 25. The first skin material 17 and the third skin material 27 are sewn together by sewing with a sewing machine or the like. After that, as shown in FIG. 8, the folded-back portion 29 is formed on the third skin material 27 by folding the third skin material 27 with reference to the sewn portion.

At this time, the ground stitch 33 of the second skin material 25 and the third skin material 27 is temporarily fixed to the first skin material 17, and the folded portion 29 can be easily formed by folding back the portion as a reference. ..

Next, as shown in FIG. 9, each end of the line stitch thread 35 appears on the surfaces of the second skin material 25 and the third skin material 27 from the top of the folded-back portion 29 to the first skin material 17. A line stitch is formed by suturing with a sewing machine or the like.

After that, as shown in FIG. 10, two cross-stitch threads 37, 37 are engaged with the line stitch threads 35, 35 in a staggered manner between the ends of the second skin material 25 and the third skin material 27. Cross-stitch is formed so as to intersect in an X shape at the portion between the ends of both skin materials 25 and 27. In this way, the decorative skin 7 is formed.

Then, the decorative skin 7 is arranged on the surface of the base material panel 9 to which the cushion material 11 is attached, and the first skin material 17 of the decorative skin 7 is fitted into the base material recess 19 to form the peripheral edge of the decorative skin 7. The decorative panel 5 of the present embodiment is formed by integrating the decorative skin 7 and the base panel 9 by bending the base panel 9 to the back side of the tapered portion 15 and adhering it to the back surface. ..

Therefore, according to the present embodiment, in the decorative skin 7, the ends of the second skin material 25 and the third skin material 27 are overlapped on the surface of the first skin material 17 so as to face each other at intervals. A space S is formed between the cross-stitch thread 37 spanned between the ends of both skin materials 25 and 27 and the first skin material 17, and since they are not in contact with each other, the decorative skin 7 has a three-dimensional effect. And a feeling of depth is generated, and thus the design of the decorative panel 5 is improved.

Further, the second skin material 25 and the third skin material 27 are provided with folded portions 29 and 29, and the space between them is provided so that the recess 31 serving as the space S is provided as the second skin. It is possible to secure a depth deeper than the thickness of the material 25 and the third skin material 27 itself, and a sufficient space S is easily formed between the cross-stitch thread 37 and the first skin material 17 without using a special member to design the design. The sex can be improved.

Further, since the cross-stitch thread 37 is provided on the surface of each end of the second skin material 25 and the third skin material 27, the height position of the cross-stitch thread 37 from the surface of the first skin material 17 becomes higher. The entire recess 31 can be used as a space S between the cross-stitch thread 37 and the first skin material 17, and the stitch thread is simply provided on the surfaces of the second skin material 25 and the third skin material 27. With the configuration, the space S between the cross-stitch thread 37 and the first skin material 17 can be further widened.

Further, if the surface brightness of the first skin material 17 is 7.5 or more and 9.5 or less in the PCCS color system, the shadow 39 of the cross stitch thread 37 projected on the first skin material 17 becomes easy to see. If the surface of the first skin material 17 is glossy, the shadow 39 stands out from other parts, making it easier to see. On the surface of the first skin material 17 of the present embodiment, the shadow 39 can be more easily seen due to the synergistic effect of both high brightness and gloss, and the three-dimensional effect and depth of the decorative panel 5 can be enhanced. ..

By the way, if the thickness of the first skin material 17 is too thin, the first skin material 17 may lose its elasticity and may be pulled by the second skin material 25 and the third skin material 27 and float from the base panel 9. .. As a result, the space S formed between the first skin material 17 and the stitch thread is narrowed, so that the three-dimensional effect and the depth feeling are lost, and the design of the decorative panel 5 may be deteriorated. On the contrary, if the thickness is too thick, the depth of the base material recess 19 of the base material panel 9 must be deepened according to the thickness of the first skin material 17, so that the material of the base material panel 9 increases. The cost goes up. If the thickness of the first skin material 17 is 0.8 mm or more and 1.2 mm or less as in the present embodiment, these problems do not occur.

Further, if the thickness of the second skin material 25 and the third skin material 27 is too thin, the depth of the recess 31 cannot be sufficiently secured, so that the space S between the cross-stitch thread 37 and the surface of the first skin material 17 is created. It becomes narrower and loses its three-dimensional effect and depth. On the contrary, if the thickness is too thick, it becomes difficult to fold the second skin material 25 and the third skin material 27 when forming the folded portion 29, and the folded portion 29 cannot be formed to the target size. This problem is particularly remarkable when the second skin material 25 and the third skin material 27 are made of genuine leather. If the thickness of the second skin material 25 and the third skin material 27 is 0.8 mm or more and 1.2 mm or less as in the present embodiment, these problems can be solved.

(Embodiment 2)
FIG. 11 shows the second embodiment of the present invention, in which the skin material forming the decorative skin 7 is changed. In the following description of each embodiment, the same parts as those in FIGS. 1 to 10 are designated by the same reference numerals, detailed description thereof will be omitted, and points different from those of the first embodiment will be described.

In the present embodiment, the thickness of the second skin material 25 and the third skin material 27 is set to, for example, 2.0 mm, which is set to be thicker than that of the first skin material 17. The second skin material 25 and the third skin material 27 of the present embodiment are not formed with the folded-back portion 29, and the respective end portions are treated so as to be rounded in an arc shape in cross section.

In the step of manufacturing the decorative skin 7 of the present embodiment, ground stitching is not performed, and the second skin material 25 and the third skin material 27 are superposed on the first skin material 17 and are laminated with the line stitch thread 35. Sutured in the width direction. Other configurations are the same as those in the first embodiment.

Therefore, according to the present embodiment, since the second skin material 25 and the third skin material 27 are thickly formed, it is possible to secure a sufficient depth of the recess 31 without forming the folded-back portion 29. Therefore, similarly to the first embodiment, the space S between the cross-stitch thread 37 and the first skin material 17 can be widened.

(Embodiment 3)
FIG. 12 shows the third embodiment, in which the height position of the cross-stitch thread 37 is changed. The cross-stitch thread 37 of the present embodiment does not pass through the surfaces of the second skin material 25 and the third skin material 27 as in the first and second embodiments, but passes through the end faces from the mating surfaces of the folded portions 29. An X-shaped cross-stitch is formed at the relevant portion of the facing skin material, for example, by baseball sewing. Other configurations are the same as in the first embodiment.

Therefore, according to the present embodiment, it is possible to secure the dimensions corresponding to the thicknesses of the second skin material 25 and the third skin material 27 as the height of the space S between the cross-stitch thread 37 and the first skin material 17. it can.

(Embodiment 4)
FIG. 13 shows the fourth embodiment. In the present embodiment, the folded-back portion 29 is not formed as in the first embodiment, and instead, the spacers 41 and 41 are formed between the second skin material 25 and the third skin material 27 and the first skin material 17. Is intervened. The spacer 41 may be genuine leather, synthetic leather or fabric used as a skin material, and the configuration of the spacer 41 is not particularly limited as long as the sewing needle for suturing the line stitch thread 35 can pass through. Other configurations are the same as in the first embodiment.

Therefore, according to the present embodiment, by providing the spacer 41 between the second skin material 25 and the third skin material 27 and the first skin material 17, the size of the spacer 41 can be changed by simply changing the second size. Regardless of the thickness of the skin material 25 and the third skin material 27, the space S between the cross-stitch thread 37 and the first skin material 17 can be set to an arbitrary height.

(Other embodiments)
In the above embodiment, the cross-stitch thread 37 is laid between the ends of the second skin material 25 and the third skin material 27, but the stitch thread may be laid so as not to cross.

In each of the above embodiments, the decorative panel 5 is mentioned as an interior product for a vehicle, but the present invention is not limited thereto. For example, it can be applied to vehicle interiors provided with a skin, such as a glove box lid (lid) for an instrument panel, a door trim, and a box lid for a rear console.

In each of the above embodiments, the second skin material 25 and the third skin material 27 are separate skin materials, but the present invention is not limited thereto. For example, one end of one skin material may be used as the second skin material 25, and the other end may be used as the third skin material 27. In that case, the decorative skin 7 is formed in a tubular shape, for example.

In each of the above embodiments, the surface color of the first skin material 17 is silver, but the present invention is not limited to this. For example, a high-brightness color such as white, yellow, or ivory may be used, or the high-brightness color may be given gloss. Further, as the surface layer of the first skin material, a metal foil, a metal-deposited resin sheet, or the like may be used.

In each of the above embodiments, when the cushioning material 11 is provided on the decorative panel 5, after the cushioning material 11 is attached to the base material panel 9, the surface of the base material panel 9 to which the cushioning material 11 is attached is subjected to the decorative skin 7. However, the present invention is not limited to this. For example, the decorative skin 7 and the base panel 9 may be set in a molding die, a foamed resin raw material may be injected between them, and the foamed resin raw material may be foamed and cured to provide a cushioning material 11. .. Further, the surface of the base material panel 9 may be directly covered with the decorative skin 7 without providing the cushion material 11.
