FIG. 1 is an explanatory view showing an example of a vehicle seat covered with a skin material of the present invention, and FIG. 2 is a portion of the skin material of the present invention. FIG. 3 is an enlarged view of a portion where a sewing thread pattern, a seam hole pattern, and a joint portion pattern are formed, FIG. 4 is a cross-sectional view showing a joint portion pattern provided with an undercut portion, and FIG. 5 is an undercut portion. Is a sectional view showing a sewing thread pattern provided on one side, and FIG. 6 is a sectional view showing a sewing thread pattern provided with undercut portions on both sides.
[0020]
The skin material 10 of the present embodiment is mainly used for a seat for an outdoor vehicle, and is particularly used for a motorcycle seat S as shown in FIG. In addition, the present invention can be used not only for motorcycle seats, but also for vehicle seats related to three-wheeled buggy vehicles, hakama seat-type vehicles, construction machine seats, agricultural machine seats, snowmobiles, personal watercrafts, and the like.
[0021]
The skin material 10 includes a synthetic resin layer 11 and a fiber base layer 12. The synthetic resin layer 11 is formed from a polyvinyl chloride resin, a polyolefin resin, an acrylic resin, or the like. If necessary, various additives such as a plasticizer, a stabilizer, an antioxidant, an ultraviolet absorber, a lubricant, an antistatic agent, a pigment, and an inorganic filler may be added to the synthetic resin layer.
[0022]
The fiber base layer 12 is made of a woven fabric such as a woven fabric or a knitted fabric, or a nonwoven fabric such as a natural fiber or a synthetic fiber. In particular, a knitted fabric or the like has elasticity, and is suitable because it follows the synthetic resin layer 11 when a sewing thread pattern or a grain pattern is provided on the synthetic resin layer 11.
[0023]
Note that a surface treatment layer such as a urethane paint layer or a silicone urethane paint layer may be provided on the surface of the synthetic resin layer 11. Further, an antistatic agent, an antioxidant, a pigment and the like may be added to these paint layers as needed.
[0024]
The skin material 10 of the present example has a predetermined shape having the same appearance as that of a joint formed by actually joining a plurality of skin materials by sewing or welding welding on the surface thereof, and is formed by transfer. Although it is a skin material, it has the same external shape as the three-dimensional appearance obtained by actually joining a plurality of skin materials by sewing or welding welding, and is formed three-dimensionally.
[0025]
FIG. 2 is a partially enlarged view of the skin material 10 used for the motorcycle seat S. FIG. 2 illustrates a part of the part 13 covering the seat surface, a part of the part 14 covering the side surface, and a part of the part 15 covering the rear side surface.
[0026]
On the surface of the skin material 10, a sewing thread, a seam hole, and an uneven shape of a superimposition of the skin material at a joint portion in order to obtain an appearance in which a plurality of skin materials are joined by sewing, while being a single skin material. And the state where the sewing thread bites into the skin material is transferred.
[0027]
That is, on the surface of the skin material 10, a sewing thread pattern 21, a seam hole pattern 22, a joint pattern 23, and a pattern 24 indicating a state in which the sewing thread has cut into the skin material are formed by transfer.
[0028]
The transfer of the above-described shapes to the skin material 10 is performed by a conventionally known method such as welding, embossing, vacuum forming or pressure forming, injection molding, blow molding, and the like, and the production method is not particularly limited. As shown in FIG. 11, when the transfer is performed by vacuum forming or pressure forming using a mold 27 made of a porous material having fine holes, the skin material 10 is formed into a three-dimensional shape, and the sewing thread pattern 21 is formed. Since various patterns such as the joint pattern 23 and the joint pattern 23 can be simultaneously transferred, the sewing thread pattern 21 and the joint pattern 23 are not deformed later. For this reason, even the details of multiple pieces of skin material actually joined by sewing on the surface of the seat as a product can be faithfully reproduced in exactly the same shape, making it possible to give a more authentic appearance It becomes. Further, since it is not necessary to align the patterns as in the case where the skin material 10 is formed later, it is possible to improve work efficiency.
[0029]
As the mold 27 made of the porous material, it is preferable to use a mold made of a porous material having fine pores having a pore diameter of 3 μm to 25 μm. If it is smaller than 3 μm, the vacuum efficiency is poor, and if it is larger than 25 μm, precise transfer cannot be performed. When the hole diameter is within the range of the above-mentioned hole diameter, preferably, 10 μm to 20 μm, precise transfer can be performed without lowering the vacuum efficiency, and the best balance between production efficiency and transfer reproducibility is obtained. .
[0030]
FIG. 3 is an enlarged view of a portion where the sewing thread pattern 21, the seam hole pattern 22, and the joint pattern 23 are formed. The joint pattern 23 is formed so as to protrude from the general surface 16 of the skin material 10. In the example of FIG. 3, the synthetic resin layer 11 and the fiber base material layer 12 are curved upward by molding, whereby the joint pattern 23 is formed in a raised state.
[0031]
In this manner, by forming the joint pattern 23 into the uneven shape, a state in which two skin materials are overlapped on the skin material 10 is expressed.
[0032]
A sewing thread pattern 21 is formed on the joint pattern 23. The sewing thread pattern 21 represents a state where the two skin materials are sewn together at the joint.
[0033]
The sewing thread pattern 21 is a pattern representing a thread of a single stitch. On the surface of the sewing thread pattern 21, a pattern in which fibers are twisted is formed, and the appearance is like a real thread.
[0034]
A stitch hole pattern 22 is formed between the sewing thread patterns 21. The seam hole pattern 22 is formed so as to have an appearance in which the end of the sewing thread enters the seam hole.
[0035]
In addition, as shown in FIG. 4, a configuration in which an undercut portion 25 is provided in a portion of the joint pattern 23 may be adopted. Since the molding material of the skin material 10 is soft and elastic, the undercut portion 25 can be formed by forcible blanking.
[0036]
By providing the undercut portion 25, the joint pattern 23 has an appearance protruding toward the general surface 16 of the skin material 10 located on the lower side, and the joint pattern 23 and the skin material 10 located on the lower side are formed. It looks like a separate body, and it is possible to express the state in which two skin materials overlap one another more realistically.
[0037]
Further, as shown in FIG. 5, an undercut portion 25 may be provided in the portion of the sewing thread pattern 21. By providing the undercut portion 25 in the portion of the sewing thread pattern 21, the sewing thread pattern 21 is made to stand out, and the sewing thread pattern 21 and the joint pattern 23 have an appearance that is separate from each other, and the sewing is actually performed with the thread. The state can be expressed more realistically.
[0038]
The undercut portion 25 may be provided on one side of the sewing thread pattern as shown in FIG. 5, or may be provided on both sides of the sewing thread pattern as shown in FIG. Further, the undercut portions 25 may not be provided on all the sewing thread patterns 21 but may be provided every other or at random.
[0039]
FIG. 7 is an explanatory diagram showing a joint pattern 23 of another embodiment. In the example shown in FIG. 7, in order to make the joint pattern 23 protrude from the general surface 16 of the skin material 10, the synthetic resin layer 11 in the part of the joint pattern 23 is made thicker than the other parts. 23 are formed so as to swell.
[0040]
As described above, even when the synthetic resin layer 11 in the portion of the joint pattern 23 is thickened, as shown in FIG. This is preferable because it is possible to more realistically represent a state in which the skin materials overlap.
[0041]
As shown in FIG. 9, a pattern 24 representing a state in which the sewing thread has cut into the skin material is formed in the joint pattern 23. When sewing two skin materials, usually, first, the front surfaces of the skin materials are joined together and the ends are sewn together, then the upper skin material is turned over and stitched from the surface side. The pattern 24 is to be sewn, and the pattern 24 is a reproduction of a state in which the sewing thread sewn first is exposed to the outside.
[0042]
The stitches applied from the front side are formed as sewing thread patterns 21 on the upper surface of the skin material 10.
[0043]
As described above, in the skin material 10 of the present example, not only the sewing thread, the seam hole, and the joint portion, but also the sewing thread and the joint portion with the undercut portion and even the state in which the sewing bites into the skin material are included. It is transcribed and the shape related to the sewing is faithfully restored. In this way, an appearance similar to the appearance obtained by joining a plurality of skin materials by sewing is reproduced on one skin material.
[0044]
Further, in the skin material 10 of this example, different grain patterns are formed with the joint pattern 23 as a boundary. In this example, as shown in FIGS. 1 and 2, the portion 13 covering the seat surface, the portion 14 covering the side surface, and the portion 15 covering the rear side surface have different patterns. .
[0045]
Further, a pattern portion 26 that is a decorative sewing portion is provided in the portion 13 that further covers the seating surface, and the appearance of the surface material having different grain patterns is joined with the pattern portion 26 as a boundary. I have. The portions where the skin materials having different patterns are adjacent to each other are provided with a sewing thread pattern 21, a seam hole pattern 22, a joint portion pattern 23, and a pattern 24 in which the sewing cuts into the skin material, respectively. Has the appearance actually joined by sewing.
[0046]
The patterns such as the sewing thread pattern 21, the seam hole pattern 22, and the joint pattern 23 are not limited to the above-described configuration, and can be freely changed in accordance with the design.
[0047]
For example, a joint pattern 23 provided with an undercut portion 25 is formed on the skin material 10 shown in FIG. 10, and a sewing thread pattern provided with an undercut portion 25 is provided adjacent to the joint pattern 23. 21 are formed. A stitch hole pattern 22 is formed between the sewing thread patterns 21. Also, the grain pattern is not limited to the above-described configuration, but may be another pattern, have a different luster, or have a portion having no grain pattern.
[0048]
Further, in the above-described embodiment, the structure in which the joint pattern 23 protrudes from the general surface 16 is shown, but the joint pattern 23 and the general surface 16 may be flat. In this case, for example, the portion of the general surface 16 adjacent to the joint pattern 23 is formed so as to be substantially flush with the joint pattern 23. Since the joint pattern 23 and the general surface 16 have a flat shape in this manner, a state in which the joint projects toward the back surface side of the skin material and no irregularities appear on the front surface side is expressed. You.
[0049]
Furthermore, in the above-described embodiment, the skin material 10 having the appearance in which a plurality of skin materials are joined by sewing is described. However, the appearance is not limited to sewing, and the appearance in which a plurality of skin materials are joined by welder welding may be used. Is also good.
[0050]
In this case, the concavo-convex shape of the superimposed skin material of the joint is transferred to the skin material to form a joint pattern. Even when the joint pattern is formed by welding welding, an undercut portion may be provided as necessary, so that the joint pattern and the skin material located on the lower side look like separate bodies.
[0051]
【The invention's effect】
As described above, according to the present invention, a predetermined shape having the same appearance as a joint or a sewing thread actually joined by sewing or welding welding is formed on a single skin material by transfer. This creates the same appearance as the three-dimensional appearance of multiple skins actually joined by sewing or welding welding, so even when seats are manufactured by covering the cushioning material, It is possible to obtain a high-quality vehicle skin material and a vehicle seat having the same appearance as a seat covered with a skin assembly actually manufactured by sewing or the like without causing deformation or the like. . In addition, since it is a single skin material, it is suitable because rainwater does not enter even when it is used for an outdoor vehicle seat.
