By the way, in the known technique, a dense portion is provided on the edge of the design portion, and in this dense portion, needle holes (hole portions of the present invention) are arranged on the base material so as to form a perforation. For this reason, in leather products by a known technique, there is a possibility that the base material may be cut or torn along a dense portion, and it is necessary to appropriately maintain the strength of the base material. For example, it is conceivable to reduce the thread density on the edge side forming the contour of the design portion to increase the space between adjacent holes, but this tends to deteriorate the appearance because the base material can be seen through the design portion. It is also conceivable to increase the strength of the design portion by thickening the embroidery thread, but at the same time, the hole portion becomes large and a sufficient effect cannot be obtained, and the flexibility of the design portion may be extremely deteriorated. The present invention was invented in view of the above points, and the problem to be solved by the present invention is to provide the embroidered design portion on the base material with good finish while maintaining the strength of the base material as much as possible. It is to keep.

As a means for solving the above problems, the leather product of the first invention includes a leather base material and an embroidered design portion provided on the base material. In the design part, the end of the stitch of the embroidery thread forming the design part is passed through the hole part of the base material to the back side of the base material, and the hole part is densely arranged at least a part of the edge of the design part. There is a densely packed area. In this type of configuration, it is desirable to provide the embroidered design portion on the base material with good finish (for example, good appearance and flexibility) while maintaining the strength of the base material as much as possible. Therefore, on the base material of the present invention, reinforcing portions made of embroidery composed of tatami stitches are arranged overlapping in a dense portion, and the stitches of the embroidery thread forming the reinforcing portion and the sewing of the embroidery thread forming the design portion are sewn. The eyes are arranged in a cross shape. In the present invention, the base material portion on which the densely packed portion is formed is reinforced by overlapping the stitches of the design portion and the stitches of the reinforcing portion in a crossing manner. Therefore, in the present invention, it is possible to maintain the strength of the base material portion in which the dense portion is formed as much as possible without particularly changing the configuration of the design portion (arrangement position of the hole portion, thickness of the embroidery thread, etc.). Will be.

Further , in the leather product of the first invention, even in the reinforcing portion, the end of the stitch of the embroidery thread forming the reinforcing portion is passed through the hole portion of the base material to the back side of the base material, and a dense portion is provided. In the extending direction of the edge of the design portion, the distance between the adjacent holes of the reinforcing portion is made larger than the distance between the adjacent holes of the dense portion. In the present invention, the strength of the base material portion on which the dense portion is formed can be more reliably maintained by increasing the yarn density by relatively increasing the distance (pitch) between the holes of the reinforcing portion. ..

The leather product of the second invention is different from the first reinforcing portion provided in a part of the edge of the design portion provided with the dense portion in the reinforcing portion in the leather product of the first invention. It has a second reinforcing part provided in another part of the edge of the design part, and the first reinforcing part and the second reinforcing part are overlapped on the adjacent end side and are adjacent to both reinforcing parts. A plurality of holes are arranged at the mating ends. Therefore, in the present invention, the end of either the first reinforcing portion or the second reinforcing portion does not overlap with the end of either the first reinforcing portion or the second reinforcing portion different from the one. It is arranged in the other reinforcing part so as to be. In the present invention, the design portion can be more appropriately reinforced by the reinforcing portion provided with the pair of reinforcing portions. Considering that a plurality of holes are arranged at the ends of each reinforcing portion, the strength of the base material can be more reliably maintained by arranging the adjacent ends of both reinforcing portions in a staggered manner. It will be possible.

The leather product of the third invention is the leather product of the first invention or the second invention , in which the design portion is surrounded by a reinforcing portion. In the present invention, the design portion can be more reliably reinforced by enclosing the design portion with the reinforcing portion.

The leather product of the fourth invention is any of the leather products of the first invention to the third invention, and the design portion is composed of at least one of tatami stitch and satin stitch. In the present invention, the design section is configured by selecting either tatami stitch or satin stitch in consideration of the appearance required for the design section, thereby contributing to the improvement of the appearance of the design section.

[Formation of seat back]
By covering the seat pad 6P on the seat frame 6F with the seat cover 6S with reference to FIG. 1, the design surface of the seat is formed by the seat cover 6S. In this state, as shown in FIG. 2, a design portion 10 made of embroidery is arranged at the lower left of the main skin piece SP1, and the design portion 10 improves the design of the seat back 6. Then, as shown in FIG. 3, a dense portion 18 in which the first hole portion H1 is densely formed is formed on the right edge 11 and the left edge 12 of the design portion 10. In this type of configuration, it should be avoided as much as possible that the main skin piece SP1 of the seat cover 6S is cut or torn due to the dense portion 18. Further, since the design portion 10 is arranged on the seating surface side of the seat cover 6S, which is relatively easily visible, the design portion 10 should be formed with good finish so as to have excellent appearance and flexibility.

Therefore, in the main skin piece SP1 of the present embodiment, with reference to FIG. 2, the reinforcing portion 20 made of embroidery made of tatami stitching is overlapped with the dense portion 18. As shown in FIG. 4, the stitches of the reinforcing embroidery thread Y2 forming the reinforcing portion 20 and the stitches of the design embroidery thread Y1 forming the design portion 10 are arranged in an intersecting manner. That is, in this embodiment, for example, the right side reinforcing portion 21 formed of tatami stitching is overlapped on the right edge 11 (dense portion 18) of the design portion 10. Then, on the main skin piece SP1 on which the dense portion 18 is formed, the stitches of the reinforcing embroidery thread Y2 forming the right side reinforcing portion 21 and the design embroidery thread Y1 forming the design portion 10 are overlapped in a cross shape (orthogonal shape in this embodiment). And are arranged. The distance L2 between the adjacent second hole portions H2 of the right side reinforcing portion 21 in the vertical direction is larger than the distance L1 between the adjacent first hole portions H1 of the dense portion 18. By increasing the thread density by relatively increasing the distance L2 between the second hole portions H2 of the right side reinforcing portion 21 in this way, it is possible to avoid damage to the main skin piece SP1 at the densely packed portion 18 as much as possible. Further, the main skin piece SP1 on which the dense portion 18 is formed is in a restrained state in which the embroidery threads Y1 and Y2 are tightened from different directions, and a force (tensile force) that damages the dense portion 18 is applied. Even if it is possible, it is possible to resist this force. Similarly, the left edge 12 (dense portion 18) of the design portion 10 in FIG. 2 is also reinforced by overlapping the left side reinforcing portions 22 configured by tatami stitching.

Thus, in this embodiment, the reinforcing portion 20 shown in FIG. 2 makes it possible to maintain the strength of the main skin piece SP1 on which the dense portion 18 is formed as much as possible. Therefore, according to the configuration of this embodiment, finer embroidery work can be performed without damaging the main skin piece SP1 as much as possible, and the appearance of the design portion 10 can be improved. Further, the design portion 10 can be more reliably reinforced by enclosing the design portion 10 with the reinforcing portion 20 composed of the plurality of reinforcing portions 21 to 24. Further, by forming the reinforcing portion 20 so as to border the design portion 10, the contour of the design portion 10 can be made to stand out by the reinforcing portion 10, which contributes to the improvement of the design of the design portion 10.

As described above, in the present embodiment, the seat cover 6S portion on which the dense portion 18 is formed is reinforced by overlapping the stitches of the design portion 10 and the stitches of the reinforcing portion 20 in a crossing manner. Therefore, in this embodiment, the seat cover 6S portion in which the dense portion 18 is formed is formed without particularly changing the configuration of the design portion 10 (arrangement position of the first hole portion H1, thickness of the design embroidery thread Y1, etc.). It is possible to maintain the strength as much as possible. Further, in this embodiment, the strength of the seat cover 6S portion in which the dense portion 18 is formed is increased by increasing the thread density by relatively increasing the distance (pitch) between the second hole portions H2 of the reinforcing portion 20.
