Moreover, a lattice pattern can be provided with respect to a leather product by providing a some stitch part on a base material in cross shape. However, when using a stitch portion and a design portion in combination, one design of the stitch portion and the design portion may be restricted by the other design. For example, when an attempt is made to form a design part on the stitch part, there is a concern that the stitch thread may be damaged when the design part is formed. For this reason, the stitch portion is formed to avoid the design portion, but this restricts the design of the stitch portion. For example, when the stitch part is bent in an unnatural direction in the vicinity of the design part or is interrupted in the vicinity of the design part, the design of the stitch part is deteriorated.

  Here, in the technique of Patent Document 1, a fray prevention structure is provided on the base material, and the fray prevention structure prevents fraying of the sewing start and end points of the stitch portion. The fray-retaining structure is a substantially rectangular area composed of a heat-meltable yarn, and is formed by sewing the heat-meltable yarn to a substrate. The stitch portion is formed so as to cross the fraying prevention structure, and the sewing start and sewing end portions of the stitch portion are arranged in the fraying prevention structure. The heat melting yarn is heated and fused to the sewing thread of the stitch portion to prevent the fray of the end of the stitch portion. Therefore, it is conceivable to use a heat melting yarn as a constituent yarn of the design part and to reinforce the stitch part by fusion of the heat melting yarn of this design part.

For example, it is possible to form various patterns (patterns imitating specific animals, articles, etc., geometric patterns) in the design department, and when using the design department as a logo, it is possible to form specific characters. It can also be configured. And the periphery of a design part can take various shapes, such as linear form, curved shape, and step shape (step or zigzag shape) according to the shape (contour) of a design part. Further, the design portion can be constituted by at least one of satin sewing and satin sewing, and can also be constituted by both satin sewing and satin sewing. For example, as a design portion, a satin-stitched pattern, characters, etc. can be formed on a satin-stitched pattern, and vice versa. And according to this embodiment, it is possible to set it as the composition which does not give restriction to the design of the pattern of a satin-sewing by arranging the end region of each stitch part on the periphery of a Tatami-sewn, and vice versa. In addition, when forming a design part, the base stitch which shows the external shape of a design part roughly can also be given to a base material.

  Further, in the present embodiment, the configuration (shape, size, arrangement position, number of formation, orientation of the stitch portion, etc.) of each of the stitch portions STa to STj etc. is illustrated, but it is not intended to limit the configuration of the stitch portion. For example, the stitch portion can be used not only as a quilting stitch, but also as various stitches formed on a substrate (for example, a stitch for stitching substrate pieces), and can also be used as a mere decoration. In addition, a plurality of or single stitches can be provided in the base material, and the extension direction of the stitches can be appropriately selected. Further, the stitch portion can be extended in a curved shape or a step-like shape, in addition to the case where it is extended linearly. The stitch portion can be overlapped at an appropriate position on the periphery of the design portion. For example, in the design portion of this embodiment, the stitch portion is overlapped to at least one of the upper edge, the lower edge, the right edge and the left edge. It is possible to In the case of forming a plurality of stitched parts, it is possible to arrange various lattice patterns, and as lattice patterns, in addition to hycyclos, an irregular triangle lattice, an orthorhombic lattice, a square lattice, a rectangular lattice, a parallel lattice A lattice pattern such as a body lattice can be assumed. It is also possible to form a plurality of stitch portions without crossing each other. In addition, a stitch part can also be formed after formation of a design part.

  Further, in the present embodiment, the configuration (shape, size, arrangement position, configuration of each portion, etc.) of the terminal portion 32 is exemplified, but the configuration of the terminal portion is not limited. For example, the terminal part can be formed separately from each part as shown in FIG. That is, at the end portion (first return portion), the stitch extends in the direction opposite to the extension direction of the stitch portion, but in the reverse direction, it is completely opposite (overlapping) in the extension direction. It is sufficient that the direction is substantially along the extending direction, and a slight shift (a shift in the left-right direction in FIG. 5) is allowed. Similarly, at the end part (second return part), the seam extends in the same direction as the extension direction of the stitch part, but this same direction is completely the same as the extension direction (overlapping). Besides, it may be a direction substantially along the extension direction, and a slight displacement (a displacement in the lateral direction in FIG. 5) is acceptable.

  In addition to the case where the inner site, the first return site and the second return site are all overlapped and arranged, at least two sites can be overlapped and arranged. In addition, the length and number of stitches constituting the inner portion, the first turning portion, and the second turning portion (the length dimension of each portion) can be appropriately changed, and the length and number of the stitches are different in each portion. It may be. The end portion can also be formed by performing a backstitching process in which four or more backstitched yarns are overlapped. For example, in the terminal part, another first return part or another second return part can be provided subsequent to the second return part. For example, the terminal part is located at the first return part arranged next to the second return part. Can also be provided. The end portion may be formed at the end of at least one of the stitch start and the end of the stitch, and may be formed at only one end of the start and the end of the sewn. Moreover, in a terminal part, it can be set as the structure by which it folds back in the same direction as the extension direction within a design part, after a seam is extended in the reverse direction with respect to the extension direction of a stitch part.

  Further, in the present embodiment, the configuration of the present embodiment has been described using the vehicle seat 2 as an example, but the configuration of the present embodiment can be applied to various members including leather. That is, as leather products, vehicle interior goods, household interior goods, clothes miscellaneous goods such as bags and bags can be exemplified. Moreover, the base material may be comprised only by the front side base material. In addition to the vehicle seat, various members such as a door, an instrument panel, a ceiling, and a console can be exemplified as the vehicle interior parts, and the configuration of this embodiment is mounted on a vehicle such as a vehicle, an aircraft, a train, and a ship. It can be applied to the vehicle interior parts to be In the vehicle seat, in addition to the seat back, the configuration of the present embodiment can be applied to a seat cushion and a seat cover of various seat components such as a headrest and an armrest. And the structure of a design part and a stitch part can be suitably changed according to the kind of leather product.
