Since this type of skin member is used as an exterior material for various products, it is desired to have excellent designability. Therefore, in the epidermis member, in addition to the epidermis having a basic appearance, a design portion having an appearance different from that of the epidermis is provided, and the design portion is improved in designability. For example, in the technique disclosed in Patent Document 1, a three-dimensional emblem is attached to the surface of a fabric corresponding to the epidermis of the present invention to improve the design. This three-dimensional emblem is a member formed of an inner sheet and a decorative cloth, and a specific character serving as a design part is three-dimensionally expressed. According to a known technique, an inner sheet and a decorative cloth are superposed on the surface of the fabric in this order, and the peripheral edge of the decorative cloth is sewn to the fabric to be attached. The inner sheet is an elastically stretchable resin foam, and its outer shape is arranged so as to express a specific character when viewed from the front. Therefore, by sewing the decorative cloth and the fabric so as to border the inner sheet, a part of the decorative cloth can be three-dimensionally raised so as to represent a specific character by the inner sheet.

Here, in the above-mentioned field of the skin member, there is a request that the skin member is subjected to various treatments to form a design portion from the viewpoint of further improving the design. For example, it is conceivable that the skin member is partially colored by sublimation printing processing, or the shape of the skin member is partially different by embossing or drilling. By forming the design portion by partially differentiating the color and shape of the skin member, the range of variations of the design that can be expressed is widened, and the structure contributes to the improvement of the design of the skin member.

Hereinafter, details of each configuration of the seat cover 6S and a manufacturing method will be described in detail.

[Basic configuration]
Here, the seat back 6 shown in FIG. 1 is formed by arranging a seat pad 6P (not shown) on a seat frame 6F (not shown) and then covering it with a seat cover 6S. The seat frame 6F is typically a substantially rectangular or arch-shaped frame in front view, and can be formed of a material having excellent rigidity such as metal or hard resin. The seat pad 6P is a member having an outer shape of the seat back 6, and can be formed of a foamed resin such as ^{polyurethane foam (density: 10 kg / m 3 to} 60 kg / m ^3). A seating portion 6a and a pair of left and right bank portions 6b and 6c are formed on the seating surface of the seat pad 6P. The seating portion 6a is a portion formed in the center of the seat width direction (left-right direction in FIG. 1) on which an occupant can be seated, and has an appropriate left-right width dimension and extends in the vertical direction. Further, the bank portion 6b on the right side and the bank portion 6c on the left side are portions that rise in a mountain shape relatively forward on the side of the seating portion 6a.

[Seat cover (skin member), skin]
The seat cover 6S shown in FIG. 1 is a face material corresponding to the skin member of the present invention, and is formed by suturing a plurality of skins 61S to 63S. For example, on the front surface of the seat cover 6S, the main skin 61S covering the seating portion 6a, the right side skin 62S covering the right bank portion 6b, and the left side skin 63S covering the left bank portion 6c are sewn together. Is formed of. As the material of each of these skins 61S to 63S, a face material that can form the design surface of the sheet can be used. For example, leather (natural leather, synthetic leather), synthetic fiber, or cloth made of synthetic fiber or natural fiber (woven fabric, knitted fabric, etc.) can be used. Non-woven fabric) can be appropriately selected and used. The basic appearance (basic appearance) of the seat cover 6S is composed of the skins 61S to 63S, and the main skin 61S corresponds to the skin of the present invention, to which a planar member 10 described later is attached.

[Surface member]
The planar member 10 shown in FIGS. 2 and 3 is a planar member smaller than the main skin 61S, and is retrofitted to the lower left of the main skin 61S. Peripheral portions 10a to 10d of the planar member 10 are formed so as to form a parallel four-sided shape when viewed from the front. That is, in the planar member 10, the upper edge portion 10a and the lower edge portion 10b forming the peripheral edge portion extend horizontally in the left-right direction, and the right edge portion 10c and the left edge portion 10d forming the peripheral edge portion extend from the bottom to the top. It gradually slopes to the left as it goes. A pair of left and right embroidery portions 21 and 22 and a pair of left and right design portions 31 and 32 are formed on the outer surface 10x of the planar member 10 and are exposed to the outside. Further, the back surface 10y and the peripheral edge portions 10a to 10d of the planar member 10 are retrofitted and attached to the main skin 61S via the attachment portion 40 and the attachment member 50 described later.

[Material of planar member]
Here, as the material of the planar member 10, a material that is less deformed by external stimuli such as heat and external force can be used as compared with the main skin 61S, and it is particularly desirable that the material is less deformed by heat. Note that the transformation means that the appearance (appearance, feel, etc.) changes solely due to changes in physical properties, and it can be assumed that hardening, discoloration, wrinkles, or slackening occurs due to melting during heating. As this type of material, a cloth made of synthetic resin having a high melting point and excellent heat resistance can be used. For example, when assuming the sublimation printing process described later, a resin having a melting point of 180 ° C. or higher is preferable, and a melting point of 200 ° C. or higher is preferable. It is more preferable that the resin is. Examples of this type of synthetic resin having excellent heat resistance include polyester resin, polyamide resin, triacetate resin, acrylic resin, polypropylene resin, and a mixed resin thereof. For example, in this embodiment, assuming the sublimation printing process described later, a cloth made by weaving or knitting polyester resin fibers having excellent heat resistance and dyeability is used as the material of the planar member 10. Examples of the polyester resin include polybutylene terephthalate resin (melting point 223 ° C.), polyethylene terephthalate resin (melting point 260 ° C.), and polybutylene naphthalate resin (melting point 243 ° C.), and these may be used alone or in combination of two or more. Can be done. The content of the polyester resin is not particularly limited as long as the sublimation dye described later can be fixed, but it is typically desired to contain 50 wt% to 100 wt% of the polyester resin with respect to the total weight of the planar member 10. Stainability can be ensured.

[Embroidery part]
The pair of left and right embroidery parts (right side embroidery part 21, left side embroidery part 22) shown in FIGS. 2 and 3 are parts in which the embroidery thread Y0 is embroidered into a specific shape, respectively, by machine embroidery using a sewing machine or the like. Can be formed. Here, the forming method (embroidery method) of each embroidery part 21 and 22 is not particularly limited, but for example, at least one of tatami stitching, satin stitching and stitch stitching can be used, and each method can be used in combination. it can. Then, in this embodiment, the right embroidery portion 21 has a substantially circular pattern when viewed from the front, is formed on the right side of the planar member 10, and is exposed on the outer surface 10x. Further, the left embroidery portion 22 has a substantially square pattern when viewed from the front, is formed on the left side of the planar member 10, and is exposed on the outer surface 10x. The color of each embroidery portion 21 or 22 can be defined exclusively by the coloring of the embroidery thread Y0, and it is desirable that the color is different from that of the main skin 61S so as to be relatively conspicuous. For example, in each of the embroidery parts 21 and 22 of this embodiment, a white embroidery thread Y0, which is a color different from that of the main skin 61S, is used, and this white color is also a color that is difficult to express by the sublimation printing process described later. The material of the embroidery thread Y0 is not particularly limited, but for example, an exemplary material can be used for the planar member, and it is desirable to include a polyester resin as in the planar member in consideration of dyeability.

[Each design part]
The pair of left and right design parts (right side design part 31, left side design part 32) shown in FIGS. 2 and 3 are colored parts provided on the outer surface 10x of the planar member 10, respectively, and are formed by fixing the sublimation dye. Has been done. This sublimation dye is an ink used in the sublimation printing process described later, and can express various colors by appropriately combining, for example, yellow (Y), magenta (M), and cyan (C). When coloring the design parts 31 and 32, it is desirable to select a color different from the main skin 61S and the corresponding embroidery parts 21 and 22 so as to be relatively conspicuous. For example, in this embodiment, two different colors (first color C1, second color C2) are selected as different colors from the main skin 61S and the embroidery parts 21 and 22 (in each figure, they are colored for convenience). A hatch is attached to the part where it is, and in particular, in FIG. 2, the difference in color is shown by the difference in hatch). When the outer surface 10x of the planar member 10 is bisected to the left and right, the right side design portion 31 is formed on the right side of the planar member 10 and the left side design portion 32 is formed on the left side of the planar member 10. The right side design portion 31 is colored by selecting the first color C1 and is provided on the right side of the planar member 10 so as to surround the right side embroidery portion 21 (the arrangement relationship between the design portion and the embroidery portion will be described later). Further, the left side design portion 32 is colored by selecting the second color C2, and is provided on the left side of the planar member 10 so as to surround the left side embroidery portion 22.

[Arrangement relationship between embroidery parts and each design part]
By the way, the outer shapes of the embroidery portions 21 and 22 shown in FIGS. 2 and 3 are formed by arranging the stitches of the embroidery thread Y0 so as to form a predetermined design. For this reason, each of the embroidery parts 21 and 22 has an outer shape generally as intended, but the outer edge side that forms the outline of the design cannot always accurately express the design. For example, the right embroidery portion 21 has a substantially circular shape, but on the outer peripheral edge 21a side thereof, the stitch end (E) of the embroidery thread Y0 shown in FIGS. 4 and 5 has an appearance of protruding slightly. It is inevitable that the shape will be uneven (in FIG. 5, for convenience, the reference numerals Y0 and (E) corresponding to the stitches of only one embroidery thread are attached).

Therefore, in this embodiment, the right design portion 31 shown in FIGS. 4 and 5 is formed so as to partially overlap the right embroidery portion 21 to make the outer peripheral edge 21a side of the right embroidery portion 21 inconspicuous. There is. That is, the inner edge portion 31a of the right side design portion 31 has a sharp circular shape with relatively no unevenness, and is formed on the outer peripheral edge 21a of the right side embroidery portion 21 so as to hide the stitch end portion (E) of the embroidery thread Y0. It is a duplicate. By arranging the edge E1 of the inner edge portion 31a of the right side design portion 31 inward of the stitch end portion (E) of the embroidery thread Y0, the outside of the right side embroidery portion 21 has a sharper circular edge. It can be represented by the end E1. Similarly, the left design portion 32 shown in FIGS. 2 and 3 is also formed so as to partially overlap the left embroidery portion 22 so that the outer peripheral edge 22a side of the left embroidery portion 22 is made inconspicuous. That is, the inner edge portion 32a of the left side design portion 32 has a sharp square shape with relatively no unevenness, and overlaps with the outer peripheral edge 22a of the left side embroidery portion 22. Therefore, the outside of the left embroidery portion 22 can also be represented by the edge of the inner edge portion 32a of the left side design portion 32 having a sharper square shape.

[Attachment part]
The sticking portion 40 shown in FIG. 3 is a portion where the back surface 10y of the planar member 10 is attached to the outer surface 61x of the main skin 61S and is brought into close contact with the outer surface 61x, and may be provided between the main skin 61S and the planar member 10. it can. By attaching the planar member 10 to the main skin 61S with the attaching portion 40, it is possible to avoid a situation in which the planar member 10 is excessively lifted from the main skin 61S as much as possible, and the planar member 10 can be arranged in a good-looking manner. It becomes. As this type of sticking portion 40, various members that can be interposed between the main skin 61S and the planar member 10 can be used, for example, a planar or linear adhesive member, an adhesive layer with an adhesive, or the like. A hanging member such as a sticking layer or a hook-and-loop fastener can be used. The sticking portion 40 of this embodiment is formed of a planar adhesive member 41 having an adhesive layer on the front and back surfaces, and the adhesive member 41 has an appropriate thickness so that the planar member 10 does not rise extremely. doing. Then, the front surface of the adhesive member 41 is adhered to the back surface 10y of the planar member 10, and the back surface of the adhesive member 41 is adhered to the outer surface 61x of the main skin 61S. In this way, by utilizing the adhesive force of the planar adhesive member 41 to bond both the planar member 10 and the main skin 61S so that they are relatively firmly adhered to each other, the planar member 10 can be removed from the main skin 61S. It is possible to avoid the situation of floating up more surely. Further, when the embroidery portions 21 and 22 are provided on the planar member 10 as in the present embodiment, the embroidery portions 21 and 22 are reinforced by the adhesive member 41 so that the embroidery thread Y0 is less likely to be unraveled or damaged. It becomes.

[Mounting member]
The mounting member 50 shown in FIGS. 2 to 4 is a member that mounts the peripheral edges 10a to 10d of the planar member 10 to the main skin 61S. As this type of mounting member 50, a member capable of physically joining the planar member 10 and the main skin 61S can be used, and various threads such as embroidery thread Y1 for retrofitting and a hooking member such as a hook-and-loop fastener can be used. Can be exemplified. For example, in this embodiment, the peripheral edges 10a to 10d of the planar member 10 are sewn to the main skin 61S in a state of being bordered by the embroidery thread Y1 for retrofitting as the mounting member 50. Here, as the embroidery method, various methods such as satin stitching, tatami stitching, and stitch stitching can be exemplified, and it is preferable to use satin stitching, which makes it easy to manage the pitch (seam length) and the like. Therefore, in this embodiment, the satin stitching of the embroidery thread Y1 for retrofitting as the mounting member 50 is formed so as to form a rectangular embroidery pattern while edging the peripheral edges 10a to 10d of the planar member 10. In this way, the satin stitch embroidery pattern of the embroidery thread Y1 for retrofitting is formed so as to form a part of the design of the main skin 61S, which contributes to the improvement of the design of the seat cover 6S.

[Manufacturing method of seat cover (skin member)]
As described above, the seat cover 6S shown in FIGS. 1 and 2 includes a main skin 61S and the like having a basic appearance, design portions 31 and 32, and embroidery portions 21 and 22. Each of the design parts 31 and 32 is formed by a sublimation print process as described later, but in this type of configuration, the main skin 61S may be damaged by an external stimulus during the process. It should be avoided as much as possible. Therefore, in the seat cover 6S of the present embodiment, after the design portions 31 and 32 are formed on the planar member 10, the planar member 10 is retrofitted to the main skin 61S via the mounting member 50. That is, in this embodiment, the seat cover 6S is treated with various external stimuli by the first step and the second step, which will be described later, without damaging the main skin 61S as much as possible. Hereinafter, a method of manufacturing the seat cover 6S will be described with reference to FIGS. 6 to 9 by taking the main skin 61S and the planar member 10 shown in FIGS. 2 and 3 as examples.

[First step]
In the first step shown in FIG. 6, the surface member 10 which is less deformed by an external stimulus than the main epidermis is subjected to a sublimation print process (process accompanied by an external stimulus) described later to be applied to each design portion 31, 32. To form. In this first step, as shown in FIG. 7, a base material 100X which is a raw material of the planar member 10 is prepared. The base material 100X is a face material having a larger area than the surface member 10, and is formed of a cloth containing a polyester resin like the surface member 10. Therefore, in this embodiment, after forming the embroidery parts 21 and 22 on the portion of the base material 100X that becomes the planar member 10 (hereinafter, referred to as the reference portion 10X), each design portion is subjected to the sublimation printing process described later. 31 and 32 are formed (in FIG. 7, for convenience, reference numerals 31 and 32 indicating the design parts are attached to positions where each design part of the planar member should be formed).

[Sublimation print processing (formation of each design part)]
Here, in the sublimation printing process, as shown in FIG. 7, a transfer member 60 on which the sublimation dye is fixed is prepared. The transfer member 60 is a face material having an outer shape that fits in the reference portion 10X, and can be formed of a film or sheet containing a polyester resin or the like. When the transfer member 60 is divided into two equal parts on the left and right sides, the first color C1 for forming the right side design portion 31 is preliminarily fixed on the substantially entire surface of the right side portion 61. Further, the right side portion 61 is provided with a circular right side through hole 61H that follows the right side embroidery portion 21, and the peripheral edge portion 61a forming the peripheral edge of the right side through hole 61H overlaps with the outer peripheral edge 21a of the right side embroidery portion 21. It is formed. Further, the left side portion 62 of the transfer member 60 is preliminarily fixed with the second color C2 for forming the left side design portion 32 on substantially the entire surface thereof. The left side portion 62 is provided with a square left through hole 62H that imitates the left embroidery portion 22, and the peripheral edge portion 62a of the left through hole 62H is formed so as to overlap the outer peripheral edge 22a of the left embroidery portion 22. ing.

Then, in the sublimation printing process, the sublimation dye of the transfer member 60 shown in FIG. 6 is transferred to the reference portion 10X of the base material 100X by the heat press device 70. At this time, the base material 100X and the transfer member 60 are placed on the pedestal portion 71 of the heat press device 70 in this order. Then, the base material 100X and the transfer member 60 in this state are heated while being pressurized by the press portion 72 of the heat press device 70. The heating temperature of the sublimation printing process is not particularly limited as long as the sublimation dye can be sublimated (vaporized), but is typically set in the range of 160 to 200 ° C. (preferably 180 ° C.). The set pressure is not particularly limited as long as a pressing force capable of bringing the transfer member 60 and the base material 100X into close contact with each other can be obtained, but can be typically set in the range of 0.01 MPas to 10 MPas.

Then, referring to FIGS. 6 and 7, the right side portion 61 of the transfer member 60 is pressed against the right side of the reference portion 10X in the base material 100X by the pressurization of the press portion 72. In this state, the sublimation dye (first color C1) of the right side portion 61 is sublimated by heat and transferred, so that the right side design portion 31 can be formed on the right side of the reference portion 10X. At this time, the sublimation dye is not transferred to the right embroidery portion 21 exposed from the circular right through hole 61H, so that the appearance remains as it is. Further, in the right side portion 61, the peripheral edge portion 61a of the right side through hole 61H overlaps with the outer peripheral edge 21a of the right side embroidery portion 21, and in this state, the sublimation dye (first color C1) is applied to the outer peripheral edge 21a of the right side embroidery portion 21. Transferred. That is, the peripheral portion 61a of the right side through hole 61H forms the inner edge portion 31a of the right side design portion 31 shown in FIGS. 4 and 5.
