[Embodiment 1]
Embodiment 1 will be described with reference to FIGS. As shown in FIG. 1, the seat 10 according to the present embodiment is mainly composed of a seat back 12 serving as a backrest, a seat cushion 14 serving as a seating surface, and a headrest (not shown) that supports the head of the seated person. The present invention is applied to the seat back 12. The seat back 12 has an outer shape in which the central position where the seated person's back hits is substantially flat and both side portions are raised. The seat back 12 has a seat pad 20 (see FIG. 2) formed as an outer shape thereof and is mounted with a seat skin. The seat skin is formed into a bag shape by sewing a plurality of seat skins cut into different shapes so as to follow the three-dimensional outer shape of the seat pad 20. That is, the sheet skin 22 located in the center, the sheet skins 23 and 24 located on the side, the sheet skin 25 located on the side surface, and the like are sewn into a bag shape. The present invention is applied to the seat skin 22 constituting the outer surface of the substantially flat portion at the center of the seat back 12. Since the seat skin at other positions is not particularly required to be changed, a detailed description thereof will be omitted. Hereinafter, the seat skin 22 constituting the outer surface of the substantially flat portion at the center of the seat back 12 will be simply referred to as “sheet. The epidermis. Further, in the following description, the up / down / left / right direction of the seat skin 22 is determined with reference to the up / down / left / right direction viewed from the seated person of the seat 10. U and L indicated by arrows in the drawing indicate the upper side and the left side of the seat skin 22.

  The seat back 12 has a suspension structure 28 that divides a substantially flat portion at the center in the vertical direction. In the present invention, the suspending structure refers to a structure in which a linear member disposed in an integrated state with the seat skin on the back side of the seat skin is locked to the seat pad. As shown in FIG. 2, in the present embodiment, a linear member 50 made of a linear wire is disposed in an integrated state on the back side of the seat skin 22, and the linear member 50 is a seat pad. 20 is caulked by an engaging member 52 formed of a C-shaped ring on an insert wire 54 embedded under a groove portion 56 formed in the groove 20. The substantially flat portion at the center of the seat back 12 is provided with the same uniform skin pattern across both sections divided at the position of the suspension structure 28. The same pattern having uniformity across both sections is, for example, an elliptical pattern continuous in the vertical direction as shown in FIG. The seat skin 22 is disposed across both sections divided by the position of the suspension structure 28. The seat skin 22 is provided with pad covering portions 38 a and 38 b in which the portion covering the outer surface of the seat pad 20 is divided at the position of the suspension structure 28. And the sheet | seat outer skin 22 has the linear member arrangement | positioning site | part 32 which can insert the linear member 50 in the back surface side of the division position of pad coating | coated site | part 38a, 38b.

Hereinafter, the structure of the sheet skin 22 will be described while explaining the procedure for creating the sheet skin 22.
First, as shown in FIG. 3, the cutting piece 30 is cut from the original fabric. The sheet skin 22 is formed of a single cut piece 30 cut from the original fabric. That is, both the pad covering portions 38 a and 38 b and the linear member disposing portion 32 are formed from this single cutting piece 30. The cutting piece 30 is substantially rectangular, and the left and right symmetrical positions at the approximate center in the vertical direction of the rectangle are notched into a triangle to form notches 42a and 42b. The notches 42a and 42b are vertically symmetrical. Two holes 36a and 36b, which are shifted to the left and right, are formed inside the same position as the notches 42a and 42b when viewed in the vertical direction of the cutting piece 30. Each of the holes 36a and 36b is a vertically symmetrical circle. The vertical position in which the notches 42a and 42b and the holes 36a and 36b are formed is the division position of the cutting piece 30, that is, the division position of both pad covering portions 38a and 38b. In addition, two round holes 49 a and 49 b for inserting the headrest stay are formed symmetrically above the cutting piece 30.

Next, as shown in FIG. 4, the cutting piece 30 is bent with the back side facing outward at the division position. At this time, the vertically symmetrical holes 36a and 36b and the cutouts 42a and 42b are folded in half and overlapped with each other. And it sews in a straight line in the left-right direction at a certain width from the loop-shaped tip 32b of the cut piece 30 formed by bending. The cut piece 30 is spread in the vertical direction to complete the sheet skin 22. As shown in FIG. 5, the cutting pieces 30 are stitched together in a loop shape that does not spread even if the cutting pieces 30 are spread in the vertical direction by sewing with a certain width from the tip of the loop-shaped tip 32b. This loop-shaped part becomes the linear member disposition part 32. That is, it is bent so as to form a loop shape in the surface direction of the cutting piece 30 which is the back side of the sheet skin 22 at the divided position of the cutting piece 30, and the base end portion 32a of the loop shape is sewn, and the loop-shaped portion Is the linear member disposition site 32. In the linear member disposition site 32, the holes 36a and 36b previously formed in the cutting piece 30 remain as openings 40a and 40b.
In the sheet skin 22 created as described above, the linear member 50 is inserted into the linear member disposition site 32 on the back surface side, and both ends are folded back and retained, whereby the linear member 50 is integrated. It is arranged as. A part of the linear member 50 inserted through the linear member disposition site 32 is exposed from the openings 40a and 40b. The portions of the linear member 50 exposed from the openings 40a and 40b are locked to the insert wire 54 of the seat pad 20 via the locking member 52 (see FIG. 2).

According to the seat skin 22 having the above-described configuration, the following operational effects can be obtained.
By inserting the linear member 50 through the linear member disposition site 32, the linear member 50 can be easily disposed as an integral state with the sheet skin 22.
In addition, two pad covering portions 38 a and 38 b constituting the outer surface of the two sections divided by the position of the hanging structure 28 and the linear member disposing portion 32 on the back surface side are formed by a single cutting piece 30. Therefore, the number of parts constituting the seat skin 22 is small.
The cutting piece 30 is preliminarily formed with holes 36a and 36b and notches 42a and 42b that are symmetrical with respect to the virtual folding line 34 of the loop-shaped tip 32b for forming the linear member disposition site 32. Yes. Therefore, the cutting piece 30 can be bent at a predetermined position by bending the holes 36a and 36b and the notches 42a and 42b in half and matching the shapes thereof. Therefore, the linear member arrangement site 32 can be formed at a predetermined accurate position.
The sheet skin 22 is provided with the same uniform skin pattern across both sections divided at the position of the suspension structure 28, but it is also advantageous in that the skin pattern is difficult to shift. That is, when the sheet skin is completely divided at the division position, as shown by the two-dot chain line in FIG. 1, the skin pattern tends to shift in the left-right direction (longitudinal direction of the hanging structure 28). It is difficult to match the patterns. On the other hand, the sheet skin 22 is formed by a single cutting piece 30, and further, the holes 36 a and 36 b and the cutout portions 42 a and 42 b formed symmetrically with respect to the folding line 34. The shape is folded so as to be folded in half. Therefore, it is possible to easily match the skin pattern by accurately setting the relative positions of the pad covering portions 38a and 38b in both sections.
Further, since the linear member disposition site 32 is a loop-shaped portion formed by bending the cutting piece 30, the inserted linear member 50 is inserted into the seat pad 20 via the locking member 52. When locked to 54, both pad covering portions 38a, 38b can be evenly suspended. Therefore, the seat skin 22 is not easily loosened or entangled by the suspension structure 28, and the surface shape of the seat back 12 can be stabilized.

The seat skin 72 of the present embodiment constitutes the outer surface of a substantially flat portion at the center of the seat back 60. The seat back 60 has a suspension structure 62 that divides a substantially flat portion at the center in the vertical direction. The seat skin 72 is disposed across both sections partitioned by the suspension structure 62, and pad covering portions 74 a and 74 b that cover the outer surface of the seat pad 20 are partitioned by the position of the suspension structure 62. ing. And the sheet | seat outer skin 72 has the linear member arrangement | positioning site | part 76 in the back surface side of the division position of the pad coating | coated site | part 74a, 74b. The linear member 50 is inserted into the linear member disposition site 76, and the linear member 50 is caulked by a locking member 52 formed of a C-shaped ring on an insert wire 54 embedded in the seat pad 20. The above basic configuration is the same as that of the first embodiment.
Part of the pad covering portions 74 a and 74 b is drawn into the groove portion 56 of the seat pad 20, and as a result, the seat cover 72 is recessed in a groove shape at the set position of the suspension structure 62 as the surface shape of the seat back 12. It has a shape. This point is different from the first embodiment.

The sheet skin 72 is formed from one cut piece 80. The cutting piece 80 is bent so as to form a loop shape in the surface direction of the cutting piece 80 on the back side of the sheet skin 72, and the base end portion 76a of the loop shape is sewn. This loop-shaped portion is set as a linear member arrangement portion 76.
As shown in FIG. 8, the cutting piece 80 that forms the sheet skin 72 is substantially rectangular, and a loop-shaped tip 76 b that is formed by bending the cutting piece 80 to form the linear member disposition site 76. The left and right symmetrical positions on the virtual fold line 78 are cut out to form cutout portions 82a and 82b. The notches 82a and 82b are symmetrical with respect to the fold line 78 and have a shape in which the base shape rolls over. On the inner side of the fold line 78, holes 84a and 84b are formed by shifting the position to the left and right (the longitudinal direction of the fold line 78). The holes 84 a and 84 b have a circular shape that is symmetrical with respect to the folding line 78. Above the cutting piece 80, two round holes 86a and 86b for inserting the stay of the headrest are formed symmetrically.

  As shown in FIG. 9, the cutting piece 80 is bent and sewn at the division position with the back side facing outward. A linear member disposition site 76 is formed by sewing a predetermined width from a loop-shaped tip 76b where the cutting piece 80 is bent. The notches 82a and 82b are stitched along the notched ends. The sewing line of the linear member arrangement part (loop shape part) 76 and the sewing line of the notches 82a and 82b are different from each other, and the sewing line of the linear member arrangement part 76 is the tip of the loop shape. The position is recessed on the 76b side. In other words, the loop-shaped base end portion 76a of the linear member disposition site 76 is set at a position recessed toward the loop-shaped tip 76b side from the stitching position of the surrounding site. Therefore, a series of sewing lines are bent in a trapezoidal shape. As shown in FIG. 10, in the completed state of the sheet skin 72 in which the cutting piece 80 is expanded in the vertical direction, the loop-shaped base end portion 76 a is positioned so as to recede to the back surface side with respect to the surface of the sheet skin 72. doing.

  As shown in FIG. 7, the linear member 50 exposed from the openings 88 a and 88 b derived from the holes 84 a and 84 b formed in the cutting piece 80 is engaged with the insert wire 54 of the seat pad 20 by the locking member 52. When stopped, the loop-shaped base end portion 76a retracted to the back surface side is drawn into the groove portion 56 of the seat pad 20. According to the seat skin 72 of the present embodiment, as shown in FIG. 9, the loop-shaped base end portion 76 a of the linear member disposition site 76 is more than the stitching position of the region around the linear member disposition site 76. A groove-shaped design shape can be easily expressed simply by shifting the position toward the loop-shaped tip 76b.

The present invention is not limited to the above-described embodiment, and various other embodiments can be considered without departing from the gist of the present invention.
For example, the openings 40 a and 40 b may be formed later in the linear member disposition site 32 without providing the holes 36 a and 36 b in the cutting piece 30. However, if holes 36a, 36b that are symmetrical with respect to the fold line 34 for forming the linear member disposition site 32 are provided in the cutting piece 30 in advance, the fold line (fold line 34) becomes an index. Further, the notches 42a and 42b are not necessarily provided, but if they are provided, they serve as indices for the folding position (fold line 34). It is preferable that at least a cutout or a hole having a symmetrical shape with respect to the folding line 34 for forming the linear member disposition site 32 is formed in the cutting piece 30 in advance.
The present invention may be applied not only to the seat back 12 but also to the seat skin of the seat cushion 14.
Moreover, the usage form of the sheet | seat skin of this invention is not limited to the said embodiment. For example, as shown in FIG. 11, a linear member 92 integrally provided with a conical hook 90 is disposed in the linear member disposition site 32, and the linear member 94 embedded in the seat pad 20.
