<About back cover 2C>
The back cover 2C described above was laminated and adhered to the fabric skin material 2Ca, the polyurethane foam lami pad 2Cb laminated and adhered to the back surface of the skin material 2Ca, and the back surface of the lami pad 2Cb. The back base fabric 2Cc is constituted by a three-layer structure. The above-described back cover 2C is configured such that a plurality of cover pieces having the above-described three-layer structure are joined together in a single bag shape that can cover the entire surface of the back pad 2P. The above-described back cover 2C is in a state of being stretched so as to be in close contact with the entire surface of the above-described back pad 2P.

<About Cushion Cover 3C>
Similarly, the cushion cover 3C was laminated and adhered to the fabric skin 3Ca, the polyurethane foam lami pad 3Cb laminated and adhered to the back and back of the skin 3Ca, and the back and back of the lami pad 3Cb. The back base fabric 3Cc is constituted by a three-layer structure. The cushion cover 3C described above is configured such that a plurality of cover pieces having the above-described three-layer structure are joined together in a single bag shape that can cover the entire surface of the cushion pad 3P. The cushion cover 3C described above is in a state of being stretched so as to be in close contact with the entire surface of the cushion pad 3P described above.

<About ribbon tape 10>
On the other hand, the ribbon tape 10 is configured to be formed into a thick band shape by multiple weaving of dyed polyester color yarns. Specifically, the ribbon tape 10 includes a surface layer portion 11 and a back layer portion 12 which are woven by crossing warp yarns 10P and weft yarns 10T as shown in the structure diagram of FIG. This is a multi-woven structure in a form having two layers of front and back. Specifically, in the ribbon tape 10, each weft 10T woven in a shape intersecting from the front and back two directions with respect to each warp 10P constituting the surface layer portion 11 is composed of each warp constituting the back layer portion 12 in some places. By being woven into a shape that also interlaces with 10P, the surface layer portion 11 and the back layer portion 12 are woven into a laminated shape that is integral with each other.

  More specifically, the surface layer portion 11 of the ribbon tape 10 has a configuration in which each weft 10T intersects with each warp 10P. On the other hand, the back layer portion 12 of the ribbon tape 10 intersects with the first region 12A woven in such a manner that each weft 10T intersects with each warp 10P. The configuration is woven into a shape having the woven second region 12B. By having such a structure, the back layer portion 12 is formed so that each weft 10T constituting the above-described second region 12B is located between the intersections with each warp 10P rather than each weft 10T constituting the first region 12A. The lateral width (width length) that can be freely deformed is wide, and the degree of freedom of deformation that can be stretched or loosened in the band width direction is increased.

  The back layer portion 12 has a configuration in which the first region 12A and the second region 12B described above are woven in a form alternately arranged in the band width direction. Thus, the back layer portion 12 has a configuration in which the above-described second region 12B is arranged in a widely distributed manner at regular intervals over the entire width direction, so that it is more than the surface layer portion 11. The structure is excellent in stretchability in the width direction. With such a configuration, the ribbon tape 10 can be placed on the outer peripheral side of the curved portion even when the ribbon layer 10 is bent to a shape in which the cross-sectional shape is curved by applying a load to the surface layer portion 11 from the outside. Since the 12 stretches smoothly, the circumferential difference generated between the surface layer portion 11 and the surface layer portion 11 is suitably absorbed by the back layer portion 12 so that the whole can be flexed flexibly.

  On the other hand, the surface layer portion 11 has a configuration in which each weft 10T intersects with each one of the warp yarns 10P, so that the component yarns are rubbed against external rubbing. It is difficult to shift and has a relatively high durability. The wefts 10T extending so as to be entangled with the warp yarns 10P of the back layer portion 12 from the surface layer portion 11 are entangled with the warp yarns 10P constituting the first region 12A of the back layer portion 12 described above. The warps 10P constituting the two regions 12B are woven so as not to be entangled. With this configuration, the surface layer portion 11 can be connected to the back layer portion 12 over the entire region in the band width direction at a constant interval, while the back layer portion 12 It is possible to prevent the extensibility of the two regions 12B from being hindered.

  As shown in FIG. 2, the above-described ribbon tape 10 has the cover pieces 2C1, 2C2 (back cover 2C (cushion cover 3C)) connected to the left and right sides of the cover piece 2C1, C2 ( The cover piece 3C1, 3C2) is thicker than the skin material 2Ca (skin material 3Ca). The ribbon tape 10 described above is joined to the cover pieces 2C1 and 2C2 (cover pieces 3C1 and 3C2) joined to the left and right sides of the ribbon tape 10 by sewing the edges on the respective sides as follows. .

  That is, the ribbon tape 10 has an edge on each side in the band width direction (sheet width direction) with respect to the edge of each cover piece 2C1, 2C2 (cover piece 3C1, 3C2) to be joined together. The seam allowances are sewn by in-stitch 10A along each edge in a state where the seam allowances are folded back to the back side.

  Further, each seam allowance of the edge of each side of the ribbon tape 10 thus sewn and the edge of each cover piece 2C1, 2C2 (cover piece 3C1, 3C2) is overlapped with each cover piece 2C1, 2C2. Each of the cover pieces 2C1, 2C2 (cover pieces 3C1, 3C2) is folded by an out stitch 10B which is folded back so as to be superimposed on the back side of the (cover pieces 3C1, 3C2) and sewn along the above-described in stitches 10A. ) Is sewn on each edge.

  As described above, the ribbon tape 10 sewn in a form spanned between the cover pieces 2C1 and 2C2 (cover pieces 3C1 and 3C2) has a structure with increased rigidity and is formed with a thick structure. Even if a tension is applied from the pieces 2C1 and 2C2 (the cover pieces 3C1 and 3C2) toward the outer sides in the width direction, there is no recumbency, twisting or bumping between them, and the position is on the back side. The back pad 2 </ b> P (cushion pad 3 </ b> P) is held in a flat surface shape in wide surface contact.
