Further, each of the shooting surface portions 11C and 12C formed on the first cover piece 11 and the second cover piece 12 described above has a barrel-shaped bulge shape of each of the expansion surface portions 11A and 12A described above in detail. The convex curved peripheral edge portions 11Aa and 12Aa to be formed and the peripheral edge portions 11Ba and 12Ba extending linearly in the longitudinal direction D of the band-like surface portions 11B and 12B are formed at the boundary portions where they abut each other. V-notches 11Cb and 12Cb projecting in a V-shape that indicate the positions of the folding lines 11Ca and 12Ca when these are sewn are formed on both sides of the respective sewn surface portions 11C and 12C.

  These V notches 11Cb and 12Cb indicate the positions of the polygonal lines 11Ca and 12Ca by their V-shaped vertices. As shown in FIG. 6, the respective stitching surface portions 11C and 12C are centered on the polygonal lines 11Ca and 12Ca. Each of the stitching surface portions 11C and 12C is folded in the shape of a valley fold so that each of the stitching surface portions 11C and 12C is folded over from the back side to the respective expansion surface portions 11A and 12A as shown in FIG.

  Specifically, the V notches 11Cb and 12Cb described above have peripheral portions facing the peripheral portions 11Aa and 12Aa of the respective expansion surface portions 11A and 12A when folded from the back side to the respective expansion surface portions 11A and 12A. These are formed in circular arc shapes whose shapes coincide with the peripheral portions 11Aa and 12Aa of the respective expansion surface portions 11A and 12A when folded. With such a configuration, the V notches 11Cb and 12Cb are folded from the back side on the above-described expansion surface portions 11A and 12A, so that the surface shapes of the expansion surface portions 11A and 12A are widely overlapped with each other. At the same time, it can be folded into a state where a wide seam allowance can be secured.

  As shown in FIG. 6, each of the above-described shooting stitching surface portions 11C and 12C is folded into a valley fold around the broken lines 11Ca and 12Ca as shown in FIG. The surfaces 11Cc and 12Cc are overlapped with each other, and as shown in FIG. 7, the surfaces are folded to the respective expansion surface portions 11A and 12A from the back side, and from this state, the surfaces 11Cc and 12Cc are overlapped with the respective expansion surface portions 11A and 12A. By being sewn together (seams 11Cd, 12Cd) with the respective expansion surface portions 11A, 12A at both side portions, the both sides are joined to each other on the back side of each expansion surface portion 11A, 12A. Here, the above-described valley surfaces 11Cc and 12Cc correspond to the “photographed surfaces” of the present invention.

  The seams 11Cd and 12Cd on both sides to be stitched with the respective expansion surface portions 11A and 12A of the respective photographing sewing surface portions 11C and 12C are the band-shaped surface portions 12B and 11B of the adjacent counterpart pieces of the respective expansion surface portions 11A and 12A. In the portion of the seam allowance that is outside the line through which the sewing line 13 to be sewn passes, it is sewn so as to extend in a curved shape along the arc shape of the peripheral edge portions 11Aa and 12Aa of the respective expansion surface portions 11A and 12A. As described above, the seam allowance area of the peripheral edge portions 11Aa and 12Aa that are outside the sewing line 13 of each of the expansion surface portions 11A and 12A described above is such that the V notches 11Cb and 12Cb of the respective sewing surface portions 11C and 12C are wide from the back side. Since the shapes are applied to each other, the stitches 11Cd and 12Cd with the respective stitching surface portions 11C and 12C can be prevented from being too close to the stitches.

  Then, the first cover piece 11 and the second cover piece 12 that have been stitched as described above, next, as shown in FIG. As shown in FIG. 9, the peripheral portions 11Aa and 12Aa of the inflating surface portions 11A and 12A swelled in a convex curve shape and the longitudinal directions of the mating belt-like surface portions 12B and 11B facing each other as shown in FIG. Sewing is performed through the needle M1 of the sewing machine M along the peripheral edge portions 11Ba and 12Ba extending linearly to D. At that time, the peripheral portions 11Aa and 12Aa of the respective expansion surface portions 11A and 12A and the peripheral portions 11Ba and 12Ba of the belt-like surface portions 11B and 12B have the same shape width H in the longitudinal direction D, but one ( Since the peripheral portions 11Aa and 12Aa of the expansion surface portions 11A and 12A are curved and the other (the peripheral portions 11Ba and 12Ba of the belt-like surface portions 11B and 12B) are linearly extended, the peripheral edges of the expansion surface portions 11A and 12A The circumferential length L1 along the portions 11Aa and 12Aa is longer than the circumferential length L2 along the peripheral portions 11Ba and 12Ba of the band-shaped surface portions 11B and 12B.

  Accordingly, in order to sew while making the above circumferential lengths L1 and L2 coincide with each other, as shown in FIG. 9, the belt-like surface portions 11B and 12B on the short circumferential side (circumferential length L2) While alternately extending to match the circumferential length L1 of each of the long expansion surfaces 11A, 12A, the peripheral portions 11Aa, 12Ba (11Ba, 12Aa) of the two are aligned along the sewing line 13 with a certain seam allowance. While trying to sew. As a result, as shown in FIG. 10, the peripheral portions 11Aa and 12Aa of the expansion surface portions 11A and 12A having different peripheral lengths and the peripheral portions 12Ba and 11Ba of the strip-shaped surface portions 12B and 11B facing each other are the same as each other. It can be sewn into a shape that is forcibly drawn to the circumference. At that time, the peripheral edge portions 11Aa, 12Aa of the respective expansion surface portions 11A, 12A and the peripheral edge portions 12Ba, 11Ba of the respective band-like surface portions 12B, 11B are always one of them (the peripheral edge portions of the respective band-like surface portions 11B, 12B). 11Ba, 12Ba) has a linearly extending shape, so that the other (peripheral portions 11Aa, 12Aa of the respective expansion surface portions 11A, 12A) can be sewn while simply aligning with the other side. .

  Moreover, since the 1st cover piece 11 and the 2nd cover piece 12 are set as the structure with the fixed tension which each consists of synthetic leather materials, peripheral part 11Aa of those expansion | swelling surface parts 11A and 12A, Even if a force is applied in the direction in which the seams 13A of the respective seam lines 13 running along 12Aa are shrunk, the generation of folds due to the seam is suppressed, and a finished shape with tension is sewn. It has become. Accordingly, the peripheral surface portions 11Aa and 12Aa of the respective expanded surface portions 11A and 12A having the convex curved peripheral shape that swells into a barrel shape by the above-described sewing have the peripheral surface portions 11B and 12B having the peripheral shape extending linearly in the longitudinal direction D. The peripheral portions 11Ba, 12B of the belt-like surface portions 11B, 12B are caused by the action of the repulsive force (repulsive force) associated with the peripheral portions 11Ba, 12Ba of the peripheral portions 11Ba, 12Ba being sewn in a contracted form. From 12Ba, it will be finished in a shape that rises to the front side in a rounded bulge shape.

  As a reaction, the peripheral portions 11Ba and 12Ba of the belt-like surface portions 11B and 12B each having a peripheral shape extending linearly in the longitudinal direction D have a convexly curved peripheral shape that swells into a barrel shape sewn thereto. By the action of the repulsive force (repulsive force) accompanying the stitching with the peripheral portions 12Aa and 11Aa of the inflating surface portions 12A and 11A, it is finished to be pushed down from the peripheral portions 12Aa and 11Aa of the inflating surface portions 12A and 11A to the back side. Become. Therefore, in combination with the above interaction, as shown in FIG. 2, the first cover piece 11 and the second cover piece 12 are formed such that each of the expansion surface portions 11A and 12A is a bulging convex surface, Each band-like surface portion 11B, 12B is formed as a concave concave surface, and is formed in a shape having a design pattern in which a three-dimensional pattern of unevenness extends in a lattice shape over the entire surface shape joined together. Is done.

  At that time, in each boundary portion between each of the inflated surface portions 11A and 12A serving as the convex surface and each of the band-shaped surface portions 11B and 12B serving as the concave surface of the first cover piece 11, both of the above-described stitching surface portions 11C and 12C are provided. Each of the valley surfaces 11Cc and 12Cc (see FIG. 6), the sides of which are sewn, form a stepped rising surface by the rising action due to the repulsive force (elastic force) generated between the above-described uneven surfaces. (See FIG. 2). Thereby, each uneven | corrugated shaped boundary part formed by each expansion | swelling surface part 11A, 12A and each strip | belt-shaped surface part 11B, 12B becomes a step-like rising surface, and stands out with good appearance.

<Summary>
In summary, the top plate main cover 10 (2Ca) of the present embodiment has the following configuration. That is, a vehicle trim cover (10) provided with a trim cover piece (11) sewn to an adjacent counterpart cover piece (12).

  The trim cover piece (11) has a sewing circumference (L1) longer than that of the mating cover piece (12), and is sewn into a shape in which the sewing circumference (L2) is combined with the mating cover piece (12). The mating cover piece (12) has a difference in the circumferential length of the sewing with respect to the first sewing surface portion (11A) to be attached and the mating cover piece (12) shorter than the first sewing surface portion (11A). Alternates in the direction (D) in which the sewing line (13) runs with respect to the other cover piece (12) and the second sewing surface portion (11B) sewn in a shape in which the circumference (L1) of the stitching is aligned with The shape has a repeated pattern repeatedly.

  Furthermore, the trim cover piece (11) has a bending rigidity capable of suppressing the occurrence of folds caused by stitch shrinkage that can occur between the plurality of seams (13A) running on each of the sewing surface portions (11A, 11B), Due to the bending rigidity, an indefinite shape is formed in which the rising shapes accompanying the difference in the circumferential length of the stitching surface portions (11A, 11B) with respect to the mating cover piece (12) are different from each other.

  With such a configuration, the rising shape from the mating cover piece (12) by the first sewing surface portion (11A) and the second sewing surface portion (11B) of the trim cover piece (11). Thus, it is possible to easily form a design pattern in which a three-dimensional pattern of unevenness is arranged in a single trim cover piece (11).

  In addition, one of the trim cover piece (11) and the mating cover piece (12) is composed of an extension member that can extend so as to absorb the difference in the circumferential length of stitching with the other. With such a configuration, the trim cover piece (11) and the mating cover piece (12), which have different circumferential lengths for sewing, are stretched to easily match the circumferential length for sewing. Can be sewn.

  Moreover, the 1st sewing surface part (11A) is made into the non-linear shape where circumference (L1) bends and extends in the direction which cross | intersects the direction (D) which a sewing line (13) runs. With such a configuration, it is possible to ensure a long sewing circumference (L1) without extending the first sewing surface portion (11A) in the running direction (D) of the sewing line (13). The trim cover piece (11) after sewing can be prevented from forming excessive slack.

  The sewing line (13) is an in-stitch. By adopting such a configuration, the sewing line (13) can be finished so as not to appear to the outside, and the sewing line (13) is sewn to the first sewing surface portion (11A) and the second sewing. It can be set as the structure which is easy to sew on which it runs continuously over a surface part (11B) straight.

  Further, the folding line (11Ca) runs in a direction that intersects the running direction (D) of the sewing line (13) between the sewing surface portions (11A, 11B) of the trim cover piece (11). It has a stitching surface portion (11C) which is folded in a ridge shape and the surfaces (11Cc) photographed on both ends of the polygonal line (11Ca) are joined to each other. By adopting such a configuration, the photographing sewing surface portion (11C) has a stepped shape between the first sewing surface portion (11A) and the second sewing surface portion (11B) having different rising shapes. Since the rising surface is formed, the boundary of the concavo-convex shape can be made to stand out in a step shape.

  Further, a V-notch (11Cb) that supports the position of the broken line (11Ca) is formed at the position where the stitching surface portion (11C) is photographed. By adopting such a configuration, it is possible to fold the photographed stitching surface portion (11C) at an appropriate position.

  Further, the second sewing surface portion extends in a shape in which the circumferential length (L1) of the first sewing surface portion (11A) swells in a convex curve shape in a direction intersecting the running direction (D) of the sewing line (13). The circumferential length (L2) of (11B) extends linearly along the direction (D) in which the sewing line (13) runs. With such a configuration, the first sewing surface portion (11A) can be finished so as to rise from the mating cover piece (12) in a rounded bulge shape toward the front side, and the first It is possible to sew the mating cover piece (12) on the second sewing surface portion (11B) while simply aligning the mating cover piece (12).

  Moreover, the other party cover piece (12) is also made into the shape with the same repeating pattern as the trim cover piece (11). The first sewing surface portion (11A) of the trim cover piece (11) is sewn with the portion (12B) corresponding to the second sewing surface portion of the counterpart cover piece (12), and the trim cover piece (11) The second sewing surface portion (11B) is sewn with the portion (12A) corresponding to the first sewing surface portion of the counterpart cover piece (12). With such a configuration, the combination of the trim cover piece (11) and the mating cover piece (12) allows the three-dimensional pattern of the concavo-convex shape to be in a lattice pattern across both cover pieces (11, 12). It is possible to form a design pattern lined up in a wide shape.

  Next, the configuration of the top plate main cover 10 (vehicle trim cover) of Example 2 will be described with reference to FIG. The top plate main cover 10 of the present embodiment does not have a configuration corresponding to the sewing surface portion (11C, 12C) shown in the first embodiment in the first cover piece 11 and the second cover piece 12, and each expansion The boundary portions between the surface portions 11A and 12A and the belt-like surface portions 11B and 12B are not configured to be stepped, but are changed to be inclined. Even with such a configuration, it is possible to form a design pattern in which a three-dimensional pattern of unevenness extends in a lattice pattern across the cover pieces 11 and 12 on the top plate main cover 10.

<< About other embodiments >>
As mentioned above, although embodiment of this invention was described using two Examples, this invention can be implemented with various forms other than the said Example. For example, the configuration according to the vehicle trim cover of the present invention can be widely applied to trim covers used for various vehicles such as aircraft and ships, as well as vehicles other than automobiles such as railways. . Further, the vehicle trim cover may be applied as a lining cover for various interior materials such as a door trim, in addition to the seat cover for the various seats described above.

  The vehicle trim cover can also be applied as a trim cover for other seat structures such as a seat cushion, a headrest, an ottoman, and an armrest, in addition to a seat back in a vehicle seat. Further, the vehicle trim cover may be placed on the top plate side, the kerchief or the back surface in addition to the top cover in the seat structure.

  Further, the trim cover piece and the counterpart cover piece may have different design patterns. Further, the trim cover piece has a longer circumference than the counterpart cover piece, and the first sewing surface portion that is sewn into a shape in which the circumference of the counterpart cover piece is combined is directed toward the counterpart cover piece. The shape may be a shape that bulges into a convex curve, or may be a shape that has a circumferential length increased by a shape that dents into a concave curve. Further, the circumferential length may be longer than that of the counterpart cover piece by being bent into a V shape instead of the uneven curved shape. Moreover, the 1st sewing surface part was made into the shape extended linearly along the direction where a sewing line runs, and the circumference may be made longer than the other party cover piece.

  Further, the second sewing surface portion sewn in a shape in which the circumferential length of the sewing is matched to the mating cover piece with a difference in the circumferential length of the sewing to the mating cover piece shorter than the first sewing surface portion. May not necessarily have a shape that extends linearly along the direction in which the sewing line runs, but may have a curved shape or a V-shaped shape. In addition, the first sewn surface portion and the second sewn surface portion may have different longitudinal widths. Moreover, the 2nd sewing surface part may be set as the structure by which the circumference of the sewing was made longer than the other party cover piece similarly to the 1st sewing surface part. The first sewn surface portion and the second sewn surface portion only need to have different circumferential length differences in the stitching with respect to the mating cover piece between the first sewn surface portion and the second sewn surface portion. The stitching surface portion may have an uneven shape with a concave side.

  Further, the trim cover piece and the counterpart cover piece may be made of a fabric material in addition to a leather material such as synthetic leather. Further, the trim cover piece and the counterpart cover piece may be made of different cover materials. Moreover, it is preferable that either the trim cover piece or the counterpart cover piece is an extension member capable of absorbing the circumferential length difference with the counterpart to be sewn together, but both are not necessarily extended from the extension member. It does not have to be.

  Moreover, the sewing method of the trim cover piece and the counterpart cover piece may be an out-stitch sewing method in which the sewing line is visible to the outside. Moreover, in the said Example, although the 1st cover piece 11 was shown as a structure corresponded to the "trim cover piece" of this invention, the 2nd cover piece 12 was shown as a structure corresponded to a "other party cover piece". Since these are configured to have a repeating pattern of the same unevenness, the second cover piece 12 corresponds to the “trim cover piece” of the present invention, and the first cover piece 11 corresponds to the “mating cover” of the present invention. Even the configuration corresponding to “piece” is substantially the same.
