It is in a state.

Japanese Patent No. 4432383

  However, in the above prior art, although a highly rigid ball edge core material is stitched to the stitched portion between the cover pieces, the ball edge core material is stitched to the portion of the seam allowance away from the stitched portion. It is not possible to properly suppress the meandering of the stitching line that occurs at the stitched portions. The present invention was devised as a solution to the above-mentioned problem, and the problem to be solved by the present invention is to appropriately suppress the meandering of the stitching line that occurs at the stitched portion between the cover pieces. There is.

In order to solve the above problems, the vehicle seat cover of the present invention takes the following means.
A first invention is a vehicle seat cover including two cover pieces stitched together, a stitched portion that is stitched together and exposed as a stitching line to the outside, and a stitching And a core member that is sewn together with two cover pieces and suppresses meandering of the stitching line due to its rigidity.

  According to the first aspect of the invention, the meandering of the stitching line generated at the stitched portion between the two cover pieces can be appropriately suppressed by the rigidity of the core member sewn together with the two cover pieces.

  The second invention is the following configuration in the first invention described above. The core member is finished to have a rounded cross-sectional shape in which an end surface that hits one of the two cover pieces from the back side is curved in the joining direction of the two cover pieces.

  According to the second aspect of the invention, the end face of the core member is less likely to appear as a highlight on the surface of the two cover pieces, so that the meandering of the sewing line can be suppressed without impairing the appearance.

  The third invention is the following configuration in the first or second invention described above. The core member is composed of a ball edge core and a bag material that wraps the ball edge core inside, and the bag material is sewn together with two cover pieces at the stitching portion, thereby sewing together the rigidity of the ball edge core. It has a structure that suppresses meandering of the line.

  According to the third aspect of the invention, the core member is appropriately sewn to the two cover pieces while having rigidity by wrapping the rim core in the bag material and stitching it to the two cover pieces. It can be set as the structure which can do.

  According to a fourth invention, in any one of the first to third inventions described above, the following configuration is adopted. An arrangement in which one of the two cover pieces is formed in a curved shape at the peripheral edge, and the core member is positioned on the outer peripheral side of the curved stitching portion where the one peripheral edge and the other peripheral edge are overlapped and stitched. Has been.

  According to the fourth aspect of the invention, the core member is positioned on the outer peripheral side of the stitching portion so that the stitching portion has a curved shape having a longer circumference than the stitching portion due to the tension applied between the two cover pieces. Since it comes to be pressed against the core member, the stitched portion is in a state of being stretched so as to widen the heel rather than narrowing the circumference and causing the heel to approach. Therefore, both the meandering of the sewing line and the generation of wrinkles at the stitched portion can be appropriately suppressed by the arrangement of the core member.

It is a perspective view of a seat cover simple substance. It is the perspective view which visualized the back side structure of the seat cover.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

  First, the configuration of the seat cover according to the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the seat cover of this embodiment is configured as a cloth back cover 10 placed on the surface of a seat back 2 of a seat 1 of an automobile. The back cover 10 is provided by being covered with a foamed urethane back pad 20 (cushion material) provided in the seat back 2 from the front side.

  Specifically, after the back cover 10 is put on the back pad 20 from the front side, the upper, lower, left, and right peripheral edges are pulled rearward so as to surround the peripheral edges of the back pad 20 from the outer peripheral side. It is provided in a state of being fixed and fixed to a frame (not shown). By being provided in this manner, the back cover 10 is stretched in a good-looking state with no floating or wrinkles with respect to the back pad 20 as a state where the back cover 10 is put in a state of being in close contact with the surface of the back pad 20. It is supposed to be installed.

  The back cover 10 described above is configured by sewing a plurality of cover pieces 10A cut in accordance with the shape of each surface of the back pad 20 into a single bag shape. In the back cover 10, the stitching line 10 </ b> B between the cover pieces 10 </ b> A described above comes on the streak-shaped concave strips 21 formed along the corners of the boundary between the surfaces of the back pad 20. Thus, it is in a state of being aligned and stretched. Since the back cover 10 is stretched in this way, the seam allowances 11A and 12A overhanging the back side of the stitched stitching line 10B between the cover pieces 10A described above are formed on the concave portions of the back pad 20. 21 is a state in which the cover piece 10 </ b> A is stretched in a good-looking state that does not cause highlights in the middle of the stretched surface.

  Here, the back cover 10 described above is a stitched stitch line of a cover piece 11 that covers the upper region of the lateral side surface of the seat back 2 and a cover piece 12 that covers the peripheral region of the upper surface of the seat back 2. 14A has a shape curved in an inverted U-shape along the shape of the corner at the boundary between the lateral side surface and the upper surface of the seat back 2. Even if such a sewing line 14A between the cover pieces 11 and 12 does not have a curved shape as described above, the cover pieces 11 and 12 are caused by variations in tension accompanying the tensioning of the back cover 10. There are cases in which they are arranged in a meandering manner in a wavy shape without extending straight along the boundary line between them. In particular, in the case where the sewing line 14A is curved as described above, the tension associated with the tension tends to vary, and the meandering tends to be remarkable.

  Therefore, in this embodiment, the above-described cover pieces 11 and 12 are stitched together, and the stitching portion 14 exposed as the stitching line 14A is provided with rigidity capable of suppressing the meandering of the stitching line 14A. A streak-shaped core member 15 is provided by being sewn together. As shown in FIGS. 2 to 3, the core member 15 has a ball core 15 </ b> A made of a long round rod-shaped resin member and a cloth belt-like shape folded into a bag so as to wrap the ball core 15 </ b> A inside. Bag material 15B. Of the two cover pieces 11 and 12 described above, the core member 15 has a bag material 15B applied to the seam allowance 12A of the cover piece 12 covered by the upper surface of the seat back 2, and two bag materials 15B. By sewing together with the seam allowances 11A and 12A of the cover pieces 11 and 12, the inner edge 15A of the cover is provided close to the stitching portion 14, and the sewing line 14A is provided by the rigidity of the outer edge 15A. It has a structure that suppresses meandering.

  Specifically, the core member 15 is formed by the bag material 15B of the two cover pieces 11, 12 so that the rim core 15A is in close contact with the folded portion of the seam allowance 12A of the cover piece 12 covered by the upper surface of the seat back 2. The stitch margins 11A and 12A are sewn together to tightly restrain the ball edge core 15A. By providing the core member 15 in close contact with the stitching portion 14 as described above, the ball core 15A surrounds the sewing line 14A from the outer peripheral side along the shape of the sewing line 14A. Thus, it is in a state where it is provided by being bent. Since the core member 15 is provided in such a manner, the elastic restoring force of the core member 15 (the edge core 15A) acts so as to pull the sewing line 14A from the outer peripheral side in the direction in which the curve expands. become. Further, the stitching portion 14 is pressed against the core member 15 (ball core 15 </ b> A) having a curved shape with a longer circumference than the stitching portion 14 by the tension in the inner and outer directions of the curve applied between the two cover pieces 11 and 12. It becomes like this. By these actions, the stitched portion 14 does not narrow the perimeter and cause the wrinkles, but is stretched so as to widen the wrinkles toward the core member 15 (ball core 15A). Therefore, the arrangement of the core member 15 can appropriately suppress both meandering of the stitching line 14 </ b> A and wrinkles of the stitched portion 14.

  Further, in the core member 15 described above, since the ball edge core 15A is formed of a round bar-like member, the end surface of the ball edge core 15A that hits the cover piece 12 from the back side appears as a highlight on the surface of the cover piece 12. It has become difficult. Further, since the core member 15 is provided in close contact with the stitched portion 14, the core member 15 is located in the concave strip 21 of the back pad 20 where the respective stitch margins 11A, 12A of the two cover pieces 11, 12 are positioned or in the vicinity thereof. It is difficult to come out as a highlight on the surface of the cover pieces 11, 12.

  As described above, the back cover 10 (seat cover) of the present embodiment has two stitch pieces 14 that are exposed to each other by stitching the two cover pieces 11 and 12 together as a stitch line 14A. The core member 15 is provided by being sewn together with the cover pieces 11 and 12 and suppressing the meandering of the stitching line 14A by its rigidity. With such a configuration, due to the rigidity of the core member 15 that is sewn together with the two cover pieces 11, 12, the stitching line 14 </ b> A that occurs at the stitching portion 14 between the two cover pieces 11, 12. Meander can be suppressed appropriately.

  Specifically, the core member 15 has a rounded cross-sectional shape in which an end surface (the end surface of the ball core 15A) that hits one cover piece 12 from the back side is curved in the joining direction of the two cover pieces 11 and 12 ( Round bar shape). With such a configuration, the end face of the core member 15 (ball edge core 15A) is less likely to appear as a highlight on the surface of the two cover pieces 11, 12, so that the stitching line is not impaired without deteriorating the appearance. 14A meandering can be suppressed.

  The core member 15 includes a ball core 15A and a bag material 15B that encloses the ball core 15A. The bag material 15B is stitched together with the two cover pieces 11 and 12 to the stitching portion 14. Thus, the meandering of the sewing line 14A is suppressed by the rigidity of the ball edge core 15A. In this way, the core member 15 is configured to wrap the rim core 15A in the bag material 15B and sew it to the two cover pieces 11 and 12, thereby suppressing the meandering of the sewing line 14A. It is possible to provide a structure that can be appropriately sewn to the two cover pieces 11 and 12 while having the rigidity to be provided.

  Next, the configuration of the seat cover of Example 2 will be described with reference to FIGS. The seat cover of this embodiment is also configured as a cloth back cover 10 that is placed on the surface of the seat back 2 of the seat 1 of the automobile. And also in a present Example, it is the reverse U-shape of the cover piece 11 which covers the upper area | region of the side surface of the seat back 2 of the back cover 10, and the cover piece 12 which covers the peripheral area | region of the upper surface of the seat back 2. In order to suppress the meandering of the curved stitching line 14A (boundary line), the cover pieces 11 and 12 are stitched together, and the stitching line 14A meanders to the stitching portion 14 exposed as the stitching line 14A to the outside. A streak-like core member 16 having rigidity capable of suppressing the above is co-sewn.

  As shown in FIGS. 5 to 6, the core member 16 is composed of a single resin-shaped long member, and is a long thin plate-like main body piece 16 </ b> A and a short piece of the main body piece 16 </ b> A. And a round bar-shaped ball edge core 16B formed along the end in the hand direction. The core member 16 is formed with voids 16C in which the shape is perforated from the end opposite to the position where the ball core 16B is formed at various locations in the longitudinal direction of the main body piece 16A. Due to the location 16C, it is easy to bend laterally so that the entire body is greatly curved in the lateral direction. Of the two cover pieces 11 and 12 described above, the core member 16 has the main body piece 16A applied to the seam allowance 12A of the cover piece 12 covered by the upper surface of the seat back 2, and the main body piece 16A has two pieces. By sewing together with the sewing margins 11A and 12A of the cover pieces 11 and 12, the edge core 16B is provided in a state close to the stitching portion 14, and the meandering of the sewing line 14A is suppressed by the rigidity of the edge core 16B. It has a configuration.

  Specifically, the core member 16 has a main body piece 16A of the two cover pieces 11 and 12 so that the rim core 16B is in close contact with the folded portion of the seam allowance 12A of the cover piece 12 covered by the upper surface of the seat back 2. The seams 11A and 12A are sewn together. By providing the core member 16 in close contact with the stitching portion 14 as described above, the ball core 16B surrounds the sewing line 14A from the outer peripheral side along the shape of the sewing line 14A. Thus, it is in a state where it is provided by being bent. By providing the core member 16 in such a manner, the elastic restoring force of the core member 16 (ball core 16B) acts so as to pull the sewing line 14A from the outer peripheral side in the direction in which the curve expands. become. Further, the stitching portion 14 is pressed against the core member 16 (ball core 16B) having a curved shape having a longer circumference than the stitching portion 14 by the tension in the inner and outer directions of the curve applied between the two cover pieces 11 and 12. It becomes like this. By these actions, the stitched portion 14 is not stretched toward the heel by narrowing the circumferential length, but is stretched so as to spread the heel toward the core member 16 (the edge core 16B). Therefore, the arrangement of the core member 16 can appropriately suppress both meandering of the stitching line 14 </ b> A and wrinkles of the stitched portion 14.

  Further, in the above-described core member 16, since the ball edge core 16 </ b> B has a round bar shape, the end surface of the ball edge core 16 </ b> B that hits the cover piece 12 from the back side is unlikely to appear as a highlight on the surface of the cover piece 12. It has become. In addition, since the core member 16 is provided in close contact with the stitched portion 14, the core member 16 is located in or near the concave strip 21 of the back pad 20 where the seam allowances 11A and 12A of the two cover pieces 11 and 12 are positioned. It is difficult to come out as a highlight on the surface of the cover pieces 11, 12.

  Further, the core member 16 of the present embodiment has a configuration in which the main body piece 16A and the bead core 16B are integrally formed of resin, so that the main body piece 16A has a sewing allowance for the two cover pieces 11, 12. By co-sewing to 11A and 12A, the binding force associated with the stitching is performed on the core member 16 and the seam margins 11A and 12A co-sewn on the core member 16 with the ball core 16B of the core member 16 as a base point. It acts as an urging force that tilts toward the inner peripheral side of the curve of the sewing line 14A. As a result, the core member 16 and each seam allowance 11A, 12A are pressed against the surface of the back pad 20 in a state where the core member 16 and the seam allowance 11A are uniformly folded in the same direction over the entire longitudinal direction of the stitching line 14A. These back-down directions do not meander so that the back cover 10 is stretched in a more attractive manner. About the other structure, the structure shown in Example 1 is the same.

  As described above, the back cover 10 (seat cover) of the present embodiment has two stitch pieces 14 that are exposed to each other by stitching the two cover pieces 11 and 12 together as a stitch line 14A. A cover member 11 and 12 are sewn together, and a core member 16 that suppresses meandering of the stitching line 14A by its rigidity is provided. With such a configuration, due to the rigidity of the core member 16 sewn together with the two cover pieces 11, 12, the stitching line 14 </ b> A generated at the stitching portion 14 between the two cover pieces 11, 12 is formed. Meander can be suppressed appropriately.

  Specifically, the core member 16 has a rounded cross-sectional shape in which an end surface (end surface of the ball core 16B) that hits one of the cover pieces 12 from the back side is curved in the joining direction of the two cover pieces 11 and 12 ( Round bar shape). With such a configuration, the end surface of the core member 16 (ball core 16B) is less likely to appear as a highlight on the surfaces of the two cover pieces 11 and 12, so that the stitching line is not impaired. 14A meandering can be suppressed.

  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 “vehicle seat cover” of the present invention may be applied not only to automobile seats but also to seats applied to vehicles other than automobiles such as railways. It may be applied to a seat provided for a vehicle. Further, the “vehicle seat cover” of the present invention may be applied as a seat cushion cover or a headrest cover in addition to a seat back cover (back cover). Further, the “vehicle seat cover” of the present invention is applied as a cover that covers a so-called high-back type seat back in which an area portion that functions as a headrest is integrally formed in the upper area of the seat back. May be.

  The material of the seat cover may be a fabric such as a woven fabric, a knitted fabric, or a non-woven fabric, or a leather such as a natural leather or a synthetic leather. The same applies to the bag material of the core member. Further, the edge core of the core member may be made of a material other than resin as long as it has rigidity capable of suppressing the meandering of the sewing line, for example, a thick carpet material or rubber material. Good. The core member only needs to be provided along the shape of the sewing line. For example, in the case where the sewing line is curved as shown in the above embodiment, the shape of the sewing line is used. In addition to those provided by being bent along the line, those previously formed along the shape of the stitching line may be provided without being bent. In addition, the cross-section of the ball edge core is not limited to a perfect circle, it is finished in a rounded cross-sectional shape so that the end face applied to the back side of the cover piece such as an ellipse or a semicircle is not a highlight. I just need it.

  The core member of the present invention may be provided as long as it suppresses meandering of the sewing line between the two cover pieces due to its rigidity, and the sewing line as shown in the above embodiments is curved. In addition to the parts to be performed, the sewing lines may be provided in places where the sewing line is straight or bent. Further, as shown in FIGS. 1 and 4, a cover piece 13 (FIGS. 1 and 4) that covers a central region that is formed in a curved shape on the upper surface of the seat back 2 as a place where the sewing line is curved. The core member (not shown) of the present invention is applied to the stitched portion 17 of the cover piece 12 (see the same figure) covering the peripheral area of the upper surface and the meandering of these stitching lines 17A. You may make it suppress. A recess formed in a curved shape on the upper surface of the seat back 2 has a shape for receiving a headrest (not shown) mounted on the upper portion of the seat back 2, and a cover piece 13 covered with the recess. The left and right edges are curved and extend so as to rise in a tapered shape, and are sewn to adjacent cover pieces 12. Accordingly, by providing a core member (not shown) so as to be positioned on the outer peripheral side of the stitching portion 17 (sewing line 17A) at a location where the stitching line 17A is curved, the stitching portion 17 is cored. It can be in a state of being stretched so as to widen the heel toward the member, and both the meandering of the sewing line 17A and the generation of the crease at the stitching portion 17 can be appropriately suppressed.
