Description

  The present invention relates to a covering skin material that is coated on a base material of a vehicle interior member such as a lid for an accessory case or an armrest, and more specifically, a coating that prevents the occurrence of wrinkles at the corners of the base material. It relates to a skin material.

  Generally, a cover body such as a floor console, which is an interior member of an automobile, an armrest, and the like are made of a synthetic resin base material covered with a skin material. As the skin material, soft synthetic resin molded products, woven fabrics, leathers and the like are used. The cover material made of woven fabric or leather is covered with a base material made of a rigid body, and then the excess end part is drawn inside the base material, temporarily fixed, and fixed with a tucker or the like. There is something that is. In addition, there is a material in which a plurality of skin pieces are sewn and a skin material formed along the outer surface shape of the base material is coated on the base material, and an excessive end portion thereof is drawn into the base material and fixed.

  In recent years, several skin pieces made of leather are joined together by sewing to form a skin material, and the seam allowance is brought close to one skin piece to form a superposed part, and the superposed part is sewn by a single stitch. Yes. This single stitch is the decorative stitch required by the designer. A problem that occurs when the base material is coated with such a skin material and an action that causes the problem will be described with reference to FIGS.

  As shown in FIG. 6, a polyurethane foam pad 64 is attached to the outer surface of a hollow base 65 made of synthetic resin, which is a blow molded product. In the skin material, a main skin piece 61 and a side skin piece 62 made of leather are joined together by sewing at a joining portion 63, and a decorative stitch 60 is formed at a superposed portion of a seam allowance for the joining. The skin material covers the base material 65 through the pad 64. Further, an inner 80 made of synthetic resin is disposed so as to cover the inside of the base material 65, and is fixed to the base material 65 at a mounting portion (not shown). A plurality of ridges 70 appear on the left and right of the decorative stitch 60.

  As shown in FIG. 7, the covering operation of the skin material on the base material 65 is performed by placing the base material 65 with the pad 64 attached to the inside of the skin material, then the main skin piece 61, the superposition part 61 a, This is performed while the portion 62a and the side skin pieces 62 are sequentially drawn inward. FIG. 8 shows a state in which the end portion of the skin material is fixed by the tucker 71.

  As shown in FIG. 8, since the triple overlapping part composed of a part of the main skin piece 61, the overlapping part 61a and the overlapping part 62a is reinforced by the decorative stitch 60, the overlapping part made of leather which is a material that is difficult to stretch Hardly grows. Therefore, it becomes difficult to eliminate the plurality of wrinkles 70 appearing on the left and right of the overlapped portion by stretching the main skin piece 61 and the side cover pieces 62 including the overlapped portion.

  As described above, when the skin material is drawn inside the base material, the operation of drawing the skin material while stretching the skin material so as not to cause wrinkles at the corners of the base material requires skill and increases man-hours. .

  The “armrest manufacturing method” disclosed in Patent Document 1 is a skin-like material covered with a synthetic resin base material having corner portions at the front and rear ends, and the portions corresponding to the corner portions are bag-shaped sewing portions. The portion corresponding to the curved portion is a shearing sewing portion. For this reason, when covering a base material with a base material, it can coat | cover, extend temporarily the rubber string of a shirring sewing part, and can fix now. Therefore, it is said that there is an effect that the skin material can be easily and accurately attached to the base material without skill, and that the peripheral portion of the armrest has no wrinkles and has an excellent appearance.

JP 2004-129743 A (see [Summary] [Effects of the Invention])

  However, the skin material disclosed in Patent Document 1 is a sheet-like body unlike a skin material in which a plurality of skin pieces are joined by sewing. Moreover, the inner of the plate-shaped body which covers the back side of a base material is not used, but it attaches to the structural member in a vehicle interior as it is. Then, a gap is created between the inner edge and the skin material due to the difference in thickness between the overlapping part where the seam allowance for joining the skin pieces is superposed and the part where there is no overlapping part and only the skin piece is present. The problem of poor appearance cannot occur. Further, for example, when a plurality of leather skin pieces, which are difficult to stretch, are joined together by sewing and the joined skin materials are coated on a base material, even if the overlap portion of the seam allowance is pulled in, there is almost no elongation. Therefore, there is a problem that it is difficult to stretch the wrinkles that can be formed on the left and right sides of the overlapping portion. As described above, it is difficult to adopt the technique disclosed in Patent Document 1 as a means for solving the problem that wrinkles that are deep in the periphery of the overlapped portion are likely to occur at the corners of the base material, and that poor appearance is likely to occur.

  The present invention has been made paying attention to such problems, the purpose of which is to prevent the skin material covering the base material from becoming wrinkles at the corners of the base material, An object of the present invention is to provide a covering skin material that prevents a gap from being generated between the skin material drawn inside the base material and the inner end portion covering the inside of the base material.

  In order to solve the above-mentioned problem, the covering skin material according to claim 1 is a covering skin material in which a plurality of skin pieces are joined by sewing, and the outer skin material is outside the seam of the two skin pieces. In the covering skin material in which the end portion is folded to one side of the skin piece to form the overlapped portion, a decorative stitch is formed in the overlapped portion and the end portion of the box-shaped base material is covered. The width of the overlapping portion is narrowed from the portion to the inside of the base material with the reduced width portion as a boundary.

  According to the first aspect of the present invention, the overlapping portions are formed by folding the respective end portions outside the stitches connecting the two skin pieces to one skin piece side, The decorative stitch was formed, and the width of the overlapped portion was narrowed at the reduced width portion from the portion covering the end of the box-shaped substrate to the portion drawn into the substrate. Therefore, it becomes easy to pull and stretch the overlapped portion having a narrow width, and generation of wrinkles in the portion around the overlapped portion of the skin material can be prevented. Further, since the stretched overlapped portion becomes thin, the step between the skin where the overlapped portion is not formed and the overlapped portion becomes small. Therefore, when the end of the inner that is in close contact with the skin material presses the stepped portion, generation of a gap in that portion is prevented.

  According to a second aspect of the present invention, in the covering skin material according to the first aspect, the decorative stitch formed in the overlapped portion is reduced in width in the outer skin piece through the reduced width portion. It is characterized by being provided continuously in the outer part of the overlapping portion.

  According to the second aspect of the present invention, the decorative stitch formed in the overlapping portion is formed by extending the outer skin piece of the overlapping portion whose width is reduced. Therefore, decorative stitches are continuously formed on the surface of the skin material, and a design effect is exhibited. Moreover, in the skin material drawn into the inside of the base material, decorative stitches are formed at portions where the overlapped portion is removed. Accordingly, it is easy to stretch the overlapped portion that is not reinforced by the decorative stitch, and it is possible to prevent the occurrence of wrinkles in the skin material on both sides of the overlapped portion.

  The invention according to claim 3 is the covering material according to claim 1 or 2, wherein the overlapping portion is stitched by the decorative stitches arranged in a row to cover the outer surface portion of the substrate. It is characterized by being buried in a body pad.

  According to the third aspect of the present invention, since the superposed portion whose end portion is superposed on the skin piece is buried in the foam pad that covers the outer surface portion of the base material, polymerization is performed on the surface of the skin material. It is possible to prevent the formation of a protruding ridge that is raised by the portion. Therefore, it becomes possible to form a superposition part on one skin piece, and it is possible to provide a design in which only one row of decorative stitches for stitching the superposition part is formed without a sense of incongruity due to the protrusion. .

  The invention according to claim 4 is the covering skin material according to any one of claims 1 to 3, wherein the surface of the skin piece is formed of a leather sheet. Is.

  According to the fourth aspect of the present invention, the surface of the skin piece is formed of a leather sheet that is a material that does not easily stretch, and the decorative stitches are formed in the superposed portion to give a high-class feeling. And since the width | variety of the superposition | polymerization part is narrowed in the part drawn in to the inner side of a base material, even if it is a leather which is hard to stretch, the elongation for preventing generation | occurrence | production of a wrinkle is possible.

  According to a fifth aspect of the present invention, in the covering skin material according to any one of the first to fourth aspects, the base material is used for a vehicle interior member provided with an inner covering the inner side of the base material. It is characterized by covering.

  According to the invention described in claim 5, in the vehicle interior member provided with the inner covering the inside of the base material, the covering skin material of the present invention covers the base material. Therefore, it is possible to prevent the appearance from being deteriorated due to a gap between the inner and the skin material.

  According to the present invention, the decorative stitches are formed in the overlapped portion where the outer ends of the seams of the two skin pieces are folded to one side of the skin pieces, and are drawn into the box-shaped base material. The width of the overlapped portion of the portion to be covered is narrowed, so that the step between the overlapped portion and the adjacent skin material is reduced, and a covering skin material having a decorative stitch that allows the elongation of the overlapped portion is provided.

(Embodiment)
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments embodying the present invention will be described with reference to FIGS. In addition, about the same structure as a prior art, the same code | symbol used in the description shall be used.

  As shown in FIG. 1, in the skin material 2 of the present embodiment, a main skin piece 11 and side skin pieces 12 arranged on the left and right sides are joined at a joining portion 63 to form a flat rectangular parallelepiped box shape. The armrest 1 is formed by being covered with a base material that is not to be covered. A row of decorative stitches 10 is formed inside each of the left and right connecting portions 63 to create an excellent design. The armrest 1 also serves as a lid that is supported as a vehicle interior member so as to be opened and closed by a floor console used as an accessory case (not shown).

  As shown in FIG. 2, the main skin piece 11 and the side skin pieces 12 are sewn and joined by a seam 63a. The end portion outside the seam 63a of the main skin piece 11 is folded back to form a superposed portion 11a, and the end portion outside the seam 63a of the side skin piece 12 is folded toward the main skin piece 11 side. As a result, the superposed portion 12a is formed. The overlapping portion 11 a and the overlapping portion 12 a are stitched together with the main skin pieces 11 by the decorative stitch 10. The main skin piece 11 and the side skin pieces 12 of the present embodiment are a three-layered laminate composed of a leather sheet, a polyurethane foam sheet, and a cloth-like tricot.

  And this skin material 2 is covered via pad 64 on outer surface part 65c of base material 65 to which pad 64, which is a polyurethane foam molded product, is adhered, and is folded back at end part 65a to be inside base material 65. The end portion 12d is pulled in and fixed to the inner surface portion 65d by a tacker (not shown). The end portion of the main skin piece 11 is similarly fixed to the inner surface portion 65d by a tacker. In this way, since the skin material 2 is applied to the base material 65 via the pad 64 in a tensile state, the overlapping portion 12a and the overlapping portion 11a are buried in the pad 64. Accordingly, it is possible to prevent the protrusions from being formed along the decorative stitch 10.

  Further, the end portion 80a of the inner 80 engaged with the engaged portion (not shown) of the base material 65 is in close contact with the portion of the skin material 2 near the folded portion 12c. The inner 80 is provided so that the inner side of the base material 65 is not exposed when the armrest 1 is opened, and a recess as a cup holder may be formed. The base material 65 of the present embodiment is a box-shaped PP (polypropylene) resin blow-molded product having a hollow bottom portion and side portions. For this reason, it is easy to tacker the end portion 12d of the skin material 2 to the base material 65.

  Next, the skin material 2 of the present embodiment in which the width of the overlapping portion where the end portion outside the seam 63a is overlapped is reduced with the reduced width portion 13 as a boundary will be described with reference to FIGS. . FIG. 3 is a plan view of the skin material 2 viewed from the back side.

  As shown in FIG. 4 (b), the portion indicated by the arrow CC in FIG. 3 has a three-layer overlapping portion composed of the main skin piece 11, the overlapping portion 11a, and the overlapping portion 12a stitched by stitch yarn 10a. . The three-layer overlapped portion is narrowed through the reduced width portion 13 from the base point 13a to the intermediate point 13b, and is kept constant from the intermediate point 13b to the end point 14. The reduced width portion 13 is disposed so as to be positioned at the end portion 65 a when the skin material 2 is covered with the base material 65.

  As shown in FIGS. 3 and 4A, the decorative stitch 10 is formed continuously from the reduced width portion 13 to the end portion 11c of the main skin piece 11, but the reduced width portion 13 is formed. And the end portion 11c, only the main skin piece 11 is formed by the stitch yarn 10a outside the narrow overlap portion 11b and the narrow overlap portion 12b. Accordingly, the overlapping portion composed of the main skin piece 11 from the intermediate point 13b to the end point 14, and the narrowed overlapped portion 11b and the narrowed overlapped portion 12b restrains each other than the seam 63a. Since there is nothing, it becomes possible to extend from the overlapping portion where the decorative stitch 10 is formed.

  A part of the process of covering the base material 65 with the skin material 2 in which the width of the overlapping portion is narrowed between the reduced width portion 13 and the end portion 11c will be described with reference to FIG. FIG. 5 shows a state in which the base material 65 having the pad 64 attached to the inside of the skin material 2 is set. In this state, when the main portion skin piece 11, the reduced overlapped portion, and the side portion skin piece 12 are drawn toward the inner surface portion 65d while being pulled upward in the figure, the reduced width portion 13 is not at the end. The overlapped portion which is located at the portion 65a and is reduced in width is stretched. Then, in the main skin pieces 11 and the side skin pieces 12 on both sides of the reduced overlapped portion, the wrinkles having deep grooves that appear unless they are stretched are stretched. As shown in FIG. 8, by fixing the end portion of the skin material 2 in a state where no unsightly wrinkles are generated to the base material 65 as shown in FIG. Can be prevented.

  Further, since the reduced overlapped portion is stretched to reduce its thickness, when it is brought into close contact with the end 80a of the inner 80, the overlapped portion and the left and right main skin pieces 11 and side skin pieces 12 It is possible to prevent a level difference from appearing between the two.

Therefore, according to the above embodiment, the following effects can be obtained.
(1) In the above-described embodiment, the overlapping portions are formed by folding the respective outer ends of the seam 63a that joins the main skin pieces 11 and the side skin pieces 12 to the main skin pieces 11 side. Then, decorative stitches 10 were formed in the overlapped portion. And the width | variety of the superposition | polymerization part between the reduced width part 13 located in the part which coat | covers the edge part 65a of the base material 65 to the edge part 11c of the main part skin piece 11 was made narrow. Therefore, it becomes easy to pull and stretch the overlapped portion having a narrow width, and generation of wrinkles in the portion around the overlapped portion of the skin material 2 can be prevented in advance. Further, since the stretched overlapped portion becomes thin, the step between the main skin piece 11 and the side skin piece 12 where the overlap portion is not formed and the overlapped portion becomes small. Accordingly, when the end portion 80a of the inner 80 is in close contact with the skin material 2 adhered to the base material 65, it is possible to prevent the step portion from being pressed and a gap being generated therein.

  (2) In the above embodiment, the decorative stitch 10 formed in the overlap portion is extended from the reduced width portion 13 to the end portion 11c of the main skin piece 11, and the narrow overlap portion 11b and the narrow overlap portion 12b. The outer main skin piece 11 was formed. Therefore, the decorative stitch 10 is continuously formed on the surface of the skin material 2 to exhibit a design effect. Moreover, in the skin material 2 drawn inside the base material 65, the decorative stitch 10 is formed in the portion where the overlapped portion is removed, so that it is easy to stretch the overlapped portion that is not reinforced by the decorative stitch 10. Therefore, generation | occurrence | production of the wrinkles which have the deep groove | channel in the main part skin piece 11 and the side part skin piece 12 of the both sides of a superposition | polymerization part can be prevented beforehand.

  (3) In the above-described embodiment, the overlapping portion 11 a and the overlapping portion 12 a whose end portions are polymerized on the main skin piece 11 are buried in the pad 64 attached to the base material 65. Therefore, it is possible to prevent the formation of the protruding portion that rises due to the overlapping portion on the surface of the skin material 2. Therefore, it is possible to superimpose the superposed part 11a and the superposed part 12a on the main skin piece 11, and it is possible to provide an excellent design in which only one row of decorative stitches 10 for stitching the superposed part is formed.

  (4) In the said embodiment, the main part skin piece 11 and the side part skin piece 12 were made into the three-layer laminated body which consists of a leather-made sheet | seat, a polyurethane foam sheet | seat, and a cloth-like tricot. Then, a superposed portion obtained by superposing the respective outer ends of the seam 63 a that joined the main skin piece 11 and the side skin piece 12 was stitched by the decorative stitch 10. Therefore, the decorative stitch 10 gives a higher-class feeling to the main skin piece 11 made of leather. Moreover, since the width of the overlapped portion is narrowed at the portion drawn inside the base material 65, even if it is leather that is difficult to stretch, the elongation to prevent the generation of wrinkles having deep grooves is not possible. can get. Therefore, it is possible to provide a skin material for clothing in which the appearance of wrinkles with a poor appearance is prevented in spite of being the main skin piece 11 made of leather.

  (5) In the above embodiment, the inner side of the lid that is supported by the floor console as an accessory case so as to be opened and closed and also serves as an armrest is covered with the inner 80. Therefore, it is possible to provide a covering skin material in which when the lid is opened, a gap is generated between the inner 80 and the skin material 2 to prevent the appearance from being deteriorated.
