Description

  The present invention relates to a skin of an automobile seat (seat), and more particularly to a skin having a bead along a joining portion of two skin materials.

  In order to improve the appearance quality of the sheet, there is a sheet in which a decorative bead is sandwiched along the joining portion of the outer skin constituting the outer surface of the sheet.

  The above-described ball edges are formed by sewing a string-shaped ball core between the outer skin materials that join the covering materials by interposing the center of the tape-shaped covering material in the width direction.

  Therefore, since the seam allowance of the joined skin material and covering material is on the inside, when the foam pad is covered with the joined skin with the rim, the seam allowance will meander, and this meandering causes the surface of the sheet to The rim that protrudes in the meander also meanders.

  In particular, when the bead is in a curved portion of the sheet, the bead of the bead is severe, and the appearance quality of the sheet is impaired.

  In order to eliminate such a problem, for example, as disclosed in Japanese Patent Application Laid-Open No. 57-166774, there is one in which the entire bead is sewn integrally to the outer surface of the skin.

Japanese Unexamined Patent Publication No. 57-166774

  As described above, in the case where the ball edge is integrally sewn on the outer surface of the skin, the ball edge protrudes from the outer surface of the skin, so that the ball edge becomes a foreign object feeling when seated.

  Moreover, there was a possibility that the ball edge may be peeled off from the skin by long-term use of the sheet.

  Therefore, an object of the present invention is to eliminate the problems of such conventional products.

  In order to achieve the above object, the present invention provides a skin of a sheet having a bead along the joining portion of the skin material A and the skin material B, wherein the bead wraps the ball core and the ball core. And the ball core is sewn together between the skin material A and the skin B together with the coating material, and the coating material includes a head that covers the ball core, and left and right sides of the head. The leg portions are configured to be integrally sewn inside the skin material A and the skin material B together with a seam allowance folded back inside the skin material A and the skin material B.

  With the above configuration, the ball core and the covering material constituting the edge are sewn integrally to the skin materials A and B, and each seam allowance of the skin materials A and B and the covering material is integrated inside the skin materials A and B. Sewn.

  According to the present invention, since the bead is sewn integrally along the joining portion of the skin materials A and B, the bead is not peeled off from the skin even when the sheet is used for a long time.

  Further, since the seam allowances of the skin materials A and B and the leg portions of the covering material are integrally sewn inside the skin materials A and B, the bead does not meander like the conventional products.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a state in which the ball edge (4) is sewn along the joining portion between the skin material A (1) and the skin material B (2).

  The skin material A (1) and the skin material B (2) are used for conventional trim covers for automobile seats, and have a multi-layer structure having a wadding and wadding cover on the back surface, or a single layer such as leather. Of structure.

    The ball edge (4) shown in FIGS. 3 and 4 is composed of a ball core (3) and a covering material (4A) covering the ball core (3), and the ball core (3) has a hardness through which a sewing needle passes. The cord (4A) is a tape-like cloth or the like, preferably a resin cord having flexibility, and the outer surface is colored differently from the skin material A (1) and the skin material B (2). Are using things.

  The above ball core (3) is sandwiched in the center in the width direction of the covering material (4A) as shown in FIG. 1, and the covering material (4) is bent in a U shape with the ball core (3) inside. Cover the ball core (3).

  The portion covering the ball core (3) of the coating material (4A) is defined as the head portion (40), and the head portion (40) and the ball core (3) are connected to the skin material A (1) and the skin material B ( 2) Put it in the terminal and sew the sewing machine with the sewing thread (5).

  Accordingly, the surface of the ball core 3 corresponding to the skin material A (1) and the skin material B (2) is cut into a substantially flat shape so that the center of the ball core (3) can be sewn with a sewing machine. It is formed in a circle.

  The above sewing thread (5) is sewn with the terminals (1A) and (1B) of the skin material A (1) and the skin material B (2) and both terminals (41A) and (42A) of the covering material (4A). To align.

  Accordingly, the space between the sewing thread (5) and the terminals (1A) and (2A) is the seam allowances (10) and (20) of the skin material A (1) and the skin material B (2), and both ends of the covering material (4A). The portions from (41A) (42A) to the sewing thread (5) are defined as the leg portions (41) (42) of the covering material (4A).

  Next, the seam allowances (10) and (20) of the skin material A (1) and the skin material B (2) are bent inward, respectively, and the leg of the covering material (4A) is added to the seam allowances (10) and (20). The parts (41) and (42) are bent in an open leg shape so as to be outside the seam allowances (10) and (20), and these are simultaneously, that is, double-stitched, so that the skin material A (1) and the skin material B By sewing (2) with the sewing threads (51) and (51), as shown in FIG. 2, the skin with the bead (4) is sewn.

  The double stitch sewing with the above-described sewing threads (51) (51) is performed with the ball core (3) as the center.

  FIG. 3 shows an automobile seat having a bead (4)..., For example, as shown in FIG. 4, the bead (4) is along a corner of a foam pad (6) constituting the sheet. The appearance quality of the sheet is improved.

  As described above, the coating material (4A) is colored differently from the coloring of the outer surfaces of the skin material A (1) and the skin material B (2), so that the coating material (4A) becomes a border pattern and the appearance quality of the sheet Will be improved.

  Further, the seam allowances (10) and (20) of the skin material A (1) and the skin material B (2) and both legs (41) and (42) of the covering material (4A) are the skin material A (1) and the skin material. Since it is sewn integrally on the back side of B (2), the edge of the ball does not meander due to meandering of the seam allowance unlike the conventional product.

  Further, since the bead (4) provided between the skin material A (1) and the skin material B (2) does not protrude from the outer surface of the skin as in the conventional product, the bead (4) is a foreign object. There is no feeling.
