Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a sheet skin which is applied to form a predetermined edging shape at a stitching point of a skin material when sewing a plurality of skin materials cut into a predetermined shape into a predetermined three-dimensional shape. Related to the edging structure of.

[0002]

[Prior Art]

 Conventionally, when a plurality of skin materials are sewn together between terminals to form a seat skin in a three-dimensional sewn shape, a ball portion is exposed at a position where the skin material is sewn and a strip plate portion is used as the skin material By sandwiching it between them and sewing this strip together with the end of the skin material, the rim is sewn along the stitching point of the skin material.

The bead is attached so that the stitched portion of the skin material is hidden by the bead portion, and the stitched portion of the skin material is held by the strip portion. However, since this bead is sewn with the strip part sandwiched between the ends of the skin material, the shape of the sewn part must depend on the stitch line. However, in this case, there is a risk that the shape of the portion to be sewn may vary depending on the sewing technique.

[0004]

[Problems to be solved by the device]

 It is an object of the present invention to provide an improved edging structure for a seat skin, which is capable of forming a desired stitched portion of the skin material regardless of the sewing technique.

[0005]

[Means for Solving the Problems]

 In the edging structure of the seat skin according to the present invention, a thin axial core material is wound inside the desired position of the skin material and wound around the end of the skin material and co-sewn with the end of the skin material, and the skin material is wound. The edge of the material is formed into a predetermined edging shape along the axis of the core material.

[0006]

[Action]

 In this edging structure of the skin of the seat, a narrow axial core material is wound inside the desired stitching portion of the skin material and sewn together with the end of the skin material, and the core material is formed in the axial shape of the core material. Since the edges of the skin material to be rolled up are shaped, it is possible to form the sewn portion of the skin material in a desired edging shape as desired without resorting to skilled sewing techniques.

[0007]

【Example】

 Hereinafter, referring to the accompanying drawings, FIG. 1 is a partial cross-sectional view showing a seat skin 1 sewn into a three-dimensional shape and attached to a cushion pad P. The sheet skin 1 is formed in a three-dimensional bag shape by sewing a plurality of skin materials 1a, 1b ... When this terminal is sewn, the narrow shaft-shaped core material 2 is wound inside the sewn portion at the desired position and sewn together.

As the narrow axial core material 2, a plastic bead composed of a ball portion 2a and a band plate portion 2b is used. The core material 2 is formed so as to have a predetermined axial shape corresponding to a desired stitching point of the skin material. As the axial line shape, it is possible to form a curved line or a straight line at a portion to be shaped such as a gate shape as shown in FIG. The core material 2 is attached so as to be wound inside the skin material 1a by sewing the strip plate portion 2b together with the skin materials 1a and 1b.

For example, in the case of using the above-mentioned gate-shaped core material 2, as shown in FIG. 3, in the seat back B of the automobile seat, the edging line 3 corresponding to the contour shape of the backboard is attached to the seat skin 1. It can be formed at the time of sewing. In order to form the edging line 3, the skin material 1a cut as a back support and the skin material 1b cut in a backless shape are turned upside down and the terminals are overlapped, and the ball portion 2a is formed at the end of the skin material 1a. After arranging the core member 2 further inward and assembling the core member 2 along the inner side of the end of the skin material 1a, the band plate portion 2b may be sewn together with the ends of the skin materials 1a and 1b. Instead of the above-mentioned bead, a trim member having a substantially U-shaped cross section or a U-shape as shown in FIG. 4 can also be used as the core material 2.

By covering the cushion pad with the seat surface 1, it is possible to form a backboard-like edging line 3 formed by the core material 2 on the back side of the seat back B. Since the edging line 3 is shaped in the axial shape of the core material 2, it can be formed in a predetermined shape. Further, the seat cover 1 is attached with a step h which is higher than the general surface of the cover 1a formed by the cover 1b by the diameter of the ball 2a. According to this edging line 3, the backboard can be omitted to be attached to the seat back B because the back side of the seat back B can have a sharpness and a texture to give a high-class feeling. Further, since the stitching points of the skin materials 1a and 1b including the core material 2 are located closer to the inner side of the core material 2, the stitch line is not exposed to the outside.

Although the above-described embodiment has been described in the case where the backboard-shaped edging line 3 is formed on the back side of the seat back B, in addition to this case, as shown in FIGS. It can also be applied to a stepped piece h provided on the lower side so as to have an appearance like a sitting hood. Further, the present invention can be widely applied to shape the contour shape of each portion of the seat including the shape of the shoulder portion of the seat back being linear.

When the core material 2 is sewn together with the skin materials 1a and 1b, it can be pre-sewn to either of the skin materials 1a and 1b in advance as shown in FIG. When the beaded core material 2 is used, the skin material 1a can be further sewn to the strip plate portion 2b of the core material 2 along the inner edge of the core material 2 as shown in FIG. The edging structure not only prevents the core material 2 from being inverted, but also encloses the bead 2a of the core material 2 with the skin material 1a, so that the edging line can be clearly drawn and the ring shape of each part of the seat is formed. Can be beautifully shaped.

[0013]

As described above, according to the edging structure of the seat skin according to the present invention, the stitching portion of the skin material is formed by the core material of the predetermined axial shape to be sewn together, so that the skilled sewing The edging line can be shaped as desired without resorting to techniques.
