Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a skin member of a seat cushion.
Specifically, the present invention relates to an improvement in the suture structure of the skin that covers the front surface of the seat cushion from the upper surface of the seat cushion.

(Prior Art and its Problems) Conventional skin members of seat cushions include those shown in FIGS. 5 to 7.

In such a conventional product, the upper surface skin 2' that covers the upper surface 1'a of the seat cushion 1' is formed of a left part 2'a and a right part 2'b, and the left part 2'a and the right part 2''b
The two are sewn together to form a single body. Further, the front surface skin 3' that covers the front surface 1'b of this seat cushion 1' is formed from a left part 3'a and a right part 3'b. suture.

Further, the front surface skin 3' and the upper surface skin 2' are sewn together to cover the front surface 1'b from the upper surface 1'a of the seat cushion 1'.

The upper skin 2' has a left part 2'a and a right part 2'b having the same shape, and the left part 2'a and right part 2'b are sewn together to form an upper surface 1' of the seat cushion 1'. It covered a.

However, since there is not enough room in the depth direction of the upper skin 2', the tip 4' of the suture line where the left part 2'a and the right part 2'b are sewn is connected to the front surface 1'b of the seat cushion 1'. I couldn't bring it down.

When the leading end 4' of the suture line was pulled down, the suture line 5' between the left part 2'a and the right part 2'b became meandering and wrinkled.

Therefore, when the suture line tip 4' can be pulled down to the front surface 1'b of the seat cushion 1', the suture line 5' between the left part 2'a and the right part 2'b is suspended. Therefore, the appearance quality is improved, but the conventional product cannot do this and has a problem of deteriorating the appearance quality.

The present invention was devised in view of this point, and allows the tip of the suture line of the upper surface skin covering the upper surface of the seat cushion to be pulled down to the front surface of the seat cushion. To provide a skin member of a seat cushion that can form a deep concave line in the center.

(Means for solving the problem) The skin member of the seat cushion according to the present invention is
A skin member for a seat cushion having an upper surface skin consisting of a left part and a right part covering the upper surface of the seat cushion, and a front skin comprising a left part and a right part covering the front surface of the seat cushion, wherein the upper surface A notch is formed in the same circular shape on the sides of the center of the left and right parts of the epidermis, and the sides of the center of the right and left parts are sewn together.

(Function) According to the skin member of the seat cushion having the above structure, the seam line between the left and right parts of the upper surface skin forms a notch, so the seam line is longer than before. The tip of the suture line is pulled down from the top surface of the seat cushion to the front surface of the seat cushion, forming a concave line from the top surface to the front surface of the seat cushion.

(Embodiment) An embodiment of the present invention will be described based on FIGS. 1 to 4. In the figure, seat cushion 1
The foam pad 2 is covered with a skin member 3.

This skin member 3 includes an upper surface skin 4 that covers the seat cushion upper surface 1a and a seat cushion front surface 1b.
It is formed with a front skin 5 covering the.

The upper surface skin 4 consists of a left part 4a and a right part 4b, and is formed by sewing these left part 4a and right part 4b together.

The left part 4a and the right part 4b of the upper surface skin 4 have the same shape, and as shown in FIG.
Notches 7 and 8 are provided on the sides 5 and 6 on the center side of b.

These notches 7 and 8 are formed on the upper surface 1 of the seat cushion.
It is formed in front of a and is cut out in a substantially elliptical shape.

As shown in FIG. 4, the left part 4a and the right part 4b are overlapped with each other, and the sides 5, 6 and the notches 7, 8 on the center side are sewn together.

Furthermore, the tip side 9 of this upper surface skin 4 and the front surface skin 5
When the upper end side 10 of the foam pad 2 is sewn together and the foam pad 2 is covered, the seat cushion is covered from the upper surface 1a of the seat cushion along the front surface 1b of the seat cushion.

Since the suture line 11 between the left part 4a and the right part 4b of the upper surface skin 4 is curved, it is longer than when the straight sides are sutured.

Therefore, since the suture line 11 of the upper skin 4 becomes longer as described above, its tip 11a is located on the front surface 1b of the seat cushion as shown in FIG. A margin is created in the covering of the skin 4, a deep concave line can be formed at the boundary between the left part 4a and the right part 4b, and the appearance quality is improved.

Further, when the upper surface skin 4 is covered, the suture line 11 has a margin corresponding to the length thereof, so that the suture line 11 does not meander or wrinkle, and becomes straight.

In addition, in the above embodiment, a case was explained in which semi-elliptical notches were formed on the left and right parts of the upper surface skin, but the notches are not limited to a semi-elliptical shape, but may have a circular shape, for example. It may be.

(Effects of the invention) According to the invention, since it is configured as described above, the following effects are achieved.

Since substantially semicircular notches are formed in the left and right parts of the upper surface skin, the suture line between these left and right parts is longer than the conventional straight suture line. Therefore, the tip of the suture line can be located on the front surface of the seat cushion, and a deep concave line can be formed at the boundary between the left and right parts.

Therefore, the appearance quality of the seat cushion is improved.

Since the suture line between the left and right parts of the upper skin is long, this suture line becomes straight when the upper skin is covered.

Therefore, the suture line does not meander or wrinkle as in the conventional case.
