Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention mainly relates to a seat cover for an automobile seat, and more specifically, to the structure of a seam portion where cover materials are sewn together.

<Prior Art> Conventionally, as shown in FIGS. 8 and 9, a molded pad 3 on a seat frame 2 of an automobile seat 1 is attached to a seat cover 4 using cover materials 5 on the left and right (front and rear in some cases). Conventionally, the stitching portion 6, in which the left and right cover materials 5 are stitched together using a sewing machine or the like, has simply been formed by simply stitching the left and right cover materials 5 together with the stitches 7. The cover material 5 is made up of a pad 8 with an outer skin 9 bonded to the front side and a back base fabric 10 bonded to the back side. Further, at the same time as the cover material 5 is sewn, the hanging cloth 11 is sewn, and the wire 12 contained in the hanging cloth 11 is attached to the hog ring 1 to the mold pad insert wire 13 in the mold pad 3.
4, a predetermined tension is applied to the seat cover 4. Further, in FIG. 13, 15 is a side cover portion of the seat cover 4.

<Problems to be Solved by the Invention> In the case of the stitched portion 6 of the conventional seat cover 4 described above, the stitched left and right cover materials 5 are opened in the left and right directions in the immediate vicinity of the seam 7 in a substantially planar shape. As a result, the stitched portion 6 does not have a three-dimensional effect, resulting in poor appearance and low commercial value, that is, a lack of luxury.

Further, when a person sits on the car seat 1, the seam 7 of the seam 6 and the part near the seam 7 of the cover material 5 are permanently stretched due to tension, causing wrinkles and wrinkles in that part. There were problems in that the seat cover frayed, resulting in poor seating comfort and poor appearance, as well as impairing the durability of the seat cover.

Therefore, in view of the problems with the conventional technology described above, the purpose of the present invention is to improve the appearance, create a sense of luxury, and increase the product value by creating a three-dimensional effect in the seam part of the seat cover. An object of the present invention is to provide a seat cover that can improve sitting comfort, appearance, and durability of the seat cover by reducing local tension at the seam portion caused by sitting on the seat.

<Means for Solving the Problems> The present invention for solving the problems in the conventional techniques described above is based on the following method: with the surfaces of two cover members facing each other, the terminal portions of both cover members are made to face each other. A strip-like backing material having appropriate elasticity is provided on the back surface of at least one of the cover members to be sewn together, and the end edge of the cover member is in an open state so that the end edge of the cover member can be separated. The sheet is sewn together with the end portion as shown in FIG. It's a cover.

<Operation> According to the above-described means, the mutual cover materials are separated from the seams so that the seams formed by the sutures are hidden by the backing material provided on the mutually sewn cover materials. Since the contact surface of the cover material is held in a state where it is in contact with the surface, the contact surface portion of the cover material provides a three-dimensional effect. The loose parts of the fabric are stretched against the elasticity of the backing material, and the tension applied to the seams is reduced as much as possible.

<Example> An example of the present invention will be described below with reference to FIGS. 1 to 3. Note that this example is implemented on the seat cover 4 of the automobile seat 1 described in the section of the prior art, so the same parts are denoted by the same reference numerals, and the explanation thereof will be omitted.
Only the different configurations will be detailed.

In FIG. 1, which shows a cross-sectional view of the seam portion of the seat cover, the seam portion 6 of the cover material 5 of the automobile seat 1 is simply the left and right cover materials 5 sewn together by a seam 7. Each cover material 5
A backing material 16 is provided on the back side of the seam 7
are sutured to each other by.

The backing material 16 is made of a suitable synthetic resin material, for example, a vinyl chloride resin material, and is made of a second material.
As shown in the figure, it is formed into a band-like shape with appropriate elasticity. At the tip of this backing material 16,
A bulging portion 17 having a circular cross section is formed.

In addition, as shown in FIG. 3, the backing material 16 is
When sewing the cover material 5, the cover material 5 is placed above and below the cover material 5 so as to sandwich the upper and lower two cover materials 5 with the skins 9 facing each other, and
A hanging cloth 11 is arranged on the upper backing material 16,
In this state, by operating the sewing machine, the two cover materials 5, the backing material 16, and the hanging cloth 11 are simultaneously sewn together via the stitches 7. By opening both cover materials 5 sewn together in this way to the left and right, the cover material 5 is bent along the bulge 17 at the tip edge of the backing material 16.

In the seat cover described above, the cover material 5
The cover materials 5 are held in contact with each other up to a distance from the seam 7 so that the seam 7 is hidden by the backing material 16 sewn together with the backing material 16. The contact surface of 5 provides a three-dimensional effect, and the cover material 5
When tension is applied to the seam 7, the loose part corresponding to the contact surface of the cover material 5 is stretched against the elasticity of the backing material 16, so that the tension applied to the seam 7 is maximized. Reduced.

In addition, since the backing material 16 has a bulge 17 at its edge, it is easier to hide the seam 7 due to stitching compared to a simple band-like backing material.

Further, as shown in FIG. 4, the backing material 16
is sewn to the back surface of one (left side in the drawing) of the cover material 5, and the proximal edge of the backing material 16 is attached to the mold pad insert wire 13 of the automobile seat 1 through the attachment hole 23 provided therein. It is also possible to attach it with a hog ring 14. In addition, according to this example, the hanging cloth 11 and wire 12 in the previous example can be eliminated.

Further, as the backing material 16, as shown in FIG. 5, a hollow portion 25 is formed in the bulged portion 17, or as shown in FIG. Various shapes are possible, such as one in which elongated opening holes 29 are formed intermittently along the .

Furthermore, when the structure of the seam portion 6 of the cover material 5 as in the above embodiment is applied to the side surface of the seat cover 4, that is, the side cover portion 15, as shown in FIG. It is also possible to give special features to

<Effects of the invention> In other words, according to the invention, the stitches of the mutually sewn cover materials are hidden by the backing material provided on the mutually sewn cover materials. Since the cover material is held in contact with the seat even at a distance from the cover material, the contact surface of the cover material has a three-dimensional effect, which improves the appearance, creates a sense of luxury, and increases the product value of the seat.

In addition, when tension is applied to the cover material due to someone sitting on it, etc., the loose part of the cover material corresponding to the contact surface is stretched against the elasticity of the backing material, and the tension is applied to the seam. Since the tension is reduced as much as possible, wrinkles and fraying caused by sitting can be prevented as much as possible, and the sitting comfort, appearance, and durability of the seat cover are improved.

In addition, since the backing material is sewn together with the cover member in an open state where the end edge of the cover member can be separated, it is possible to create a design that fits the outline of the sheet, where most of the surfaces are three-dimensional. . To explain this point in detail, for example, as shown in Japanese Unexamined Patent Publication No. 154692/1983, a backing material having a substantially U-shaped cross section is fitted into the part where the cover member is folded in half. If the seat cover is sewn in a closed state, the folded portion of the cover member will be restrained by the backing material, making it difficult for the seat cover to conform to the three-dimensional surface of the seat. However, the present invention solves this problem. Problems like this will be improved.

In addition, since the backing material has a bulge on its edge that is located on the base fabric side of the cover member and has a nearly circular cross section, the contact surface of the cover material has an elasticity compared to a simple band-like backing material. By effectively holding the cover material in place, the seams can be easily hidden, and the three-dimensional appearance of the contacting surface of the cover material can be further improved.
