Description

[Detailed description of the invention] [Industrial field of application] This invention relates to the original fabric used to obtain the cover pieces constituting the vehicle seat cover, and is particularly concerned with the work efficiency when sewing the cover pieces cut from the original fabric. This invention relates to a raw fabric for vehicle seat covers that can improve the properties of vehicle seat covers.

[Conventional technology]

2. Description of the Related Art Conventional vehicle seat covers are known in which, for example, a skin made of non-breathable vinyl chloride or the like and a wadding made of slab urethane or the like are laminated together. Such a seat cover is designed to obtain a predetermined sheet shape by sewing together a plurality of cover pieces having a predetermined shape obtained by cutting an original fabric. That is, in this sewing operation, the edges of each cover piece are overlapped so that the outer skins are in contact with each other, and the overlapping portion (hereinafter referred to as the sewing portion) is sewn together using a sewing machine. In addition, the seat cover formed in this way, for example, in the case of an integrally formed skin sheet, is placed in a mold for molding the seat pad, and a foamable synthetic resin for the seat pad is injected into the mold. This allows the seat pad and seat cover to be integrated at the same time as the seat pad is molded.

[The problem that the idea attempts to solve]

By the way, when sewing such a seat cover with a sewing machine, as mentioned above, place the sewn part of the cover piece on the bed of the sewing machine, and sew it using the throat plate on the bed side and the presser piece on the sewing needle side. The sewing needle is operated while the sewing machine is pressed down, and the sewing operation progresses while gradually sliding the sewing section.

However, in conventional vehicle seat covers, the foamed wading comes into direct contact with the needle plate and presser foot of the sewing machine during this sewing process, and the friction coefficient of the wading surface is high, causing damage between the two. There was a problem in that large frictional resistance was generated, the sewing part did not slide easily, and workability was poor.

This invention provides a raw material for a vehicle seat cover that allows the sewing part of the cover piece to easily slide against the sewing machine when sewing the cover piece, thereby improving work efficiency. The purpose is to

[Means to solve the problem]

In order to achieve the above object, this invention forms a coating portion on the surface of the wadding in a raw material for a vehicle seat cover which is formed by sewing together a plurality of cover pieces each having wadding arranged on the back side of the outer skin. .

[Effect]

With the above configuration, the coating portion is located on the wadding surface of the cover piece formed by cutting the original fabric. Therefore, when sewing this cover piece, the throat plate or presser foot of the sewing machine comes into contact with the wading through the coating part, reducing the frictional resistance between the two and making it easier to slide the sewing part. .

〔Example〕

Hereinafter, embodiments of this invention will be described in detail using the drawings.

FIG. 1 is a perspective view showing the appearance of a vehicle seat 2 provided with a vehicle seat cover 1 formed from a raw fabric according to this embodiment, and FIG. 2 is a schematic cross-sectional view of the vehicle seat 2.

This vehicle seat 2 is configured as a front seat, and a seat back 2B is arranged at the rear end of the seat cushion 2A. Further, a headrest 2C is provided on the upper part of the seat bag 2B.

Seat cushion 2A and seat back 2B
In this example, seat pads 4A and 4B are arranged on seat frames 3A and 3B, respectively, and seat covers 1A and 1B are attached to the outer circumferences of these pads.

Each seat cover 1A, 1B is constructed by sewing four cover pieces 1a to 1d and 1e to 1h to each other to form a seat cushion 2 as shown in the figure.
A or a shape corresponding to the outer shape of the seat bag 2B is formed. Specifically, the seat cover 1A of the seat cushion 2A
The front cover piece 1a and the rear cover piece 1b are sewn together to form a part that covers the center part of the seat cushion 2A, and the cover pieces 1c and 1d are sewn to both side edges of this part. This forms a portion that covers the side surface of the seat cushion 2A. On the other hand, seat bag 2
The seat cover 1B of B is made by sewing together an upper cover piece 1e and a lower cover piece 1f to form a part that covers the center part of the seat bag 2B, and sewing the cover pieces 1g and 1h to both side edges of this part. This forms a portion that covers the side surface of the seat bag 2B.

Such seat covers 1A and 1B are each integrated with a seat pad and are held in a rounded shape as a whole by being fitted around the outer periphery of the pad.

Further, each of the cover pieces 1a to 1h constituting such seat covers 1A and 1B has a wading 6 made of slab urethane attached to the back side of a skin 5 made of non-breathable vinyl chloride, for example.
The configuration is such that no back base fabric is applied to the back side of the wadding 6.

Then, as shown in FIG. 3, the cover pieces 1a to 1h are overlapped so that their edges are in contact with each other, and the sewn parts 1C are sewn together as shown in FIG. It is sewn together using a sewing machine. That is, in this operation, sewing is performed using the sewing needle 9 while the sewing portion 1C is held down by the throat plate 7 provided on the bed 11 and the presser piece 8 on the sewing needle 9 side.

Further, the cover pieces 1a to 1h as described above are cut into a predetermined shape by cutting a raw fabric 12 as shown in FIG. 5, for example. This raw fabric 12 is obtained by laminating a skin 5 and a wadding 6 together. Then, on the surface of this raw fabric 12, a mesh-like coating portion 1 is formed as a whole corresponding to the cut shape of the cover pieces 1a to 1h.
0 is set. That is, this coating part 10 is provided by applying a molten liquid such as vinyl chloride, and is formed corresponding to the sewn part 1C located at the peripheral edge of each cover piece 1a to 1h. After cutting the pieces 1a to 1h, they are arranged in a band shape along the respective sewn portions 1C.

FIG. 6 shows the manufacturing position of such a raw fabric 12. In this device, after the skin 5 supplied from the delivery roller 13 and the wadding 6 supplied from the delivery roller 14 are bonded in the lamination processing section 15, the skin 5 is supplied to the coating processing section 16 and the wadding 6 is bonded to the wadding 6 supplied from the delivery roller 14. 10.

As shown in FIG. 7, the coating processing section 16 includes a receiving roller 17 for supporting the original fabric 12 sent out from the laminating processing section 15, and a coating section 10 on the original fabric 12 on the receiving roller 17.
A moving roller 18 for coating and forming, a control device (not shown) for controlling the movement of the moving roller 18 in the width direction of the web 12, and a supply device for supplying the above-mentioned melt for coating onto the surface of the moving roller 18. 19. That is, in this coating processing section 16, as the raw fabric 12 is fed, the moving roller 18 is moved in a direction substantially perpendicular to this, so that the surface of the wadding 6 of the raw fabric 12 is coated in an oblique direction as shown in FIG. A strip-shaped coating line 10a is formed on the surface, and by arranging a plurality of such coating processing sections 16 in a plurality of stages, a mesh-like coating section 10 in which a plurality of coating lines 10a intersect can be obtained.

The raw fabric 12 thus formed is immediately cut into two equal parts in the width direction, and the sewing part 1 is cut into two equal parts in the width direction, as shown in FIG.
The cover pieces 1a to 1h are formed as cover pieces 1a to 1h having a coating portion 10 on the peripheral edge portion C.

The cover pieces 1a to 1h obtained in this way are
During the sewing operation, the aforementioned throat plate 7 and presser piece 8 slide on the coating portion 10 on the surface of the wadding 6, as shown in FIG. Therefore, compared to the case where the throat plate 7 and the presser piece 8 directly contact the surface of the wading 6, the friction coefficient of the contact surface itself becomes smaller, the surface strength of the wading 6 increases, and the concave shape caused by the presser piece 8 also becomes smaller. Since it is small and gentle, the overall frictional resistance is reduced.

Thereby, the sewn portions 1C of the cover pieces 1a to 1h can be smoothly slid, and the work efficiency of the sewing work can be improved.

In addition, in the above embodiment, the coating portion 1 has a plurality of coating lines 10a orthogonal to each other.
The pattern shape of the coating part 10 can be selected as appropriate depending on the size of the original fabric and the shape of the cover piece. For example, as shown in FIG. Various methods are possible, such as one having a plurality of coating lines 10b. Further, the coating part 10 does not necessarily need to be provided all around the cover piece, and even if it is not necessarily provided in correspondence with the sewing position, the frictional resistance during sewing work is reduced and the sewing part 1C can be smoothly formed. It can be slid.

[Effect of idea]

As explained above, according to the present invention, the coating part provided on the original fabric of the cover piece reduces the friction between the throat plate or presser plate of the sewing machine and the sewing part of the cover piece during the sewing operation of the cover piece. It becomes possible to reduce the resistance and smoothly slide the sewing part, thereby improving the work efficiency of sewing work.

In addition, since the coating portion is formed on the original fabric before it is cut into cover pieces, this work can be performed all at once and efficiently, making it possible to reduce manufacturing costs and the like.
