Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vehicle seat such as an automobile seat, and more particularly, to an improvement of a vehicle seat having a rectangular button pattern on its surface.

(Prior art) As shown in FIG.
The structure is as shown in the figure. That is, the hanging cloth 3 is stacked on the back side of the trim cover 1 and sewn into a rectangular shape using a sewing machine to form the button forming part 1a on the trim cover 1, and the hanging cloth 3 is made of foam material. It is inserted into a through hole 2a provided in the cushion body 2, and the tip of the hanging cloth 3 is tied to a support member 4 such as an S spring that supports the cushion body 2 with hogging rings 5, 5. As a result, the hanging cloth 3 is fixed to the trim cover 1 and at the same time the rectangular button pattern a
is formed on the surface of the seat cushion SC.

The trim cover 1 includes a skin 11 made of a fabric, a synthetic resin film, a sheet, etc., and a wadding 12 made of foam (ureta foam slab material).
and a wading cover 13 made of non-woven fabric, etc., and by sewing this laminate into a rectangular shape as described above, the wading 1 at the sewn location is formed.
2 is press-dipped to form the button forming portion 1a.

(Problem to be solved by the invention) The rectangular button pattern a provided on the seat cushion SC as described above wrinkles and twists due to the use of the seat cushion SC.
There was a problem with the appearance of the SC that was noticeable. this is,
This is because the button forming portion 1a of the trim cover 1 is deformed.

Such a problem can be solved by fixing a piece of hard synthetic resin to the back side of the button forming part 1a of the trim cover 1, but if you do this, the piece of hard synthetic resin will feel like a foreign body when you sit on it. , there is a problem that the comfort of sitting is impaired.

Therefore, an object of the present invention is to prevent wrinkles and twists from occurring in the button pattern a, and to prevent the seating comfort from being impaired.

(Means for Solving the Problems) A vehicle seat according to the present invention to achieve the above-mentioned object has buttons made of a laminate made of a skin, foam wadding, and a wading cover sewn integrally into a flat rectangular shape. It consists of a trim cover having a forming part, a hanging material fixed along the sewing part on the back side of the trim cover, and a cushion body covered with the trim cover, and the cushion body has a A through hole of approximately the same size as the planar shape of the button forming portion is provided in the portion covered by the button forming portion, and a foam block having a smaller diameter than the planar shape of the through hole is provided in the through hole. At the same time, a suspension groove is formed between the periphery of the block body and the inner wall surface of the through hole, and a suspension material provided on the back side of the trim cover is inserted into the suspension groove. It is characterized in that it is inserted into the insertion groove and its tip is tied to an insert wire embedded within the cushion body or to a support member that supports the cushion body.

The hanging groove provided in the above cushion body may be provided in a planar rectangular shape on the upper surface of the cushion body,
In addition, a through hole having a rectangular planar shape is opened in the cushion body, a foam block having a small diameter relative to the through hole is inserted into the through hole, and a gap between the block body and the inner wall surface of the through hole is inserted. It is optional to use the gap as a hanging groove.

(Function) The button forming portion of the trim cover is supported by the block surrounded by the hanging groove, and does not deform due to the rebound resilience of the block, so wrinkles do not occur. Never.

In addition, since it is inserted into the hanging material and the hanging groove and does not move, twisting of the button forming part can be prevented.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

In the figure, the same reference numerals as in FIG. 6 indicate the same members, and the explanation thereof will be omitted.

In the figure, 6 indicates a hanging groove provided in a cushion body made of a foam (for example, urethane foam), and the hanging groove 6
A through hole is formed in the cushion body 2 with a planar shape that is approximately the same size as the rectangular button forming portion a provided in the trim cover 1, and a through hole with a planar shape that is smaller in diameter than the through hole and has a thickness that is equal to the thickness of the cushion body 2. It is formed by inserting substantially the same foam block body 7 into the through hole. That is, a gap is created between the block body 7 and the inner wall surface of the through hole, and this gap is used as the hanging groove 6, and the cushion body 2 and the block body 7 are supported by supporting members 4, 4, etc. such as S springs. supported above.

The trim cover 1 and the hanging material 3 fixed to the back side of the trim cover 1 by sewing are formed in the same manner as in the conventional product.

That is, the hanging material 3 is stacked on the back side of the trim cover 1 and sewn into a flat rectangular shape using a sewing machine to form the button forming part 1a on the trim cover 1, and at the same time, the hanging material 3 is integrally attached to the trim cover 1. In the figure, 1b and 1b indicate the sewn parts.

The ends of the hanging material 3 described above are formed into a bag shape, wires 31, 31 are inserted into the bag, and the wires 31, . . . are tied to the supporting members 4, 4 with hogging rings 5, 5. This structure allows the sewn portion of the button forming portion 1a, which is a part of the trim cover 1, to be suspended.

In FIG. 4, a hanging groove 6' having a rectangular plane is bored on the upper surface of the cushion body 2 corresponding to the sewing location of the trim cover 1, and an insert wire 4', The trim cover 1 is embedded in the insert wires 4', 4'.
The button forming portion 1a of the trim cover 1 is hung by tying the hanging material 3 fixed to the back side of the trim cover 1 in the same manner as described above.

A portion 7' surrounded by the hanging groove 6' is defined as a support portion 7', and this support portion 7' supports the button forming portion 1a of the trim cover 1.

In this way, the button forming portion 1a of the trim cover 1
is supported by the block body 7 or the support part 7', and the block body 7 and the support part 7' are made of foam like the cushion body 2, and further,
Since its periphery is suspended by the hanging member 3, the button forming portion 1b is constantly springed upward by the elasticity of the block body 7 and the support portion 7'.

(Effects) As described above, in the present invention, the rectangular button forming portion provided on the trim cover is elasticized by the block body on the cushion body side, so that wrinkles do not occur as in the conventional product. Further, since the hanging material is inserted into the hanging structure of the cushion body and does not move in the front, back, right, and left directions, the button forming portion provided on the trim cover is not deformed by twisting or the like.

Therefore, compared to the conventional products mentioned above, a rectangular button pattern can be clearly formed on the surface of the seat, improving the appearance of the seat, and since no hard synthetic resin material is used, the comfort of sitting is not compromised. .
