Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a seating surface of a vehicle seat (seat) such as an automobile,
Specifically, the present invention relates to a seat seat surface structure including a skin member, a wadding, and a wadding cover that are integrally sewn together to have a decorative groove on the surface, and a foam cushion material covered with the skin member. is there.

(Problems to be Solved with Prior Art) In a vehicle seat, as shown in FIG. 3, a decorative groove (a) formed by sewing a skin member (1) on a seat surface.
Some have (a).

This is a skin made of woven fabric, a wadding made of plate-shaped foam (urethane foam slab material),
The three members of a wadding cover such as a non-woven fabric are laminated and sewn together to form a skin member, and a foam cushion material is covered with this display member.

In the above skin member, the wading is crushed by sewing, so that a substantially U-shaped ornamental groove is formed on the seat surface, which is the surface of the seat, along the sewn portion.

By the way, in order to clearly (clearly) provide the decorative groove of the skin member on the seating surface of the seat, the suspending member is integrally fixed to the back side of the sewn portion of the skin member, and the suspending member is cushioned. There are a structure in which the insert wire embedded in the material is suspended by binding with a hog ring, and a structure in which the skin member is adhered to the surface of the cushion material.

That is, in order to form the decorative groove in the skin member clearly on the surface of the seat, it is due to the hanging structure or the bonding structure for the cushion material.

The former will be described with reference to FIGS. 3, 4, and 5 (A).

The decorative grooves (a) and (a) shown in FIG. 3 are formed by suspending the skin member (1) with respect to the cushion body (2) as shown in FIG. That is, as shown in FIG. 5 (A), a foam cushion material (2) formed by molding a bag-shaped suspending material (1a) into which a trim wire sewn on the back surface side of a skin member (1) is inserted. It is formed by binding the insert wire (2b) embedded in the bracket) with the hog ring (2c). The cushion material (2) corresponding to the sewn portion (10) of the skin member (1) is formed with a groove (2a).

As for the latter, as shown in FIG. 5 (B), the adhesive agent (2d) (2d) is applied to the back surface side of the skin member (1) along the sewn part (10) of the skin member (1). , This adhesive (2
d) (2d) is a structure in which the skin member (1) is bonded to the surface of the cushion material (2).

In addition, in FIG. 5 (A) and (B), (11) in the figure
Is a skin, (12) is a wadding, and (13) is a wadding cover.

Therefore, in the former hanging structure, the decorative groove (a) clearly appears on the skin of the seat, but the trim wire, the insert wire (2b), and the edge of the concave groove (2a) of the cushion material (2) are not. There is a feeling of foreign matter, which makes it uncomfortable to sit on. Also, the hog ring (2c) has a trim wire and an insert wire (2c).
Since the binding of b) occurs, there is a problem that a metallic contact sound is generated.

On the other hand, also in the latter case, since the display member (1) is adhered with the adhesives (2d) and (2d), it is difficult to apply the adhesive uniformly, the sheet surface becomes uneven, and the cured adhesive (2
There is a defect that d) and (2d) give a feeling of foreign matter, and the decorative grooves (a) and (a) do not clearly appear on the sheet surface, and the appearance of the sheet is impaired.

(Means to be solved) Therefore, an object of the present invention is to make it possible to form a clear decorative groove on a seat surface of a vehicle seat without employing the suspending means and the adhering means. .

Therefore, the present invention is a skin member formed by integrally sewing a laminated body including a skin, a wadding, and a wadding cover. In a vehicle seat covering a foam cushion material, the wading cover is sewn on the skin member. A plate-shaped shape-retaining plate having rigidity is integrally sewn along the portion, and the shape-retaining plate is placed in a concave recess or groove provided on the surface of the cushion material covered with the skin member. It is a thing. Therefore, due to the rigidity of the shape retaining plate integrally sewn on the back surface side of the skin member, the sewn portion is located on the shape retaining plate side, so that a deep decorative groove is formed.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 (A) and (B).
Will be explained.

FIG. 1 shows a state before the skin member (1) is covered with the foam cushion material (2), and the skin member (1) is the same as the conventional one, that is, the skin (11), the wadding (12), and the wadding cover ( The three members of 13) are laminated and the predetermined parts are sewn together with a sewing machine or the like to be integrated. At the time of this sewing,
The shape-retaining plate (14) is overlaid on the wading cover (13) side and integrally sewn. In the figure, (15) shows a stitched portion, and (a) shows a decorative groove (pattern) formed by stitching.

The shape-retaining plate (14) is a plate material having substantially the same overall length as the sewn part (15) and having rigidity such as hard vinyl chloride and soft polyethylene, and its width in the lateral direction is about 2 to 7 cm. , Its width direction center is integrally sewn.

2 (A) and (B) show a state in which the cushion material (2) is covered with the skin member (1), and the cushion material (2) is shown.
Is a foamed body (for example, urethane foam) which is molded into a substantially outer shape of a sheet as in the conventional case.

A cushion material (2) shown in FIG. 2 (A) has a concave shape wider than the shape retaining plate (14) on the surface of the cushion material (2) corresponding to the shape retaining plate (14) of the skin member (1). Depression (2
1) is provided so that the skin member (1) around the ornamental groove (a) can be drawn into the recess (21), and is placed in the recess (21) of the shape retaining plate (15). It is placed.

Further, FIG. 2 (B) shows that a shallow groove (22), which is slightly larger than the shape-retaining plate (14), is provided on the surface in the portion where the shape-retaining plate (14) is placed. The shape retainer plate (14) provided on the back surface side of the skin member (1) is fitted in (22).

Thus, the decorative groove (a) appears deep and clearly on the seating surface of the seat without adhering or suspending the skin member (1).

(Effects) According to the present invention, the skin, the wadding, the wadding cover, and the shape retaining plate are overlapped and sewn together, and the shape retaining plate is provided on the surface of the cushion member covered with the skin member. Alternatively, by placing the groove in the concave groove, a groove for decoration is formed on the surface and the groove shape is maintained.

Therefore, unlike the conventional products, the decorative groove is formed on the seating surface of the seat without suspending or adhering the skin member to the cushion material. Therefore, unlike the conventional products, the suspending material, the trim wire, the insert wire and the like are not required, and the attachment of the skin member to the cushion material is improved.

In addition, since the shape retaining plate can be sewn at the same time when the skin member is sewn, the productivity of the skin member is improved. Moreover, since the outer skin and the wadding are pressed against the shape retaining plate by sewing, the sewn portion does not pop up, float, or sink, so that it is possible to provide a vehicle seat with a good seating surface appearance.
