Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to vehicle seats such as automobile seats, and more specifically to vehicles having a block-like three-dimensional pattern on the surface in order to improve the aesthetic appearance of the surface. This relates to sheets for use.

(Prior Art) Conventionally, vehicle seats with a block-like three-dimensional pattern on the surface to provide a good feel and improve appearance have been made of molded foam (for example, urethane foam), as shown in Figure 5. etc.) A cushion main body (hereinafter referred to as the main body) 10 is overlaid with a foamed cushion auxiliary body (hereinafter referred to as the auxiliary body) 2 made of a plate-shaped slab material, and these are covered with a skin member 3. Hanging holes 10a, 10a..., 2a, 2 are provided in the main body 10 and the auxiliary body 2 while pulling the hanging member 4 fixed to the back surface of the skin member 3.
It was formed by inserting the spring 5 into the frame 6 and attaching it to a fixed member such as a spring 5 stretched over the frame 6. That is, the area around the hanging hole 2a in the auxiliary body 2 is crushed by hanging the skin member 3 to form a recess on the surface, and by hanging each hanging member 4..., each hanging hole 2a is crushed. By crushing the auxiliary body 2 between the inserting members 4 in a linear manner, a block-like three-dimensional pattern was formed on the surface (Fig. 6).

Therefore, a vehicle seat having such a structure has a hard main body 1.
Since the soft auxiliary body 2 is stacked on top of the 0, the seat surface feels good and is comfortable to sit on.Also, since the auxiliary body 2 is suspended together with the skin member 3, there is no unevenness on the seat surface. A three-dimensional block pattern is formed, giving the sheet a good appearance.

However, since a depression is formed on the surface of the sheet by crushing the auxiliary body 2, the depth of the depression is approximately equal to the thickness of the auxiliary body, and a deep depression is obtained. There was a problem that prevented me from doing so.

Note that in order to create deep depressions, it is sufficient to use a thick auxiliary body, but if such a auxiliary body is used, countless irregular wrinkles will occur on the surface of the sheet, which will affect the appearance of the sheet. There was a particularly bad flaw.

(Objective) The object of the present invention is to form a block-like three-dimensional pattern that is more three-dimensional and superior in design than the conventional products, without changing the thickness of the conventional auxiliary body.

(Structure) The present invention provides cut-in grooves in a grid pattern on the side of the auxiliary body of the main body of the conventional product, and also provides the hanging holes in the cut-in grooves, so that the auxiliary body and the skin member can be attached to the main body. It is formed by being cut into a groove and suspended by a hanging member provided on the skin member.

That is, by inserting the auxiliary body and the skin member into the grooves of the main body and suspending them, deep grid-like grooves are formed on the sheet surface, and these grooves allow the skin member to It controls wrinkles that occur.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows a vehicle seat (seat cushion) according to the present invention.
The concave groove formed by the hanging of the button ro is a decorative button, and a hanging member is attached to the leg of this button ro, into which the skin member 3 is suspended. Therefore, the portions surrounded by grooves A, A, . This will be explained in detail with reference to FIGS. 2 and 3.

In the figure, the same reference numerals as those in FIG. 6 indicate the same members. 11', 11' are provided, and cut grooves 1b, 1b... are bored in a grid pattern in the part surrounded by the raised portions 11..., and at the intersections of the cut grooves 1b... Hanging hole 1a, 1
A... is opened. In the illustrated example, convex portions 12, 12, . It is in. The width and depth of the above-mentioned biting grooves 1b are the same as or less than the thickness of the cushion auxiliary body 2, and if the thickness of the cushion auxiliary body 2 is 20 mm to 30 mm, the width and depth are preferably about 20 mm.

On the upper surface of the cushion main body 1, cushion auxiliary bodies 2, 2' are bonded or integrally formed when the cushion main body 1 is molded, and are fixed to the cushion main body 1 so that the cushion auxiliary bodies 2, 2' do not shift. . The cushion auxiliary bodies 2, 2' are slab materials having excellent flexibility (cushionability) relative to the cushion main body 1, and 2 is large enough to cover the raised parts 11', 11'. is the raised portion 11,
It is large enough to cover only the area surrounded by 11' and 11'. At the positions corresponding to the hanging holes 1a of the cushion main body 1 in the cushion auxiliary bodies 2, 2', there are hanging holes 2a, 2, as in the conventional product.
A′ is provided.

As shown in FIG. 2, the skin member 3 covering the cushion auxiliary bodies 2, 2' has a three-layer structure consisting of a skin, a foam material, wadding, and a wadding cover in the portion corresponding to the convex portion 12 of the cushion main body 1. By forming the block pattern, a more three-dimensional block pattern can be formed. A decorative buttonhole is provided on the surface of the skin member 3, and the legs of the decorative buttonhole are passed through the back side of the skin member 3, and a hanging member 4 is attached to the leg.
One end of is tied.

In this way, the outer skin member 3 is placed over the cushion auxiliary body 2, and each hanging member 4 is inserted into the respective hanging holes 1a, 2a, 2 of the cushion auxiliary body 2 and the cushion main body 3.
a' and pull it in, and when it is tied to the spring 5 with a hogging ring, the recessed groove 1b of the cushion main body 1...
The cushion auxiliary body 2 and the skin member 3 are bitten into the sheet to form the sheet shown in FIG.

Fig. 4 shows a cushion body 1 in which a flat portion 13 is defined as a portion surrounded by grooves 1b, 1b, . By creating a similar structure, the upper surface of the block-like pattern is formed into a flat shape.

(Effects) As described above, in the present invention, the cut-in grooves are provided in the upper surface of the main body of the cushion in a grid pattern, so that the cushion auxiliary body and the skin member are suspended in the cut-in grooves by the hanging member. eaten by. Therefore, the part where the skin member is bitten appears as a grid-like groove on the sheet surface, forming a three-dimensional block pattern on the sheet surface, which is different from the conventional product. Since the cushion auxiliary body is bitten into the grooves of the cushion main body, it has a more three-dimensional appearance, and the grooves can evenly control wrinkles caused by hanging of the skin member, resulting in an attractive design. It is possible to provide vehicle seats with excellent performance and high commercial value.
