Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for creating wrinkles on the surface of a buffer sheet.

Conventionally, some reception chairs and the like have wrinkles in the leather skin of the seat and backrest, and these wrinkles are formed by sewing the skin into a cushion material and digging into it. Therefore, in order to form wrinkles, the cushion needs to have a considerable thickness, and thin cushions are difficult to form wrinkles in. Also, a raphe pattern is generated, which limits the design, and furthermore, the sewing operation is not easy.

In view of the above, the present invention forms a large number of grooves on the surface of a buffer sheet with dimensions corresponding to the intervals between wrinkles, covers the outer skin over these grooves, and pulls the outer skin in the extending direction of the grooves. By biting into the groove to form wrinkles, wrinkles can be formed neatly even when the cushioning material is thin, and wrinkles can be easily formed without the need for a raphe pattern.

The application of the present invention to an automobile seat will be specifically described below.

In FIG. 1, the seat portion 1 of the seat has wrinkles 3 formed in its center rear portion 2, and wrinkles are not formed in its front portion 4 and both side portions 5. Like the seat, the backrest 6 also has wrinkles 3 in its central lower part 7.
is formed, and no wrinkles are formed in the upper part 9 and the parts 10 on both sides.

The seat portion 1 and the backrest 6 each include a padding 11 made of a thick and strong foam, and a padding 12 made of a thin and weak foam superimposed on the padding. 12 is covered with a skin 13 on the front side and covered with a fabric 14 such as a non-woven fabric on the back side, and are joined together by sewing means.

The wrinkles 3 in the epidermis 13 are caused by the filling 1 in contact with the epidermis.
Forming a large number of grooves 15 parallel to each other and extending in the front-rear direction or the vertical direction on the surface of 2, covering the front side with the grooves with the outer skin 13, and applying the lining fabric 14 on the opposite side,
It is formed by sewing these fillings and both ends of the lining fabric of the outer skin together, applying a tensile force to the outer skin in the direction of the groove, and biting the part of the outer skin corresponding to the groove 15 into the groove.

In addition to the above-mentioned sewing method, as a method of applying tensile force to the outer skin 13, after covering the stuffing 11 with a buffer sheet 16 in which the outer skin 13, the stuffing 12, and the lining fabric 14 are combined, the end portion 17 of the sheet 16 is pulled by a tensioning means. It may be pulled at 18 and connected to a predetermined attachment location 19.

By adding the grooves 15 not only to the flat surface 20 of the filling 12 but also to the side surfaces 21 as shown in the fourth figure, wrinkles are formed from the surface to the side surfaces. The groove 15a on the side surface is connected to the groove 15 on the plane as shown in FIG. 4A.
They may be formed offset between the grooves 15 in the plane, or they may be formed to match the grooves 15 on the plane as shown in FIG. The grooves may be aligned, or may be formed irregularly regardless of the grooves on the plane.

As for the shapes of the grooves, the planar grooves 15 may be those shown in FIGS. 5A to 5I, and the side grooves 15a may be those shown in FIGS. 6A to E, but the shapes are not limited to these, and various shapes are possible.

The wrinkles are not limited to a part of the seat or backrest, but may extend to the entire surface, and seats are used not only for automobiles but also for home and work use, and the shape of the seat is also suitable for single-seat seats. This also applies to chaise lounges that can accommodate two or more people.

As described above, the present invention forms a plurality of grooves parallel to each other on the surface of the filling, covers the surface on the groove side with a skin, and pulls a part of the skin in the direction of extension of the grooves at both ends of the skin. Since the grooves are configured to form wrinkles on the epidermis by digging into the grooves, it is extremely easy and efficient to simultaneously dig the epidermis into multiple grooves and create wrinkles as a result. .

Claims (1)

[Scope of Claims] 1. A plurality of grooves parallel to each other are formed on the surface of a stuffing material having cushioning properties, a skin is placed over the surface on the groove side, and both ends of the skin are pulled in the direction of extension of the groove to create a part of the groove. A method for removing wrinkles from the surface of a buffer sheet by digging into the grooves to form groove-like wrinkles on the skin. 2. The grooves are formed on any surface of the filler and another surface that intersects with the surface, and both surfaces are covered with a skin,
The surface of the buffer sheet according to claim 1, wherein a tensile force is applied to both ends of the surface in the direction of extension of the grooves so that a part thereof bites into each groove to form groove-like wrinkles on the skin. How to remove wrinkles.
