Description

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

BACKGROUND ART Conventionally, in reception chairs and the like, the seat and backrest wrinkles are formed by sewing and digging the outer skin into the cushioning material. 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 latitude line pattern is generated, which limits the design, and furthermore, the sewing operation is not easy.

Present invention P4 In view of the above, a large number of grooves are formed on the surface of the buffer sheet with dimensions corresponding to the interval between the wrinkles, and by covering these grooves with the outer skin and pulling the outer skin in the direction in which the grooves extend, the outer skin is formed. By digging into the groove to form wrinkles, even if the cushioning material is thin, the wrinkles will be neatly formed.
Wrinkles can be easily formed without the need for force ζ or parallel pattern.

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

In Figure 1, the seat portion (1) of the seat has wrinkles (3) formed in its central rear portion (2), and wrinkles formed in its front portion (4) and both side portions (5). do not have. Similarly to the seat, the backrest (6) does not have wrinkles (3) in its central lower portion (7).

The seat part (1) and the backrest (6) each have a padding αB made of thick and strong foam, and are layered on top of this padding.
The padding A2 is made of a thin and stiff foam material, and the front side of the padding 0 is bound by the outer skin α3, the back side is covered with a fabric αψ such as a metal cloth or non-woven fabric, and the padding 0 is joined together by sewing means. ing.

The wrinkles (3) of the epidermis α3 form a large number of grooves αG that are parallel to each other and extend in the front-rear direction or the vertical direction on the surface of the filling 02 that contacts the epidermis, and the epidermis 03 is placed over the front side with the grooves, and the opposite side is By applying the lining fabric aΦ to the grooves, sewing these fillings, the outer skin, and both ends of the lining fabric together, applying tensile force to the outer skin in the direction of the groove, and biting the part of the outer skin corresponding to the groove αQ into the groove. to form.

As a method of applying tensile force to the outer skin a3, in addition to the above-mentioned sewing method, after covering the buffer sheet αG in which the outer skin αe, the stuffing α2, and the lining fabric (141) are combined, the stuffing α°C is covered with the sheet α0.
by pulling the end αη with the tensioning means Oe to the specified mounting location α
It may also be connected to 9.

The grooves OG are formed from the wrinkled surface to the side surfaces by adding grooves to the plane (to) of the filler a2 as well as the second side surface Q as shown in the ninth figure. The groove (15a) on the side surface may be formed offset between the grooves αQ and aoo on the plane as shown in Fig. A, or may be aligned with the groove αe on the plane as shown in Fig. B. As shown in FIG.

Regarding the shapes of the grooves, the planar grooves 00 can be those in Figures A to ■, and the side grooves (15a) can be those in Figures A to E, but they are not limited to these and various shapes are possible. Conceivable.

The wrinkles are not limited to a part of the seat or backrest, but may extend to the entire surface, and the seat is used not only for automobiles but also for home and work use, and the seat shape is also suitable for seven-seater 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 filler, covers the surface on the groove side with a skin, and pulls the skin in the direction of the groove so that a part of it bites into the groove. Since the skin is configured to form wrinkles on the epidermis, the formation of wrinkles is easy.

Claims (1)

[Claims] / A plurality of grooves (biparallel to each other) are formed on the surface of a padding having cushioning properties, a skin is covered on the surface on the groove side, and a part of the skin is pulled in the direction of the groove. A method for removing wrinkles from the surface of a buffer sheet by digging into the surface of the cushioning sheet to form wrinkles on the surface of the buffer sheet. A method for removing wrinkles from the surface of a buffer sheet according to item 1 of the patent, which applies a tensile force in the direction of the grooves to the skin and causes a portion of the tension to dig into each area to form wrinkles on the skin.
