Abstract

(57) [Summary] (with amendments) [Purpose] It is possible to stabilize the elongation characteristics of the skin material cut from the abdomen of the raw leather roll, and to maintain a certain height by combining the skin material with the empty back part of the raw leather roll. Enables molding of quality sheets. [Structure] This is a seat cover structure of a genuine leather sheet, in which vinylon is applied to almost the entire back surface of the skin material cut from the vicinity of the abdomen 17 of the raw material, which has a high elongation property. A reinforcing cloth 18 made of a woven fabric or the like is attached by adhesive means, and can be sewn in combination with the skin cut from the back of the original fabric or the like.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to, for example, vehicle seats, and more specifically, seats in genuine leather seats. Regarding cover structure.

0002

[Conventional technology]

Conventionally, this type of real leather sheet 1 has been made into sheets as shown in FIGS. 7 to 11. It consists of a cushion 2 and a seat back 3. For example, the seat back 3 is a seat frame. A main pad 5 formed by foaming into a predetermined shape is attached to the arm 4, and A seat cover 6 is wrapped around the main pad 5.

0003 This seat cover 6 includes a center piece 7, left and right frame pieces 8, and side pieces 9. are cut into a predetermined shape, and each piece 7, 8, 9 is sewn to form the seat cover 6. It is formed. In addition, each piece 7, 8, 9 has a skin material (genuine leather) 10 and a cover. It consists of a pad 11 and a back base fabric 12, and this back base fabric 12 is covered with a cover pad in advance. In some cases, it may be glued to the pad 11.

0004

[Problem that the idea aims to solve]

However, since this skin material 10 is natural leather, as shown in FIG. Sample the leather near the back 16 at the center and the abdomen 17 on both sides of the raw leather fabric 15 shown in the figure. When the elongation properties were measured using For this reason, when material is removed to a position close to the abdomen 17, the outside of the initial finish may be removed. There may be variations in durability such as visual quality, fading and wrinkles, and wear, resulting in a constant high quality sheet. There is a problem in that it is difficult to mold sheets from leather with the same physical properties. If you try to do this, the range T of the material removal part of the original fabric will be limited and the yield will be poor. There was a problem that resulted in a significant increase in costs.

[0005] This invention was made to solve the above-mentioned conventional problems. In addition to stabilizing the elongation characteristics of the skin material to be cut from the Because we can form a certain high quality sheet by combining with skin materials from etc. The purpose is to provide a seat cover structure for genuine leather seats that can be Ru.

[0006]

[Means to solve the problem]

In order to solve the above technical problem, this invention is a seat cover structure of genuine leather sheet. Therefore, among the skin materials cut from the original leather fabric, the skin material cut from the vicinity of the abdomen of the original fabric is A reinforcing fabric made of vinylon-based woven fabric, etc. is applied to almost the entire back side of the skin material, which has strong elastic properties. It is pasted by adhesive means and sewn in combination with the skin cut from the back of the original fabric, etc. The seat cover has a genuine leather sheet structure.

[0007]

[Effect]

With the above configuration, the leather with high elongation near the abdomen can be It suppresses elongation and functions to prevent the appearance of emaciated wrinkles.

[0008]

【Example】

Next, an embodiment of the present invention will be described with reference to the drawings. Genuine leather in this example In the leather sheet 1, for example, the leather near the abdomen 17 of the raw leather fabric 15 is used as a frame piece. When used as the skin material 10a of No. 8, almost the entire back surface of this skin material 10a On the other hand, an adhesive 19 is applied to the reinforcing cloth 18 and bonded. This reinforcing cloth 18 is, for example, This reinforcing fabric 1 A sample was taken from the skin material 10a to which No. 8 was adhered and its elongation characteristics were measured. Figure 5 As shown in FIG. is suppressed, and the elongation is close to that of the leather sampled from the back part 16, and the elongation varies. We were able to obtain results in which the Tsuki Ra was reduced by more than half.

[0009] Therefore, the reinforcing cloth 18 is glued to the skin material 10a cut from the abdomen 17, Furthermore, by attaching the cover pad 11 and the back base fabric 12, it is possible to Even if the seat cover 6 is sewn together with the cut skin material 10, its elongation characteristics Since the properties are close to each other, the occurrence of wrinkles, wear, etc. on the skin material 10a is prevented. As a result, the entire skin material 10, 10a has uniform physical properties, and the sheet material By configuring the cushion side in the same way, high quality genuine leather sheet 1 can be obtained. Can be done. In addition, even if the material is taken from the raw leather fabric 15, as shown in FIG. 6, the raw fabric 1 It is possible to increase the range Ta of the material removal part in step 5 and improve the yield. It is possible to reduce costs.

0010 In the above embodiment, the adhesive 19 is applied to the reinforcing cloth 18 and the area near the abdomen 17 is Although it is illustrated as adhering to the skin material 10a cut from For example, adhesive 19 is applied to the reinforcing cloth 18 in advance and heated to the back surface of the skin material 10a. It may be attached by pressing or the like. In addition, adhesives such as double-sided tape and hot melt Top powder, hot melt film, etc. may be used.

[0011]

[Effect of the idea]

The present invention has the above-mentioned structure, so that the elongated material cut from the abdomen of the raw leather fabric can be By attaching reinforcing cloth to almost the entire back surface of the large skin material, the back of the raw leather fabric is It is possible to obtain elongation characteristics that are almost equivalent to the elongation of the skin material that has been cut into smaller pieces. By combining skin materials, it is possible to ensure high quality sheets, and It is possible to improve the yield of raw leather fabric and reduce costs.
