Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an integrally molded product of a facing material and a padding material. To explain in more detail, it is formed by bonding a backing material to the back side of the facing material. This invention relates to an integrally molded product of a facing material and a pad material, which is formed by molding the facing material into a desired shape, injecting a stock solution of foamed synthetic resin into the backing material side of the facing material, and foam-molding the pad material.

(Prior Art) Conventionally, integrally molded products of a covering material and a pad material have been used in seat cushions, seat bags, headrests, etc. of seats of vehicles, etc.
There are products that do not require separate work to integrate the facing material and padding material, improving work efficiency. In this case, if the skin material forming the covering material is a breathable skin material 12 such as cloth, as shown in FIG. It was easily impregnated and there was a risk of staining the skin material 12. For this purpose, as shown in FIG. 5 or 6, a backing material 16 made of a synthetic resin sheet such as a vinyl chloride sheet or a backing material 17 made of a foamed urethane sheet is bonded to the back side of the skin material 12. Surface material 14,
15 respectively.

(Problems to be solved by the invention) However, in the case of the facing material 14 using the backing material 16 made of vinyl chloride sheet shown in FIG. 5, it is possible to shape it by vacuum forming etc. The padding material 13 on the back side of the padding material 14 has the disadvantage that the feel is directly given to the seated person etc., the tactility is reduced, and it does not have breathability. In the case of the facing material 15 using the material No. 17, it has excellent tactility, but it is difficult to vacuum form and only foam pressure molding is required, so it has the disadvantage that it is not possible to form shapes or form fine patterns. Ta.

(Means for solving the problem) The present invention was made in view of the above-mentioned problems, and its feature is that the facing material is formed by bonding a backing material to the back side of the facing material. In an integrally molded product of a facing material and a pad material, which is formed by molding into a desired shape, injecting a foamed synthetic resin stock solution into the backing material side of the facing material, and foam-molding the pad material, the skin of the facing material When the backing material to be joined to the material is viewed from above, the part that requires shaping is formed by the first backing material made of a synthetic resin sheet, and the part that requires a soft feel is made of a foamed urethane sheet. The point is that it is formed of a second backing material.

(Function) According to the present invention, the first backing material has excellent vacuum formability and can be easily formed into a desired shape pattern, and the main part of the sheet has a soft feel and breathability. The appearance and feel of integrally molded products such as sheets can be significantly improved.

(Example) An example of the present invention will be described in detail below with reference to the drawings.

Figures 1 to 3 each schematically show an example of an integrally molded product of a covering material and a pad material according to the present invention, and in this example, it is applied to a seat cushion for a seat of a vehicle, etc. Although the present invention is shown as a case in which the present invention is a seat bag or a headrest, it can be similarly applied to an integrally molded product such as a seat bag or a headrest.

The seat cushion 1 is formed of a seat frame (not shown) and an integrally molded product 4 of a covering material 2 and a padding material 3 that are integrated into the seat frame. etc. are installed.

The facing material 2 includes a facing material 5 made of cloth or a synthetic resin sheet on the front side, first and second backing materials 6 bonded to the back side of the facing material 5,
It is formed from 7. The first and second backing materials 6, 7 are joined at different positions when viewed from above, and the two backing materials 6, 7 are not laminated.

The part where the first backing material 6 is joined corresponds to the part of the side of the seat cushion 1 that requires shaping, and the part where the second backing material 7 is joined corresponds to the part where the seat cushion 1 is seated. The main part is the part that comes into contact with the user, and is formed to correspond to the part that requires a soft feel. The first backing material 6 is formed of a vinyl chloride sheet as a synthetic resin sheet, and the second backing material 7 is formed of a foamed urethane sheet.

The first bucking material 6 is joined to the skin material 5 to form the first facing material 2a, and the second bucking material 7 is joined to the same skin material 5 to form the second facing material 2a.
b, and these first and second facing materials 2a,
Cut 2b into the shape of sheet cushion 1,
The facing material 2 of the seat cushion 1 is formed by joining these together by sewing, heat welding, or the like.

As shown in FIG. 3, this facing material 2 is vacuum formed using a vacuum forming mold 11, and a fine pattern or shape is formed on the part of the first facing material 2a to which the first backing material 6 is bonded. Next, a stock solution of foamed synthetic resin is injected into the backing materials 6 and 7 sides of the facing material 2 to foam-mold the pad material 3, thereby forming an integrally molded product 4 of the facing material 2 and the pad material 3.

In the above embodiment, the same skin material 5 is used for the first and second covering materials 2a and 2b, but different skin materials may be used.
Furthermore, when integrally molding the upholstery material 2 and the pad material 3, it is optional to insert the seat frame, frame line, and other members when pouring the foamed synthetic resin stock solution and mold them integrally with the pad material 3.

(Effect of the invention) The above is the structure of an embodiment of the integrally molded product of the facing material and the padding material according to the present invention. It can be vacuum formed and can be shaped and finely patterned, and the part where the second backing material is joined has excellent feel and breathability, and the overall appearance and feel are both excellent. It is possible to obtain an integrally molded product of the facing material and the pad material.

In the above embodiment, the first and second backing materials 6 and 7 were used, but a third vinyl chloride sheet material or the like may be used to form an integrally molded product with a plurality of different textures. I can do things.
