Description

[Detailed Description of the Invention] The present invention relates to a seat skin covering a cushion body such as a seat bag or a seat cushion.

Conventionally, this type of seat skin is made by forming cut pieces corresponding to the shape of each side surface of the cushion body using sheet materials such as genuine leather or synthetic leather, and then forming the cut pieces into a bag shape suitable for attaching to the cushion body. It is constructed by sewing. However, this sheet skin is formed through many processes such as cutting and sewing, and cutting the sheet material results in a large amount of material loss, making it expensive. Moreover, it is not suitable for high-speed production,
Additionally, there is no room for any shortcuts in materials or sewing work, making it quite expensive.

The object of the present invention is to provide a seat skin made of a new material in order to eliminate such drawbacks.

That is, in the seat skin according to the present invention, the seat skin encloses the cushion body, and the skin material is made of various fibers and has a three-dimensional shape that can be attached to the cushion body and has a bag shape with the lower end side open. The bag is knitted and a resin coat is applied to the entire back side of the bag so that it can maintain its three-dimensional shape.

This will be explained below based on the illustrated embodiment.

This skin A is formed of a knitted fabric formed by knitting and molding various fibers. The fibers used in the hoop may be wool, tinsel, or synthetic yarn, and the knitting method may be any method such as front knitting, purl knitting, and widening knitting. The knitting is performed by a high-speed automatic knitting machine, and a three-dimensional bag A with an open lower edge is formed.

This bag A is provided with a resin coat B on the entire back side. To mold the resin coat B, turn the bag body A inside out, overlay a resin film on the back side located on the front side, or apply a resin liquid, and mold it with molds C1, C2, C3, and C4. This can be done by molding. The turned-over bag A is placed over the core mold C4 of the aluminum mold and inserted into the cavity molds C1, C2, and C3, and the resin film or coating resin is welded by steam injected into the core mold C4 to coat it with resin. A backing with B can be formed. This resin coat B is formed on the knitted bag A to maintain its shape, and is provided on the back side so as not to impair its surface properties.

Note that at the same time as this resin coat B is formed, the bag body A is
It is possible to form a wading pattern D having an uneven shape on the surface side. For the molding, hot press, welder, hot melt, urethane simultaneous foaming molding, impregnated urethane foaming molding, etc. can be employed. In the illustrated embodiment,
A filling d1 such as a urethane slab, a urethane mold, or an impregnated urethane is sandwiched between a core mold C4 having an uneven surface and a cavity mold C3, and then steamed. A method of curing is used.

The sheet skin A constructed in this manner is applied to the cushion body with the surface on which the resin coat B is formed facing back. At this time, even if the sheet skin A is knitted, its specific form is maintained by the lining with the resin coat B, so it can be easily assembled to the cushion body and will not lose its shape even after being attached. Since it can be assembled without exposing any seams or the like on the front surface side by simply sewing the side openings, the cushion body can be wrapped in a fashionable manner without being wrapped in a fashionable manner.

Note that the cushion body to which this seat skin is applied is not limited to those for vehicles such as seat bags, seat cushions, headrests, armrests, etc., but may be for a wide variety of furniture.

As described above, according to the seat skin according to the present invention, cutting work can be omitted since it is formed from a knitted fabric, and moreover, it can be formed into a bag-like shape by opening the lower end in accordance with the shape of the cushion body. Because it is held and formed, it can be attached by simply covering it over the cushion body, and even when sewing the opening on the lower end side, it can be assembled without exposing the seam to the surface side, and it can also be used for decorative purposes.
Accessories such as a suspension cloth can also be organized together with the main body, making it possible to reduce costs without requiring much effort.
