Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin used for a vehicle seat, a home cushion, and the like, and more particularly to a skin which is prevented from being charged with static electricity.

[Related Art] In a vehicle seat of an automobile or the like, when static electricity is charged, it gives a discomfort when sitting down and tends to adhere dust. For this reason, it has been practiced to cover a skin with a static electricity removing function on a cushion. Conventionally, a skin having the following structure has been used to remove static electricity.

Use a conductive material for the skin material. For example, weaving the skin by mixing conductive yarn with commonly used ordinary yarn,
The knitting imparts conductivity to the epidermis.

The material of the skin is subjected to water absorption. This is based on the principle that the conductivity is improved by having water absorption, and is performed by, for example, coating the material of the skin with a water-absorbing resin.

[Problems to be Solved by the Invention] However, in the structure, the material of the skin cannot be applied to a single piece of leather or synthetic leather, and the applicable range is limited. In addition, the structure has poor ability to maintain water absorption and cannot have conductivity for a long period of time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a skin body that can have conductivity for a long time regardless of the material of the skin.

[Means for Solving the Problems] According to the present invention, a conductive base cloth is directly or indirectly superimposed on the back side of a skin covering a cushion, and the skin and the base cloth are connected by a conductive connecting member. It is characterized by having.

[Action] By the structure in which the skin and the conductive base cloth are connected by the conductive connection tool, static electricity charged on the skin flows to the base cloth,
The electrostatic charge of the epidermis is prevented.

EXAMPLES Hereinafter, the present invention will be described with reference to examples illustrated.

In FIGS. 1 and 2, a conductive base cloth 2 is superimposed on the back side of a skin 1 to form a skin body. The skin 1 is a pad 5 such as a vehicle seat or a home cushion.
(See FIG. 4), which is cut into a shape and dimensions that allow covering of the target pad 5. The base fabric 2 is directly superimposed on the back surface of the skin 1. The base fabric 2 is formed to have conductivity, and is preferably superimposed on the entire surface of the skin 1. The base fabric 2 is provided with conductivity by, for example, mixing and weaving or knitting conductive yarn with ordinary yarn, or sandwiching conductive cotton between two cloths. The skin 1 and the conductive base cloth 2 thus superimposed are sewn together by the conductive thread 3. By suturing the conductive thread 3, the skin 1 and the base cloth 2 are integrated to form a skin body. However, since the conductive thread 3 connects the skin 1 and the base cloth 2 to form a kind of electric circuit. The outer skin 1 is electrically connected to the base fabric 2 via the conductive yarn 3. In a state where the pad is covered by using such a skin, static electricity generated in the skin 1 flows from the electric yarn 3 to the conductive base cloth 2. For this reason, electrostatic charging of the skin 1 can be prevented, and discomfort at the time of sitting and dust adhesion due to static electricity can be prevented. Even if a single piece of genuine leather or synthetic leather is used as the skin 1, electrostatic charging can be prevented.
The degree of freedom in selecting the material can be increased, and the conductivity can be maintained for a long time. The conductive base cloth 2 can be electrically connected to, for example, a metal sheet frame or a vehicle body, or can be grounded by an earth wire.
Can also be prevented from being charged.

FIG. 3 and FIG. 4 each show another embodiment of the present invention.

In FIG. 3, a part of the skin material formed by superimposing the skin 1 and the conductive base cloth 2 is a hanging portion 6 to the pad, and the hanging portion 6 is formed by the conductive yarn 3. By being sewn, the skin 1 and the base cloth 2 are electrically joined.

On the other hand, in FIG. 4, the upper surface of the pad 5 is covered in a state where the skin 1 and the conductive base cloth 2 are overlapped, and an accessory button 4 is attached. The accessory button 4 is formed of a plastic mixed with a conductive powder such as a conductive metal or carbon powder, and furthermore, is coated with a conductive metal film or the like to form the shape shown in the drawing so as to have conductivity as a whole. Have been. By inserting the accessory button 4 so as to penetrate the skin 1 base cloth 2 and the pad 5,
The skin 1 and the base cloth 2 are electrically connected. Therefore, the structure shown in FIGS. 3 and 4 can prevent electrostatic charging of the skin 1, and can provide the same operation and effect as those of the above-described embodiment.

In the present invention, another cushioning material may be interposed between the skin 1 and the conductive base cloth 2 as long as the structure connects the conductive skin with the conductive base 2. May be interposed between them.

[Effects of the Invention] As described above, according to the present invention, since the conductive base cloth is superimposed on the skin and connected with a conductive connecting member, the electrostatic charging of the skin can be prevented, and any material can be used. It has an effect that it can be applied to the epidermis and is capable of preventing static charge for a long time.
