Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a seat device and a seat cover, and more particularly to a seat device and a seat cover having a light emitting function.

[0002]

Conventionally, in a seat apparatus and a seat cover of this type, for example, for a vehicle, a fluorescent paint is mixed into a material of a bead of the seat, and the material is irradiated with black light. A material that emits light, a material that mixes a luminous pigment into the material of the bead of the sheet and emits light by its light storage effect, or a material that mixes a fluorescent paint into the material of the bead and emits light by irradiating it with black light and so on.

[0003] However, in the case of using the above fluorescent paint,
There is a disadvantage that light emission cannot be controlled. On the other hand, in the case of using the above-described black light, only a portion irradiated with the light emits light, so that there is a surface on which it is difficult to obtain a continuous light emitting effect.

Therefore, for example, it is conceivable to display light by incorporating an optical fiber into a sheet. However, since an optical fiber mainly emits light in a point-like light emitting portion,
A continuous light emitting effect cannot be obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a seat device and a seat cover which emit light continuously and provide an unprecedented decorative effect.

[0006]

According to a first aspect of the present invention, an electroluminescent fiber is provided at a stitched portion of a skin.

According to a second aspect of the present invention, in the seat device, a bead is provided in the stitched portion, and the electroluminescent fiber is provided in the bead.

According to the second aspect of the present invention, by arranging the electroluminescent fibers in the bead, the electroluminescent fibers can be arranged on the sheet device simultaneously with the sewing of the bead.

Further, according to a third aspect of the present invention, in the seat apparatus, a bead-shaped molded body having a cover portion covering the electroluminescent fiber and a sewn portion provided integrally with the cover portion is formed. The attachment portion is sewn to the stitched portion.

According to the third aspect of the present invention, since the ball-shaped molded body is previously formed on the electroluminescent fiber by integral molding, the electroluminescent fiber can be arranged by sewing the portions to be sewn. And the cover protects the electroluminescent fiber.

According to a fourth aspect of the present invention, an electroluminescent fiber is provided at a stitched portion.

According to the configuration of the fourth aspect, a continuous linear light emitting effect can be obtained by the electroluminescent fiber provided at the stitched portion.

According to a fifth aspect of the present invention, there is provided a seat cover wherein a bead is provided at the stitched portion, and the electroluminescent fiber is provided within the bead.

According to the configuration of the fifth aspect, by arranging the electroluminescent fibers in the bead, the electroluminescent fibers can be arranged on the seat cover simultaneously with the sewing of the bead.

Further, the seat cover according to a sixth aspect of the present invention forms a bead-shaped molded body having a covering portion covering the electroluminescent fiber and a sewn portion provided integrally with the covering portion.
The sewn portion is sewn to the stitched portion.

According to the configuration of claim 6, since the ball-shaped molded body is previously formed on the electroluminescent fiber by integral molding, the electroluminescent fiber can be arranged by sewing the parts to be sewn together. And the cover protects the electroluminescent fiber.
