Abstract

A cover material for a vehicle seat provides favorable touch while utilizing the texture of a leather material. A cover material for a vehicle seat includes: a leather portion made of natural leather or artificial leather; and a mesh fabric portion bonded to the back side of the leather portion.

First claim

The invention claimed is:

1. A cover material for a vehicle seat, comprising:
a leather portion made of natural leather or artificial leather; and
a mesh fabric portion located on a back side of the leather portion, wherein:
the mesh fabric portion includes an upper-side layer and a back-side layer, the upper-side layer and the back-side layer being formed by being knitted in a different manner from each other, and a surface of the upper-side layer having a greater degree of unevenness than a surface of the back-side layer,
the surface of the upper-side layer includes first interlaced shape portions and second interlaced shape portions that are alternately arranged with one another, and
the first interlaced shape portions have a first mesh size and the second interlaced shape portions have a second mesh size that is smaller than the first mesh size.

2. The cover material for the vehicle seat according to claim 1 , wherein the mesh fabric portion is bonded to a back surface of the leather portion by point contact via the surface of the back-side layer.

3. The cover material for the vehicle seat according to claim 1 , wherein the mesh fabric portion is bonded to the back surface of the leather portion with an adhesive applied to the surface of the back-side layer.

4. The cover material for the vehicle seat according to claim 1 , wherein an elasticity of the mesh fabric portion is higher than an elasticity of the leather portion.

5. The cover material for the vehicle seat according to claim 1 , wherein a weight per unit area of the mesh fabric portion is equal to or larger than 100 g/m 2 .

6. The cover material for the vehicle seat according to claim 1 , wherein the leather portion is made of natural leather or artificial leather processed to have a thickness smaller than that before the leather is processed.

7. The cover material for the vehicle seat according to claim 6 , wherein the leather portion is made of natural leather split to have a thickness equal to or smaller than half of that before the leather is split.

8. The cover material for the vehicle seat according to claim 1 , wherein the first interlaced shape portions and the second interlaced shape portions are formed by interlacing protruded portions configured by upper yarn with one another into a three-dimensional shape.

9. The cover material for the vehicle seat according to claim 8 , wherein the three-dimensional shape is a honeycomb shape.
