Abstract

At least a part of a seat cover (4) covering a vehicle seat (1) is formed of a seat-cover skin material (5) including a surface material (10), a cushion material (11), and a backing material (12) which are laminated in this order and are integrally joined together, and a stitch portion (20) at which the surface material (10) and the backing material (12) are sewn together, wherein an elongation percentage of the surface material (10) is greater than an elongation percentage of the backing material (12) when the same load is applied.

Claims

1. A seat-cover skin material comprising:

a surface material;

a cushion material;

a backing material, the backing material being a thin cheesecloth; and

a stitch portion at which the surface material and the backing material are sewn together, wherein;

the surface material, the cushion material and the backing material are laminated in this order and are integrally joined together; and

an elongation rate of the surface material is greater than an elongation percentage of the backing material when the same load is applied.

2. The seat-cover skin material according to claim 1, wherein a thickness of the cheesecloth is equal to or less than several hundred μ

m.

3. A seat cover comprising:

a seat-cover skin material including;

a surface material;

a cushion material;

a backing material, the backing material being a thin cheesecloth; and

a stitch portion at which the surface material and the backing material are sewn together, wherein;

the surface material, the cushion material and the backing material are laminated in this order and are integrally joined together; and

an elongation rate of the surface material is greater than an elongation percentage of the backing material when the same load is applied.

4. The seat cover according to claim 3, wherein a thickness of the cheesecloth is equal to or less than several hundred μ

m.

5. A vehicle seat covered with a seat cover, at least a part of the seat cover comprising:

a seat-cover skin material including;

a surface material;

a cushion material;

a backing material, the backing material being a thin cheesecloth; and

a stitch portion at which the surface material and the backing material are sewn together, wherein

the surface material, the cushion material and the backing material are laminated in this order and are integrally joined together; and

an elongation rate of the surface material is greater than an elongation percentage of the backing material when the same load is applied.

6. The seat according to claim 5, wherein a thickness of the cheesecloth is equal to or less than several hundred μ

m.

7. A seat-cover skin material comprising:

a surface material;

a cushion material;

a backing material; and

a stitch portion at which the surface material and the backing material are sewn together, wherein;

the surface material, the cushion material and the backing material are laminated in this order and are integrally joined together;

an elongation rate of the surface material is greater than an elongation percentage of the backing material when the same load is applied; and

a depth of a depression of the stitch portion on a front surface of the skin material is larger than a depth of a depression of the stitch portion on a back surface of the skin material.

8. A seat cover comprising:

a seat-cover skin material including;

a surface material;

a cushion material;

a backing material; and

a stitch portion at which the surface material and the backing material are sewn together, wherein;

the surface material, the cushion material and the backing material are laminated in this order and are integrally joined together;

an elongation rate of the surface material is greater than an elongation percentage of the backing material when the same load is applied; and

a depth of a depression of the stitch portion on a front surface of the skin material is larger than a depth of a depression of the stitch portion on a back surface of the skin material.

9. A vehicle seat covered with a seat cover, at least a part of the seat cover comprising:

a seat-cover skin material including;

a surface material;
