Abstract

A bordering edge of cover members 2b/2c and a bordering edge of cover members 2d/2e of a sitting portion cover 2 of a seat cover 1 are folded back in a longitudinal direction along raised portions A1 of a sitting portion Aa, creased, and attached to the rest of the members while being smoothly curved in conformance to the raised portions, thus to form a three-dimensional curved shape conforming to a top surface of the sitting portion Aa. A bordering edge of cover members 3b/3c and a bordering edge of cover members 3d/3e of a backrest cover 3 are folded back in a longitudinal direction along raised portions A2 of a backrest portion Ab, creased, and attached to the rest of the members while being smoothly curved in conformance to the raised portions, thus to form a three-dimensional curved shape conforming to a front surface of the backrest Ab.

Claims

1. A seat cover, comprising:

a sitting portion cover for covering a sitting portion of a seat, wherein the sitting portion cover comprises;

a first cover member for covering a main part of a top surface of the sitting portion;

the fourth cover members, the fifth cover member and the sixth cover member are sewn together along bordering edges thereof; and

the bordering edge of the second cover member/the third cover members and the bordering edge of the fourth cover members/the fifth cover member are folded back to extend in a longitudinal direction along raised portions of a top surface of a sitting portion, are creased such that a bordering edge having a smaller radius of curvature has a larger number of creases than a bordering edge having a larger radius of curvature, and are attached to the remaining part of the second, third, fourth and fifth cover members with stitches while being kept curved to conform to the raised portions, so as to form a three-dimensional curved shape to conform to a top surface of a sitting portion.

2. The seat cover according to claim 1, wherein a top portion of the sitting portion cover has creases each extending in a width direction thereof, which are arranged in a plurality of columns running in a depth direction thereof at a predetermined interval.

3. The seat cover according to claim 1, wherein a top portion of the sitting portion cover has creases each extending in a depth direction thereof, which are arranged in a plurality of rows running in a width direction thereof at a predetermined interval.

4. The seat cover according to claim 1, wherein a top portion of the sitting portion cover has a plurality of air-permeable holes arranged at a predetermined interval.

5. The seat cover according to claim 1, wherein a top portion of the sitting portion cover includes a leather layer, a high density cotton layer, a low repellence sponge layer, a tricot layer and an air-permeable back layer stacked in this order from a surface for contacting a person sitting on the seat cover.

6. The seat cover according to claim 1, wherein the sitting portion cover comprises fixing means for detachably fixing the sitting portion cover to the sitting portion.

7. A seat cover, comprising:

a backrest cover for covering a backrest of a seat, wherein the backrest cover comprises;
