Abstract

Provided is a seat which achieves reduction in wrinkling and looseness while maintaining flexibility of a cover made of leather. The seat includes: a cover made of leather and covering a pad; and a base fabric adhered to the cover. The base fabric is an woven fabric including a plurality of first threads running in a predetermined direction and a plurality of second threads running in a direction intersecting the predetermined direction. The first threads and the second threads are woven in a zigzag manner to planarly fill a surface of the base fabric with polygonal space parts defined by the first threads and the second threads.

First claim

The invention claimed is:

1. A seat comprising:
a pad;
a cover made of leather and covering a surface of the pad; and
a base fabric adhered to a surface of the cover that faces the pad, wherein
the base fabric includes a plurality of first linear members running in a predetermined direction and a plurality of second linear members running in a direction intersecting the predetermined direction,
the first linear members and the second linear members being connected to each other in a zigzag manner to planarly fill a surface of the base fabric with polygonal space parts defined by the first linear members and the second linear members, and
each of the polygonal space parts is defined by a portion of the first linear member having two or more corners and a portion of the second linear member having two or more corners.

2. The seat according to claim 1 , wherein
the polygonal space part has a hexagonal shape.

3. The seat according to claim 1 , wherein
the polygonal space part has six side sections and is deformable into a hexagonal shape when the base fabric is pulled.

4. The seat according to claim 1 , wherein
each of the polygonal space parts has an octagonal space and a quadrangular space in connection.

5. The seat according to claim 1 , wherein
one first linear member twistedly joins another first linear member or one second linear member twistedly joins another second linear member.

6. The seat according to claim 1 , wherein
the base fabric further includes a connecting member that connects the first linear members to each other at a distance therebetween or connects the second linear members to each other at a distance therebetween.

7. The seat according to claim 1 , wherein
a direction in which the first linear members run and a direction in which the second linear members run perpendicularly intersect each other.

8. The seat according to claim 1 , wherein
the first linear members and the second linear members are made of thread, and
the base fabric is a woven fabric including the first linear members and the second linear members,
the first linear members and the second linear members being woven with one another in a zigzag manner to planarly fill the surface of the base fabric with the polygonal space parts defined by the first linear members and the second linear members.

9. The seat according to claim 1 , wherein
the base fabric is a knitted fabric knitted with at least one yarn so as to combine the first linear members and the second linear members,
the first linear members and the second linear members being connected to each other in a zigzag manner to planarly fill the surface of the base fabric with the polygonal space parts defined by the first linear members and the second linear members to form the knitted fabric.
