Abstract

A vehicle seat including a three-dimensional woven knitted fabric including a surface-layer-side base fabric, a back-layer-side base fabric, and an intermediate layer that three-dimensionally connects the surface-layer-side base fabric and the back-layer-side base fabric, the three-dimensional woven knitted fabric being tightly stretched on a seat frame by a locking member provided to an end portion thereof to form a seat surface, wherein an edge portion of the three-dimensional woven knitted fabric has a single-layer structure, which includes only the back-layer-side base fabric among the surface-layer-side base fabric, the back-layer-side base fabric and the intermediate layer, and wherein the locking member is provided to an end portion of the back-layer-side base fabric.

Claims

1. A vehicle seat including a three-dimensional woven knitted fabric including a surface-layer-side base fabric, a back-layer-side base fabric, and an intermediate layer that three-dimensionally connects the surface-layer-side base fabric and the back-layer-side base fabric, the three-dimensional woven knitted fabric being tightly stretched on a seat frame by a locking member provided to an end portion thereof to form a seat surface,

wherein an edge portion of the three-dimensional woven knitted fabric has a single-layer structure, which includes only the back-layer-side base fabric among the surface-layer-side base fabric, the back-layer-side base fabric and the intermediate layer, and

wherein the locking member is provided to an end portion of the back-layer-side base fabric.

2. A vehicle seat according to claim 1,

wherein the surface-layer-side base fabric has a higher elasticity than that of the back-layer-side base fabric.

3. A vehicle seat including a three-dimensional woven knitted fabric having a surface-layer-side base fabric, a back-layer-side base fabric, and an intermediate layer that three-dimensionally connects the surface-layer-side base fabric and the back-layer-side base fabric, the three-dimensional woven knitted fabric being tightly stretched on a seat frame by a locking member provided to an end portion thereof to form a seat surface,

wherein an edge portion of the three-dimensional woven knitted fabric has a double-layered structure, which includes the surface-layer-side base fabric and the back-layer-side base fabric which are directly laminated without the intermediate layer therebetween,

wherein the locking member is provided to an end portion of the edge portion having the double-layered structure, and

wherein the surface-layer-side base fabric has a higher elasticity than that of the back-layer-side base fabric.

4. A vehicle seat comprising:

a seat frame;

a woven knitted fabric including,

a first base fabric,

a second base fabric, and

an intermediate layer; and

a locking member that tightly stretches the woven knitted fabric to the seat frame to form a seat surface,

wherein the first base fabric, the intermediate layer and the second base fabric are laminated in this order in a first direction perpendicular to the seat surface,

wherein a portion of the second base fabric extends further outwards in a second direction parallel to the seat surface than the first base fabric and the intermediate layer, and

wherein the locking member is provided to the portion of the second base fabric that extends further outwards in the second direction.
