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.
Claims4
A vehicle seat including a three-dimensional woven knitted fabric, the three-dimensional woven knitted fabric comprising:
- a surface-layer-side base fabric;
- a back-layer-side base fabric;
- and
- an intermediate layer that is disposed between and 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 define 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.
A vehicle seat including a three-dimensional woven knitted fabric, the three-dimensional woven knitted fabric comprising:
- a surface-layer-side base fabric;
- a back-layer-side base fabric;
- and
- an intermediate layer that is disposed between and 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 define 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 an elasticity that is higher than an elasticity of the back-layer-side base fabric.
A vehicle seat comprising:
- a seat frame;
- a woven knitted fabric including:
- a first base fabric;
- a second base fabric;
- and
- an intermediate layer that is disposed between the first base fabric and the second base fabric;
- and
- a locking member that tightly stretches the woven knitted fabric to the seat frame to define 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.
