Abstract

It is an object to provide a seat of which a seating comfort can be improved. The seat includes a seat cushion pad having an air passage formed inside and an air vent formed at an upper surface thereof, and is configured to allow air in the air passage to blow out through the air vent, wherein the seat cushion pad includes a pad body and a cover member which is disposed over the pad body to form the air passage between the pad body and the cover member and in which the air vent is formed, and a front end portion of the cover member extends downward over a front end portion of the pad body.

Claims

1. A seat comprising:

a pad having an air passage formed inside and an air vent formed at an upper surface thereof, the seat being configured to allow air to flow through the air passage and the air vent, the pad including a pad body and a cover member, the cover member being disposed over the pad body to form the air passage between the pad body and the cover member, the air vent being formed in the cover member;

an outer covering provided over the pad, the outer covering having a portion capable of being tucked in the pad; and

a covering attachment wire with which the portion of the outer covering capable of being tucked in the pad is engageable, the covering attachment wire being provided in the pad,

wherein the covering attachment wire defines a horizontal plane, and the air passage intersects the horizontal plane.

2. The seat according to claim 1, wherein the pad body and the cover member have a body-side air-passage depression and a cover-side air passage depression, respectively, which are combined to form the air passage, and

wherein the covering attachment wire is located in a position below an upper surface of the cover-side air-passage depression and above a bottom surface of the body-side air-passage depression.

3. The seat according to claim 1, wherein the pad has a tuck-in groove along which the covering attachment wire is provided, and

wherein a bottom surface of the tuck-in groove defines a horizontal plane, and the air passage intersects the horizontal plane.

4. The seat according to claim 3, wherein the pad body and the cover member have a body-side air-passage depression and a cover-side air passage depression, respectively, which are combined to form the air passage, and

wherein the bottom surface of the tuck-in groove is located in a position below an upper surface of the cover-side air-passage depression and above a bottom surface of the body-side air-passage depression.

5. The seat according to claim 1, further comprising an engageable portion provided at the portion of the outer covering to be tucked in the pad, the engageable portion being engageable with the covering attachment wire,

wherein the engageable portion defines a horizontal plane, and the air passage intersects the horizontal plane.

6. The seat according to claim 1, wherein the covering attachment wire defines a horizontal plane, and the cover member intersects the horizontal plane.

7. The seat according to claim 1, wherein the pad has a tuck-in groove along which the covering attachment wire is provided, and

wherein a lateral width of the tuck-in groove is narrower than a lateral width of the air vent.

8. The seat according to claim 1, wherein the pad has a tuck-in groove along which the covering attachment wire is provided,

wherein the pad body has a body-side air-passage depression which forms the air passage, and

wherein a vertical distance between a bottom surface of the tuck-in groove and an undersurface of the pad is shorter than a vertical distance between a bottom surface of the body-side air-passage depression and the undersurface of the pad.

9. The seat according to claim 1, wherein the pad body includes left and right bulging portions provided at left and right sides of the cover member and configured to bulge upward beyond an upper surface of the cover member,

wherein a lateral distance between the covering attachment wire and a laterally outer surface of a bulging portion adjacent the covering attachment wire is longer than a lateral distance between the covering attachment wire and a side surface of the air passage closer to the covering attachment wire.

10. A seat comprising:

a pad having an air passage formed inside and an air vent formed at an upper surface thereof, the seat being configured to allow air to flow through the air passage and the air vent, the pad including a pad body and a cover member, the cover member being disposed over the pad body to form the air passage between the pad body and the cover member, the air vent being formed in the cover member;

an outer covering provided over the pad, the outer covering having a portion capable of being tucked in the pad; and

a covering attachment wire with which the portion of the outer covering capable of being tucked in the pad is engageable, the covering attachment wire being provided in the pad,

wherein the covering attachment wire is located at a depth that is between a depth of a top of the air passage and a depth of a bottom of the air passage.

11. The seat according to claim 10, wherein the pad body and the cover member have a body-side air-passage depression and a cover-side air passage depression, respectively, which are combined to form the air passage, and

wherein the covering attachment wire is located in a position below an upper surface of the cover-side air-passage depression and above a bottom surface of the body-side air-passage depression.

12. The seat according to claim 10, wherein the pad has a tuck-in groove along which the covering attachment wire is provided, and

wherein a bottom surface of the tuck-in groove is located at a depth that is between a depth of a top of the air passage and a depth of a bottom of the air passage.

13. The seat according to claim 12, wherein the pad body and the cover member have a body-side air-passage depression and a cover-side air passage depression, respectively, which are combined to form the air passage, and

wherein the bottom surface of the tuck-in groove is located in a position below an upper surface of the cover-side air-passage depression and above a bottom surface of the body-side air-passage depression.

14. The seat according to claim 10, further comprising an engageable portion provided at the portion of the outer covering to be tucked in the pad, the engageable portion being engageable with the covering attachment wire,

wherein the engageable portion is located at a depth that is between a depth of a top of the air passage and a depth of a bottom of the air passage.

15. The seat according to claim 10, wherein the covering attachment wire and the cover member are located at a same depth.

16. The seat according to claim 10, wherein the pad has a tuck-in groove along which the covering attachment wire is provided, and

wherein a lateral width of the tuck-in groove is narrower than a lateral width of the air vent.

17. The seat according to claim 10, wherein the pad has a tuck-in groove along which the covering attachment wire is provided,

wherein the pad body has a body-side air-passage depression which forms the air passage, and

wherein a vertical distance between a bottom surface of the tuck-in groove and an undersurface of the pad is shorter than a vertical distance between a bottom surface of the body-side air-passage depression and the undersurface of the pad.

18. The seat according to claim 10, wherein the pad body includes left and right bulging portions provided at left and right sides of the cover member and configured to bulge upward beyond an upper surface of the cover member,

wherein a lateral distance between the covering attachment wire and a laterally outer surface of a bulging portion adjacent the covering attachment wire is longer than a lateral distance between the covering attachment wire and a side surface of the air passage closer to the covering attachment wire.
