Abstract

A vehicle seat including a seat pad including a flow channel portion, a seat cover covering the seat pad and having breathability, a functional member disposed between the seat pad and the seat cover and having breathability, and a blowing member configured to blow the gas into or out of the seat through the flow channel portion of the seat pad and the seat cover along a flow path, wherein the functional member is integrated with any one of the seat pad and the seat cover with an adhesive portion, which has poorer breathability than the seat cover and the functional member, interposed therebetween, and wherein the adhesive portion includes a passage portion through which the gas is configured to pass, and the passage portion is disposed in the flow path of the gas.

First claim

What is claimed is:

1. A vehicle seat comprising:
a seat pad forming an outer shape of the seat, configured to elastically support an occupant, and including a flow channel portion through which gas is configured to pass;
a seat cover covering the seat pad and having breathability;
a functional member disposed between the seat pad and the seat cover and having breathability; and
a blowing member configured to feed and suction gas, wherein
the blowing member is configured to blow the gas into or out of the seat through the flow channel portion of the seat pad and the seat cover along a flow path,
the functional member is integrated with any one of the seat pad and the seat cover with an adhesive portion, which has poorer breathability than the seat cover and the functional member, the adhesive portion being interposed between the seat cover and the functional member, and
the adhesive portion includes a passage portion through which the gas is configured to pass, and the passage portion is disposed in the flow path of the gas.

2. The vehicle seat according to claim 1 , wherein
the seat cover includes:
a first part having breathability and forming a seating surface; and
a second part stacked on a rear surface side of the first part facing the functional member and being poorer in breathability than the first part, and

the second part includes an opening for exposing the first part, and the opening is disposed in the flow path of the gas.

3. The vehicle seat according to claim 2 , wherein
the passage portion and the opening are disposed opposite to each other and the passage portion covers the entire opening.

4. The vehicle seat according to claim 2 , wherein
the opening includes a first opening and a second opening, and
the passage portion and the first and second openings are disposed opposite to each other and the passage portion covers the first and second openings.

5. The vehicle seat according to claim 1 , wherein
the passage portion is a through-hole.

6. The vehicle seat according to claim 1 , wherein
the functional member is a heater member.

7. The vehicle seat according to claim 1 , wherein
the seat cover includes:
a first part having breathability and having a seating surface; and
a second part stacked on a rear surface of the first part facing the functional member and being poorer in breathability than the first part, wherein

the second part includes an opening for exposing the first part, and the opening is disposed in the flow path of the gas, and
the first part and the second part are in direct contact with each other.

8. A vehicle seat comprising:
a seat pad including a first through-hole penetrating the seat pad in a thickness direction of the seat pad;
a seat cover covering the seat pad and having breathability;
a functional member disposed between the seat pad and the seat cover in the thickness direction and having breathability;
an adhesive portion by which the functional member is integrated with any one of the seat pad and the seat cover, the adhesive portion having poorer breathability than the seat cover and the functional member and including a second through-hole penetrating the adhesive portion in the thickness direction; and
a blowing member communicating with the first through-hole and configured to feed and suction gas, wherein
the first through-hole and the second through-hole overlap with each other in the thickness direction, and
the adhesive portion is interposed between the seat cover and the functional member.

9. The vehicle seat according to claim 8 , wherein
the seat cover includes:
a first part having breathability and having a seating surface; and
a second part stacked on a rear surface of the first part which is opposite to the seating surface and being poorer in breathability than the first part,

the second part includes an opening for exposing the first part, and
the opening overlaps with the first through-hole and the second through-hole in the thickness direction.

10. The vehicle seat according to claim 9 , wherein
the entire opening overlaps with the second through-hole in the thickness direction.

11. The vehicle seat according to claim 8 ,
wherein the second through-hole is larger than the first through-hole.

12. The vehicle seat according to claim 8 , wherein
the seat cover includes:
a first part having breathability and having a seating surface; and
a second part stacked on a rear surface of the first part which is opposite to the seating surface and being poorer in breathability than the first part, wherein

the second part includes an opening for exposing the first part,
the opening overlaps with the first through-hole and the second through-hole in the thickness direction, and
the first part and the second part are in direct contact with each other.
