Abstract

A seat air conditioning device that blows out air from a seat, supplied from an interior air conditioning unit that air-conditions a space in a passenger compartment for a vehicle, includes: a floor-side duct and a seat-side duct. The floor-side duct is disposed adjacent to a floor of a vehicle body member forming the space in the passenger compartment and is connected to the interior air conditioning unit. The air supplied from the interior air conditioning unit flows through the floor-side duct. The seat-side duct is disposed adjacent to the seat and communicates with the floor-side duct through a connecting duct. The connecting duct is configured to be deformed to follow displacement of the seat, and is arranged along a vehicle harness that connects a floor-side wiring member disposed adjacent to the floor and a seat-side wiring member disposed adjacent to the seat.

First claim

What is claimed is:

1. A seat air conditioning device that blows air, out of a seat, supplied from an interior air conditioning unit that air-conditions a space in a passenger compartment for a vehicle, the seat air conditioning device comprising:
a floor-side duct disposed adjacent to a floor of a vehicle body member forming the space in the passenger compartment and connected to the interior air conditioning unit, the air supplied from the interior air conditioning unit flowing through the floor-side duct; and
a seat-side duct disposed adjacent to the seat to communicate with the floor-side duct through a connecting duct, wherein:
the connecting duct is configured to be deformed to follow displacement of the seat;
the connecting duct is arranged along a connecting wiring member that connects a floor-side wiring member disposed adjacent to the floor and a seat-side wiring member disposed adjacent to the seat; and
when seen in a vertical direction of the vehicle, the connecting duct and the connecting wiring member are disposed so as to not overlap with each other, and a surface of the connecting duct closest to a front side of the vehicle and a surface of the connecting wiring member closest to a rear side of the vehicle face each other wherein the connecting wiring member and the connecting duct are both U-shaped in a horizontal plane of the vehicle, such that the connecting wiring member is within and offset of the connecting duct in a parallel manner toward a front of the vehicle.

2. The seat air conditioning device according to claim 1 , wherein:
a connecting portion of the connecting duct that is connected to the floor-side duct and a connecting portion of the connecting wiring member that is connected to the floor-side wiring member are disposed close to each other; and
a connecting portion of the connecting duct that is connected to the seat-side duct and a connecting portion of the connecting wiring member that is connected to the seat-side wiring member are disposed close to each other.

3. The seat air conditioning device according to claim 1 , wherein the connecting duct and the connecting wiring member are disposed in a same plane.

4. The seat air conditioning device according to claim 1 , wherein the connecting wiring member is disposed inside the connecting duct.

5. The seat air conditioning device according to claim 1 , wherein the connecting duct and the connecting wiring member are bound by a binding member.

6. The seat air conditioning device according to claim 1 , wherein a blower that blows the air from the interior air conditioning unit is provided near the floor.

7. The seat air conditioning device according to claim 1 , wherein a blower that blows the air from the interior air conditioning unit is provided near the interior air conditioning unit.

8. The seat air conditioning device according to claim 1 , wherein the connecting duct and the connecting wiring member are configured to be able to be moved while being kept parallel to each other when a position of the seat is adjusted in a front-rear direction of the vehicle.

9. The seat air conditioning device according to claim 1 , wherein the U-shape, of the connecting wiring member is smaller than the U-shape of the connecting duct, and the U-shape of the connecting wiring member is positioned on an inner side of the U-shape of the connecting duct.

10. The seat air conditioning device according to claim 1 , wherein the connecting duct and the connecting wiring member are geometrically similar to each other.

11. The seat air conditioning device according to claim 1 , wherein the surface of the connecting duct closest to the front of the vehicle and the surface of the connecting wiring member closest to the rear of the vehicle are equidistant from each other along an entire periphery thereof.

12. The seat air conditioning device according to claim 11 , wherein the connecting duct and the connecting wiring member are configured to remain equidistant from each other when a position of the seat is adjusted in a front-rear direction of the vehicle.

13. The seat air conditioning device according to claim 5 , wherein the binding member includes a first retaining portion configured to retain the connecting duct and a second retaining portion configured to retain the connecting wiring member.

14. The seat air conditioning device according to claim 2 , wherein:
the connecting portion of the connecting wiring member that is connected to the floor-side wiring member is disposed directly adjacent to an inner side of the connecting portion of the connecting duct that is connected to the floor-side duct; and
the connecting portion of the connecting wiring member that is connected to the seat-side wiring member is disposed directly adjacent to an inner side of the connecting portion of the connecting duct that is connected to the seat-side duct.
