Abstract

An air-conditioning device for a vehicle seat has a seat, an air conditioning duct, a floor-side connection part, a seat-side connection part, and a connection duct. A position of the seat is adjusted in a front-rear direction. The air conditioning duct guides air, which is supplied from an interior air-conditioning unit, to a lower side of the seat. The floor-side connection part is provided in a vehicle-compartment floor on the lower side of the seat and connects to a downstream side of the air conditioning duct in an air flow direction. The seat-side connection part is provided in a seat bottom surface. The connection duct has one end portion connecting to the floor-side connection part and an other end portion connecting to the seat-side connection part. The seat-side connection part transfers across the floor-side connection part in the front-rear direction when a position of the seat is adjusted in the front-rear direction. The connection duct is deformable and stretchable. The floor-side connection part and the seat-side connection part are arranged at different positions in a left-right direction when viewed from a front side of a vehicle.

First claim

What is claimed is:

1 . An air-conditioning device for a vehicle seat comprising:
a seat in which an air passage is formed, the seat of which position is adjustable in a front-rear direction of a vehicle; an air conditioning duct connected to an interior air-conditioning unit that air-conditions an interior space of a vehicle compartment, the air conditioning duct that guides air, which is supplied from the interior air-conditioning unit, to a lower side of the seat; a floor-side connection part that is provided in a vehicle-compartment floor on the lower side of the seat and connects to a downstream side of the air conditioning duct in an air flow direction; a seat-side connection part that is provided in a seat bottom surface of the seat and connects to the air passage; and a connection duct that guides air flowing in the air conditioning duct to the air passage through both the floor-side connection part and the seat-side connection part, wherein the connection duct is deformable and stretchable, and the floor-side connection part and the seat-side connection part are arranged to avoid overlapping with each other in an upper-lower direction of the vehicle when the seat is moved in the front-rear direction.

2 . The air-conditioning device for a vehicle seat according to claim 1 , wherein
the floor-side connection part and the seat-side connection part are arranged at different positions in a left-right direction of the vehicle.

3 . The air-conditioning device for a vehicle seat according to claim 2 , wherein
the floor-side connection part and the seat-side connection part are arranged to be coincident with each other in the front-rear direction of the vehicle when the seat is located at a specified position in a range in which a position of the seat is adjustable in the front-rear direction of the vehicle.

4 . The air-conditioning device for a vehicle seat according to claim 3 , wherein
the floor-side connection part and the seat-side connection part are arranged such that the seat-side connection part transfers across the floor-side connection part in the front-rear direction of the vehicle when the seat is moved in the front-rear direction of the vehicle.

5 . The air-conditioning device for a vehicle seat according to claim 1 , wherein
the floor-side connection part and the seat-side connection part are arranged such that the seat-side connection part is located on a rear side of the floor-side connection part in the front-rear direction of the vehicle when the seat is located at a foremost position in a range in which a position of the seat is adjustable in the front-rear direction of the vehicle.

6 . The air-conditioning device for a vehicle seat according to claim 1 , wherein
the floor-side connection part and the seat-side connection part are arranged such that the seat-side connection part is located on a front side of the floor-side connection part in the front-rear direction of the vehicle when the seat is located at a rearmost position in a range in which a position of the seat is adjustable in the front-rear direction of the vehicle.

7 . The air-conditioning device for a vehicle seat according to claim 1 , wherein
the seat is provided with two seat rails adjusting a position of the seat in the front-rear direction of the vehicle, and the two seat rails are respectively provided in both end portions of the seat bottom surface in a left-right direction of the vehicle, and the connection duct has one end portion connecting to the floor-side connection part and an other end portion connecting to the seat-side connection part, and both the one end portion and the other end portion are arranged on a side that is adjacent to one seat rail of the two seat rails.

8 . The air-conditioning device for a vehicle seat according to claim 7 , wherein
the two seat rails are fixed to a fixed member provided on a vehicle-body side, and the one end portion of the connection duct is fixed to a bracket that is provided with the one seat rail, and the connection duct and the floor-side connection part are connected to each other by pressing the bracket to the vehicle-compartment floor when the two seat rails are fixed to the fixed member.

9 . The air-conditioning device for a vehicle seat according to claim 1 , further comprising
a blower that is arranged below the vehicle-compartment floor and causes an air flow, wherein the air conditioning duct has a downstream end portion that connects to the floor-side connection part through the blower.
