A seat air conditioning unit includes a seat defining an air passage in a seat member and a blower unit for blowing air into the air passage. The air passage includes an air introduction passage communicating with the blower unit, air distribution passages formed on a surface of a main pad of the seat member adjacent to a sub pad and through holes formed in the sub pad at portions corresponding to the air distribution passages. The air distribution passages extend from the air introduction passage toward the front and rear ends or the top and bottom ends of the seat. The through holes have openings on a surface of the sub pad adjacent to a cover. A dimension of each opening is greater than a dimension of the air distribution passage in a direction substantially perpendicular to a longitudinal direction of the air distribution passage.

1. Field of the Invention
The present invention relates to a seat air-conditioning unit for a vehicle, which supplies conditioned air to a seat of the vehicle.
2. Background of the Invention
Other objects, features and advantages of the present invention will become more apparent from the following detailed description made with reference to the accompanying drawings, in which like parts are designated by like reference numbers and in which:
FIG. 1 is a plan view of a seat for explaining an air passage of a seat air conditioning unit for a vehicle according to an embodiment of the present invention;
FIG. 2 is a cross-sectional view of the seat air conditioning unit taken along line II—II in FIG. 1; and
An embodiment of the present invention will be described hereinafter with reference to the drawings.
As shown in FIGS. 1 and 2, a seat air conditioning unit 100 for a vehicle includes a seat 200 and a blower unit 300. The seat 200 includes a seat cushion (seat bottom) 200a for supporting a seat user's hip and a backrest (seat back) 200b for supporting the user's back. Each of the seat cushion 200a and the backrest 200b has a seat member 220 and a cover (seat surface member) 210 covering the seat member 220.
The cover 210 is used to enhance appearance and texture of the seat 200 and is for example made of fabrics having air permeability. When the fabric, the surface of which is coated with a backing material (e.g. resin) to avoid removal of fibers, is used, foaming process is performed to the backing material to provide air permeability. Alternatively, the cover 200 can be made of non-woven cloth or leather. In this case, a plurality of ventilation holes is formed to provide air permeability.
