ABSTRACT:
In a seat air conditioning unit for a vehicle seat constructed with a seat cushion and a seat back, when a seat air conditioning operation is performed in a cooling operation of a passenger compartment, a cooling capacity of cool air blown from the seat back is set smaller than a cooling capacity of cool air blown from these at cushion while a passenger sits on the vehicle seat. Further, the cooling capacity of cool air blown from a lower portion of the seat back can be set smaller than the cooling capacity of an upper portion of the seat back. Accordingly, even when the cooling operation is continued for a long time while the seat air conditioning operation is performed, the waist portion of the passenger can be prevented from being excessively cooled.
