Abstract
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.
