The present invention relates to a ventilation seat device for a vehicle and a method for manufacturing the same, and more particularly, to a ventilation seat device for a vehicle capable of easily coupling a foam pad to a seat frame and a duct assembly, and a manufacturing method thereof.

In general, a vehicle is provided with a seat on which an occupant can sit, and the seat is composed of a seat back capable of supporting the driver's back and waist portions, and a seat cushion on which the hip portions are seated. In such a seat, when the driver sits for a long time, sweat is discharged from the buttocks, back, and waist, causing discomfort to the seated occupant.

To solve such a problem, a ventilation device that blows wind to the occupants seated on the seat is installed on the seat, and this ventilation device blows the wind through the ventilation path provided in the seat back and seat cushion, By supplying air to the area in contact with the occupant, it is possible to provide a comfortable ride in addition to a cooling function.

Meanwhile, in the process of manufacturing a conventional ventilation seat device for a vehicle, when the seat cushion is coupled to the seat frame, the seat cushion must be placed on the upper surface of the seat frame and then coupled to the seat frame and duct assembly. There is a problem in that it is difficult to check whether the seat cushion is properly coupled to the seat frame and duct assembly due to the limited view.

The matters described as the background art are only for enhancing an understanding of the background of the present invention, and should not be taken as acknowledging that they correspond to the prior art already known to those of ordinary skill in the art.
