The present invention relates to a vehicle seat using a ventilation system integrated seat foam pad, and at the same time the backboard so that shaping of the fan housing to the inside back pad of the seat back integrally to the assembly process reduced by installing a ventilation fan to be fixed to the fan housing ventilation systems integrated to the back and to secure a space between the pad so that the anti-ventilation fan and the interference of the wooden boards, to form a guide groove for guiding the airflow to the front of the back pad so that the whole ventilation made on the front of the seat back to provide a vehicle seat with the seat foam pad.
The invention, which back pad according to the vehicle seat equipped with a ventilation fan, before and after the vent holes are formed in a direction for accomplish the above object; The fan housing that is integrally molded on the inside of the back pad so as to position the vent holes of the back pad; Ventilation fan is installed in the fan housing; The protective cover being coupled to the fan housing, which protects the ventilation fan; It said aeration holes before, is inserted into the rear vent to occur while mash to bridge the vent hole; that is configured, including as a technological base.
