Vehicle seat with cooling/heating device
First Claim
1. A vehicle seat including a seat cushion and a seat back with a cooling/heating device, the vehicle seat comprising:
- electric fans respectively equipped in a lower portion of the seat cushion and a rear portion of the seat back to intake indoor air within a vehicle into the seat cushion and the seat back;
cushion members respectively provided in the seat cushion and the seat back and formed with air-supply pathways to supply air induced from the seat cushion and the seat back to an upper portion of the seat cushion and to a front portion of the seat back;
air-spreading layers respectively layered on an upper portion of the cushion member provided in the seat cushion and on a front portion of the cushion member provided in the seat back to spread air induced through the air-supply pathways by an area corresponding to at least an area of the vehicle seat contacting the hip and the back of a person seated in the vehicle;
heating pads respectively layered on the air-spreading layers, with a heating line disposed therein to generate heat when electric power is applied to the heating line, and with a plurality of ventilation holes punctured through each of the heating pads between serpentine sections of the heating line along the heating line; and
seat covers respectively layered on the heating pads and having a plurality of air discharge openings formed on the surface of each of the seat covers, through which air supplied through the air-spreading layers and the ventilation holes of the heating pads is discharged.
