IPC: A47C7/74
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To quickly blow out the heated or cooled air from an air blow-out port of a seat by feeding the air, of which temperature is already controlled, of a temperature controller for vehicle to an air intake port of a blower through a blow-out direction changing means with the operation of the blower, and furthermore, feeding this air through a seat temperature control means. SOLUTION: A blow-out direction changing means 53 is formed of a louver 56 for changing the direction of the air, of which temperature is already controlled, from a temperature controller 51 for vehicle and a louver driving means 57 for driving the louver on the basis of the direction change signal C from a controller 54. When a blower 12 is operated, operation signal D is sent from the blower 12 to the controller 54. When the controller 54 sends the direction change signal C to a blow-out direction changing means 53 on the basis of the operation signal D, the louver driving means 57 operates the louver 56 so as to be directed to an air intake port 11 of the blower 12. Furthermore, the air, of which temperature is already controlled, is fed through a temperature control mechanism 20 of a seat 1 so that the sufficiently heated or cooled air can be blown out of the air blow-out hole.
