Abstract

A seat with a warmer may include a heating unit mounted on a rear side of a seat back and radiating heat toward a rear seat; an air duct disposed close to the heating unit on the seat back, extending up and down on the seat back, and passing air therein, and a blowing unit disposed in the air duct generating a sucking force in the air duct so that air heated by the heating unit flows into the air duct, and sending out the heated air in the air duct to a floor under the rear seat.

First claim

What is claimed is:

1. A seat apparatus with a warmer, comprising:
a heating unit mounted on a rear side of a seat back and radiating heat toward a rear seat;
an air duct disposed close to the heating unit on the seat back, extending up and down on the seat back, and passing air therein; and
a blowing unit disposed in the air duct generating a sucking force in the air duct so that air heated by the heating unit flows into the air duct, and sending out the heated air in the air duct to a floor under the rear seat,
wherein the air duct includes a horizontal duct horizontally extending over the heating unit and a vertical duct extending downward from the horizontal duct, and the blowing unit is disposed at a lower end of the vertical duct, and
wherein air intake holes are formed through a bottom of the horizontal duct of the air duct and the vertical duct is disposed across a center of the heating unit from a center of the horizontal duct.

2. A seat apparatus with a warmer, comprising:
a heating unit mounted on a rear side of a seat back and radiating heat toward a rear seat;
an air duct disposed close to the heating unit on the seat back, extending up and down on the seat back, and passing air therein; and
a blowing unit disposed in the air duct generating a sucking force in the air duct so that air heated by the heating unit flows into the air duct, and sending out the heated air in the air duct to a floor under the rear seat,
wherein the air duct includes a horizontal duct horizontally extending over the heating unit and a vertical duct extending downward from the horizontal duct, and the blowing unit is disposed at a lower end of the vertical duct, and
wherein the horizontal duct of the air duct is symmetrically divided into two parts at left and right sides from a center of the heating unit and has air intake holes formed through a bottom of the horizontal duct, while the vertical ducts are connected to the divided horizontal ducts, respectively, and disposed symmetrically at both sides of the heating unit.

3. A seat apparatus with a warmer, comprising:
a heating unit mounted on a rear side of a seat back and radiating heat toward a rear seat;
an air duct disposed close to the heating unit on the seat back, extending up and down on the seat back, and passing air therein; and
a blowing unit disposed in the air duct generating a sucking force in the air duct so that air heated by the heating unit flows into the air duct, and sending out the heated air in the air duct to a floor under the rear seat,
wherein the air duct includes a horizontal duct horizontally extending over the heating unit and a vertical duct extending downward from the horizontal duct, and the blowing unit is disposed at a lower end of the vertical duct, and
wherein the air duct vertically extends across a center of the heating unit and has air intake holes at both sides and the blowing unit is disposed at a lower end of the air duct.

4. A seat apparatus with a warmer, comprising:
a heating unit mounted on a rear side of a seat back and radiating heat toward a rear seat;
an air duct disposed close to the heating unit on the seat back, extending up and down on the seat back, and passing air therein; and
a blowing unit disposed in the air duct generating a sucking force in the air duct so that air heated by the heating unit flows into the air duct, and sending out the heated air in the air duct to a floor under the rear seat,
wherein the air duct includes a horizontal duct horizontally extending over the heating unit and a vertical duct extending downward from the horizontal duct, and the blowing unit is disposed at a lower end of the vertical duct, and
wherein a plurality of air ducts extends vertically and symmetrically at both sides of the heating unit, air intake holes are formed at sides facing each other of the air ducts, and the blowing unit is disposed at lower ends of the air ducts.
