Abstract

The present disclosure provides a seat heating system for a vehicle including: an exhaust gas inlet tube having one end communicating with a silencer hole formed in a muffler silencer, and the other end mounted on a vehicle body in a front and rear direction of a vehicle and connected to a seat rail coupled to a seat and an exhaust gas outlet tube having one end communicating with a muffler pipe of the rear end of the muffler silencer, and the other end connected to the seat rail, and the present disclosure may not require a seat interior hot wire of a vehicle, and implement a heating function using the waste heat of exhaust gas to heat the seat.

First claim

What is claimed is:

1. A seat heating system for a vehicle comprising:
an exhaust gas inlet tube having one end communicating with a silencer hole in a muffler silencer, and the other end mounted on a vehicle body and connected to a first seat rail coupled to a seat; and
an exhaust gas outlet tube having one end communicating with a muffler pipe of a rear end of the muffler silencer, and the other end connected to the first seat rail.

2. The seat heating system for a vehicle of claim 1 ,
wherein the first seat rail has a hollow structure.

3. The seat heating system for a vehicle of claim 1 , further comprising:
a second seat rail; and
a heat exchanging tube for connecting the first and second seat rails.

4. The seat heating system for a vehicle of claim 3 ,
wherein a plurality of heat exchanging tubes are configured.

5. The seat heating system for a vehicle of claim 4 ,
wherein openings and closings of the plurality of heat exchanging tubes are individually controlled.

6. The seat heating system for a vehicle of claim 1 , further comprising: a rotational plate mounted on the muffler silencer,
wherein the one end of the exhaust gas inlet tube is coupled through a rotational plate hole in the rotational plate to communicate with the silencer hole.

7. The seat heating system for a vehicle of claim 6 ,
wherein a degree of the communication between the exhaust gas inlet tube and the silence hole is adjusted by a rotational operation of the rotational plate.

8. The seat heating system for a vehicle of claim 7 , further comprising:
an actuator motor mounted on the muffler silencer; and
a power transfer part for transferring power by an operation of the actuator motor to the rotational plate.

9. The seat heating system for a vehicle of claim 8 ,
wherein the power transfer part comprises:
a rod connected to the actuator motor; and
a gear coupled to an end of the rod, and
wherein the rotational plate is provided with a rotational plate gear engaged with the gear.

10. The seat heating system for a vehicle of claim 1 ,
wherein the exhaust gas inlet tube and the exhaust gas outlet tube are partially provided with wrinkle tubes.

11. The seat heating system for a vehicle of claim 1 ,
wherein the other end of the exhaust gas inlet tube is mounted on the vehicle body in a front and rear direction of the vehicle.

12. A seat heating system for a vehicle comprising:
an exhaust gas inlet tube having one end communicating with a silencer hole in a muffler silencer, and the other end mounted on a vehicle body and connected to a first seat rail coupled to a seat;
an exhaust gas outlet tube having one end communicating with a muffler pipe of a rear end of the muffler silencer, and the other end connected to the first seat rail; and
a heating adjustment structure for adjusting a degree of the communication between the exhaust gas inlet tube and the silencer hole.

13. The seat heating system for a vehicle of claim 12 ,
wherein the heating adjustment structure comprises:
an actuator motor mounted on the muffler silencer;
a rotational plate mounted on the muffler silencer; and
a power transfer part for transferring power by an operation of the actuator motor to the rotational plate.

14. The seat heating system for a vehicle of claim 13 ,
wherein the one end of the exhaust gas inlet tube is coupled through a rotational plate hole in the rotational plate to communicate with the silencer hole, and
wherein the degree of the communication between the exhaust gas inlet tube and the silencer hole is adjusted by a rotational operation of the rotational plate.

15. The seat heating system for a vehicle of claim 14 ,
wherein the power transfer part comprises:
a rod connected to the actuator motor; and
a gear coupled to an end of the rod, and
wherein the rotational plate is provided with a rotational plate gear engaged with the gear.

16. The seat heating system for a vehicle of claim 12 , further comprising:
a second seat rail; and
a heat exchanging tube for connecting the first and second seat rails.

17. The seat heating system for a vehicle of claim 16 ,
wherein a plurality of heat exchanging tubes are configured.

18. The seat heating system for a vehicle of claim 12 ,
wherein the other end of the exhaust gas inlet tube is mounted on the vehicle body in a front and rear direction of a vehicle.
