Heating device for vehicle seat {Heating Apparatus for Car Seat}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating device for a vehicle seat, and more particularly to a heating device for a vehicle seat that provides efficient heating to a user in a limited power supply situation in a vehicle.

Most vehicles are equipped with a heater, which warms the indoor air of the winter vehicle, allowing it to operate in a warm environment. However, since the heater uses the heat of the heated engine, a predetermined time is required until the engine is heated after the vehicle is boarded, and it may also cloud the in-vehicle air and cause drowsiness when the engine is operated for a long time.

In order to assist heating devices such as a heater of a vehicle, a heating sheet using a heating wire that has a heating wire in the seat and generates power by receiving power from a battery of a vehicle has already been commercialized. The user can feel the warmth faster by receiving heat directly from the sheet (by conduction heat).

Of course, even in a vehicle that is not equipped with a heating sheet using such a heating wire, the heating sheet using the above-described heating wire is provided by separately applying a heating seat cover with a built-in heating wire to cover the seat of the vehicle and receiving power through a cigar jack socket. You can also enjoy the same effect.

However, since the heating sheet or the heating sheet cover using the conventional heating wires all use the heating wires as heating elements, too much power is instantaneously supplied for rapid temperature rise, so that they are installed at various parts of the vehicle at the same time. In the case of use, overcurrent may occur and fuse or melt may occur. Furthermore, in an environment where power consumption is extremely limited, such as an automobile, it may be difficult to use multiple thermal sheets (or thermal sheet covers).

In addition, since a heat generation method using a conventional heating wire transfers heat to a user by using heat conductivity, only a portion (thigh or the like) directly contacting the seat (or seat cover) can feel warmth, It does not affect the temperature of the room air.

The present invention has been made to solve the problems of the prior art as described above, after the initial operation to supply the total power to the bottom portion of the seat to concentrate the initial heating, and distribute the power to the bottom portion and the back portion to supply heat It is an object of the present invention to provide a heat generating device for a vehicle seat that can significantly reduce the power usage by allowing continuous heat generation.

In addition, it is another object to provide a heat generating device for a vehicle seat that can raise the indoor air temperature of the vehicle by using a woven heating element woven with carbon fiber yarns to generate radiant heat as well as conduction heat.

A vehicle seat heating device according to the present invention for achieving the above object, the bottom portion and the back portion each comprising a woven heating element a and woven heating element b to generate heat by receiving power; And a temperature controller for distributing and supplying power to the weave heating element a and the weave heating element b after supplying the entire power supplied from the vehicle to the weaving heating element a. It includes.

Here, the woven heating element a and the woven heating element b may be electrically connected in series to receive power from the temperature control unit.

In addition, the woven heating element a and the woven heating element b may be manufactured by including a plurality of carbon fiber yarns and a plurality of copper wire bands capable of supplying power in parallel to the carbon fiber yarns, respectively.

In addition, the temperature control unit connects the positive pole of the DC power supplied from the vehicle to one copper band of the copper wire band of the weaving heating element a, and the negative pole of the DC power supplied from the vehicle to the user's input. According to the present invention, the copper wire band portion of the woven heating element a may be connected to the other copper band portion or the copper wire band portion of the woven heating element b of the copper wire band portion so as to be electrically connected in series with the woven heating element a.

In addition, the temperature sensor for measuring the temperature of the heat generated in the woven heating element a; and the temperature control unit, the positive and negative poles of the DC power supplied from the vehicle, respectively, the woven heating element a Connected to one copper band part and the other copper band part of the power supply to supply the whole power to the woven heating element a, and when the temperature measured by the temperature sensor reaches a preset temperature, the power supply of the DC power supplied from the vehicle ( The pole may be connected to any one of the copper band portions of the copper band portion of the woven heating element b so as to be electrically connected to the woven heating element a in series.

According to the present invention has the following effects.

First, in the early stage of operation, the entire power is supplied to the bottom of the seat to concentrate the initial heating, and then the power is distributed to the bottom and the back part so that the heat can be continuously generated. I can heat it. Therefore, even when a plurality of vehicle seat heating devices are used in a place where the use of power is limited, such as a vehicle, there is no problem in using the power.

Second, because the woven heating element made of carbon fiber yarns is used, it not only delivers a direct thermal effect on the body in contact with the conductive heat, but also generates radiant heat, thereby increasing the indoor air temperature of the vehicle and emitting far infrared rays. Due to sterilization, deodorization, antimicrobial action can create a pleasant environment.

Third, the user can directly control the switching between the strong mode (supplying full power to the bottom) and the weak mode (distributing power to the bottom and back), but using the temperature sensor or timer function By doing so, power savings can be achieved, especially for the driver, eliminating the need to use hands to switch functions and reducing the risk of an accident due to overheating.

Fourth, when used in conjunction with the heater of the vehicle, it is possible to purify the muddy air due to the heater, even if the heater is not running can be sufficiently warm the indoor air by using the radiant heat due to the heat generated by the carbon fiber yarn, the operation of the heater This can eliminate the inconvenience of waiting for the engine to heat up.
