The reason for limiting the average particle diameter of the lower cork layer 121 is first, the purpose of maximally suppressing the gap between the cork particles in order to prevent heat loss in the heating member 130, and second, the user This is for the purpose of securing strength to support the pressure applied when sitting.

If the average particle diameter is less than 1mm, it is difficult to process, and if it is more than 4mm, the gaps between the non-uniform cork particles increase and increase, resulting in heat loss, and the power to support the pressure when the user is sitting is weak. A turn-off may occur.

The reason for limiting the average particle diameter (5 to 10 mm) of the upper cork layer 123 is to provide cushioning and comfort since the upper cork layer 123 corresponds to the seating portion. That is, in the case of having the above-described average particle diameter, pores (gaps) are secured between the cork particles, thereby adding pores to the elasticity of the cork itself, thereby increasing cushioning and comfort. In addition, the gap between the cork particles serves as a heat passage, and a lot of heat is emitted through the upper cork layer 123 , thereby increasing the heating effect.

The heat shield layer 122 is interposed between the lower cork layer 121 and the upper cork layer 123 , and the heat generated from the heating member 130 positioned above the heat shield layer 122 leaks downward. In addition to blocking the heat, it plays a role in concentrating the heat to the upper part. Preferably, the heat shield layer 122 is made of an aluminum (silver foil) material.

The heating member 130 serves to generate heating heat, and may be installed between the upper cork layer 123 and the heat shield layer 122 .

The carbon strip 132 acts to prevent excessive heat generation by increasing the resistance value when the ambient temperature increases. In this embodiment, the carbon strip is made of polyethylene resin or acrylic resin, carbon particles, and PTC efficiency. A mixed composition of a ceramic hollow body for improvement and titanium dioxide fine particles for durability enhancement is achieved.

A silver paste material may be used for the vertical electrode 133 and the horizontal electrode 134 in this embodiment.

According to this configuration, when the external temperature data transmitted from the external temperature sensor 161 is higher than the set temperature, the control unit 150 controls the heating member 130 to be turned off or controls the heating temperature to be lowered, and external temperature data When is lower than the set temperature, temperature control to increase the heating temperature of the heating member 130 is automatically performed.

In addition, the present invention may further include a heating member temperature sensor 162 that measures the temperature of the heating member 130 in real time and transmits it to the control unit 150 . Therefore, when the heating member 130 is abnormally overheated, the heating member temperature sensor 162 detects it and transmits it to the control unit 150, the control unit blocks the power supplied to the heating member 150, thereby preventing a fire in advance. have.

In addition, the present invention may further include a humidity sensor 163 that senses the humidity outside the bus platform and transmits it to the controller 150 . When the high temperature and high humidity climate continues in the hot season, there may be a damp feeling when seated in the upper cork layer 123, so when the humidity sensor 163 senses the external humidity and the humidity is above the appropriate line, the control unit 150 In spite of this, the heating member 150 may be temporarily operated.

In addition, the present invention may further include a user recognition sensor 164 connected to the control unit 150 so that the heating member 150 is selectively operated only when the user is seated on the upper cork layer 123 .
