Seating detection step (S10) is a step of detecting a person sitting on the seat. For example, the moment the person sits on the seat, the seating sensor may be configured to transmit a seating signal to the microcomputer.

Timer operation step (S20) is a step to enable the thermal heater to operate after a suitable time by operating the timer in accordance with the detection of seating. For example, the microcomputer receiving the seating signal may be configured to start a time integration by operating a timer.

Thermal heater operation step (S30) is a step to provide the heat by operating the thermal heater. For example, when the integration time by the timer elapses for a predetermined time, the operation signal may be transmitted to the heater driving relay to heat the heated heater.

The temperature sensing step S40 is a step of sensing a temperature after a person sits in a chair.

Thermal heater control step (S50) is a step for maintaining the temperature of the backrest by optimizing the temperature of the backrest by checking the temperature of the backrest and ON / OFF the heater according to the identified temperature. For example, if the temperature sensor detects the temperature of the backrest and recognizes that the temperature exceeds the preset maximum temperature, the microcomputer turns off the heat heater. It may be configured to repeat the process of turning on the heater (ON).

The back contact detecting step (S60) is a step of detecting whether the back part contacts the back when a person sits on a chair and leans back. For example, the instantaneous contact sensor may be configured to transmit a back contact signal to the microcomputer at the moment the person leans back on the back.

Timer and massage motor operation step (S70) is a step to enable the massage motor to operate after a suitable time by operating the timer in response to the back contact. For example, the microcomputer receiving the back contact signal may operate the timer to start integration of the back contact time and at the same time operate the massage motor provided in the backrest to vibrate.

Alternatively, the massage motor may be configured to perform a massage after a certain time has passed after sitting. In this case, the time until the massage motor is operated after sitting may be differently set for each individual. For example, the massage motor may be configured to vibrate when the time accumulated by the timer exceeds a preset time.

The massage motor stop step (S80) is a step of automatically stopping the massage motor after performing massage for a predetermined time. For example, the vibration massage may be automatically stopped when a predetermined time elapses after the vibration massage starts.

While the seating detection sensor recognizes the seat as a timer, it may be configured to repeat the timer operation step (S20), the heat heater operation step (S30), the temperature detection step (S40) and the heat heater control step (S50). That is, when it is detected that the user continues to be seated, the heating heater may be operated after a predetermined time elapses and the heating heater may be stopped when the predetermined heating time elapses.

In addition, while the back contact detection sensor recognizes the back contact, the timer / massage motor operation step (S70) and the massage motor stop step (S80) can be configured to be repeated.
