Abstract
Disclosed herein are a cold/warm headrest for a vehicle and a method of controlling operation thereof. It is possible to provide cold air to an occipital region, a head, and a face of a seated occupant, and to provide warmth to a neck and shoulders of the occupant, in which the trapezius muscles are located along with peripheral nerves.
Claims19
A headrest for a vehicle, comprising:
- a duct installed in the headrest, and having an inlet for introduction of air and an outlet for discharge of air toward a front in which an occupant is located;
- and
- a thermo-element installed in the duct, and having a heat absorption part and a heat radiation part.
A method of controlling operation of a headrest for a vehicle, comprising:
- checking stages of operation when a heating switch is operated, and setting a target temperature depending on the stages of operation;
- applying a voltage to a heating element, and then determining whether a temperature of the heating element reaches the target temperature, after the checking stages of operation;
- and
- controlling the heating element such that the heating element is maintained at a constant temperature by controlling application of electric power to the heating element when the temperature of the heating element reaches the target temperature, after applying a voltage to the heating element.

A method of controlling operation of a headrest for a vehicle, comprising:
- checking stages of operation when a cooling switch is operated, and setting a control strategy depending on the stages of operation;
- applying voltages to a thermo-element and a blower depending on the set control strategy, and then determining whether an interior temperature in the vehicle reaches a target temperature;
- and
- determining whether the stage of operation of the cooling switch is a low stage or a high stage when the interior temperature is determined to reach the target temperature, and controlling the interior temperature such that the interior temperature is maintained within a set temperature range by applying a hysteresis to the voltage applied to the thermo-element or the blower depending on the determined stage of operation.
