PURPOSE: A headrest of a seat for a vehicle is provided to improve convenience of a passenger by supporting both sides of the head by rotating an auxiliary headrest with an inclination sensor and a control unit. CONSTITUTION: A headrest(100) of a seat for a vehicle comprises a main body(110), a pair of auxiliary headrests(120), a hinge unit, a driving unit, a link unit, an operation unit, an inclination sensor, and a control unit. The auxiliary headrest is connected to one side facing each other on both sides of the main body by a hinge. The inclination sensor senses inclination of a seatback. The control unit controls the driving unit according to an inclination value of the seatback sensed by the inclination sensor. The driving unit generates a rotatory force rotating the auxiliary headrest. |
