<p>The present invention relates to a headrest having a rotary wing. The headrest includes a rotary shaft installed in a seat; a wing unit having a outer casing for receiving the rotary shaft therein; a locking unit for locking the wing unit to the seat; and a return spring for returning the wing unit to an original position of the wing unit. The headrest has a simple construction for rotating the wing unit, which thus reduces the production cost of the headrest .</p> |
