PURPOSE: A head restraint with vent holes is provided to keep a fresh condition even though the back of passenger's head is left on the head restraint for hours. CONSTITUTION: A head restraint(1) with vent holes comprises a mounting groove(30), a first vent hole part(10), and a second vent hole part(20). The mounting groove is formed in the head restraint so that the back of passenger's head can be settled in the center thereof. The first vent hole part is formed in the mounting groove. The second vent hole part is respectively formed in the left and right side of the mounting groove. The first and second vent holes are depressed in a semi cylinder shape from the top to the bottom of the head restraint. The first vent hole is formed with greater width and depth than the second vent hole. |
