Abstract
Disclosed herein is an automotive headrest, which is constructed so that the automotive headrest is not tilted, but is displaced in a straight line in only one direction in a rectilinear motion, and is then returned to its original position. The automotive headrest includes a stay rod having vertical parts secured to a seat, and a horizontal part coupling the vertical parts to each other. A horizontal guide frame is secured to the horizontal part of the stay rod. A ratchet slider is movably mounted to the horizontal guide frame. A ratchet pawl locks or releases the ratchet slider. A tension spring returns the displaced ratchet slider to its original position. A ratchet spring provides tensile force to the ratchet pawl.
