ABSTRACT:
A headrest for seats for use in vehicles has a fixed frame fixedly secured to the upper ends of stays supported on a seat back, two right and left movable frames secured to a panel of the headrest, and two pairs of parallel links connecting the fixed and movable frames; a first pair connecting the right movable frame to the right end portion of the fixed frame, and a second pair connecting the left movable frame to the left end portion of the fixed frame. One of the first pair of links is connected with one of the second pair via a connecting portion. With such structure, the headrest can be moved back and forth with little change in height, and, since there are no moving parts present in all portions of the headrest except in the two end portions of the fixed frame, a throughbore can be provided in the central portion of the headrest.
