Abstract:
The present invention relates to a height control apparatus for a headrest and a chair comprising same and, in particular, comprises: an installation portion which is recessed in the rear surface of a headrest body toward the front direction; support members provided at left and right end portions of the installation portion; a height-adjusting guide block which is inserted between the rear surface of the headrest body, which corresponds to the installation portion, and the support members; and frictional force generators which are coupled to the front surfaces of a pair of protrusion ends corresponding to the left and right end portions of the height-adjusting guide block, and come into contact with the rear surface of the headrest body, which corresponds to the installation portion, so as to generate the frictional force corresponding to the reaction against the initial actuating force provided by a user. Thus, there are advantages of improving user convenience and preventing the generation of operating noise.
