<p>The present invention relates to an elevation guide assembly of a headrest unit capable of simplifying the assembly structure of an elevation guide assembled to an upper frame, thereby improving an assembly property of the elevation guide and improving the degree of design freedom of the components to assemble the elevation guide. According to the present invention for the above, an elevation guide assembly of a headrest unit comprises: an upper frame installed in the upper side of a seatback, having a first fastening part on the bottom thereof; and an elevation guide coupled to the upper frame having a second fastening part formed on the end thereof corresponding to the first fastening part. According to the present invention, the second fastening part on the top of the elevation guide can simply be assembled and fastened to the first fastening part on the bottom of the upper frame such that the elevation guide can be mounted and be used without a new manufacture of the elevation guide even if a step height between the top and the bottom of the upper frame is changed; thereby improving the assembly property of the elevation guide and the degree of design freedom of the upper frame and the elevation guide.</p> |
