<p>A guide sleeve (20) for receiving and supporting a guide post (18) of a head restraint (16) within a seat back frame (17) of a seat assembly. The guide sleeve (20) includes a body (22) extending between opposite upper (24) and lower ends (26). A bore (28) defined by cylindrical inner walls (30) extends longitudinally through the guide sleeve (20) for slidably receiving the guid e post (18) therethrough for allowing selective adjustment of the head restrai nt (16) relative to the seat back between a plurality of head supporting positions. A plurality of rings (34) project outwardly from the body (22) an d are deformable against the seat back frame during insertion of the guide sleeve (20) into a hole or tube (17) formed in the seat back frame for creating an interference fit between the guide sleeve and the seat back fram e without deforming the bore, and thereby, not increasing efforts required to slide the guide post through the bore during movement of the head restraint between the plurality of head supporting positions.</p> |
