Abstract
A guide sleeve receives and supports a guide post of a bead restraint within a seat back frame of a seat assembly. The guide sleeve includes a body extending between opposite upper and lower ends. A bare defined by cylindrical inner walls extends longitudinally through the guide sleeve for slidably receiving the guide post therethrough for allowing selective adjustment of the head restraint relative to the seat back between a plurality of head supporting positions. A plurality of rings project outwardly from the body and are deformable against the seat back frame during insertion of the guide sleeve into a hole or tube formed in the seat back frame for creating a interference fit between the guide sleeve and the seat back frame 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.
