Adjustable headrest

An adjusting headrest for a vehicle seat back having an apertured mounting bracket comprising:

• a molded plastic guide adapted for insertion through the aperture of the mounting bracket and having a tubular body with a central bore therethrough, at least four of longitudinal extending circumferentially spaced slots through the tubular body communicating with the central bore to define at least first, second and third longitudinally coincident circumferentially spaced yieldable flexure fingers integral with the tubular body, at least the first and second of the flexure fingers being diametrically opposed from each other and having the third flexure finger disposed therebetween, integral abutment means carried by the first and second flexure fingers and adapted to coact with the mounting bracket in a manner to deflect said first and second flexure fingers radially inward upon insertion of the plastic guide through the mounting bracket aperture so that the abutment means is inserted through the aperture of the mounting bracket;
• a support post connected to the headrest and adapted to extend through the bore of the plastic guide and limit radially inward flexure of said first and second flexure fingers to effectively maintain the abutment means in engagement with the mounting bracket to prevent removal of the plastic guide from the mounting bracket;
• and
• spring means adapted to encircle the tubular body and said first, second and third flexure fingers and having curled ends seated respectively in a pair of said longitudinally extending slots disposed generally opposite of said third flexure finger, said spring means having a central inwardly bent portion bearing on said third flexure fingers to urge said third flexure finger radially inward into frictional engagement with the support post to frictionally impede movement of the support post within the seat back whereby the headrest is frictionally maintained at a desired position.
