Abstract

A tubular bushing (26) assembly made of plastic material and disposed in an opening (24) defined by a pair of spaced sheets in a seat back (14) of an automotive vehicle to adjustably support each of the posts (22) of a headrest (20). The bushing (26) comprises an outer sleeve (28) presenting ribs (32, 34) for engaging the edges of the opening (24) in each of the sheets of the bracket of the seat back frame (18) and an inner sleeve (30) for insertion within said outer sleeve (28) for slidably supporting the post (22) and having hoop rings (46, 48) for forcing the outer sleeve (28) radially outwardly to deform the ribs (32, 34) about and into gripping engagement with the edges of the openings (24).
