Abstract: A headrest mount has a rod having an upper end adapted to carry a headrest, extending along an axis, and formed with a plurality of axially spaced and radially outwardly open notches and a socket fitting having a tube in which the rod is axially centered and slidable and a head axially traversed by the rod and forming a slide compartment having upper and lower confronting planar surfaces extending generally perpendicular to the axis. A generally rectangular and wholly plastic slide plate in the slide compartment is formed with a central aperture through which the rod passes and has a pair of axially oppositely directed planar faces respectively engaging the surfaces of the compartment. The slide plate is a snug fit between the compartment surfaces.
