Structural head restraint guide

Abstract

A head restraint guide assembly mounted into apertures formed in a seatback frame for receiving support posts of a head restraint. The head restraint guide allows for incremental adjustment and locking of the height of the head restraint relative to the seatback frame. The guide assembly has opposite upper and lower ends. A center bore extends between and through both of the upper and lower ends. The guide assembly comprises a generally cylindrical main body having upper and lower portions. A lip is formed in the upper portion adjacent to the lower portion. A lattice of structural ribs extends outwardly from the upper portion and extends between the lip and the upper end of the guide assembly. The lower portion comprises a pair of symmetrically opposite and spaced apart legs that extend downwardly from the upper portion. The legs are elastically inwardly displaceable. Each leg includes a ramped surface to facilitate insertion into the seatback frame. Each ramped surface terminates at a locating edge. The lip and the locating edge together serve to axially locate and lock the guide assembly in the apertures of the seat back.
