Abstract
Abstract A plastic guide is provided for mounting a headrest to a vehicle seat back. The guide is an elongated plastic member having a through bore, locking tangs on one end, intermediate shoulders, which terminate in spaced fingers, a trim flange on the other end, and a spring finger entering the bore. The guide is inserted through a hole in the upholstery of a trimmed seat back and through aligned apertures in a seat frame tube so that the locking tangs cooperate with the shoulders to lock the guide to the tube and the fingers snap over the tube to prevent relative rotation. The spring finger engages detent notches in the headrest support post to position the headrest relative to the seat back. An axial slot in the guide permits insertion of an elongated tool to pry the spring finger out of a locking notch to enable removal of the post to separate the headrest from the seat back.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A guide for mounting a headrest post on an automotive seat structural tube having aligned apertures on opposite surfaces, wherein the post has a plurality of spaced detent notches, the guide comprising: an elongated plastic guide body having a seat upholstery-engaging flange on one end, an intermediate shank including a shoulder engaging the tube adjacent one aperture, a locking tang on the other end for engaging one side of the tube adjacent the other aperture to cooperate with the shoulder and lock the guide to the tube upon insertion of the guide through the apertures, a finger extending from one side of the shank to embrace the tube intermediate the apertures to prevent rotation of the guide relative to the tube, a central through bore for receiving the post, a groove in the shank intersecting the bore, and a spring normally occupying the groove for engagement with the post detent notches to position the post within the guide and being movable out of the bore to enable repositioning of the post, whereby the guide may be inserted through the apertures after the automotive seat is trimmed.
Claim 2
Dependent Claim
