<p>An automotive vehicle headrest system (10) comprises a pair of laterally spaced upstanding support shafts (26) or bolt members for threaded engagement within internally threaded holes, sockets, or sleeves defined within an automotive vehicle seat frame. A headrest component (38) includes bracket members (12), having disk members (34) incorporated therein, which are mounted upon the shafts (26) such that the bracket/disk assemblies (12,34) are normally mis-aligned with respect to one another, and the disk members (34) define two-point contact systems with the shafts (26) so as to support the headrest (38) at a predetermined elevational position. Vertical positional adjustment of the headrest is achieved by causing the bracket members (12) to be aligned with one another thereby releasing the two-point contact system defined with the shafts (26) to allow movement of the headrest (38) to a new elevational position. The two-point contact system is then re-established to support of the headrest upon the support shafts (26) at the new location. <IMAGE></p> |
