ABSTRACT:
An automotive vehicle headrest system comprises a pair of laterally spaced upstanding support shafts or bolt members for threaded engagement within internally threaded or tapped holes, sockets, or sleeves defined within an automotive vehicle seat frame. The headrest component includes bracket members, having disk members incorporated therein, which are mounted upon the shafts or bolts such that the bracket/disk assemblies are normally mis-aligned with respect to each other, and the disk members define two-point contact systems with the shaft or bolts so as to support the headrest at a predetermined elevational position. Vertical positional adjustment of the headrest is achieved by causing the bracket members to be aligned with each other thereby releasing the two-point contact system defined with the shafts or bolts whereupon movement of the headrest to a new elevational position, the two-point contact system is re-established so as to again permit support of the headrest upon the support shafts or bolt members.
