An adjustable bearing system, one ideally suited for use in vehicle seat
suspension for aft positioning assemblies and isolator assemblies, and
having an adjustment mechanism that is readily accessible and easy to
use. The adjustable bearing system includes a first structure, a second
structure, and a bearing adjustably disposed between said first and
second structures for facilitating movement of one structure relative to
the other. A bearing driver is positioned to engage a non bearing surface
of the bearing and to adjust the position of the bearing relative to said
first and second structures, and an actuator cooperates with the bearing
driver to permit adjustment of the bearing's position.
