Abstract
A height adjustable seat suspension having first and second bases connected by a linkage assembly with an air spring and shock disposed between the bases. The shock dampens vertical movement of the bases and the air spring increases in air volume to raise the seat height of the suspension and decreases in air volume to lower the seat height of the suspension. A threaded rod is also included as part of the shock which is threadably engaged with a collar that is rotated by a drive source. The engagement between the threaded portions of the rod and collar axially repositions the rod with respect to said collar to change the effective length of, the shock.
