Abstract
A vehicle seat assembly includes an actuator controlled by a three-position spool valve which is connected by an adjustable two-link linkage to the seat. The valve is directly responsive to the geometry of the linkage to urge the seat, regardless of the load on the seat, to a ride position established by the linkage.
