ABSTRACT:
The present invention provides an apparatus and method of utilization thereof of a seat adjuster with a vertical height adjustment mechanism. The seat adjuster has a vertically fixed support. Pivotally mounted to the support is an interior threaded sleeve. Projecting through the sleeve is a rod connected with the seat with threads of an opposite hand of the sleeve. Interposed between the rod and the sleeve is a knob which is threadably engaged with both the sleeve and the rod. Rotation of the knob causes the knob to have relative motion with respect to the sleeve and the rod to have relative motion with the sleeve to set the elevation of the seat. The present inventive vehicle seat adjuster is particularly useful in tri-mount vehicle type seating.
