A vehicle seat suspension having a scissors arm linkage disposed between a platform and base with a link pivotally connected at one end to a scissor arm of the linkage at a point spaced from a pivot interconnecting scissor arms of the linkage and operably connected at its other end to a slide carried by the platform for communicating scissor linkage motion to a spring carrier also connected to the link. The carrier includes at least one coil spring held captive preferably in compression between two spaced apart brackets, one of which is pivotally connected to the end of the link adjacent the slide. The point of pivotal attachment of the link to the scissor arm is spaced from the linkage pivot to create a moment about the pivot tending to resist collapse of the linkage when force from the spring is communicated to the linkage. To adjust suspension weight resistance, the brackets are in communication with a rod attached to a knob that is rotated to change the distance between the brackets thereby changing the amount by which the spring is compressed. To change seat height, another knob is rotated to move the rod, springs, and brackets in substantially unison toward or away from the front of the suspension causing the linkage to controllably expand or collapse. By this suspension construction, weight adjustment is advantageously substantially independent of height adjustment.

[ What is claimed is:] [1.] A vehicle seat suspension comprising:(a) a base;(b) a platform 1) that is spaced from said base, 2) that overlies said base, and 3) that carries a seat;(c) a scissors linkage in operable communication with said base and said platform for enabling said platform to move relative to said base, said scissors linkage having one scissors arm pivotally connected to another scissors arm;(d) a spring 1) that is disposed between said platform and said base, 2) that opposes movement of one of said platform and said base toward the other of said platform and said base, 3) that is movable relative to one of said base and said platform, and 4) that carries a guide;(e) a slide carried by one of said platform and said base and having a channel;(f) a link operatively connected to one of said scissors arms and said spring; and(g) wherein said guide of said spring is received in said channel of said slide such that said guide is movable within said channel relative to said slide such that said slide substantially linearly guides movement of said spring.
