An adjustable seat suspension system for a vehicle seat for a tractor, earth working equipment, or the like, and in which the seat is resiliently supported by a pressurizable air bag. The seat suspension system provides a manually settable lever by means of which the operator can infinitely vary the height adjustment of the seat for a normal operating position, depending on his size. The seat suspension adjusting mechanism includes a valve for regulating the flow of pressurized air to or from the air bag. The arrangement is such that for any vertical height position selected by the operator, the air controlling mechanism permits the seat to oscillate up and down through a given range of movement, say for example six and one-half inches. In addition to a normal operating oscillation range for any selected height adjustment, the seat suspension control system of the present invention includes a floating pivot point in the control linkage which can shift from its normal operating position to thereby in effect disconnect the control valve and protect it when the seat movement exceeds the limits of the valve spool, which limits are small compared to overall linkage movement requirements.

In a vehicle seat suspension mechanism for vertically, adjustably, and resiliently supporting a vehicle seat, the combination comprising; a base frame, a seat frame, means mounting said seat frame on said base frame for vertical shifting of the seat frame relative to the base frame, an air spring mounted between said seat frame and said base frame, an air valve mounted on said base frame and having a conduit connection with said air spring for conducting flow of air to and from said air spring, said air valve having means for connection to a source of air presssure; said valve also having a shiftable valve element which is shiftable between a neutral position, air spring pressurizing position, and an air spring exhaust position; a control handle mounted on said seat frame, and linkage means between said handle and said shiftable valve element; said linkage means including a floating link, a lost motion connection between said handle and one end of said floating link, said link being connected to said shiftable valve element intermediate the length of said floating link, said floating link having a pivot point at its other end, and means for mounting said pivot point of said floating link and permitting said pivot point to shift from a normal position when said seat frame assumes an extreme position in either an upper or downward direction to thereby render said valve inoperative when said seat frame is in said extreme positions.
