Abstract
A seat suspension system having a seat cradle, a seat mounted in the seat cradle and an anchor body having a plain rectangular box-like shape disposed behind the backrest portion of the seat. A pair of spaced-apart plain parallel anchor plates encloses the anchor body. There are also provided two pairs of spaced-apart parallel bars each having spaced-apart first and second ends, the first ends being movably connected to the anchor body and the second ends being movable connected to the seat cradle for allowing a movement of the seat cradle relative to the anchor body. An air bellows is mounted inside the anchor body. The air bellows has an upper end connected to the seat cradle and a lower end connected to the anchor body. A variety of attachment kits may be affixed to the anchor plates for mounting the seat suspension system to different models of industrial vehicles.
