Abstract
A vehicle seat suspension includes a bottom frame adapted to be mounted on the vehicle and a top frame located above the bottom frame and adapted to support a seat thereon. A substantially fully collapsible scissors linkage is interconnected between the bottom frame and the top frame enabling the bottom frame and the top frame to move relative to each other substantially in parallelism. A biasing arrangement is disposed between the top frame and the bottom frame and has a preload force urging the top frame away from the bottom frame. A first adjustment mechanism is located in the top frame and selectively enables fore and aft adjustment of the top frame relative to the bottom frame. A second adjustment mechanism is located between the bottom frame and the top frame and selectively enables an adjustment on the biasing arrangement in accordance with the weight of an occupant in the seat by translating a horizontal force applied along the bottom frame into a vertical force affecting the preload force of the biasing arrangement.
