Abstract
A low profile seat suspension includes a bottom frame adapted to be mounted on a vehicle, and a top frame located above the bottom frame for supporting a seat cushion and seat back 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 parallel. 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 to an adjustment plate into a vertical force effecting the preload force of the biasing arrangement. The invention is improved wherein an adjustment knob is positioned at a front of the seat and the knob is enabled to move along with the top frame irregardless of the fore and aft adjustment of the top frame relative to the bottom frame.
