ABSTRACT:
A sprung seat frame for a seat comprises a seat plate for carrying for example upholstery and a base plate for mounting the seat for example on a motor vehicle floor. A scissor-type lever assembly comprising first and second levers which cross and are pivotally connected together is operatively disposed between the seat plate and the base plate. A seat frame springing system includes a compression spring disposed between the lever assembly and the base plate. To produce a softer spring characteristic than would otherwise correspond to the spring characteristic of the compression spring, the seat frame includes a correction spring which is operatively arranged between the two levers at least approximately parallel to the seat and base plates so that upon sprung downward movement of the seat plate the correction spring moves from a position above the pivotal interconnection of the levers to a position beneath the interconnection.
