Abstract
A seat cushion pad supporting construction has a base frame having an opening, and a planar spring deck disposed substantially over the opening. The planar spring deck is formed of a rectangular boundary frame and flexible support members extending front-to-rear between front and rear boundary frame portions of the boundary frame. The flexible support members may be spring steel wires or flexible planar members made of synthetic resin, rubber or fabric. The spring deck is non-resiliently connected at its front boundary frame portion to a front portion of the base frame adjacent the opening to be vertically pivotable with respect to the front base frame portion. The rear boundary frame portion is resiliently connected by tension springs to a rear portion of the base frame adjacent the opening. Optional front and side protruding spring frames are connected to the boundary frame to support the upper legs of an occupant. An optional pivotable linking mechanism supports the front boundary frame portion so that the portion is vertically pivotable with respect to the front base frame portion.
