ABSTRACT:
A body support moveable between unfolded and folded positions comprises: serially interconnected body, cavity and seat sections defined by respective upper and lower grids and including resilient members. The body, cavity and seat sections have their upper and lower grids positioned to be substantially coplanar in the unfolded position, and the seat section overlies the body section in the folded position. The resilient members of the seat section are generally planar and are arranged in a plurality of transverse rows. The resilient members are pivotally attached to the seat section upper and lower grids such that, in the unfolded position, the resilient members of the seat section are erect and extend substantially normal to the seat section upper and lower grids, and in the folded position, the resilient members of the seat section pivot relative to the seat section upper and lower grids to bring the seat section upper and lower grids adjacent each other. The seat section lower grid further comprises a lower border wire which comprises a pair of longitudinal runs and a transverse run therebetween. The transverse run of the upper border wire is positioned above and interconnected with a row of the seat section resilient members spaced farthest from the cavity section; also, the transverse run of the lower border wire is spaced rearwardly from the seat section resilient members. The seat section upper grid comprises a pair of upper border wires, each of which extends longitudinally above a respective lower border wire longitudinal run. A transitional border wire has a pair of longitudinal runs and a transverse run positioned therebetween. The transitional border wire is pivotally interconnected with the seat section lower grid. The transitional border wire transverse run is spaced rearwardly from the resilient members and above the lower border wire transverse run.
