Technical Examples

A back construction includes a back shell mounted on a back frame at top and bottom connections, and a flexible lumbar section biased forwardly by a biasing device. The bottom connection is located rearward of the back shell to allow unencumbered sliding entry into the seating unit from a lateral side position, but the bottom connection defines a virtual pivot forward of its physical location to provide the desired path of flexure when the lumbar section is flexed. In one form, the bottom connection is a pair of non-parallel links of dissimilar length. In another form, the bottom connection is a follower with two bearings following a guide slot. In some variations, the force of the biasing device is variable. Seating units incorporating the back construction include a vehicle seat, a foldable portable stadium seat, and a wheelchair seat.
