摘要: A back construction includes a back shell having stiff thoracic and pelvic regions connected by a flexible lumbar region in a manner adapted to ergonomically support a seated user. The back shell includes spaced-apart resilient edge strips and leaf springs attached to or embedded into the edge strip. The springs match a curvature of the strips and span the lumbar region, biasing the lumbar region of the back shell forwardly in a manner distributing stress applied to the lumbar region by the seated user.
