A lumbar support mechanism comprising:
- a frame member being flexiable through a range of flexion, said frame member having a variable resilience, said variable resilience varying through said range of flexion such that increased flexion stiffens said variable resilience of said frame member, said frame member being adapted to be supported at an upper portion and a lower portion;
- an adjustment device operatively engaged with said upper portion and said lower portion of said frame member such that adjustment of said adjustment device varies said flexion;
- and
- two partial panels, said partial panels being disposed in opposite directions;
- said partial panels being integral with and circumscribed by said frame member, said partial panels being further defined by two U-shaped slots in said frame member, said partial panels having a panel resilience,
- wherein said panel resilience remains substantially unchanged through said range of flexion of said frame member.
