Claim:
An occupant lumbar support system for a furniture member, comprising: a flexible occupant lumbar support member having first and second connection braces, the lumbar support member deflectable to any one of a plurality of occupant lumbar support positions; at least one guide rod slidably disposed through both the first and second connection braces operating to slidingly guide the first and second connection braces during movement of one of the first and second connection braces toward or away from the other of the first and second connection braces; a support tube oriented transverse to the at least one guide rod and rotatable to maintain continuous contact between the support tube and the at least one guide rod such that the support tube provides continuous contact support for a first end of the lumbar support member; a lumbar member actuation mechanism connected to a body of the support tube; a bracket fixedly connected to the support tube; and first and second biasing elements each connected to the bracket and to the lumbar member actuation mechanism, the second biasing element having a spring constant and a biasing force greater than a spring constant and a biasing force of the first biasing element, the second biasing element in a fully retracted position of the lumbar support member being flexibly extended, with the second biasing element biasing force acting through an over-center force path permitting the biasing force of the first biasing element to retain the fully retracted position of lumbar support member.
