Abstract
Abstract A support member for a vehicle seat having a stationary member is disclosed. The support member has a support portion provided with a support torsion leg, opposed support cantilever legs projecting from the support torsion leg, and a second support cantilever leg connecting the support cantilever legs. One means of a first clamp means and a pivot means secures the support torsion leg to the stationary member. A spring portion of the support member has a spring torsion leg disposed adjacent one leg of the support torsion leg and the second support cantilever leg. Opposed spring cantilever legs project from the spring torsion leg and a spring connecting leg connects the spring cantilever legs. A second clamp means connects the spring torsion leg to the one leg.
