Abstract
A lumbar support adjusting apparatus has a release plate pressed against a ratchet by a compression spring for urging the release plate under uniform resilient forces, and biased to return in its direction of rotation by a torsion spring, preferably a spiral spring, having one end secured to a shaft and the other end to a support plate. The compression force of the compression spring, and the torsional force of the spiral spring can be set independently of each other. The release plate can turn the ratchet and can be angularly returned to its original position smoothly and reliably without fail.
