Abstract
A clutch assembly for a four way manual seat adjuster is provided which includes a stationary cylindrical housing in which is disposed a pair of coil clutch springs. The springs are biased to expand radially outwardly into frictional engagement with the housing whereby rotation of the springs is prevented. A torsion tube extending concentrically through said housing is coupled to the springs so that rotation of the torsion tube is prevented when the springs are frictionally engaging the housing. A release handle is provided to selectively release one spring or the other enabling rotation of the torsion tube in one direction. The four way manual seat adjuster linkage is coupled to the torsion tube to raise and lower the seat upon rotation of the torsion tube.
