Abstract
A torque hinge 20 includes a shaft 14 surrounded with a coating 22 fixed to the shaft 14. The coated shaft 18 fits within a housing cavity 26 such that the coated shaft 18 is in frictional contact with the housing cavity 26. The frictional contact provides sufficient torque to torque hinge 20 to provide constant resistance through the torque hinge's entire range of motion.
