There is disclosed a friction hinge assembly capable of providing hinged motion of two elements with a programmable frictional torque. The frictional torque can be made to vary with the angular orientation of the two hinged elements. The frictional hinge assembly is comprised of a band wrapped around a pintle which is constrained to move rotationally with the first hinged element. One end of the band has a lug configured to press against the second hinged element, exerting thereupon a torque about the pintle. The other end of the band has a tail to which is applied a controlled force to produce the desired frictional torque between the band and the pintle. |
