<p>There is disclosed a friction hinge assembly capable of providing hinged motion of two elements (1, 3) 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 (17) wrapped around a pintle (5) which is constrained to move rotationally with the first hinged element. One end of the band has a lug (19) configured to press against the second hinged element, exerting thereupon a torque about the pintle. The other end of the band has a tail (25) to which is applied a controlled force to produce the desired frictional torque between the band and the pintle.</p> |
