Abstract:
A friction hinge assembly comprising:a first element and a second element rotatably connected thereto for enabling the first element to be rotatably disposed at varying angular positions relative to said first element; a shaft; a first band fixed to said first element and having a spring portion rotatably and frictionally wrapped in a first direction about said shaft for providing a frictional torque therebetween such that said spring portion of such first band tends to loosen in one direction of rotation and tighten in the other direction of rotation; a second band fixed to said second element and having a spring portion rotatably and frictionally wrapped in said first direction about said shaft for providing a frictional torque therebetween such that said spring portion of said second band tends to loosen in said other direction of rotation and tighten in said one direction of rotation; wherein said spring portion of said first band has a first limited angular range of rotation relative to said shaft in said one direction of rotation and said spring portion of said second band has a second limited angular range of rotation relative to said shaft in said other direction of rotation.
