Abstract:
A friction hinge assembly comprising:a first member and a second member rotatably connected thereto for enabling said first member to be disposed at varying angular positions relative to said second member; a shaft fixedly coupled to said first member; a band fastened to said second member, said band including a spring portion frictionally wrapped about said shaft for providing frictional torque between said shaft and said spring portion; a cam mechanism comprising a first cam member fastened to said first member and rotatable with said shaft, and a second cam member fastened to said second member, said first cam member being engageable with said second cam member at a selected angular position; wherein said shaft and said frictionally wrapped spring portion of said band are rotationally aligned such that the frictional torque exerted between said shaft and said spring portion is reduced substantially when said first cam member engages said second cam member.
