Abstract
A friction hinge system for a laptop computer is provided. The system allows the computer display to move easily from a closed condition toward various operating angular positions while providing a greater torque for maintaining selected angular orientation. The system includes two or more bands wrapped in the same direction about a common shaft as well as a stop features for limiting the angle of rotation of each band relative to the shaft.
