Abstract
A friction hinge comprising a shaft and a band including a spring portion which is rotatable relative to the shaft and wrapped tightly about the shaft for providing frictional torque between the shaft and spring portion is provided. The shaft includes a contact member for engaging the spring portion when the spring portion is rotated in one of two rotational directions and reaches a selected rotational position with respect to the shaft. Further rotation of the shaft in that direction causes the spring portion to loosen about the shaft.
