Abstract
This invention provides a hinge assembly having variable friction resistance. The hinge assembly includes an elongated element having a generally cylindrical surface extending longitudinally. It also includes at least one torque element having a generally cylindrical surface compressively engaged with the cylindrical surface of the elongated element, the cylindrical surface of the at least one torque element having end portions. An actuator of the hinge assembly is configured for changing friction resistance generated by the at least one torque element by changing the relative position of the end portions of the at least one torque element, thus reducing compressive engagement between the cylindrical surface of the at least one torque element and the cylindrical surface of the elongated element.
