Abstract
A friction hinge with its motion restricted in one pivoting direction includes a support member, a restricting module, and a pivot member. The restricting module is mounted on the support member. The restricting module has an air flow opening. The pivot member is pivotable relative to the support member and the restricting module. A regulating chamber is defined between the pivot member and the restricting module. When the pivot member is pivoted in one direction, a pressure in the regulating chamber is increased and the restricting module is actuated to reduce size of the air flow opening, increasing the resistance to pivoting of the pivot member in this pivoting direction.
