Zusammenfassung:	A variable friction hinge has a pintle, a stationary leaf and a washer assembly. The pintle is attached securely to a cover of an electronic device. The stationary leaf is attached securely to a base of the electronic device. The washer assembly is mounted around the pintle and has a stationary abrasion washer and a rotating abrasion stationary washer. The rotating abrasion washer has an eccentric hole engaging the pintle. With the eccentric hole engaging the pintle, the rotating abrasion washer alternatively rubs fully or partially against the stationary abrasion washer. Therefore, the hinge provides variable friction.
