Abstract: A frictional hinge assembly for use with electronics devices such as computer notebooks having base and lid portions may present a higher level of frictional resistance to rotation in one direction than in the other. The hinge may comprise a base-mounted helical sleeve having loops that embrace a rotational shaft that is connected to a lid.

The helical hinge may have applicability for notebook computers, electronic devices having clamshell form factors, all-in-one designs and tablets using kickstands and the like.
