Abstract
A rotational hinge for use with a flip cover moveable between a first position and a second position in response to a biasing force is disclosed. The rotational hinge includes a housing integrated with a flip cover and capable of rotational movement about a central axis between the first and second positions. A torsional spring mechanism integrated with the housing converts a biasing force along the central axis of the housing into rotational movement about the central axis of the housing when moved from the first to the second positions. A damping mechanism connected to the torsional spring mechanism damps the biasing force along the central axis of the housing.
