Hinge assembly for car-mounted video display unit

A hinge assembly for mounting a screen of a video display to the interior of an automobile, comprising:

• a body, adapted to couple the screen to the interior of the automobile;
• an open shaft, with the generally middle portion of the open shaft coupled to the body and two ends of the open shaft adapted to be coupled to the interior of the automobile, said open shaft adapted to pivot the screen about a first axis, the open shaft having a recess at the generally middle portion;
• a rotate shaft, with one end adapted to be coupled to the screen and a body portion of the rotate shaft coupled to the body, said rotate shaft adapted to pivot the screen about a second axis, transversal to the first axis, the rotate shaft having at least one recess, the rotate shaft being in contact with the open shaft at their recesses;
• wherein the recess on the open shaft allows the rotate shaft to rotate, the recesses on the rotate shaft allow the open shaft to rotate, the non-recess portion of the open shaft prevents the rotate shaft to rotate and the non-recess portion of the rotate shaft prevents the open shaft to rotate.
