Adjustable hinge and support structure

摘要

An adjustable hinge has a cam structure and a pin engaging one of multiple openings to interact with the cam structure and establish a range of rotation for the arms of the hinge. The range of rotation for the hinge is adaptable depending on which of multiple openings is selected for insertion of the pin. A bracket provides for modification in the location of the hinge with respect to a support member as well as the location of an armrest with respect to the bracket.
