Rotational-translational double hinge-arm

The hinge includes a first flange and a second flange which pivot and translate with respect to each other. The first flange includes a first laterally offset pivot axis. The second flange includes a second laterally offset pivot axis and a translational path. Additionally, a pivot plate is provided with first and second parallel passageways. The first laterally offset pivot axis of the first flange engages the first parallel passageway of the pivot plate and the translational path of the second flange. The second laterally offset pivot axis of the second flange engages the second parallel passageway of the pivot plate. Initially relative pivoting of the first flange and the second flange causes the first laterally offset pivot axis of the first flange and the first parallel passageway of the pivot plate to translate within the translational path. Subsequent relative pivoting of the first flange and the second flange causes the pivoting about the first laterally offset pivot axis.
