ABSTRACT:
A joint assembly for allowing relative rotational movement of two structures. The joint assembly has a flexible member with a first surface facing a first direction and second surface facing a second opposite direction. The flexible member is typically a flexible circuit board or an electrical wire cable, that extends from a first structure to a second structure. The structures are interconnected so that they can rotate relative to each other. The flexible member is constructed in an essentially radial shape that defines an arcuate path. One end of the flexible member is attached to the first structure and the other opposite end is connected to the second structure. When the second structure rotates relative to the first structure, the end of the flexible member attached to the second structure moves along the arcuate path. As the flexible member moves along the arcuate path the member rolls over itself. That is, the portion of the flexible member that is rolled over, has its second surface facing the first direction instead of the second opposite direction.
