Abstract:
A counterbalance mechanism includes a first attachment strap that is fixedly attached to a body structure. An intermediate link is rotatably attached to the first attachment strap and rotatable about a winding axis relative to the first attachment strap. A first end of a second attachment strap is rotatably attached to a moveable panel. A second end of the second attachment strap is rotatably attached to the intermediate link, with the second attachment strap and the intermediate link rotatable relative to each other about a link axis. A spiral spring interconnects the first attachment strap and the intermediate link. The spiral spring biases the intermediate link about the winding axis to rotate the intermediate link and the second attachment strap relative to each other about the link axis, in a scissor-like motion, to rotate the panel relative to the body structure.
