Abstract:
A damper includes a frame, a main gear mounted to the frame for rotation about an axis of rotation, and a spring operably connecting the main gear and the frame such that rotation of the main gear tensions the spring. The main gear has a circumferential recess formed therein that defines a circumferential channel or reel. An elongated flexible member is wrapped around the main gear, disposed within the circumferential channel. A gear damper is mounted to the frame and is operably engaged with the main gear to dampen rotational movement of the main gear. The damper can be configured for one-way and two-way damping.
