ABSTRACT:
A damper includes a housing and a rotor. A portion of the rotor extends outwardly of the housing and has a gear rotatably disposed thereon. A coil spring encircles the portion of the rotor, and has an end segment secured to the gear. Rotation of the gear in one direction tightens the grip of the spring on the rotor, and rotation of the gear in the opposite direction loosens the grip of the spring on the rotor.
