Abstract: A damper (10) includes a frame (12), a main gear (14) mounted on the frame (12) for rotation about an axis of rotation (A 16 ), and a spring (24) operably connecting the main gear (14) and the frame (12) such that rotation of the main gear (14) tensions the spring (24). The main gear (14) has a circumferential recess (18) formed therein that defines a circumferential channel or reel. An elongate flexible member (22) is wrapped around circumferential recess (18) in the main gear. A gear damper (38) is mounted on the frame (12) and is operably engaged with the main gear (14) to dampen rotational movement of the main gear (14). The damper (38) can be configured for one-way or two-way damping.

Abstract: A damper (10) includes a housing (28), a cover (20), a rotor (90) and a valve (70) relatively rotatable with respect to the rotor (90). When the rotor (90) is rotated in one direction, a space between the valve (70) and the rotor (90) is opened to increase damper fluid flow and reduce damper resistance. When rotated in an opposite direction, the space between the valve (70) and the rotor (90) is closed to decrease damper fluid flow and increase damper resistance. A shaped flange (84) on the rotor may provide a changing space between the rotor and ribs in the housing when the rotor is rotated. The cover (20) is self-centering on the housing (28) and is capable of being secured by ultrasonic welding.

Abstract: A damper (10) includes a housing (20) and a rotor (30). A portion (34) of the rotor (30) extends outwardly of the housing (20) and has a gear rotatably (66) disposed thereon. A coil spring (64) encircles the portion (34) of the rotor, and has an end segment (68) secured to the gear (60). Rotation of the gear (60) in one direction tightens the grip of the spring (64) on the rotor (30), and rotation of the gear (60) in the opposite direction loosens the grip of the spring (64) on the rotor (30). This provides a simple one-way operation of the damper.
