Abstract
A damper assembly includes a fixed rack gear, a rotary gear damper having a gear engaged with the rack gear, and a tether movable with the damper along the rack gear and connected to the movable object to be controlled by the damper. A biasing element normally urges the damper away from anti-rotation locking members.
