Abstract: A partially movable divider assembly primarily designed for mounting to an overhead structure, such as a passenger service unit rail or ceiling, in the cabin interior of an aircraft, to provide a privacy barrier between two seating sections of different classes. An upper stationary panel is fixedly mounted to the overhead structure and a lower movablle panel is hingedly attached along a bottom edge of the upper panel to permit swinging movement of the lower panel relative to the upper panel in response to a force applied to the lower panel. A biasing element and dampening structure urge the lower panel into a normal vertical position in coplanar relation to the upper panel, while reducing excessive swinging movement thereof.
