Abstract
An adjustable air vent assembly has a frame and a plurality of louvers pivotally mounted to the frame. The plurality of louvers is movable between a closed position and a diffuse position. In the closed position, each louver has an edge contacting an edge of at least one other louver to substantially prevent air from flowing through the plurality of louvers in the closed position. In the diffuse position a first louver is oriented along a non-parallel plane with respect to a second louver. A single actuator is provided for moving the plurality of louvers between the closed and diffuse positions.
