Patent abstract
A vent assembly has a base and a cover connected to the base. The cover moves between a closed and open position. A fan is optionally mounted for rotation in the base. A mechanism, including a strut system, raises and lowers the cover. The strut system is connected with the cover at two positions spaced from one another. When the cover is in its closed position, a retention force is provided by the strut system and is distributed about the cover.
