Abstract

Airflow control devices are provided that may be employed in passenger transport vehicles (e.g., passenger transport aircraft, trains, buses, automobiles and the like) that allow individual passengers to selectively control direction and volume of incoming airflow to thereby enhance passenger comfort. According to certain embodiments, passenger airflow control devices are provided with an open-ended domed shell, a receiver immovably fixed to an upper end of the shell and a central air distributor assembly operatively connected to the receiver for receiving an incoming airflow and discharging the airflow to a passenger. The central air distributor assembly may include a central distributor bowl which defines a laterally oriented airflow discharge opening, a central disk which is positionally fixed to and closes a lower end of the central distributor bowl, and an air distributor hub having a lower end immovably connected to an upper end of the central distributor bowl and an upper stem having an air inlet cutout which is received within and rotatably connected to the receiver.
