Inflatable and extendable vehicle skirt

摘要

An inflatable and extendable skirt for reducing the air drag caused by a moving motor vehicle such as a truck. The skirt is normally rolled up on itself and can be extended, as between parts of the vehicle, upon introduction of the compressed air into the pocket chambers secured to the skirt. The skirt can be inflated or deflated automatically when the motor vehicle passes a predetermined speed or whenever an operator feels it is beneficial to inflate or deflate one or a plurality of skirts.
