Abstract
An air shield is provided over a portal access opening between a vehicle access member and a stationary vehicle trim member. The vehicle access member provides access to a compartment of an interior of the vehicle. An air supply device is disposed within the vehicle. The air supply device is capable of producing a burst of air that discharges upon opening of the vehicle access member. An air concentrator device is in fluid communication with the air supply device. The air concentrator device outputs the burst of air that forms the air shield in a direction substantially transverse to the portal opening. The air shield is formed across at least a portion of a perimeter of the portal access opening between the vehicle access member and the stationary vehicle trim member. The air shield inhibits precipitation from entering the compartment of the vehicle during a pressure equalization phase that occurs in response to the opening of the vehicle access member.
