A device includes an air curtain generator including air curtain diffusor able to diffuse at least one air curtain along a plane, in at least first and second different diffusion directions. The air curtain generating device includes a control unit able to control the diffusion of the at least one air curtain in one and/or the other of the first and second diffusion directions.

A system includes an outflow vent that has a cap releasably mounted to a panel within an internal cabin of a vehicle. The cap is elongated from a first end of the cap to a second end of the cap opposite the first end. The cap has a base wall that is overlaid on the panel and defines at least one slot therethrough. The cap receives an airflow generated by an airflow generator, and the at least one slot emits the airflow from the cap to form an air curtain within the internal cabin.

An apparatus provides an air shield over a portal access opening between a vehicle access member and a stationary vehicle trim member. An air supply device disposed within the vehicle. The air supply device includes an active material creating the burst of air. The air supply device produces a burst of air that discharges upon opening of the vehicle access member. At least one output port outputs the burst of air. The burst of air 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.

An apparatus configured to expel a medium outwardly from an opening of a motor vehicle to inhibit the medium from entering an interior cabin of the motor vehicle upon opening a closure panel closing off the opening, motor vehicle therewith, and method of expelling a medium outwardly from an opening of a motor vehicle. The apparatus includes an air duct and a source of high-pressure air configured to generate high pressure air flow through the air duct to expel the medium outwardly away from the interior cabin.

A vehicle enclosure (14) and method and system of installation using an adhesive-backed attachment device (1) having a base (4) with an adhesive backing (10) and a stud (12) or a socket (2) that engages a conventional a conventional snap (8). The adhesive-backed attachment device is preferably flexible so that it may be attached to uneven surfaces of a vehicle, such as a golf cart (15). The adhesive-backed attachment device eliminates unsightly brackets, drilling or screwing into the golf cart and cuts down on installation time of golf cart enclosures. The studs and sockets may also be integrated into a new roof (14) for retrofitting an existing golf cart.
