A vehicle closure member sealing system includes a first seal including a first bulb section and an inflatable geometric feature disposed on a discrete portion of the first seal. The inflatable geometric feature includes a second bulb section separate from the first bulb section. A pressure source is configured to communicate a fluid into the second bulb section to inflate the inflatable geometric feature between a first position and a second position. The vehicle closure member sealing system may be utilized to seal a side door or liftgate.

A sealing structure of an active weather strip is arranged such that a nozzle resin is mounted in an air injection hole connected to an air chamber formed inside the weather strip in the shape of a closed type ring, and an air control module is connected to the nozzle resin through an air hose. In response to driving conditions of a vehicle, air is injected into or discharged from the air chamber inside the weather strip by an air control module to adjust a reaction force of the weather strip, so as to improve door closing characteristics and minimize an inflow of wind sounds while maintaining airtightness even at a high pressure.

A door construction for an airborne vehicle includes a door, a door frame, with the shape of door frame forming a gap between the door and the door frame in the outer surface of the door and the door frame when the door is closed, and a gap sealing device comprising an inflatable tube positioned in the gap with at least one tube inlet, the inflatable tube being configured to be inflated through the at least one tube inlet and to at least partially seal the gap between the door and the door frame when inflated.

A roll-up door assembly including a plurality of door panels; a pneumatic seal apparatus having an elastic membrane of an elongated tube disposed around a perimeter of the trailer door so as to be adjacent to the plurality of door panels, wherein pressurized air is injected into the pneumatic seal apparatus to expand the elastic membrane and to apply an outward force against multiple sides of the plurality of door panels, wherein applying the outward force against the plurality of door panels on multiple sides keeps the plurality of door panels as a single unit such that substantially less air flows through the plurality of door panels than prior to the application of the outward force to seal the trailer door.
