Abstract: A vehicle door seal venting system is provided for venting air trapped in the seal gap between two or more spaced environmental seals. As the vehicle door transitions to a closed position, the seals engage between the vehicle door and vehicle body door opening, acting to closeout the seal gap. The compression of the seal gap as the door further closes results in pressurization of the trapped air, which then acts to resist closure of the vehicle door, therefore requiring that additional closure force be applied to fully close the door. The vehicle door seal venting system relieves the pressurized air from between the seals without compromising the integrity of the seals or overall noise and sealing performance of the door system.

Abstract: An air extractor assembly for an automotive vehicle is disclosed which has first and second air extractor valves mounted in a body panel. The first air extractor valve opens when pressure within the passenger compartment at a first pressure differential and the second air extractor valve opens at a second higher pressure differential. The second flap has a weight, which by virtue of gravity, resists opening. The weight can be a magnetic strip that is attracted to a ferrometallic and/or magnetic strip applied around the second aperture. By providing air extractor valves which open at different pressure differences, only the first air extractor valve opens when the pressure difference is in a lower range thereby limiting noise transmission into the passenger compartment. When a car door is shut and/or the climate control system is operating at maximum, the pressure difference is greater causing both extractor valves to open.
