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.
