AIRCRAFT CABIN WINDOW SEALED ENCLOSURE

Abstract:

A window arrangement for a vehicle subject to pressure changes may include a first transparent member and a second transparent member spaced apart from one another. A flexible seal may be interposed between the first transparent member and the second transparent member. A hermetically sealed variable volume enclosure is sealed off from a cabin interior. The hermetically sealed variable volume enclosure may be bounded by the first transparent member, the second transparent member, and the flexible seal joining the first transparent member and the second transparent member around a perimeter thereof. The flexible seal may have an elastically mobile body structured and arranged to permit relative movement between the first transparent member and the second transparent member to change a volume of the enclosure in response to a pressure change in the cabin interior to equalize a pressure differential between the enclosure and the cabin interior.
