Patent ID: 7059959

Claim:
A closure for an opening of an air-conditioning system, comprising a motor vehicle heating/air-conditioning duct forming an air passageway having an opening; a plurality of essentially planar closing elements that are displaceably positioned essentially in a single plane, in a manner such as to be displaceable along a displacement direction essentially within said plane and parallel to one another, so as to selectively open and close at least one portion of said opening, wherein adjacent closing elements include a structural element that causes them to inter-engage one another in a manner such that displacement of a first adjacent closing element by a predetermined distance causes the second adjacent closing element to move together with the first adjacent closing element, and wherein each respective closing element includes at least one sealing lip on one of its planar surfaces, along each outer edge that is perpendicular to the displacement direction, for sealing adjacent closing elements against the passage of air in at least a position in which the adjacent closing elements close a portion of said opening; and a displacement mechanism for displacing the closing elements with respect to one another, either in the same direction or in opposite directions along the displacement direction.
