Abstract:
A seal for the surrounding structure of an opening formed in a motor vehicle bodywork, said seal comprising:(a) a first section piece (1) forming a clip of U-shaped cross-section, consisting of an elastomer or plastomer, said clip being seated over and grippingly engaging a projecting part of said surrounding structure of the opening; (b) a second section piece (5) of U-shaped cross-section constituted of an elastically deformable cellular material, which is coextruded with said first section piece and located at a side of the first section piece (1), such that the ends of the legs of the U-shape abut one of the legs of said first U-shaped section piece (1) so as to form a tubular member therewith, said second section piece (5) including at least one orifice (6) communicating the interior of said second section piece with the outside, said tubular member being compressible by an opening leaf operatively associated with the opening in the bodywork upon said opening leaf being moved into the closed position so as to form a seal with the surrounding structure; and (c) a third section piece (7) of an elastically deformable cellular material being located within the second section piece (5) and extending along at least a part of the length thereof, said third section piece (7) having a U-shaped cross-section which is smaller in size than the U-shaped second section piece (5) so as to form a space therebetween, the ends of the legs of said third section piece abutting the leg of the first section piece (1) which is abutted by the legs of the second section piece (5), and being coextruded with said first and second section pieces (1, 5), said third section piece (7) being designed to provide a localized resistance to any compressive force exerted by the opening leaf upon closing the opening of the bodywork while concurrently enhancing the sealing and soundproofing effects at the surrounding structure of the opening.
