2123136 9311985 PCTABS00022 The air cushion chambers of an air cushion vehicle are horizontally delimited by a skirt. The skirt comprises brushes with elongated downwards extended filaments (9), which have downwards diminishing cross-sectional area thereby providing the brushes with sufficient stiffness to maintain the pressure in the air cushion chamber and such a large flexibility in the lower section of the skirt that ice can hardly deposit thereon. The filament members are mounted in a guide profile (2) in such a manner that above the members there is a chamber (12) for dispersion and conveying of deicing fluid which form the chamber (12) via a flow passage in every filament member may pass down into a clearspace (10) between the filaments (9). It is possible to design at least one of the filaments (109) with a forwards protruding web (115) on one of its sides and a backwards protruding web (116) on its other side. When mounted, the webs of the filaments may seize each other when the skirt is transversely deflected and thereby the webs lock the individual brush members to one another which provides the skirt with a larger stiffness in the transverse direction.
