<p>Hydromassage carpet, constituted by a substantially rectangular envelope (1) formed by two sheets (11-12) welded together the welding thereof comprising a peripheral toe (21) extended along the entire edge of the envelope and a second inner toe (22) so shaped as to define a first sealed duct (31) and a second duct (32) closed at its one end (321) and connected at its other end (322) to a pipe (4) for feeding compressed air. The two ducts (31-32) are obtained with a plurality of inner longitudinal toes (221) parallel to each other as well as to the side toes (211), thereof, adequately spaced therefrom and to each other as well as extended up to near the lower (212) and upper peripheral toes (213), adequately spaced therefrom, such longitudinal toes (221) being also alternately interconnected at their ends to additional lower (222) and upper toes (223) orthogonally thereto, so as to form a serpentine path. Holes (5) are provided at the upper part of said second duct (32), adapted to permit the compressed air to leave, thereby generating the hydromassage effect.</p> |
