Abstract:
A system comprising:a support, a flexible cover that covers the support and comprises at least two adjacent parts joined to each other by a seam along a join line, forming a seam flap comprising two margins that belong to the two respective cover parts and that are folded over towards the support from said join line, the seam flap extending from said join line to a free edge and said seam flap having a first face and a second face that belong to the two respective margins, said seam passing around the seam flap and enclosing the free edge of said seam flap from the join line, and, fastened to the support, at least one self-gripping element that comprises hook devices that hook into said seam, wherein the seam comprises at least a first thread and a second thread joined to the first and second faces, respectively, of the seam flap along said join line, the first and second threads forming loops that alternate between the first and second faces of the seam flap, each said loop of the first thread passing through two adjacent said loops of the second thread and each said loop of the second thread passing through two adjacent said loops of the first thread around, the free edge of the seam flap, wherein said loops of the first and second threads form a mesh in which the seam flap is held tightly and without slack, wherein the loops of the first thread are sewn and tensioned so that said loops of the first thread force the seam flap to fold over towards said first face, and wherein the second face of the seam flap faces toward the support and the loops of the second thread hook onto the hook devices of the self-gripping element on said second face of the seam flap.
