This invention is an attachment fitting for use on the flexible wall of a structure. In detail, the fitting (24) includes a slot (36) in the wall (30) of the structure. A first flexible member (40) is included having a center portion (42) folded over its self forming a loop extending through the slot (36) from a first side (32) of the wall (30) and out from the second side (34), and outer fan shaped portions (44A, 44B) on each end of the center portion (42) bonded to the first side (32) of the wall of the structure adjacent to the slot. The first flexible member (40) further includes a plurality unidirectional reinforcing filaments (48) in a matrix material with the filaments being parallel to each other in the center portion (42) and fanning out from each other in each of the outer portions (44A, 44B). A second flexible member (50) having a periphery extending about the slot (36) and the outer portions of the first flexible member (40) is bonded thereto and to the first side (32) of the flexible wall of the structure.

L'invention concerne un dispositif de fixation conçu pour s'utiliser sur la paroi souple d'une structure. La fixation (24) comprend une fente (36) pratiquée dans la paroi (30) de la structure. Un premier élément souple (40) possède une partie centrale (42) repliée sur elle-même et constituant une boucle s'étendant à travers la fente (36) depuis un premier côté (32) de la paroi (30) et vers l'extérieur depuis le deuxième côté (34), ainsi que des parties extérieures en forme d'éventail (44A, 44B) sur chaque extrémité de la partie centrale (42), fixées au premier côté (32) de la paroi de la structure en position contiguë à la fente. Le premier élément souple (40) comprend, de plus, une pluralité de filaments de renforcement unidirectionnels (48) dans un matériau de matrice, lesdits filaments étant disposés parallèlement les uns par rapport aux autres dans la partie centrale (42) et s'écartant en éventail dans chacune des parties extérieures (44A, 44B). Un deuxième élément souple (50), dont la périphérie s'étend autour de la fente (36) et des parties extérieures du premier élément souple (40), est fixé audit élément (40) et au premier côté (32) de la paroi souple de la structure.
