Abstract: front page image
(EN)The present invention relates to a separation fastener assembly comprising a nut (11) having a plurality of nut segments (11a, 11b, 11c, 11d), a movable element (17) which is movable from a first position, in which it restrains the nut segments (11a, 11b, 11c, 11d) from radial expansion, to a second position, in which it permits the nut segments (11a, 11b, 11c, 11d) to radially expand, a bolt (10) having one end coupled to the nut (11), and a retaining element (19) which is arranged to hold the nut (11) in place. The retaining element (19) comprises an energy absorbing portion (20) which is sleeve shaped and adapted to be permanently deformed by the movable element (17) when the movable element is moved from the first position to the second position.
(FR)La présente invention concerne un ensemble de fixation à séparation comprenant un écrou (11) comportant plusieurs segments d'écrou (11a, 11b, 11c, 11d), un élément amovible (17) qui est mobile entre une première position, dans laquelle il limite le déplacement radial des segments d'écrou (11a, 11b, 11c, 11d), et une seconde position, dans laquelle il permet aux segments d'écrou (11a, 11b, 11c, 11d) de se déplacer radialement, un boulon (10) ayant une extrémité couplée à l'écrou (11), et un élément de retenue (19) qui est disposé pour maintenir l'écrou (11) en place. L'élément de retenue (19) comprend une portion d'absorption d'énergie (20) qui est en forme de manchon et adaptée pour être déformée en permanence par l'élément mobile (17) lorsque l'élément mobile est déplacé de la première position à la seconde position.
