Title (EN) AN ENERGY-ABSORBING STRUCTURE FOR A TETHER LINE, AND A TETHER LINE INCORPORATING THE SAME
(FR) STRUCTURE D'ABSORPTION D'ÉNERGIE POUR UNE LIGNE D'ATTACHE, ET LIGNE D'ATTACHE COMPRENANT CELLE-CI
Abstract:
(EN) An energy-absorbing structure (4) for a tether line comprises a helical spring (5) and a first connector (6) for securing a first end of the helical spring to a first fastener (such as a support cable section 2, an eye bolt 18 or an eye nut 18a). The first connector (6) has an externally threaded portion (11) for threadedly receiving the first end of the helical spring. A sleeve (8) is provided on the connector, extending over at least part of the first end of the helical spring and the external threaded portion of the connector, for retaining the helical spring on the connector. Additionally or alternatively, the connector comprises a tapered portion (11a) extending from the inner end of the externally threaded portion.
(FR) La présente invention concerne une structure d'absorption d'énergie (4) destinée à une ligne d'attache et comprenant un ressort hélicoïdal (5) et un premier raccord (6) pour fixer une première extrémité du ressort hélicoïdal à un premier élément de fixation (tel qu'une section de câble de support (2), un boulon à œil (18) ou un écrou à œil (18a)). Le premier raccord (6) présente une partie à filetage externe (11) pour recevoir par filetage la première extrémité du ressort hélicoïdal. Un manchon (8) est disposé sur le raccord, s'étendant sur au moins une partie de la première extrémité du ressort hélicoïdal et de la partie à filetage externe du raccord, pour retenir le ressort hélicoïdal sur le raccord. En outre ou en variante, le raccord comprend une partie effilée (11a) s'étendant à partir de l'extrémité interne de la partie à filetage externe.
