Beschreibung
Zusammenfassung:	A connecting link for connecting first and second components such as an aircraft seat leg and a track fastener. The link includes a helical middle portion forming an interior space in which an energy attenuator is positioned. In embodiments, the energy attenuator includes inner and outer cylindrical bodies that operate in translation upon a deformation of a lattice structure configured to deform when at least one of a compressive threshold and a tensive threshold is met. In embodiments, the energy attenuator receives part of one of the first and second components. The connecting link may be manufactured by an additive manufacturing process and used in an aircraft leg assembly to save weight and absorb impact energy on the leg.
