Abstract

An additively manufactured strut device including a cylinder body (102) forming a chamber and a piston (108) having a first part disposed in the internal chamber and a second part disposed outside of the chamber. A first deformable element (118) formed as a lattice structure breaks to permit initial withdrawal of the piston (108) when a tensive threshold is met and a second deformable crushes during continued withdrawal of the piston (108). In further embodiments, a third deformable element formed as a lattice structure may be collocated with the second deformable element (122). The strut may be manufactured by an additive manufacturing process. Applications for the energy absorbing strut include aircraft seat frames among other applications.
