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

Abstract: A stowable cabin attendant seat assembly includes a frame assembly mountable within a wall recess, a backrest mounted for reciprocating vertical translation within the frame assembly, a seat pan mounted for pivoting motion relative to the frame assembly, and at least one link connecting the seat pan to the backrest. The at least one link coordinates the seat pan and backrest motions such that upward lifting motion on the seat pan pushes the backrest vertically up for compact stowing and downward pivoting motion on the seat pan pulls the backrest vertically down.
