Abstract

A structural shroud for a passenger seat assembly includes a hollow body having a first end, a second end opposite from the first end, and a central cavity between the first end and the second end. In certain embodiments, the structural shroud may include a magnesium alloy and/or an aluminum alloy, and may be formed via casting, forging, and/or additive manufacturing, among others. In some embodiments, a base frame assembly for a passenger seat assembly includes a monolithic base frame having a first leg portion and a first tube portion integrally formed with the first leg portion.

First claim

That which is claimed is:

1. A method of producing a passenger seat assembly, the method comprising:
forming a structural shroud by casting or forging an aluminum alloy or a magnesium alloy into a first portion of the structural shroud and forming a second portion of the structural shroud via additive manufacturing, wherein the second portion comprises a lattice structure; and
joining the structural shroud with a secondary component of the passenger seat assembly;
wherein the first and second portions, at least partially, surround the secondary component with the first portion on one side of the secondary component and the second portion on another side opposite the one side.

2. The method of claim 1 , wherein the structural shroud is an upper spreader, wherein the secondary component is a lower spreader configured to receive at least one seat beam tube, and wherein joining the structural shroud with the secondary component comprises attaching the structural shroud to the lower spreader such that the structural shroud extends away from the lower spreader such that an end of the upper spreader is spaced apart from the lower spreader.

3. The method of claim 1 , wherein forming the structural shroud comprises forming the structural shroud with a central cavity extending through the structural shroud.

4. The method of claim 1 , wherein the structural shroud is an armrest, and wherein the secondary component is a spreader.
