Abstract

A structural shroud assembly for a passenger seat includes a structural shroud having a first end, a second end opposite from the first end, and a central cavity between the first end and the second end. An armrest pivot may be supported at the first end of the structural shroud. In some cases, the structural shroud may be an armrest. In other cases, the structural shroud is an upper spreader for the passenger seat configured to support a seat back of the passenger seat, and a lower spreader configured to receive at least one seat beam tube is attached to the upper spreader.

First claim

That which is claimed is:

1 . A spreader assembly for a passenger seat, the spreader assembly comprising:
a lower spreader configured to receive at least one seat beam tube; and an upper spreader attached to the lower spreader and extending away from the lower spreader such that an end of the of the upper spreader is spaced apart from the lower spreader, wherein the upper spreader defines a central cavity extending through the upper spreader, and wherein the upper spreader is configured to support a seat back of the passenger seat.

2 . The spreader assembly of claim 1 , wherein the upper spreader comprises a first shroud and a second shroud attached to the first shroud, and wherein the first shroud and the second shroud together define the central cavity.

3 . The spreader assembly of claim 1 , wherein the lower spreader extends in a forward and aft direction, and wherein the upper spreader assembly extends in a vertical direction relative to the lower spreader.

4 . The spreader assembly of claim 1 , further comprising an armrest pivot supported at the end of the upper spreader spaced apart from the lower spreader.

5 . The spreader assembly of claim 4 , further comprising an interface support, wherein the interface support supports the armrest pivot at the end of the upper spreader spaced apart from the lower spreader.

6 . The spreader assembly of claim 1 , further comprising a table stop integrally formed with the upper spreader.

7 . The spreader assembly of claim 1 , wherein a cross-sectional shape of the lower spreader is different from a cross-sectional shape of the upper spreader.

8 . A structural assembly for a passenger seat, the structural assembly comprising:
a structural shroud comprising a first end, a second end opposite from the first end, and a central cavity between the first end and the second end, wherein the first end defines an opening to the central cavity; and an armrest pivot supported at the first end of the structural shroud.

9 . The structural assembly of claim 8 , wherein the structural shroud is an armrest.

10 . The structural assembly of claim 8 , wherein the structural shroud is an upper spreader for the passenger seat configured to support a seat back of the passenger seat, and wherein the structural assembly further comprises:
a lower spreader configured to receive at least one seat beam tube, wherein the upper spreader attached to the lower spreader, and wherein the lower spreader extends away from the upper spreader in a forward direction.

11 . The structural assembly of claim 8 , further comprising an interface support, wherein the interface support supports the armrest pivot at the first end of the structural shroud.

12 . The structural assembly of claim 8 , wherein the structural shroud comprises a first shroud and a second shroud attached to the first shroud, and wherein the first shroud and the second shroud together define the central cavity.

13 . A passenger seat assembly comprising a spreader assembly, the spreader assembly comprising:
a lower spreader extending in a forward direction and defining a forward-most portion of the spreader assembly; and an upper spreader attached to the lower spreader and extending in a vertical direction relative to the lower spreader, wherein the upper spreader defines a top-most portion of the spreader assembly, wherein the upper spreader is hollow, and wherein the upper spreader is configured to support a seat back of the passenger seat assembly.

14 . The passenger seat assembly of claim 13 , wherein a cross-sectional shape of the upper spreader is different from a cross-sectional shape of the lower spreader.

15 . The passenger seat assembly of claim 13 , further comprising the seat back supported by the upper spreader, and wherein the lower spreader is configured to attach to at least on seat beam tube.

16 . The passenger seat assembly of claim 13 , wherein the upper spreader comprises a first shroud and a second shroud attached to the first shroud, and wherein the first shroud and the second shroud together define a central cavity such that the upper spreader is hollow.

17 . The passenger seat assembly of claim 13 , wherein the upper spreader is attached to an aft portion of the lower spreader.

18 . The passenger seat assembly of claim 17 , wherein the upper spreader is an aft-most portion of the spreader assembly.

19 . The passenger seat assembly of claim 13 , further comprising an armrest pivot supported at an end of the upper spreader opposite from the lower spreader.

20 . The passenger seat assembly of claim 13 , further comprising a table stop integrally formed with the upper spreader.
