Passenger seat with close-out shroud

1. A passenger seat comprising:

a spreader assembly;

an arm rest assembly pivotally coupled to the spreader assembly;

a close-out shroud comprising:

a flame retardant material with a fatigue resistance that exceeds 50,000 cycles before failure; and

at least one living hinge formed within the flame retardant material;

wherein the close-out shroud is coupled to the arm rest assembly and the spreader assembly so that the at least one living hinge is positioned to articulate with the pivotal movement of the arm rest assembly over an entire range of motion of the arm rest assembly.

2. The passenger seat of claim 1 , wherein the at least one living hinge is formed as a thinned or cut section of the flame retardant material.

3. The passenger seat of claim 1 , wherein the flame retardant material is polypropylene or polyethylene.

4. The passenger seat of claim 1 , wherein the flame retardant material has a high melt flow rate greater than 2 g/10 min.

5. The passenger seat of claim 1 , wherein the fatigue resistance exceeds 75,000 cycles before failure.

6. The passenger seat of claim 1 , wherein the flame retardant material comprises a plurality of living hinges.

7. The passenger seat of claim 1 , wherein the flame retardant material comprises a pair of prongs with snap-fit hooks to couple the close-out shroud to the spreader assembly.

8. A passenger seat comprising:

a spreader assembly comprising a cam;

an arm rest assembly comprising a pivot pin;

wherein the arm rest assembly is pivotally coupled to the spreader assembly;

a close-out shroud comprising:

a flame retardant material comprising at least one living hinge;

wherein the close-out shroud is coupled to the arm rest assembly and the spreader assembly;

wherein the close-out shroud substantially encloses a location where the arm rest assembly is supported in a deployed position by the spreader assembly such that the pivot pin rests on the cam; and

wherein the at least one living hinge is configured to articulate through greater than 50,000 cycles before failure.

9. The passenger seat of claim 8 , wherein the at least one living hinge is formed as a thinned or cut section of the flame retardant material.

10. The passenger seat of claim 8 , wherein the flame retardant material is polypropylene or polyethylene.

11. The passenger seat of claim 8 , wherein the flame retardant material has a high melt flow rate greater than 2 g/10 min.

12. The passenger seat of claim 8 , wherein the flame retardant material comprises a plurality of living hinges.

13. The passenger seat of claim 8 , wherein the flame retardant material comprises a pair of prongs with snap-fit hooks to couple the close-out shroud to the spreader assembly.

14. The passenger seat of claim 8 , wherein an adjustable cam attached to the spreader assembly supports the arm rest assembly in the deployed position.

15. A passenger seat comprising:

a spreader assembly comprising a cam;

an arm rest assembly comprising an arm rest and a pivot pin, wherein the arm rest is pivotally coupled to the spreader assembly and configured to rotate between a stowed and a deployed position, wherein the pivot pin contacts the cam when the arm rest is in the deployed position; and

a close-out shroud comprising

an enclosure portion;

a coupling portion; and

at least one living hinge positioned between the enclosure portion and the coupling portion;

wherein the coupling portion is coupled to the spreader assembly and the enclosure portion extends into the arm rest so that the at least one living hinge is configured to articulate with the pivotal movement of the arm rest so that the close-out shroud substantially encloses an articulating opening between the pivot pin and the cam.

16. The passenger seat of claim 15 , wherein the at least one living hinge is formed as a thinned or cut section of a flame retardant material forming both the enclosure portion and the coupling portion.

17. The passenger seat of claim 16 , wherein the flame retardant material is polypropylene or polyethylene.

18. The passenger seat of claim 15 , wherein the at least one living hinge is configured to articulate through greater than 50,000 cycles before failure.

19. The passenger seat of claim 15 , wherein the coupling portion comprises a pair of prongs with snap-fit hooks that couple the close-out shroud to the spreader assembly.
