Abstract

An armrest assembly comprising a secondary armrest assembly is disclosed that can be deployed from a stowed and nested position beneath a primary armrest, with the secondary armrest assembly comprising a plurality of articulable and pivotable components, a seating assembly comprising the present armrest assembly, and vehicles configured to comprise the present armrest and seating assembly.

First claim

What is claimed is:

1. An armrest assembly comprising:
a primary armrest assembly, said primary armrest assembly comprising:
a primary armrest first surface and a primary armrest second surface, said primary armrest assembly further comprising a primary armrest proximal end and a primary armrest distal end, said primary armrest proximal end in communication with a seat assembly;
a secondary armrest assembly, said secondary armrest assembly comprising:
a secondary armrest front link, said secondary armrest front link comprising a secondary armrest front link first surface, a secondary armrest front link second surface, a secondary armrest front link proximal end and a secondary armrest front link distal end, said secondary armrest front link proximal end comprising a secondary armrest front link proximal end flange, said secondary armrest front link proximal end flange comprising a secondary armrest front link proximal end flange through opening;
a secondary armrest intermediate link, said secondary armrest intermediate link comprising a secondary armrest intermediate link proximal end comprising a secondary armrest intermediate proximal end flange, and a secondary armrest intermediate link distal end, said secondary armrest intermediate link distal end comprising at least one intermediate link distal end flange configured to movably and pivotably engage the secondary armrest front link proximal end flange; and
an armrest assembly end link, said armrest assembly end link comprising an armrest assembly end link proximal end comprising an armrest assembly end link proximal end flange, said armrest assembly end link further comprising an armrest assembly end link distal end comprising an armrest assembly end link distal end flange, said armrest assembly end link distal end configured to movably and pivotable engage the secondary armrest intermediate link proximal end flange, said armrest assembly end link proximal end configured to engage the seat assembly.

2. The armrest assembly of claim 1 , wherein the secondary armrest assembly is configured to move from a secondary armrest assembly stowed position immediately beneath the primary armrest assembly to a secondary armrest assembly deployed position laterally adjacent to the primary armrest assembly.

3. The armrest assembly of claim 2 , wherein the secondary armrest assembly in the secondary armrest assembly stowed position is configured to movably nest beneath the primary armrest assembly.

4. The armrest assembly of claim 2 , wherein the secondary armrest front link first surface comprises a secondary armrest cushion layer first section, said secondary armrest intermediate link comprises a secondary armrest cushion layer second section, and said primary armrest first surface comprises a primary armrest assembly cushion layer.

5. The armrest assembly of claim 2 , wherein, in the secondary armrest assembly deployed position, the secondary armrest front link is positioned at a secondary armrest front link average height, said secondary armrest front link average height varying from a primary armrest assembly average height.

6. The armrest assembly of claim 1 , wherein the secondary armrest assembly further comprises a secondary armrest front link extender, said secondary armrest front link extender configured to extend to a selected extended distance outwardly from the secondary armrest front link distal end.

7. The armrest assembly of claim 1 , wherein the primary armrest assembly has a first average width perpendicular to a primary armrest longitudinal axis, and the secondary armrest front link has a second average width perpendicular to a secondary armrest front link longitudinal axis, said first average width greater than or equal to the second average width.

8. The armrest assembly of claim 2 wherein the secondary armrest front link first surface comprises a secondary armrest front link first surface area, and wherein the entirety of said secondary armrest front link first surface area is exposed in the secondary armrest assembly deployed position.

9. The armrest assembly of claim 1 , wherein said secondary armrest intermediate link proximal end flange is configured to movably engage with the armrest assembly end link distal end, said secondary armrest intermediate link configured to movably pivot about the armrest assembly end link distal end.

10. The armrest assembly of claim 1 , wherein the secondary armrest front link proximal end flange is configured to movably engage with the secondary armrest intermediate link distal end, said secondary armrest front link proximal end flange further configured to movably pivot about the secondary armrest intermediate link distal end.

11. A seat assembly comprising the armrest assembly of claim 1 .

12. A passenger vehicle comprising the armrest assembly of claim 1 .

13. The passenger vehicle of claim 12 , wherein the passenger vehicle is selected from the group consisting of:
a crewed aircraft, an uncrewed aircraft, a crewed spacecraft, an uncrewed spacecraft, a crewed rotorcraft, an uncrewed rotorcraft, a crewed terrestrial vehicle, an uncrewed terrestrial vehicle; a crewed surface water borne vehicle, an uncrewed waterborne vehicle, a crewed sub-surface water borne vehicle, an uncrewed sub-surface water borne vehicle, a satellite, and combinations thereof.

14. An aircraft comprising the armrest assembly of claim 1 .

15. The armrest assembly of claim 1 , said secondary armrest assembly in communication with the armrest assembly end link, said armrest assembly end link proximal end configured to engage a seat frame.

16. A method for installing a seat assembly into a passenger vehicle, said method comprising:
installing a seat assembly into a passenger vehicle, said seat assembly comprising an armrest assembly, said armrest assembly comprising:
a primary armrest assembly, said primary armrest assembly comprising a primary armrest assembly first surface and a primary armrest assembly second surface, said primary armrest assembly further comprising a primary armrest proximal end and a primary armrest distal end;
a secondary armrest assembly, said secondary armrest assembly comprising a secondary armrest front link, said secondary armrest front link comprising a secondary armrest front link first surface and a secondary armrest front link second surface, said secondary armrest front link further comprising a secondary armrest front link proximal end and a secondary armrest front link distal end, said secondary armrest front link proximal end comprising a secondary armrest front link proximal end flange, said secondary armrest front link proximal end flange comprising a secondary armrest front link proximal end flange through opening, said secondary armrest assembly further comprising:
a secondary armrest intermediate link, said secondary armrest intermediate link comprising a secondary armrest intermediate link proximal end and a secondary armrest intermediate link distal end, said secondary armrest intermediate link distal end comprising a secondary armrest intermediate link distal end flange configured to movably engage the secondary armrest front link proximal end flange; and

an armrest assembly end link, said armrest assembly end link comprising an armrest assembly end link proximal end and an armrest assembly end link distal end, said armrest assembly end link distal end configured to movably engage the secondary armrest intermediate link proximal end flange, said armrest assembly end link proximal end configured to engage at least one of the seat assembly and a seat frame.
