Abstract

An armrest for a passenger seat has a forward end, an aft end opposite from the forward end, and a top surface extending from the forward end to the aft end. The top surface includes a first zone and a second zone, and a curvature of the first zone of the top surface is different from a curvature of the second zone of the top surface. In some examples, at least one of the first zone or the second zone has a concave curvature.

First claim

That which is claimed is:

1. An armrest for a passenger seat, the armrest comprising:
a forward end;
an aft end opposite from the forward end, wherein the aft end is configured to attach to the passenger seat such that the armrest is pivotable about a first axis;
a top surface, wherein the top surface comprises a first zone and a second zone, and wherein the first zone of the top surface comprises a concave curvature; and
at least first and second forearm supports pivotably coupled to the forward end of the armrest, wherein the at least first and second forearm supports is pivotable in a side-to-side direction relative to the top surface between a stowed position, in which the first and second forearm supports are adjacent and in contact with each other, and a deployed position, in which forward ends of the at least first and second forearm supports are spaced apart from each other, and wherein the at least first and second forearm supports at least partially forms the top surface and the top surface extends from the aft end to the at least first and second forearm supports.

2. The armrest of claim 1 , wherein at least a portion of the second zone is between the first zone and the forward end of the armrest.

3. The armrest of claim 1 , wherein the second zone of the top surface is proximate to the forward end of the armrest, and wherein a width of the second zone of the top surface at the forward end is greater than a width of the first zone of the top surface.

4. The armrest of claim 1 , wherein the second zone of the top surface is planar.

5. The armrest of claim 1 , wherein the second zone of the top surface comprises a concave curvature, and wherein the concave curvature of the first zone of the top surface is different from the concave curvature of the second zone of the top surface.

6. The armrest of claim 1 , wherein the armrest further comprises a first side extending between the forward end and the aft end and a second side opposite from the first side and extending between the forward end and the aft end, and wherein the first zone of the top surface has the concave curvature in a direction extending between the forward end and the aft end and in a direction extending between the first side and the second side.

7. An armrest for a passenger seat, the armrest comprising:
a forward end;
an aft end opposite from the forward end; and
a top surface, wherein the top surface comprises a first zone, a second zone, and a third zone, wherein a curvature of the first zone of the top surface is different from a curvature of the second zone of the top surface, wherein the third zone extends from the forward end to the aft end, and wherein a curvature of the third zone of the top surface is different from the curvature of the first zone of the top surface and different from the curvature of the second zone of the top surface; and
first and second forearm supports pivotably coupled to the forward end, wherein the first and second forearm supports pivotable in a side-to-side direction relative to the top surface between a stowed position, in which the first and second forearm supports are adjacent and in contact with each other, and a deployed position, in which forward ends of the first and second forearm supports are spaced apart from each other, and wherein the first and second forearm supports at least partially define the top surface which extends from the aft end to the forward ends of the first and second forearm supports.

8. The armrest of claim 7 , wherein the first zone of the top surface comprises a concave curvature and wherein the third zone of the top surface is planar.

9. The armrest of claim 7 , wherein the third zone of the top surface is proximate to the forward end of the armrest, and wherein a width of the third zone of the top surface at the forward end is greater than a width of the first zone of the top surface.

10. The armrest of claim 7 , wherein the armrest further comprises a first side extending between the forward end and the aft end and a second side opposite from the first side and extending between the forward end and the aft end, and wherein the first zone of the top surface comprises a concave curvature in a direction extending between the forward end and the aft end and in a direction extending between the first side and the second side.

11. An armrest for a passenger seat, the armrest comprising:
an aft end; and
at least first and second forearm supports, each of the at least first and second forearm supports comprising a forward end, wherein the at least first and second forearm supports is pivotable in a side-to-side direction relative to a top surface between a stowed position, in which the at least first and second forearm supports are adjacent and in contact with each other, and a deployed position, in which the forward ends of the at least first and second forearm supports are spaced apart from each other and pivotable about an upright pivot axis between the aft end and the forward end,
the top surface extending from the aft end to the forward end, wherein the top surface comprises at least a first zone and a second zone wherein a curvature of the first zone of the top surface is different from a curvature of the second zone of the top surface.

12. The armrest of claim 11 , wherein the first zone of the top surface is planar and wherein the second zone of the top surface comprises a concave curvature.

13. The armrest of claim 11 , wherein the first zone of the top surface comprises a concave curvature and wherein the second zone of the top surface comprises a concave curvature.

14. The armrest of claim 11 , wherein a first side and a second side extend between the forward end and the aft end, and wherein at least a portion of the first zone of the top surface is between the second zone of the top surface and the forward end.

15. The armrest of claim 14 , wherein at least one of the first and second forearm supports is pivotably coupled to a forward end of the armrest.

16. The armrest of claim 14 , wherein the second zone of the top surface comprises a concave curvature in a direction extending between the forward end and the aft end and in a direction extending between a first side and a second side.

17. The armrest of claim 11 , wherein the first zone comprises a first visual indicator and the second zone comprises a second visual indicator different from the first visual indicator.
