Abstract

Claims (63)

1. A shared armrest comprising:

at least one cam;

at least one extendable divider;

a stationary shaft;

a rotatable armrest pad; and

a locking mechanism,

wherein:

the rotatable armrest pad defines a first superior surface and a second superior surface, the second superior surface being wider than the first superior surface;

the rotatable armrest pad configured to rotate about the stationary shaft from a first configuration, where the first superior surface is disposed at a top of the shared armrest, to a second configuration, where the second superior surface is disposed at the top of the shared armrest;

the locking mechanism is configured to releasable retain the rotatable armrest pad in either the first configuration or the second configuration;

the at least one extendable divider is configured to translate radially through an opening defined by the second superior surface; and

the at least one cam is configured to direct the radial translation of the extendable divider as the rotatable armrest pad is rotated.

2. The shared armrest of claim 1 , wherein the locking mechanism comprises:

a button partially disposed within the stationary shaft; and

a biasing element configured to bias the button toward a locking configuration.

3. The shared armrest of claim 2 , wherein:

the locking mechanism further comprises one or more locking protrusions, each configured to engage a locking recess; and

the armrest pad comprises an internal structure defining a plurality of locking recesses disposed periodically about the stationary shaft, each configured to engage a locking protrusion of the locking mechanism.

4. The shared armrest of claim 3 , wherein the plurality of locking recesses are disposed every 90° about the stationary shaft.

5. The shared armrest of claim 1 , wherein the second superior surface comprises a curved profile.

6. The shared armrest of claim 1 , wherein the second superior surface comprises an angled profile defining a peak along a centerline.

7. An aircraft seat comprising:

at least one shared armrest comprising:

a stationary shaft;

a rotatable armrest pad; and

a locking mechanism comprising:

a button partially disposed within the stationary shaft; and

a biasing element configured to bias the button toward a locking configuration,

wherein:

the rotatable armrest pad defines a first superior surface and a second superior surface, the second superior surface being wider than the first superior surface;

the rotatable armrest pad configured to rotate about the stationary shaft from a first configuration, where the first superior surface is disposed at a top of the shared armrest, to a second configuration, where the second superior surface is disposed at the top of the shared armrest;

the locking mechanism is configured to releasable retain the rotatable armrest pad in either the first configuration or the second configuration;

the locking mechanism further comprises one or more locking protrusions, each configured to engage a locking recess; and

the armrest pad comprises an internal structure defining a plurality of locking recesses disposed periodically about the stationary shaft, each configured to engage a locking protrusion of the locking mechanism.

8. The aircraft seat of claim 7 , wherein the plurality of locking recesses are disposed every 90° about the stationary shaft.

9. The aircraft seat of claim 7 , further comprising:

at least one cam; and

at least one extendable divider,

wherein:

the at least one extendable divider is configured to translate radially through an opening defined by the second superior surface; and

the at least one cam is configured to direct the radial translation of the extendable divider as the rotatable armrest pad is rotated.

10. The aircraft seat of claim 7 , wherein the second superior surface comprises a curved profile.

11. The aircraft seat of claim 7 , wherein the second superior surface comprises an angled profile defining a peak along a centerline.

12. An armrest comprising:

at least one cam;

at least one extendable divider;

a stationary shaft;

a rotatable armrest pad; and

a locking mechanism,

wherein:

the rotatable armrest pad defines a first superior surface and a second superior surface, the second superior surface being wider than the first superior surface;

the rotatable armrest pad configured to rotate about the stationary shaft from a first configuration, where the first superior surface is disposed at a top of the shared armrest, to a second configuration, where the second superior surface is disposed at the top of the shared armrest;

the locking mechanism is configured to releasable retain the rotatable armrest pad in either the first configuration or the second configuration;

the at least one extendable divider is configured to translate radially through an opening defined by the second superior surface; and

the at least one cam is configured to direct the radial translation of the extendable divider as the rotatable armrest pad is rotated.

13. The armrest of claim 12 , wherein the locking mechanism comprises:

a button partially disposed within the stationary shaft; and

a biasing element configured to bias the button toward a locking configuration.

14. The armrest of claim 13 , wherein:

the locking mechanism further comprises one or more locking protrusions, each configured to engage a locking recess; and

the armrest pad comprises an internal structure defining a plurality of locking recesses disposed periodically about the stationary shaft, each configured to engage a locking protrusion of the locking mechanism.

15. The armrest of claim 12 , wherein the second superior surface comprises a curved profile.

16. The armrest of claim 12 , wherein the second superior surface comprises an angled profile defining a peak along a centerline.
