Abstract

An adjustable armrest assembly provides for quick and easy height and tilt adjustments to the armrest. Generally, the armrest assembly disclosed herein includes a base, an armrest, and one or more shafts extending from the base and being pivotably coupled to the armrest. By moving the one or more shafts relative to the base, the height and/or tilt of the armrest relative to the base can be adjusted.

First claim

What is claimed is:

1. An armrest assembly for a seat, the armrest assembly comprising:
a base;
an armrest comprising an underside and an upper surface configured to support a user's arm;
a first shaft slidably coupled to the base and pivotably coupled to the underside of the armrest;
a second shaft non-slidably extending from the base and pivotably coupled to the underside of the armrest; and
a locking mechanism configured to reversibly lock the first shaft in a locked configuration relative to the base to prevent sliding of the first shaft relative to the base, wherein the locking mechanism is configured to reversibly release the first shaft in a released configuration relative to the base to allow sliding of the first shaft relative to the base, wherein the armrest comprises a graspable handle configured to actuate the locking mechanism between the locked configuration and the released configuration, wherein the locking mechanism comprises a first clamp ring disposed around the first shaft.

2. The armrest assembly of claim 1 , wherein the first shaft is pivotably coupled to a forward portion of the armrest and the second shaft is pivotably coupled to a rear portion of the armrest.

3. The armrest assembly of claim 1 , wherein the graspable handle is configured to actuate the first clamp ring.

4. The armrest assembly of claim 3 , further comprising a control cable extending from the graspable handle to the first clamp ring.

5. The armrest assembly of claim 1 , wherein the first shaft is threaded.

6. The armrest assembly of claim 5 , wherein the first clamp ring is threaded.

7. The armrest assembly of claim 5 , wherein the base defines a first slot, wherein the first shaft is configured to slide longitudinally within the first slot.

8. The armrest assembly of claim 7 , wherein the first slot is non-threaded.

9. The armrest assembly of claim 1 , wherein the first clamp ring comprises two portions coupled together via a spring element.
