## Abstract

A table assembly including a first arm attachable to a fixed structure, a second arm pivotally attached to the first arm, a third arm is pivotally attached to the second arm, and a table attached to the third arm. The second arm is configured to maintain the first arm and the third arm parallel as the first arm and the third arm pivot simultaneously relative to the second arm. The second arm includes a tension member configured to transfer tension along the second arm from the first arm to the third arm as the first arm and third arm pivot simultaneously relative to the second arm. The tension member may be further configured to transfer compression along the second arm from the third arm to the first arm as the first arm and third arm pivot simultaneously relative to the second arm.

## Claims

### Claim 1

A table assembly, comprising:
a first arm attachable to a fixed structure;
a second arm pivotally attached to the first arm;
a third arm pivotally attached to the second arm; and
a table attached to the third arm,
wherein the second arm is configured to maintain the first arm and the third arm parallel as the first arm and the third arm pivot simultaneously relative to the second arm to raise or lower the table;
wherein the second arm comprises a tension member configured to transfer tension along the second arm from the first arm to the third arm as the first arm and the third arm pivot simultaneously relative to the second arm; and
wherein the second arm comprises a side frame pivotally attached to the first arm and pivotally attached to the second arm, and wherein the tension member moves linearly relative to the side frame when the first arm and the third arm pivot simultaneously relative to the second arm.

### Claim 2 (depends on 1)

The table assembly of claim 1, wherein the second arm comprises a compression member configured to transfer compression along the second arm from the first arm to the third arm as the first arm and the third arm pivot simultaneously relative to the second arm.

### Claim 3 (depends on 1)

The table assembly of claim 1, wherein the second arm further comprises a compression member configured to transfer compression along the second arm from the first arm to the third arm as the first arm and third arm pivot simultaneously relative to the second arm, and the compression member moves linearly relative to the side frame when the first arm and the third arm pivot simultaneously relative to the second arm.

### Claim 4 (depends on 3)

The table assembly of claim 3, wherein the tension member and the compression member move linearly, relative to the side frame, in opposite directions simultaneously when the first arm and the third arm pivot simultaneously relative to the second arm.

### Claim 5 (depends on 1)

The table assembly of claim 1, wherein the tension member is further configured to transfer compression along the second arm from the third arm to the first arm as the first arm and third arm pivot simultaneously relative to the second arm.

### Claim 6 (depends on 1)

The table assembly of claim 1, wherein the tension member comprises a first contact surface engaging the first arm and a second contact surface facing the first contact surface and engaging the second arm.

### Claim 7 (depends on 6)

The table assembly of claim 6, wherein the first contact surface is involute and the second contact surface is involute.

### Claim 8 (depends on 6)

The table assembly of claim 6, wherein the first arm comprises a first rail engaging the first contact surface, the second arm comprises a second rail engaging the second contact surface, and the first rail and the second rail are trapped between the first contact surface and the second contact surface.

### Claim 9

An aircraft passenger seat assembly, comprising:
a passenger seat; and
a table assembly, including:
a first arm attached to the passenger seat;
a second arm pivotally attached to the first arm;
a third arm pivotally attached to the second arm; and
a table attached to the third arm,
wherein the second arm is configured to maintain the first arm and the third arm parallel as the first arm and third arm pivot simultaneously relative to the second arm to raise or lower the table;
wherein the second arm comprises a tension member configured to transfer tension along the second arm from the first arm to the third arm as the first arm and the third arm pivot simultaneously relative to the second arm; and
wherein the second arm comprises a side frame pivotally attached to the first arm and pivotally attached to the second arm, and the tension member moves linearly relative to the side frame when the first arm and the third arm pivot simultaneously relative to the second arm.

### Claim 10 (depends on 9)

The aircraft passenger seat assembly of claim 9, wherein the second arm comprises a compression member configured to transfer compression along the second arm from the first arm to the third arm as the first arm and the third arm pivot simultaneously relative to the second arm.

### Claim 11 (depends on 9)

The aircraft passenger seat assembly of claim 9, wherein the second arm further comprises a compression member configured to transfer compression along the second arm from the first arm to the third arm as the first arm and third arm pivot simultaneously relative to the second arm, and the compression member moves linearly relative to the side frame when the first arm and the third arm pivot simultaneously relative to the second arm.

### Claim 12 (depends on 11)

The aircraft passenger seat assembly of claim 11, wherein the tension member and the compression member move linearly, relative to the side frame, in opposite directions simultaneously when the first arm and the third arm pivot simultaneously relative to the second arm.

### Claim 13 (depends on 9)

The aircraft passenger seat assembly of claim 9, wherein the tension member is further configured to transfer compression along the second arm from the third arm to the first arm as the first arm and third arm pivot simultaneously relative to the second arm.

### Claim 14 (depends on 9)

The aircraft passenger seat assembly of claim 9, wherein the tension member comprises a first contact surface engaging the first arm and a second contact surface facing the first contact surface and engaging the second arm.

### Claim 15 (depends on 14)

The aircraft passenger seat assembly of claim 14, wherein the first contact surface is involute and the second contact surface is involute.

### Claim 16 (depends on 14)

The aircraft passenger seat assembly of claim 14, wherein the first arm comprises a first rail engaging the first contact surface, the second arm comprises a second rail engaging the second contact surface, and the first rail and the second rail are trapped between the first contact surface and the second contact surface.
