### Claim 9 (depends on 5)

The occupant support system of claim 5, wherein the comfort sling is arranged to extend from the upper arm support to the forearm support and the comfort sling is configured to support the full arm of the occupant to cause the occupant's elbow to be spaced apart from the rigid frame.

### Claim 10 (depends on 9)

The occupant support system of claim 9, wherein the comfort sling includes a soft cushion and a cushion support and the cushion support includes reinforcement rods that extend through the soft cushion in the longitudinal direction to rigidify the comfort sling.

### Claim 11 (depends on 1)

The occupant support system of claim 1, wherein the occupant support system is configured provide means for positioning the occupant's body in a neutral body position to establish a first reference axis defined by the occupant's shoulders and the occupant's hips when the occupant is viewed from the side and to cause the occupant's head to pivot forward so that the occupant's eyes face directly toward the point on the horizon and are aligned with the horizontal reference plane and the horizontal reference plane is less than about 20 degrees from the object line of sight.

### Claim 12 (depends on 11)

The occupant support system of claim 11, wherein the arm support positions the occupant's arm so that an angle between the occupant's upper arm and forearm is within a range of about 98 to about 146 degrees and an angle between the occupant's upper arm and the first reference axis is within a range of about 17 degrees to about 55 degrees.

### Claim 13 (depends on 12)

The occupant support system of claim 12, wherein the arm support positions the occupant's arm so that the angle between the occupant's upper arm and the occupant's forearm is about 122 degrees and the angle between the occupant's upper arm and the first reference axis is at about 36 degrees.

### Claim 14 (depends on 11)

The occupant support system of claim 11, wherein the arm support positions the occupant's upper arm to extend away from the occupant's body at an angle within a range of about 28 to about 50 degrees from a central axis defined by splitting the occupant when the occupant is viewed from above and the forearm support positions the occupant's forearm to extend inward from the occupant's upper arm toward the central axis at an angle within a range of about 29 to about 69 degrees.

### Claim 15 (depends on 14)

The occupant support system of claim 14, wherein the arm support positions the occupant's upper arm to extend away from the occupant's body at an angle of about 39 degrees from the central axis and the forearm support positions the occupant's forearm to extend inward from the occupant's upper arm toward the central axis at an angle of about 49 degrees.

### Claim 16 (depends on 4)

The occupant support system of claim 4, wherein the arm support is configured to move from an expanded configuration in which the upper arm support is arranged to extend away from the vehicle seat, the forearm support is arranged to extend away from the upper arm support, and a comfort sling is arranged to extend from the first end of the rigid frame to the second end of the rigid frame and is spaced apart from the rigid frame, to a partially-expanded configuration where the forearm support is pivoted inward toward the vehicle seat along a first hinge so that the forearm support rests on the upper arm support and the comfort sling is arranged between the upper arm support and the forearm support.

### Claim 17 (depends on 16)

The occupant support system of claim 16, wherein the arm support is configured to move from the partially-expanded configuration to a stored configuration, where the upper arm support is pivoted downward toward a seat bottom of the vehicle seat along a second hinge so that the arm support is aligned with a seat back of the vehicle seat.
