Abstract

An occupant support system includes a vehicle seat and an arm support. The vehicle seat supports an occupant in a vehicle while the vehicle is moving. The arm support supports the occupant's arm.

First claim

The invention claimed is:

1. An occupant support system for use in a vehicle, the occupant support system comprising
a vehicle seat coupled to a floor of the vehicle to position an occupant to cause a horizontal reference plane defined by the occupant's eyes and a point along the horizon to be established when the occupant is looking at the point along the horizon and
an arm support coupled to the vehicle seat and configured support an arm of the occupant while the occupant is holding an object and looking at the object to cause an object line of sight between the occupant's eyes and the object to be established and to cause the horizontal reference plane and the object line of sight to be within a field of view of the occupant when the occupant is viewing the object and the vehicle is moving,
wherein the arm support includes a rigid frame having a first end and a second end, the first end of the rigid frame is coupled to the vehicle seat and includes an upper arm support, the second end of the rigid frame is arranged to extend away from the vehicle seat and includes a forearm support,
wherein the arm support further includes a comfort sling arranged to extend from the first end of the rigid frame toward the second end of the rigid frame, and
wherein the comfort sling is movable between an un-deformed arrangement in which a top surface of the comfort sling is generally straight and a deformed arrangement in which the occupant's arm provides a load on the comfort sling to cause the top surface to move inward toward the occupant and have a curved shape.

2. The occupant support system of claim 1 , wherein the field of view of the occupant includes a peripheral view and the horizontal reference plane is less than about 25 degrees from the object line of sight.

3. The occupant support system of claim 2 , wherein the field of view of the occupant includes a peripheral view and the horizontal reference plane is less than about 15 degrees from the object line of sight.

4. The occupant support of claim 1 , wherein the comfort sling includes an inner surface arranged to extend downwardly from the top surface toward the seat bottom and face the occupant and an outer surfaced arranged to extend downwardly from the top surface and face opposite the inner surface and the outer surface is configured to engage the occupant's arm when in the deformed arrangement.

5. The occupant support of claim 4 , wherein the outer surface has a concave surface arranged to support and engage the occupant's arm when the comfort sling is in the deformed arrangement.

6. The occupant support system of claim 1 , 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.

7. The occupant support system of claim 6 , 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.

8. 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.

9. The occupant support system of claim 8 , 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.

10. The occupant support system of claim 9 , 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.

11. The occupant support system of claim 8 , 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.

12. 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 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.

13. The occupant support system of claim 1 , 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.

14. The occupant support system of claim 13 , 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.

15. The occupant support system of claim 1 , wherein the arm support further includes a comfort sling extending from the second end of the rigid frame to the vehicle seat and coupled to the vehicle seat in spaced apart relation to the first end of the rigid frame.

16. An occupant support system for use in a vehicle, the occupant support system comprising
a vehicle seat coupled to a floor of the vehicle to position an occupant to cause a horizontal reference plane defined by the occupant's eyes and a point along the horizon to be established when the occupant is looking at the point along the horizon and
an arm support coupled to the vehicle seat and configured to support an arm of the occupant while the occupant is holding an object and looking at the object to cause an object line of sight between the occupant's eyes and the object to be established and to cause the horizontal reference plane and the object line of sight to be within a field of view of the occupant when the occupant is viewing the object and the vehicle is moving,
wherein the arm support includes a rigid frame having a first end and a second end, the first end of the rigid frame is coupled to the vehicle seat and includes an upper arm support, the second end of the rigid frame is arranged to extend away from the vehicle seat and includes a forearm support, and
wherein the rigid frame is configured to pivot ab
