Abstract

Equipment and processes generate a seating solution by obtaining occupant data, calculating body dimensions from the occupant data, and calculating a best-fit body arrangement for an occupant. Occupant data may be obtained in various ways using available computational devices and software or by manually measuring the relevant dimensions on the occupant. A user interface for inputting occupant metrics and/or occupant measurements may be provided in a mobile terminal included in the vehicle or separate from the vehicle, thus giving users increased flexibility while maximizing simplicity and usability for the user or other personnel obtaining the data. Once an occupant'"'"'s best-fit body arrangement is determined, it may be altered by changing the predetermined criteria to achieve optimum comfort, safety, and therapeutic benefit as well as used for providing improved comfort on a continuous basis and/or in response to detected or predicted vehicle, road, or atmospheric conditions.

Claims

1. An occupant support system comprising

a vehicle seat including a seat bottom mounted to a vehicle frame included in a vehicle for movement relative to the vehicle frame, a seat back coupled to the seat bottom to pivot about a seat-back pivot axis relative to the seat bottom, and a seat-movement system coupled to the seat back and seat bottom to control movement of the seat back and seat bottom and

a configuration control system configured to receive an input including occupant data associated with an occupant and a computer configured to receive the occupant data, calculate external body dimensions using the occupant data, calculate internal body dimensions using at least the external body dimensions, and calculate a first body arrangement of the occupant using the internal body dimensions and predetermined criteria,

wherein the seat-movement system is configured to move the vehicle seat to the first body arrangement.

2. The occupant support system of claim 1, wherein the input is provided by a sensor.

3. The occupant support system of claim 1, wherein the input is provided by a user interface.

4. The occupant support system of claim 1, wherein the configuration control system is further configured to receive an input including vehicle-seat configuration data associated with a configuration of the vehicle seat relative to the vehicle frame.

5. The occupant support system of claim 1, wherein the configuration control system is further configured to receive an input including vehicle data associated with the vehicle.

6. The occupant support system of claim 5, wherein the computer is further configured to calculate a second body arrangement of the occupant using the predetermined criteria and the vehicle data and the seat-movement system is configured to move the vehicle seat to the second body arrangement.

7. The occupant support system of claim 6, wherein the configuration control system is further configured to receive an input including vehicle-seat configuration data associated with a configuration of the vehicle seat relative to the vehicle frame and the computer is further configured to limit movement of the vehicle seat relative to the vehicle frame using the vehicle data, the vehicle-seat configuration data, and predetermined criteria.

8. The occupant support system of claim 7, wherein the configuration control system is further configured to receive an input including environmental data associated with an environment surrounding the vehicle and the computer is further configured to limit movement of the vehicle seat relative to the vehicle frame using the vehicle data, the vehicle-seat configuration data, predetermined criteria, and the environmental data.

9. The occupant support system of claim 8, wherein the environmental data includes at least one of weather data and traffic data.

10. The occupant support system of claim 1, wherein the configuration control system is further configured to receive an input from a user interface including a manual adjustment of the seat-movement system and the computer is configured to calculate a second body arrangement using the manual adjustment, predetermined criteria, and the first body arrangement and the seat-movement system is configured to move the vehicle seat to the second body arrangement.

11. The occupant support system of claim 10, wherein the configuration control system is further configured to receive an input including vehicle-seat configuration data associated with a configuration of the vehicle seat relative to the vehicle frame and the computer is further configured to limit movement of the vehicle seat relative to the vehicle frame using the vehicle-seat configuration data and predetermined criteria.

12. The occupant support system of claim 11, wherein the configuration control system is further configured to receive an input including environmental data associated with an environment surrounding the vehicle and the computer is further configured to limit movement of the vehicle seat relative to the vehicle frame using the vehicle data, the vehicle-seat configuration data, predetermined criteria, and the environmental data.

13. An occupant support system comprising

a vehicle seat including a seat bottom mounted to a vehicle frame included in a vehicle for movement relative to the vehicle frame, a seat back coupled to the seat bottom to pivot about a seat-back pivot axis relative to the seat bottom, and a seat-movement system coupled to the seat back and seat bottom to control movement of the seat back and seat bottom and

a configuration control system including a sensor configured to obtain biometric data associated with an occupant and a computer configured to receive the biometric data, determine a physical condition of the occupant using the biometric data, and determine a first body arrangement using the biometric data and predetermined criteria,

wherein the seat-movement system is configured to move the vehicle seat to the first body arrangement.

14. The occupant support system of claim 13, wherein the sensor is included within the vehicle seat.

15. The occupant support system of claim 14, wherein the computer is further configured to determine information regarding blood flow of the occupant using the biometric data.

16. The occupant support system of claim 15, wherein the computer is further configured to determine the first body arrangement using the biometric data, blood flow information, and predetermined criteria.

17. The occupant support system of claim 13, wherein the configuration control system includes an input including occupant data associated with an occupant and the computer is further configured to receive the occupant data, calculate external body dimensions using the occupant data, calculate internal body dimensions using at least the external body dimensions, and calculate the first body arrangement of the occupant using the biometric data, internal body dimensions, and predetermined criteria.

18. The occupant support system of claim 17, wherein the occupant data includes anthropometric data.

19. The occupant support system of claim 13, further comprising a pneumatic system including a pneumatic bladder coupled to the vehicle seat and configured to support an occupant resting on the vehicle seat, a pressurized air source coupled to the pneumatic bladder to provide pressurized air to the bladder and coupled to the seat-movement system to receive commands from the seat-movement system, and a pressure sensor coupled to the pneumatic bladder and configured to sense air pressure in the bladder and coupled to the computer to communicate the sensed pressure to the computer.

20. The occupant support system of claim 19, wherein the computer is configured to command the seat-movement system to cause the pressurized air source to maintain the air pressure in the pneumatic bladder in a predetermined pressure range.

21. The occupant support system of claim 19, wherein the body arrangement includes a location and orientation of the seat bottom relative to the vehicle floor, a location and orientation of the seat back relative the seat bottom, and at least one of operation of a pneumatic system, heating, or cooling of the vehicle seat.
