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.

3. The occupant support system of claim 2, wherein the vehicle seat includes a seat bottom configured to be 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.

4. The occupant support system of claim 3, wherein the interface is further configured to obtain vehicle data associated with the vehicle seat and the computer is further configured to calculate a best-fit seating solution using the best-fit body arrangement, the vehicle data, and the predetermined criteria, communicate the best-fit seating solution to the seat-movement system to cause the seat bottom and seat back to move to positions that cause the best-fit seating solution of the vehicle seat to be established, and communicate the best-fit seating solution to the pneumatic system to cause the pneumatic bladder to be in the predetermined pressure range.

5. The occupant support system of claim 4, further comprising a prediction system including a GPS unit configured to determine a position of a vehicle relative to earth and a mapping unit coupled to the GPS unit to receive the position of the vehicle and determine a predicted future position of the vehicle relative to earth as the vehicle moves along a path and the mapping unit is coupled to the computer to send corresponding predicted future-position data to the computer.

6. The occupant support system of claim 5, wherein the computer is further configured to calculate a revised best-fit seating solution using the predicted future-position data, the best-fit seating solution, and the vehicle data, communicate the revised best-fit seating solution to the seat-movement system to cause the seat bottom and seat back to move to a revised best-fit arrangement, and communicate the revised best-fit seating solution to the pneumatic system to cause the pneumatic bladder to be in the predetermined pressure range.
