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.
