  • Adaptive seating system
    Patent number: 6055473
    Abstract: Adaptive seating comfort control automatically senses occupation of a seat, estimates attributes of the seat occupant, and generates and issues seating comfort control commands in response to the occupant attributes to provide for maximum seating comfort and to provide for a desired interaction with other control systems. Comfort control commands take the form of desired pressure commands for at least one fluid filled bladder within the seat and may be updated periodically during a period of seat occupation to account for change in position of the seat occupant or to reduce occupant muscle fatigue.
