ABSTRACT:
A seat assembly includes a seat defining an outer seating surface. An adjustment mechanism is mounted on the seat and includes a member movable relative to the seating surface for altering the contoured shape of the seating surface. A sensor is mounted on the seat. The sensor detects the location of an applied force acting on the seating surface by an occupant seated on the seat back and detects an applied pressure distribution of the force exerted on the seating surface. The sensor supplies a signal indicative of the location of the applied force and the applied pressure distribution of the force. A controller receives the signal and is operable by a seat occupant for storing information corresponding to the location of the applied force and the applied pressure distribution of the force. The controller is operable to move the member by the adjustment mechanism from an initial position to a subsequent position dependent on a subsequent detection of a location of a second applied force and an applied pressure distribution of the force detected by the sensor.
