A vehicle comprising:

• a vehicle seat comprising a seat base structure and a seat back structure pivotally connected to the seat base structure, the seat back structure including a central adjustable region, an inboard side adjustable region adjacent the central adjustable region and a outboard side adjustable region located adjacent the central adjustable region, wherein the seat back structure includes a central proximity sensor located at the central adjustable region, an inboard side proximity sensor located at the inboard side adjustable region and an outboard side proximity sensor located at the outboard side adjustable region;
• a seat ECU that receives signals from the central proximity sensor, the inboard side proximity sensor and the outboard side proximity sensor that are indicative of respective occupant back locations with an occupant sitting in the vehicle seat;
• and
• a seat back structure adjustment apparatus comprising a central region adjustable member that adjusts a configuration of the central adjustable region, an inboard side adjustable member that adjusts a configuration of the inboard side adjustable region and an outboard side adjustable member that adjusts a configuration of the outboard adjustable region;
• wherein the seat ECU includes logic for controlling an actuator that moves one or more of the central region adjustable member, the inboard side adjustable member and the outboard side adjustable member based on one or more signals from the central proximity sensor, the inboard side proximity sensor and the outboard side proximity sensor.
