An improved vehicle seat assembly (20) for mounting on the frame (F) of a vehicle driver's seat (s) including a polymer support plate (22) attached to the frame, a polyurethane foam base (24) on the support, an inflatable air cell cushion (26) on the base and an elastic cover (28). The inflatable air cell cushion (26) includes individual inflation zones (51) each comprised of individual interconnected inflation cells (52). The zones are normally isolated from each other. A center zone (51) having a preset inflation pressure is positioned under the ischial area of the driver. Front, back and side bolster zones provide front-to-back and side-to-side support. The individual air cells (52) of the center zone (51) are interconnected by a serpentine airflow path of reduced area to enhance the vibration and shock absorption characteristics of the zone. |
