Zusammenfassung:	An active support assembly (30) includes a frame assembly (32) having subframes (34). Active devices (36) includes a flexible element (38) having a stationary end (40) attached to the frame assembly (42). An opposing end of each of the active devices (36) or flexible elements (38) also include a movable end (42). Electroactive polymer actuators (70) are organized into an array (68), with each actuator (70) aligned with a flexible element (38). Increases in the level of the activation signals cause the corresponding actuators (70) to expand, and forcibly extend the movable ends (42), with expansion of the flexible elements (38). The active support assemblies can be used with mattresses, overlays and seating for purposes of adjusting the same in response to the application of external forces caused by an occupant.
