    • 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.
    • 主动支撑组件(30)包括具有子框架(34)的框架组件(32)。 主动装置(36)包括具有附接到框架组件(42)的固定端(40)的柔性元件(38)。 每个有源器件(36)或柔性元件(38)的相对端还包括可移动端(42)。 电活性聚合物致动器(70)被组织成阵列(68),每个致动器(70)与柔性元件(38)对齐。 随着柔性元件(38)的膨胀,激活信号的增加使得相应的致动器(70)膨胀,并强制地延伸可动端部(42)。 活动的支撑组件可以用于床垫,覆盖物和座椅,以便响应于由乘客引起的外力的应用来调整它们。
