    • A patient support device, such as a bed, includes a frame, a backrest or other platform movable with respect to the frame, and an actuator connecting the backrest to the frame. The actuator is configured to raise and lower, or otherwise move, the backrest or platform with respect to the frame. An actuator sensor is provided to sense movement of the actuator. A backrest sensor is provided to sense movement of the backrest. A controller is coupled to the actuator, the actuator sensor, and the backrest sensor. The controller is configured to stop the actuator from raising the backrest in response to a characteristic signal from the actuator sensor. The controller is further configured to stop the actuator from lowering the backrest in response to at least a characteristic signal from the backrest sensor. The characteristic signals are defined to prevent the backrest or platform from moving when obstructed or overloaded in order to reduce the chance of damage or injury.
    • 诸如床的患者支撑装置包括相对于框架可移动的框架,靠背或其他平台以及将靠背连接到框架的致动器。 致动器构造成相对于框架升高和降低或以其他方式移动靠背或平台。 提供致动器传感器以感测致动器的运动。 提供靠背传感器来感测靠背的运动。 控制器耦合到致动器,致动器传感器和靠背传感器。 控制器被配置为响应于来自致动器传感器的特征信号而停止致动器升高靠背。 控制器还被配置成响应于来自靠背传感器的至少一个特征信号而使致动器停止降低靠背。 定义特征信号,以防止靠背或平台在受阻或过载时移动,以减少损坏或受伤的机会。
