    摘要： A chair for supporting a patient includes a base frame including a staging frame and a lower frame. The staging frame is mounted for vertical movement relative to the lower frame. An intermediate frame is coupled to the base frame for pivoting movement relative to the base frame about a generally horizontal transverse axis. An articulated patient support is mounted to the intermediate frame. The patient support includes longitudinally spaced back, seat, and leg sections mounted to the intermediate frame for movement relative to one another and relative to the intermediate fame. The back, seat and leg sections are movable relative to the base tame about the horizontal transverse axis. A hydraulic system includes a first hydraulic cylinder actuating vertical movement of the staging frame relative to the lower frame, a second hydraulic cylinder actuating movement of the leg section relative to the seat section, and a pump actuating both the first and second hydraulic cylinders.

    摘要翻译： 用于支撑患者的椅子包括包括分段框架和下框架的基架。 分段架安装成相对于下框架垂直移动。 中间框架联接到基座框架，用于围绕基本水平的横向轴线相对于基座枢转运动。 铰接的患者支撑件安装到中间框架。 患者支架包括安装在中间框架上的相对于彼此和相对于中间名流相对运动的纵向间隔的后部，座椅和腿部。 背部，座椅和腿部部分相对于基于水平横向轴线的基座可移动。 液压系统包括第一液压缸，其致动分段框架相对于下框架的垂直运动，第二液压缸致动腿部相对于座部的运动，以及泵致动第一和第二液压缸。
