    • A support frame for use in a lift chair. In one embodiment, the support frame includes a base frame having longitudinally spaced transversely extending front and rear frame base rails; a first longitudinally extending side frame base rail connected to the front and rear frame base rails and a second longitudinally extending side frame base rail connected to the front and rear frame base rails, respectively, the first and second side frame base rails and the front and rear frame base rails being co-planar for supporting the lift chair on a surface; and a force balance member mounted to the rear frame base rail. The force balance member has a transversely extending base portion, a first arm portion extending from the base portion at a first angle αa, and an opposite, second arm portion extending from the base portion at a second angle αb.
    • 用于升降椅的支撑架。 在一个实施例中,支撑框架包括具有纵向间隔开的横向延伸的前框架和后框架基座轨道的基架; 连接到前框架基座和后框架基座的第一纵向延伸的侧框架基座和分别连接到前框架基座和后框架基座的第二纵向延伸的侧框架基座,第一和第二侧框架底座轨道 后框架基轨是共面的,用于将升降椅支撑在表面上; 以及安装到后框架基轨的力平衡构件。 力平衡构件具有横向延伸的基部,以第一角度αa从基部延伸的第一臂部分和以第二角度αb从基部延伸的相对的第二臂部分。
