    • A wheelchair apparatus is provided for selectively positioning the operator from a sitting position to a standing position or a reclining position. The wheelchair apparatus includes a frame for supporting the operator's body in a reclined, sitting, and standing position. A single positioning actuator is used to selectively move the operator in the frame. A programmable controller controls the operation of both the chassis drive motors and the positioning actuator. The frame and chassis components are interconnected to achieve the desired positioning with a minimum number of electro-mechanical components. A sliding back frame is provided to eliminate shear forces on the back of the operator. The foot rest and frame are shifted towards the rear of the wheelchair when the operator is moved to a standing position such that the weight of the operator is over the axis of the large front wheels. The operator is still in a favorable position for access to items in front of the wheelchair, and the stability of the wheelchair is increased. The batteries are mounted on a slidable tray which is mechanically interfaced with the positioning of the main frame for additional weight distribution control. A shock absorber is attached to the back frame to minimize any instability in the back of the apparatus and to provide additional lifting force in the reclining position. A parallel linkage arm is provided for moving the control station to the side of the wheelchair.
    • 提供一种轮椅装置,用于将操作者从就座位置或倾斜位置选择性地定位。 轮椅装置包括用于以倾斜,坐着和站立位置支撑操作者的身体的框架。 使用单个定位致动器来选择性地将操作者移动到框架中。 可编程控制器控制底盘驱动电机和定位执行器的操作。 框架和底盘部件互连,以最少数量的机电部件实现所需的定位。 提供滑动后框架以消除操作者背面的剪切力。 当操作员移动到站立位置时,脚踏板和框架朝向轮椅的后部移动,使得操作者的重量超过大前轮的轴线。 操作者仍然可以利用轮椅前方的物品,轮椅的稳定性提高。 电池安装在可滑动的托盘上,该托盘机械地与主框架的定位接合,用于额外的重量分配控制。 减震器附接到后框架,以使设备背面的任何不稳定性最小化,并在倾斜位置提供额外的提升力。 提供一个平行的连杆臂,用于将控制台移动到轮椅侧面。
