摘要： A standing wheelchair includes a base frame, a pair of front driveable wheels connected to the front end of the frame, and a pair of rear wheels connected to the rear end of the frame. A seat assembly is connected to the front end of the frame and includes a seat portion that is pivotable between a generally horizontal, seated position and a raised, angled standing position. The seat portion pivots about a central stub pivot shaft located at the front thereof, with the stub pivot shaft being vertically offset above the seat portion. An actuator is connected between the front end of the seat assembly and the rear end of the seat assembly to actuate the seat portion between the seated and standing positions. An adjustable knee support assembly is connected to the front end of the seat assembly and is located behind the axles of the front wheels, and a footrest plate is connected to the frame at the front end between the front pair of wheels. By offsetting the stub pivot shaft above the seat portion, the pivot axis of the seat portion is located between the user's knees, thereby reducing shear on the user. Further, the seat assembly is designed so as to be easily removable as a single unit from the base frame, to allow the use of different seat assemblies on the base frame.
