Abstract
A powered wheelchair for disabled persons is provided that has a center frame that has a first end and a second end. The wheelchair further has a seat support coupled to the center frame between the first and second ends. A pair of rear stabilizing wheels is connected to the center frame near the first end. The wheelchair further includes a drive assembly that is removably coupled to the center frame near the second end. The drive assembly has a pair of drive wheels that each have a motor operably connected thereto. A coupling mechanism is associated with the frame and the drive assembly that removably couples the frame to the drive assembly. The coupling mechanism is applicable and releasable by hand without the use of any tools. A power source is removably held on the center frame generally between the first and second ends, and is electrically connected to each of the motors. A seat assembly is removably coupled to the seat support that extends upwardly above the center frame. Finally, a controller is provided that allows operation of the drive assembly to be controlled. The controller is removably coupled to the seat assembly.
