  • Patent number: 7464949
    Abstract: A wheelchair wheel positioning system for providing an unobstructed path into and out of a wheelchair. The wheelchair wheel positioning system includes a frame member fastened to a wheelchair frame, an actuation member pivotably connected to both a frame bar and a rear wheel of the wheelchair and a stabilizer member utilized for lifting and maintaining the wheelchair in place. The actuation member pivotally connects at one end to the frame member and pivotally connects near the middle to a rear wheel of the wheelchair. The stabilizer member is affixed near the middle of the actuation member at a preferred angle. As the actuation member and rear wheel are rotated rearward, the stabilizer member contacts the floor surface to lift the rear wheel that the wheelchair wheel positioning system is attached to and stabilizes the wheelchair for entry and exit.
