Abstract
A detachable mobile seat includes a first part connected to a motor; a second part attached to the seat; and two links, each connected to the first part, the second part, and a wheel. The links transfer movement of the first part to the wheels. The first part includes a shaft connected to the motor, and two nuts disposed around the shaft that have screw threads in opposite directions and move along the shaft in response to operation of the motor. Each link includes a first link connected to the second part and to the nut, and a second link connected to the nut and to the wheel. The end of each second link that is nearest the wheel is rotatably connected to a connecting arm that has a rotating bar that rotates the wheel in response to operation of the links.
