A wheelchair includes a seat, one or more wheels and a seat weight sensing mechanism. The wheel includes a brake for stopping the wheel. The seat weight sensing mechanism is placed below the seat and is connected to the brake. When the seat is loaded by a weight more than a predetermined value, the seat weight sensing mechanism releases the brake to free the wheel. When the seat is not loaded by a weight more than a predetermined value, the brake stops the wheel. |
