Abstract: An apparatus for automatically raising a toilet seat when the toilet is flushed includes a toilet tank pivotally mounted on the bowl and a spring connected between the toilet tank and seat. A weight is attached to the spring. When the toilet seat is manually lowered, the spring flips to the upward position and holds the seat down. When the toilet is flushed, the decreasing water level in the tank changes the center of gravity of the tank and causes it to pivot, thereby flexing the spring in the opposite direction, with the aid of an attached counterweight, and raising the seat.
