Abstract: An automatic toilet seat closing apparatus that operates on a controlled release of air. A control cylinder coupled to a seat closure member is secured to a conventional toilet bowl by placement of a universal support base positionable beneath the coupling hinge used by the seat. A water sensor is available for placement in a conventional water closet allowing release of air when the water level drops due to flushing of the toilet bowl. Alternatively, the apparatus will allow a controlled lowering of the toilet seat allowing the apparatus to be coupled to toilet bowls having water savers or non-conventional water closets such as those found on motor homes and boats. In addition, the device may be integrated into new toilet structures thereby eliminating the need for a separate support base.
