An improved toilet seat closure is described employing weight-driven cords or cables for pivoting forward and lowering a toilet seat and its lid without a loud noise upon flushing of the toilet. The seat and mechanism for achieving the automatic closing can be easily retrofitted to existing toilets without any unsightly or major modification of the toilet or tank. The mechanism employs a flexible cable or cord which runs through a tubular sleeve and extends under and behind the tank and over the rear lip of the tank so as to be substantially out of sight to the users. The cord or cable is connected to a weight in the tank (which weight has a specific gravity slightly higher than 1 ) so that on flushing the weight draws down the cord or cable a short distance. The cord also runs over a fixed pulley and runs free to the end of a pivoting arm extension from the seat member. The end points of arc of the end of the pivoting arm are so related to the fixed point that the falling weight causes the cable to initially pivot the arm and thus the seat member from its raised position forward to past its forward tipping or falling point. The seat thereby then pivots by gravity downward but is restrained and slowed by the cable and weight system as it approaches its down or closed position.
