Abstract
An improved toilet seat having a flush device, a bowl mount, a seat and a lid each having at least one locking member and a hinge pin pivotally holding the seat and lid to the bowl mount, a braking means for the seat and lid, the braking means being substantially tapered at one end, spiral-shaped from the tapered end, and substantially flat and resilient and adapted to friction grip the respective seat and lid hinge pins as either or both descend to a closed position, and closure initiating means adapted to move the toilet seat from an upright resting position when the toilet is flushed to a point substantially beyond a vertical center such that the natural weight of the toilet seat causes the toilet seat to descend whereupon the respective tapered ends friction grip the respective seat and lid hinge pins and coil and tighten therearound thereby braking the natural descent of the toilet seat while permitting the toilet seat to close.
