Abstract: A composite hinge is provided for the seat and the lid of a cushioned toilet seat. The hinge has three arms or leaves, (1) a bowl leaf adapted to be secured as by bolt to the rear of the porcelain bowl, (2) a forwardly extending arm or seat leaf adapted to be secured to the underside of the seat at the rearward end thereof, and (3) a second forwardly extending arm or lid leaf adapted to be secured to the underside of the lid at the rearward end thereof. The pivot point of the lid leaf is adjustable automatically relative to the seat leaf, thereby to accomodate the lid to cushioned toilet seats having different cushion thicknesses. The seat leaf is adjustable automatically in the vertical direction to accommodate the seat to bumpers of different thickness. The composite hinge is so designed that there is no stress on the hinge pins.
