Abstract
Abstract An improved heat sealed joint for a cushioned toilet seat of a construction in which a plastic skin encapsulates a cushion element and a rigid base by heat sealing a facing and sole sheet thereabout. The new heat sealed joint utilizes a back-up or reinforcing strip secured to the margins of the base so as to underlie lapped together portions of the facing and sole sheets during welding thereof whereby a three-element trihedral joint is effected instead of the usual two.
