ABSTRACT:
A weather strip for mounting relative to a door opening in an automobile includes an elongated body including a longitudinal trim portion of a U-shaped cross-section for being fitted on a peripheral flange formed on the periphery of the door opening, a hollow seal portion formed on an outer face of one of opposed arms of the trim portion, and a sealing lip for sealing engagement at its distal edge with a surface defining the door opening. A door of the automobile is adapted to be sealingly engaged at its peripheral edge portion with the seal portion. The strip body includes two straight elements of rubber and a corner element of molded rubber interconnecting the straight elements at their one ends and molded integrally therewith. The sealing lip of the straight element is formed on one end of the one arm of the trim portion. The seal portion of the corner element has one longitudinal edge portion disposed in spaced, opposed relation to the one end of the one arm of the trim portion of the corner element at a region intermediate opposite ends of the seal portion to form a longitudinal opening therebetween. The one longitudinal edge portion is integrally continuous with the sealing lip of each straight element so as to serve as the sealing lip of the corner portion. The longitudinal opening is used for removing a core from the corner element after the molding of the corner element.
