The present invention relates to an opening leaf upper module of this type particularly comprising a rigid frame and a flexible weather strip. The method of manufacturing an opening leaf upper module according to the invention, comprising a molded frame based on at least one thermoplastic polymer and a molded weather strip secured to the frame and based on at least one elastomer, comprises a step whereby a moving-platen mold or alternatively transfer molding is used to perform multiple-shot injection molding of materials that are intended to form the frame and the strip which are injected in succession, the elastomer being a thermoplastic elastomer compatible with this thermoplastic polymer, so as to obtain the module formed as a single piece. For preference, the strip comprises a continuous wiping lip for wiping the glass panel and an interface lip for interfacing with the bodywork of the vehicle, and the frame has a longitudinal hollow.
Opening leaf upper module intended to be mounted at a the periphery of a glass panel of a vehicle, said module comprising a molded frame predominantly made of at least one thermoplastic polymer and a molded weather strip secured to said frame and predominantly made of at least one elastomer, wherein said module is molded by multiple-shot injection molding of materials of which said frame and said strip are formed, in which said elastomer is a thermoplastic elastomer compatible with said thermoplastic polymer, so as to obtain said module formed as a single piece and devoid of adhesive between said strip and said frame and wherein said frame has a longitudinal hollow giving to said frame a hollow structure over an entire length of said frame.
