Opening leaf upper module for a vehicle glass panel

摘要

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.
