Profile section molded by multi-injection molding and forming a seal or a molding for the body of a motor vehicle, and method for manufacturing same

Abstract

The present invention relates to a profile section molded by the multi-injection molding of thermoplastic materials having different hardnesses, and forming a seal or a molding for the body of a motor vehicle, as well as to a method for manufacturing said profile section. Said profile section (″) includes at least: an antifriction coating (″) tightly bonded to a longitudinal sealing surface (″) of the profile section and intended enabling the latter to sealingly contact a mobile element of the vehicle, said sealing surface ending, substantially at a right angle at the respective ends thereof, in two transverse sealing edge surfaces of the profile section; and/or a decorative film (″) tightly bonded to a visible longitudinal surface (″) of the profile section and intended for enhancing the appearance of said surface, wherein said visible longitudinal surface is separate from the sealing surface and ends, substantially at a right angle at the respective ends thereof, in two visible transverse edge surfaces of the profile section, characterized in that said materials are overmolded: (i) either on said coating(s) or on said film(s), which is/are tightly bonded, in a continuous manner, to at least one of the visible edge surfaces; (ii) or on said coating(s) and on said film(s), which are optionally tightly bonded, in a continuous manner, to at least one of the sealing edge surfaces and to at least one of the visible edge surfaces.
