Method of making applique for pillar area of vehicle
View Patent ↗A pillar applique for use at a pillar area (e.g., A-pillar area) of a vehicle. The pillar applique includes a substrate portion and a thermoplastic elastomer portion. Each of the substrate portion ( 21 ) and the thermoplastic elastomer portion ( 23 ) are formed via injection molding in certain embodiments of the invention, and the thermoplastic elastomer portion may be injection molded over the substrate portion during its forming process (or vice versa) so that the two portions may be bonded to one another without the need for additional adhesive.
1. A method of making a vehicle pillar appliqué for use on a vehicle, the method comprising:
a) injection molding one of: 1) a polymer inclusive substrate, and 2) a thermoplastic elastomer portion;
b) in a subsequent injection molding step, injection molding the other of 1) said polymer inclusive substrate, and 2) said thermoplastic elastomer portion, to the one injection molded in step a), in order to form the appliqué which includes the polymer inclusive substrate and the thermoplastic elastomer portion molded to each other;
c) selecting durometer values for the thermoplastic elastomer portion and the polymer inclusive substrate, so that the polymer inclusive substrate has a higher durometer and is less flexible than the thermoplastic elastomer portion; and
d) attaching the applique formed in b) to the vehicle proximate a pillar area thereof in a manner so that the polymer inclusive substrate of the appliqué includes an interior surface to be closest to a vehicle window and an exterior surface to be further from the window than is the interior surface, and wherein at least part of the interior surface of the polymer inclusive substrate is for facing a peripheral edge of the vehicle window and the thermoplastic elastomer portion is at least bonded to at least part of an interior surface of the polymer inclusive substrate facing the peripheral edge of the vehicle window so that the at least part of the thermoplastic elastomer portion is provided between the peripheral edge of the vehicle window and the interior surface of the polymer inclusive substrate.
2. The method of claim 1 , wherein the thermoplastic elastomer portion and the substrate are molded or bonded to one another during the injection molding step b) without a separate adhesive layer therebetween.
