A method for assembling interior vehicle trim parts including panels and components in which two trim parts are disposed adjacent one another and in which a bead (12) of buffer material is disposed between mating surfaces of the two trim parts. The bead (12) is included to reduce noises such as buzzes, squeaks and rattles produced by contact and relative motion between the first and second trim parts at their mating surfaces. The bead (12) is mechanically locked into a recess in one of the mating surfaces. The bead (12) is mechanically locked to a mating surface (16) by forming a recess (24) in the mating surface (16) then applying buffer material in the recess (24). The buffer material is applied in such a way as to form a bead (12) of buffer material on the mating surface (16). The bead (12) is allowed to mechanically connect to the first trim part (16) as a result of the hardening of the buffer material within the recess (24).

L'invention concerne un procédé d'assemblage de pièces de garniture intérieure pour véhicule, notamment des panneaux et des constituants, dans lequel deux pièces de garniture sont disposées adjacentes l'une à l'autre et un bourrelet (12) de matériau tampon est disposé entre des surface d'appariement des deux pièces de garniture. Le bourrelet (12) est prévu pour réduire les bruits tels que les bourdonnements, les bruits insolites et les cliquetis produits par le contact et le mouvement relatif entre les première et seconde pièces de garniture au niveau de leurs surfaces d'appariement. Le bourrelet (12) est bloqué mécaniquement dans un évidement d'une des surfaces d'appariement. Le bourrelet (12) est bloqué mécaniquement dans une surface d'appariement (16) par formation d'un évidement (24) dans la surface d'appariement (16) puis application du matériau tampon dans l'évidement (24). Le matériau tampon est appliqué de manière à former un bourrelet (12) de matériau tampon sur la surface d'appariement (16). Le bourrelet (12) se fixe mécaniquement à la première pièce de garniture (16) du fait du durcissement dudit matériau tampon à l'intérieur de l'évidement (24).
