The joint reinforcement member (30) for a hollow structure of an automobile vehicle (13) has a carrier portion (22) with an outer surface. The carrier portion has a base portion (30) with a first extension having a first longitudinal axis and a second extension having a second longitudinal axis. The first longitudinal axis and second longitudinal axis correspond to the hollow structure. A thermally expandable adhesive layer (38) is disposed on the outer surface of the carrier portion and substantially covers the outer surface. A method for forming the joint member includes providing a carrier having a plurality of extensions extending from a base portion that correspond to the hollow structure, applying a layer of thermally expandable adhesive materials applied to the carrier portion. The carrier portion is heated to activate the adhesive layer. The adhesive layer is cooled so that the adhesive is bonded to the structural member.
Cet élément d'armature d'assemblage (30), destiné à une structure creuse d'un véhicule automobile (13), présente une portion de support (22) pourvue d'une surface extérieure. Cette portion de support comprend également une portion de base (30) présentant une première extension possédant un premier axe longitudinal ainsi qu'une seconde extension possédant un second axe longitudinal. Les premier et second axes longitudinaux correspondent à la structure creuse. On a déposé une couche adhésive thermodilatable (38) sur la surface extérieure de la portion de support, qui couvre sensiblement cette surface extérieure. L'invention concerne un procédé de formation d'un élément d'assemblage comprenant les étapes consistant à préparer un support présentant plusieurs extensions s'étendant à partir d'une portion de base correspondant à la structure creuse, à appliquer une couche de matières adhésives thermodilatables sur la portion de support, à chauffer celle-ci pour activer la couche adhésive, puis à refroidir la couche adhésive de façon à la fixer sur l'élément structurel.
