A structurally enhanced attachment (10) for use in reinforcing automotive assemblies. An expandable material (16), is disposed on a surface of an extrusion (12) with closed sections (14) prior to integration of the extrusion (12) into the vehicle and final assembly of the vehicle by the vehicle manufacturer. The system is activated as the vehicle undergoes the final vehicle assembly process, which activates and transforms the expandable material (16), preferably during an automobile paint operation, to expand, bond and fill the rocker assembly structure thereby securing the extrusion (12) with the rocker assembly and facilitating enhanced structural reinforcement.

L'invention concerne une fixation (10) structurellement renforcée pour le renforcement d'ensembles automobiles. Une matière (16) expansible est placée sur une surface de pièce d'extrusion (12) comportant des parties (14) fermées, avant intégration de la pièce d'extrusion (12) au véhicule et montage final de celui-ci par le constructeur de véhicules. Le système est activé lorsque le véhicule est soumis au procédé final de montage du véhicule : la matière (16) expansible est activée et transformée, de préférence pendant une opération de peinture de l'automobile, de manière à s'étendre, à lier et à remplir la structure de l'ensemble bas de caisse, ce qui permet de fixer la pièce d'extrusion (12) à l'ensemble bas de caisse et d'obtenir un renfort structural amélioré.
