Abstract

La présente invention concerne un support de système pour des groupes d'instruments à inclure dans des véhicules. La technologie de l'invention pour un groupe d'instruments comprend un support de système (1) avec un élément structural rigide (2) et un élément déformable (4), adjacent à un module d'informations, une unité électronique/UC (6) et des protections (7). La présente invention concerne un support de système avec lequel, dans des situations de collision de véhicule, l'élément structurel rigide se rompt et l'élément déformable subit un changement de configuration permettant le mouvement de descente de la colonne de direction. En plus de la sécurité des occupants, la présente technologie peut également fournir un protecteur d'interférences électromagnétique, réduisant ainsi l'épaisseur globale des parties du groupe d'instruments. La technologie de l'invention permet d'obtenir un modèle très mince du groupe d'instruments et offre une sécurité supplémentaire au conducteur et aux autres occupants du véhicule.
