Since May 2017 a consortium of research and industry partners has been working on the project FUMAS, the official kick-off already has taken place at Dortmund on 19th September in 2017. FUMAS stands for „Lightweight magnesium design of automobile seat structures including functional integration” (in German: „Funktionsintegrierter Magnesiumleichtbau an Autositzstrukturen“). The project is planned for a term of three years from May 2017 until April 2020. It is promoted by the Federal Ministry of Economics and Energy, the project executing organisation is TÜV Rheinland Consulting GmbH.
In large-scale production of vehicle seats, high and ultra-high strength steel alloys prevail because of challenging requirements. The potentials of metal lightweight structures using steel and aluminum are exhausted to a large extent. The project aims at weight reduction of a seat structure by using extruded magnesium and a novel process route in manufacturing. A concept for a lighter seat back structure is to be developed, dimensioned and evaluated. This predevelopment process is based on numerical as well as experimental methods and is finally to be validated with generic substructures.
As an internationally operating, leading manufacturer of automobile seat structures, Faurecia Autositze GmbH coordinates the project. The SME KODA Stanz- und Biegetechnik GmbH contributes essentially in tool manufacturing and process route. From the research perspective, the Institute of Vehicle Concepts of the German Aerospace Center dimensions the seat structure considering process route and material specialties. Concerning stable thermo-mechanical forming, joining by friction stir welding and concepts preventing corrosion Helmholtz-Zentrum Geesthacht is part of the project team. In surface engineering, as a subcontractor JUBO Technologies GmbH delivers essential contributions for the success of the project.
