Method of manufacturing by electron or laser beam welding of a back and/or seat structure

摘要

Production of composite structures made up of a flat component (2) and a profile (3) comprise welding the ends (5) of the arms (4) of the profile to the front surface of the flat component by applying a laser- or electron beam (8) to the rear side (7) of the component. An independent claim is included for backrests and seats for vehicles incorporating composite structures produced as described.
