Shaped junction portions of tubes of an articulated seat frame |
摘要 |
In the shaped junction portion, each end of the seat and back frame is deformed in order to obtain a flattened portion in a central area conveniently stiffened by thickened areas, raised edges, or protruding outer lips providing thereby for a perfect application of the shaped end of the tube onto a face of a flange of the articulation mechanism, these parts being thereafter connected together, junction studs of each flange of the articulation inclination being used for a respective centering of the part.
