Linkage assembly with extruded hole member

摘要

A linkage assembly for use with kinetic mechanisms such as an automotive seat assembly having an elongated torsion rod made of either a solid bar or a hollow cylindrical tube, and at least one linkage member having an aperture corresponding to the cross-sectional profile of the torsion rod and adapted to receive the torsion rod therethrough. The linkage member includes an essentially flat sheet of metal extending from and coplanar to the aperture and an outwardly extending extruded metal flange which projects upward from the flat surface of the linkage member. The extruded flange defines a sleeve through which the torsion member extends. A weld seam is located at the terminal end of the flange in attaching contact between the torsion rod and the flange to form a secure union between the two members.
