ABSTRACT:
A vehicle seat hinge assembly having first and second generally opposed and parallel hinge plates rigidly connected in spaced relation to one another, and a central third hinge plate partially sandwiched between the first and second hinge plates is disclosed, together with a process for assembling the hinge assembly. The third hinge plate is connected in hinged relation to the first and second hinge plates by a pivot pin, which pin has a longitudinal axis and first and second shoulder portions extending in opposite axial directions from a centrally disposed annular hub portion, which shoulder portions each contain an amount of plastically deformable shoulder material. The shoulder material is plastically deformed during assembly into keyway slots formed in mounting openings provided in each of the first and second hinge plates, so that the deformed material prevents rotation of the pivot pin relative to the first and second hinge plates, so that the pivot pin is rotationally and axially fixed relative to the first and second hinge plates without the need for supplementary clips or other attachment mechanisms.
