Abstract
A method and apparatus for coupling a liftgate panel on a vehicle body for pivotal movement along a path between open and closed positions. A mounting includes hinge sets formed from two hinge leafs, at least one torsion rod extending through aligned pivot portions on each hinge set. Preferably, each hinge set is integrally formed with a common torsion pin by retainers holding ends of the torsion pin with respect to one leaf of each of the hinge sets. In a preferred embodiment, a return bent end of a common torsion pin is received in a first leaf of one of at least two hinge sets, while the other end of the rod is return bend and retained in a second leaf catch that receives an arm throughout a limited portion of the liftgate path between closed and open positions.
Claims5
A method for assembling a vehicle body liftgate panel with a hinge having at least first and second hinge sets, each hinge set having a first leaf with a first pivot portion and a second leaf with a second pivot portion comprising:
- aligning said first and second pivot portions along a common axis;
- inserting a torsion rod into said aligned first and second pivot portions of at least one of said first and second hinge sets;
- bending a first end of said torsion rod to a return bent position;
- engaging said first end into fixed engagement with one of said leafs of one of said first and second hinge leafs;
- and
- return bending the other end of said rod for retaining a second end of said torsion rod with respect to the other leaf of one of said first and second hinge sets to engage a catch through a limited portion of said path between said open and closed positions.
