Abstract
A spring assist raising assembly includes a pivot pin with a noncircular cross section which is mounted to either a pivoted panel, such as a tailgate, or a stationary member, such as a vehicle body adjacent the tailgate. A spring-loaded rotatable socket is rotatably mounted to the other of the panel or member section and is keyed to receive the pivot pin and rotate with the rotation of the tailgate by such interconnection. The socket is coupled to a spiral torsion spring, in one embodiment of the invention, such that, as the panel or tailgate is lowered, the spiral torsion spring is loaded to provide a restorative force for assisting in the raising of the panel or tailgate.
