  • Patent number: 8608221
    Abstract: A counterbalanced hinge system rotatably attaches a closure panel to a body for rotation about a rotation axis. The counterbalanced hinge system applies an assist torque to the closure panel to bias the closure panel about the rotation axis from a closed position into an open position. A pop-up system is moveable from an un-sprung position into a sprung position to apply an opening force to the closure panel. A reset system includes a connecting cable interconnecting the counterbalanced hinge system and the pop-up system. The reset system converts a portion of the assist torque applied by the counterbalanced hinge system into linear motion of the connecting cable to move the pop-up system from the sprung position into the un-sprung position automatically upon the closure panel moving from the closed position into the open position.
