ABSTRACT:
A lift-gate dual latch mechanism utilizing both a primary spring and an auxiliary spring operates to provide the additional force needed to release a striker member from both stop positions of a dual latch. Without the auxiliary spring as mentioned above, the lift-gate, being a heavy member typically stays in the latching mechanism when the lift-gate key is actuated to the open position. This requires additional lift forces, such as added springs between the lift-gate and the back panel of the vehicle to open the lift-gate from the mandated second lock position. Gas cylinders are shown to assist the opening of the lift-gate when required.
