ABSTRACT:
A relatively uncomplicated hinge and spring assembly for effectively counterbalancing the trunk lid of an automotive vehicle and for partially opening that lid when it is unlatched. The assembly utilizes an adjustable tension coil spring that exerts a diminishing lifting force as the lid is raised and that, at the manufacturer's/user's option, is used to counterbalance or slightly exceed the gradually diminishing unsupported weight of the lid as it moves from lowered to raised position. The lifting force is augmented over a limited arc of the lid's travel, by lateral deflection or distortion of the spring, to urge the lid into its partially-raised position when it is unlatched.
