The invention relates to a motor vehicle having a panel or door, which can be brought from a closed position into an open position against the force of gravity using at least one energy storage element and means coupled therewith for influencing the torsional moment provided on the panel or door by the at least one energy storage element, wherein the panel or door is rotatably supported about an axis of rotation, and wherein the torsional moment can be influenced by the means for influencing depending on the opening position of the panel or door.

Motor vehicle having a mechanism for moving a panel or door

A method for installing a spring-assisted liftgate in opposition to the gravity force includes temporarily fixing a coupling rod in a defined position corresponding to an installation position of the liftgate, and holding the in an open position or in an intermediate position above the installation position and placing the apparatus in the vehicle. After lowering the liftgate from the open position or intermediate position into the installation position, the coupling rod is connected to the hinge lever and then released.

Method for the installation of an apparatus for spring-assisted swinging of a liftgate or door in a vehicle

An apparatus for spring-assisted pivoting a liftgate or door against gravity between a closed position and an open position includes a torsion bar spring system with springs arranged in parallel in a meander pattern and connected with one another in fixed rotative engagement. An outer bearing-torsion bar spring and another outer lever-torsion bar spring are each supported in a support bracket of a tracker. The lever-torsion bar spring is connected in fixed rotative engagement with a length-adjustable lever guided in a control cam of the tracker. A coupling rod configured for translatory movement engages with the length-adjustable lever for rotating a hinged lever associated with the liftgate or door. An adjusting device is connected with the bearing-torsion bar spring in fixed rotative engagement and can be variably locked relative to the support bracket. A method for producing such apparatus is also disclosed.
