  • Patent number: 7870643
    Abstract: The invention relates to a hinge arrangement, in particular for a tailgate of a motor vehicle, having a first hinge part, in particular firmly connected to the body, which is knuckle-jointed with a second hinge part, and having an energy accumulator, the force application points of which are positioned in relation to both hinge parts in such a way that the force released upon its discharge supports the rotation of the two hinge parts around the hinge axis from a first rotation position, which corresponds in particular to a closed position of the tailgate, to a second rotation position, which corresponds in particular to the open position of the tailgate. To obtain useful improvements, a transposition device is proposed for transposing at least one force application point in one of the two rotation positions, so that after a transposition onto the hinge parts a force acts in the opposite rotation direction.
