A door hinge comprises a first hinge element fastenable to a door frame and a second hinge element fastenable to a door leaf and includes first and second hinge blade. A first pivot axis is connected, when the door hinge is in a first operating condition, to first and second hinge elements such that the second hinge blade is pivotable relative to the first hinge element, in a first pivot direction, for unblocking a door aperture. The first pivot axis is decoupled from the first or the second hinge element when the door hinge is in a second operating condition. A second pivot axis is connected to the first and second hinge elements such that said first and second hinge elements are pivotable relative to one another, in a second pivot direction which is opposed to the first pivot direction, for unblocking the door aperture.
