ROOF STRUCTURE WITH A BELLOW
A roof construction for a motor vehicle, including a displaceable roof element which is displaceable between a retracted out-of-use position and an extended use position, wherein the roof element in its extended use position is in a spaced-apart position relative to a body of the vehicle. Arranged on the roof element is a folding bellows which, when the roof element is in the use position, assumes an opened state and bridges a gap between the roof element and the body, and which, when the roof element is in the out-of-use position, assumes a compressed state collapsed in folds. The folding bellows has a layer structure with at least two different layers.
