The hardtop consists of a metal element which is stored in the rear area of ​​the vehicle when the roof is open. [0003] With regard to acoustic comfort, there is a difference between a fabric roof and a metal folding roof. The shape of the taut fabric roof is determined by the roof bars, since the support structure becomes evident in the taut outer skin, which cannot be completely avoided and mostly does not correspond to a flow-friendly shape, whereas in the case of a coupe Many degrees of freedom are then achieved with regard to the shaping of the sheet ...
