    Abstract: A convertible has a convertible top which can be put away in the rear region of the convertible and, in a fully open position, is received in a convertible top compartment which can be at least partially closed by a convertible top compartment cover. In this case, the put-away convertible top is held down with the aid of the convertible top compartment cover and is fixed in the held-down position by at least one holding-down device which can be placed onto the convertible top and is disposed on the convertible top compartment cover. The holding-down device has a friction-reducing coating facing the convertible top.

  • Patent number: 7762610
    Abstract: A convertible top can be displaced between a closed position and a put-away position. The convertible top contains a flexible convertible top cloth, rear side regions of which each have at least one folding device acting on them, impressing at least one defined fold in each case on the convertible top cloth during the transfer from the closed position into the put-away position. Each folding device has at least one linear, rod-shaped folding mechanism which, during the transfer of the convertible top into the put-away position, prevents a folding of the convertible top cloth transversely with respect to its longitudinal direction.
