Abstract

An inflatable roof for a passenger car extends in the inflated condition between a windshield frame and a rear area of the vehicle body and is divided into a plurality of air chambers. So that, while the drag coefficient is acceptable, a sufficient stiffness of the roof is achieved and, furthermore, any balloon-like swelling-up of the roof during the inflating of the air chambers is avoided, it is provided that the roof has air chambers with different pressure levels (operating pressure).
