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).
Claims22
An inflatable roof for a vehicle, which extends in an inflated condition between a windshield frame and a rear area of the vehicle body, the roof being divided into a plurality of air chambers, wherein the roof has air chambers with different operating pressure levels, all of said different operating pressure levels being greater than an atmospheric pressure level.
