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).

Abstract: A bumper arrangement for motor vehicles consists of a deformation-resistant support, which extends transversely with respect to the longitudinal direction of the vehicle and is supported with respect to the vehicle. A covering covers the support and has an edge portion with a deformation-resistant strip which is fastened at an adjacent body portion of the motor vehicle. The covering can be adjusted with respect to the adjacent body portion to be flush with the shell of the body portion by locally arranged clamping elements braced against a recess-shaped area of the body. The clamping elements are prepositioned and held at the body by screwable fastening members which interact with spreading members and which are operated from an interior space of the vehicle.
