A roof arrangement is particularly useful in a passenger car with a sliding cover which is provided for closing or partially exposing a roof opening and is linked to a lateral guiding device. The roof arrangement also has an element which can be moved with the cover and has a connection line as well as a line guiding device for the connection line. In order to be able to lay the connection line for the element in a simple manner, a screen which can be moved with the cover and which at least partially covers the lateral guiding device is provided. The connection line is guided on the screen.

Roof arrangement for a vehicle, particularly a motor vehicle

A fuel tank for vehicles, particularly passenger cars, has a filler neck which, in the area of a connection to the fuel tank, is guided around the upper edge of an adjoining body part or chassis part and penetrates a lateral fuel tank wall, a partial area of the filler neck projecting into the fuel tank interior. So that the maximal filling level of the fuel tank can be lowered under the plane A--A of the adjoining body part or chassis part, and therefore a sufficient expansion volume is ensured, it is provided that the end of the filler neck which projects into the tank interior and a filling ventilation extend below the level A--A defined by the upper edge of the body part or the chassis part, the maximal filling level H being determinable by the highest point of the filling ventilation situated in the tank interior.

Fuel tank for vehicles, particularly passenger cars

A fuel tank for vehicles, particularly motor vehicles, is provided with an operational ventilating system which is composed essentially of a vent outlet arranged in the area of an upper fuel tank wall, of an exterior air feeding and air removing pipe connected to the vent outlet, and of an activated-carbon filter connected behind. To prevent liquid fuel particles from entering the activated-carbon filter by way of the vent outlet, particularly during lateral accelerations, a device is disposed inside the fuel tank in front of the vent outlet, which device partitions off the vent outlet with respect to a direct action of liquid fuel particles.
