Abstract: A ventilating system for vehicle bodies, especially of passenger motor vehicles, in which the rear column accommodates within its hollow space an air conduction and water discharge installation and which is provided with one or several air dishcarge openings within the area of the rear column; the air conduction and water discharge installation is thereby constructed trough-shaped and is formed out of a profiled partition wall that is supported at the narrow sides of the rear column and extends from the roof area to near the wheel casing; the air inlet takes place from the vehicle body behind the air discharge opening offset in the driving direction while the lower boundary of the air conduction and water discharge installation is formed by the lower edge of the lowermost air discharge opening.

Abstract: A hollow bearer for a passenger motor vehicle which extends in the vehicle transverse direction underneath the rear window, which is constructed as channel for the air exhaust and which, except for the offset connecting areas on the side of the rear columns, consists of three profiled sheet-metal members non-detachably connected with each other; the first, rear upper sheet-metal member is thereby provided with a support flange for the rear window while the second sheet-metal member which is equipped with inlet openings for the exhaust air, adjoins the support flange in the direction of a forward hat storage shelf; the first and second sheet-metal members are then completed into an air guide channel by a closure sheet-metal member disposed therebelow whereby the closure sheet-metal member forms the rear termination of a bearer sheet-metal member for the hat storage shelf.
