Abstract

A rear for passenger automobiles of the type having a pivotal hatch inserted in a rear opening of a vehicle body and extending in a smooth flowing line toward the rear and including a window in a transversely extending lower frame adjoining the window, is provided, in accordance with the preferred embodiment of the invention, with an aerodynamic device on the lower frame of the hatch, the aerodynamic device having sections extended laterally from the hatch along lateral body parts of the vehicle. The laterally extended sections should preferably merge into and terminate at the lateral body parts. Additionally, in hatches where frames are provided extending in the longitudinal direction of the vehicle, ribs are provided extending away from the aerodynamic device, running along the frames, and forming an aerodynamic unit with the aerodynamic device. The ribs preferably taper in height in the direction away from the aerodynamic device so as to merge into and terminate near upper ends of the longitudinally directed frames of the hatch.
