Patented in the German Empire on December 6, 1933

The invention relates to a ventilation device for motor vehicles in which a row of thin-walled ventilation elements at an angle to the direction of travel 5 upper window frame side is arranged for sucking off the air.

It is known to have ventilation devices in vertically movable sliding windows of motor vehicles with pocket-shaped ventilation elements inclined at an angle to the direction of travel to use. These are usually arranged on the upper part of the window frame and take up the entire width of the window a.

For fastening the ventilation elements made of thin-walled building material -will special holding frames of various types are used, which are in the upper window part] are used.

ao With the known versions it is it is not possible to set up the ventilators to be common to the many different Profiles of the motor vehicle window frames can be used. Rather, the known ventilation devices only for window frames with a straight upper window edge without 'Schwiei-i' use skills. The newer motor vehicles often have windows, the upper edge of the frame is curved in the most varied of curvatures. You could do this with frame ventilators only use if one for each of the occurring window profiles would make a special associated breather frame. 'There are also ventilation systems known in which several individual ventilation members are arranged.

The novelty of the invention consists in the fact that the individual, not in context ventilation elements standing with one another, one each engaging in the upper window guide groove, have adhesive tape running in the longitudinal direction of the ventilation members. Since the individual ventilation elements are only slightly Length, it does not matter whether and how the window frame part is curved.

In the drawing, the subject matter of the invention is illustrated, namely shows:

Fig. Ι a diagrammatic representation of an upper window frame part with the glued Ventilation elements,

Fig. 2 shows a cross section through the frame with the ventilation members and

Fig. 3 and 4 are two mutually perpendicular views of the individual ventilation elements.

On the upper window frame α (Fig. 1 and 2) the individual ventilation elements b are attached to one another in a row by means of the adhesive strips c. The adhesive edges c of the ventilation members consisting of small, very thin-walled pressed pieces grip in the example shown in the upper window guide groove d of the sliding window, but can also be attached to another point of the upper window frame part. Since the weight and the

measurement of a single ventilation element is small, is sufficient, as tests have shown, fixing by gluing with a suitable adhesive means all practical needs.

The individual pressed pieces b form pockets with an inclined back surface e (Fig. 3 and 4) and an upper and lower side surface / and g. A narrow adhesive edge c is attached to the upper side surface. The pockets are designed in such a way that in their consecutive row, which is not interrupted by any holding parts or other components, they cause a strong suction effect of the passing wind. As a result, you get by with a very small height of the ventilation members, and the very inconspicuously designed ventilation device neither restricts the view through the window nor impaired the appearance of the vehicle in any way.

The ventilation elements can be made of thin-walled light metal or transparent Building material are manufactured.

The window can be closed completely by pressing the upper edge of the window Λ against the Push the pocket openings past until it reaches the upper guide groove ^.

The top corners a! of the window frame a can "be covered by special, easily cut cover sheets /, which adjoin the two end pieces of the ventilation elements b and thus form a windproof closure at rounded corners with a small radius of curvature. The cover sheets / can be glued into the corners of the window frame.
