Summary of the Invention

[0003] The object of the present invention is to provide an air guiding element for improving rear window ventilation.

[0004] The above object is achieved by the air guiding element and the motor vehicle as described in the following embodiments. The following embodiments also point out advantageous improvements of the present invention.

[0005] The air guiding element according to the present invention is designed to be arranged in an interior passenger compartment of a motor vehicle, which interior passenger compartment is at least partially surrounded by a window. According to the present invention, the air guiding element is further designed to generate turbulence downstream of the air guiding element when an air flow impinges on the air guiding element.

[0006] Therefore, a device is provided which can be integrated into a motor vehicle and helps to defog more quickly the window to which the air guiding element is assigned.

[0007] In an advantageous embodiment of the air guiding element according to the present invention, the latter comprises an incident flow region for receiving an air flow and an outflow region for releasing turbulence. The outflow region is in particular concave.

[0008] Thus, turbulence can be generated particularly effectively.

[0009] In another advantageous embodiment of the air guiding element according to the present invention, the air guiding element is at least partially transparent, especially translucent.

[0010] Therefore, a line of sight through the above air guiding element is ensured and the field of view is not restricted. In a transparent or translucent design, the air guiding element can in some cases be designed larger and thus more effective without obstructing the line of sight.

[0011] In another advantageous embodiment of the air guiding element according to the invention, the latter has a contact surface which is designed to be attached to the window and is in particular equipped with an adhesive layer.

[0012] Thus, the air guiding element adapts well to the rear window and can be easily installed.

[0013] In another advantageous embodiment of the air guiding element according to the invention, the latter has a lamp. The lamp is in particular formed as a brake lamp.

[0014] Thus, the air guiding element has an additional function, whereby an additional lamp can be omitted. Furthermore, in this way, greater design freedom is provided for the design and arrangement of the air guiding element.

[0015] A motor vehicle according to the invention having an interior passenger compartment at least partially surrounded by a window, comprises at least one air guiding element assigned to the rear window, which at least one air guiding element belongs to one of the above-described design variants.

[0016] By means of the air guiding element, the rear window can be defogged more quickly and thus the visibility through the window can be improved. The rapid defogging or thawing of the window provides higher safety and comfort for the passengers.

[0017] In particular, the rear window remains fogged for the longest time in a conventional motor vehicle. Therefore, the beneficial effect of the air guiding element is maximized at the rear window.

[0018] In another advantageous embodiment of the motor vehicle according to the invention, the air guiding element is arranged on the surface of the rear window facing the interior passenger compartment.

[0019] This arrangement is particularly advantageous for retrofit solutions, since the air guiding element can be easily attached to the window.

[0020] In another advantageous embodiment of the motor vehicle according to the invention, the air guiding element does not contact the window.

[0021] Thus, the air guiding element can be arranged in the interior passenger compartment in an unobtrusive and more aesthetically pleasing manner compared to the case of the adhesive variant.

[0022] In another advantageous embodiment of the motor vehicle according to the invention, the rear window has heating wires.

[0023] Thus, the effect of the air guiding element is further assisted.

[0024] In another advantageous embodiment of the motor vehicle according to the invention, it comprises at least one ventilation opening which is arranged in the interior passenger compartment and is designed to generate an air flow in the direction of at least one air guiding element.

[0025] Thus, the impact of the air flow on the air guiding element can be achieved in a more targeted manner.

[0026] In another advantageous embodiment of the motor vehicle according to the invention, the motor vehicle is a sedan.

[0027] In particular, the rear window of a sedan is affected by the problem of fogging. The provision of at least one air guiding element can solve this problem. BRIEF DESCRIPTION OF THE DRAWINGS
