DETAILED DESCRPTION OF THE INVENTION

[0032] FIG. 2 illustrates a perspective view of a ventilation device 11 which is attachable for example at an end of a ventilation channel for a ventilation or heating system at an instrument panel element of a motor vehicle. A ventilation device 11 of this type can also be used for other ventilation or heating systems.

[0033] The ventilation device 11 includes a housing 12 which includes at least one face frame 14 oriented towards a visible side and there behind a box or tube shaped housing section 15, as evident from FIG. 2. The frame 14 is advantageously mountable to the housing section 15.

[0034] This tube or box shaped housing section 15 is usable in a ventilation channel of the ventilation or heating system that is not illustrated in more detail. The ventilation device 11 is loaded with an air flow in a direction towards a back side of the ventilation device 11 according to FIG. 2 which provides an outflow direction from a front side of the ventilation device 11 according to FIG. 1.

[0035] In the embodiment the face frame 14 is also configured as a blind or an esthetic design element which can have many shapes.

[0036] In an outflow field 17 formed by the tubular housing section 15 a plurality of horizontal louvers 18 and vertical louvers 19 is arranged. The horizontal louvers 18 and vertical louvers 19 are advantageously oriented perpendicular to each other. The horizontal louvers 18 and the vertical louvers 19 are arranged on top of each other or nested into each other. This creates intersection points 21 between the horizontal louvers 18 and the vertical louvers 19. Advantageously these intersection points 21 are arranged in one plane.

[0037] A regulation device 23 is provided for controlling the horizontal louvers 18 and the vertical louvers 19 wherein the regulation device includes for example a single actuation element 24 which can be arranged at the visible side of the ventilation device.

[0038] This single actuation element 24 is connected with a coupling transmission 26 which actuates a push rod 27. The push rod 27 is for example oriented horizontally and engages for example each vertical louver 19. Furthermore the coupling transmission 26 is connected with a link arrangement 28 which is linked to the horizontal louvers 18 so that these are controlled to pivot about the horizontal pivot axis 32.

[0039] The actuation element 24 is for example integrated into the face frame 14. Alternatively the actuation element 24 can also be arranged outside of the face frame 14.

[0040] The regulation device 23 facilitates that the horizontal louvers 18 and the vertical louvers 19 are respectively controllable independently from each other. Thus a simultaneous pivot movement of the horizontal louver 18 and the vertical louver 19 is controllable.

[0041] FIG. 3 illustrates an exemplary perspective view of the horizontal louvers 18, The horizontal louver 18 includes a bearing pinion 31 at a face end of the horizontal louver so that the horizontal louver 18 is supported about a pivot axis 32 extending through the bearing pin 31. The horizontal louvers 18 furthermore includes groove shaped recesses 33 penetrating the pivot axis 32 wherein the groove shaped recesses 33 form a portion of a bearing 44 with the vertical louver 19. Between the groove shaped recesses 33 a protrusion 36 can be formed in the flow out direction. The geometry and shape of these protrusions 36 can be adapted to the optics in order to form an attractive and/or homogeneous visual appearance in the outflow field 17. A guide surface 37 is configured adjacent to the groove shaped recesses 33 and opposite to the outflow direction wherein the guide surface advantageously extends continuously over the length of the horizontal louvers 18. Thus, a deflection of the air flow in upward or downward direction can be provided.

[0042] FIG. 4 illustrates a perspective view of the vertical louver 19. The vertical louver 19 also includes a bearing pinion 31 at a respective face end. Thus, the vertical louver 19 is arranged to be pivot able about a pivot axis 38 in the housing 12. The vertical louver 19 includes angle shaped or triangular guide surfaces 39 so that V-shaped recesses 41 are provided between the serially arranged pennant shaped guide surfaces 39. These recesses 41 form a free space for pivot ability of the horizontal louver 18 as evident from FIG. 6. Axle sections 42 are formed between the pennant shaped guide surfaces 39. A face of the pennant shaped guide surfaces 39 that is pointed in the outflow direction can be adapted with respect to geometry and shape to a desired visual appearance of the flow out field 17.

[0043] FIG. 5 illustrates a schematic view where the horizontal louvers 18 and the vertical louvers 19 are placed into each other. Thus, the groove shaped recesses 33 of the horizontal louver 18 receive the axle sections 42 of the vertical louver 19 and form a bearing 44 in the intersection point 21 wherein the bearing associates and fixates the horizontal louver 18 and the vertical louver 19 relative to each other, wherein a pivot ability of the horizontal louver 18 about the pivot axis 32 and of the vertical louver 19 about the pivot axis 38 is maintained, The pivot axes 32 of the horizontal louvers 18 and the pivot axes 38 of and the vertical louvers 19 intersect wherein the intersection points 21 are advantageously all arranged in a common plane.

[0044] Through this nesting of the horizontal louver 18 and the vertical louver 19 it is evident according to FIG. 5 that the vertical louver 19 is pivotable about the pivot axis 38 regardless of an orientation of the horizontal louver 18.

[0045] FIG. 6 shows a side view of FIG. 5. This emphasizes that the pivotability of the horizontal louver 18 is facilitated by the shaped recess 41 or through the pennant shaped configuration of the guide surface 39 of the vertical louver 19. The bearing 44 formed in the intersection point 21 thus facilitates a pivot movement of the vertical louver 19 about its pivot axis 38 as well as a pivot movement of the horizontal louver 18 about its pivot axis 32.

[0046] The face frame 14 and the tubular housing section 15 can include bearing receivers 46 at respective faces that are oriented towards each other so that a simple assembly is provided after positioning the horizontal louvers 18 on the housing section 15 and subsequent arrangement of the vertical louvers 19 by fixating the frame 14 relative to the housing section 15.

[0047] FIG. 7 illustrates a schematic front view of the ventilation device 11 according to FIG. 1. Thus, the homogenous visual appearance of the horizontal louvers 18 and the vertical louvers 19 becomes apparent.
