Vane actuating system, in particular for an air outflow

Abstract

A vane actuating system, in particular for an air outflow for vehicle air- conditioning, comprises a first vane ( 12 ) which is held in a frame ( 10 ) so as to be swiveling about a first axis (A), and a second vane ( 16 ) which is held in the frame so as to be swiveling about a second axis (B). An operating element ( 28 ) is arranged on the first vane, which element ( 28 ) is connected with the second vane ( 16 ) by means of a sliding-/cardan joint.

1 . A vane actuating system, in particular for an air outflow for vehicle air-conditioning, comprises a first vane ( 12 ) which is held in a frame ( 10 ) so as to be swiveling about a first axis (A), and a second vane ( 16 ) which is held in said frame so as to be swiveling about a second axis (B), an operating element ( 28 ) being arranged on said first vane, which element ( 28 ) is connected with said second vane ( 16 ) by means of a sliding-/cardan joint ( 32 ,  36 ,  37 ,  38 ,  42 ).  
     
     
         2 . The vane actuating system according to  claim 1 , characterized in that said operating element ( 28 ) is moveable on said first vane (l 2 ) parallel to said first axis (A).  
     
     
         3 . The vane actuating system according to  claim 1 , characterized in that said sliding-/cardan joint has a fork ( 36 ), which is connected with said first and second vanes ( 12 ,  16 ).  
     
     
         4 . The vane actuating system according to  claim 3 , characterized in that said fork ( 36 ) is fastened to said operating element by means of a cardan joint ( 37 ,  38 ) and to said second vane ( 16 ) by means of a sliding guide ( 32 ,  42 ).  
     
     
         5 . The vane actuating system according to  claim 4 , characterized in that said fork ( 36 ) has two side webs ( 40 ) which rest against outer surfaces of said second vane ( 16 ).  
     
     
         6 . The vane actuating system according to  claim 5 , characterized in that said side webs ( 40 ) have several elevations ( 37 ) by means of which they lie against said vane ( 16 ).  
     
     
         7 . The vane actuating system according to  claim 1 , characterized in that said first and second axes (A, B) are perpendicular to each other.  
     
     
         8 . The vane actuating system according to  claim 1 , characterized in that in addition to said first vane ( 12 ), further vanes ( 14 ) are provided, which are coupled with said first vane ( 12 ) such that they have the same orientation as said first vane.  
     
     
         9 . The vane actuating system according to  claim 8 , characterized in that in addition to said second vane ( 16 ), further vanes ( 18 ) are provided, which are coupled with said second vane such that they have the same orientation as said second vane.  
     
     
         10 . The vane actuating system according to  claim 9 , characterized in that said first and second vanes are provided with a bearing pin ( 22 ;  26 ), on which a coupling rod ( 20 ;  24 ) engages.  
     
     
         11 . The vane actuating system according to  claim 10 , characterized in that said further vanes are aligned parallel with said first and second vanes, respectively.
