Cover for a sliding roof system

Abstract

A cover for a sliding roof system includes first and second guiding elements that are mounted to opposite sides of the cover in such a manner that their mutual distance is variable, and first and second pivot arbors that are formed on the cover so as to have a fixed distance between them. The cover also includes first and second adjusting elements. The first adjusting element is coupled to the first guiding element and mounted to the cover such that the first adjusting element can be rotated about the first pivot arbor. The second adjusting element is coupled to the second guiding element and mounted to the cover such that the second adjusting element can be rotated about the second pivot arbor. A first traction member is coupled to the first and second adjusting elements on one side of the respective first and second pivot arbors, and a second traction member is coupled to the first and second adjusting elements on an opposite side of the respective first and second pivot arbors. The first and second traction members are permanently subjected to a tensile load.

1 . A cover for a sliding roof system comprising: 
 first and second guiding elements that are mounted to opposite sides of the cover such that a distance between the first and second guiding elements is variable;    first and second pivot arbors that are formed on the cover to have a fixed distance between the first and second pivot arbors;    first and second adjusting elements, with the first adjusting element being coupled to the first guiding element and mounted to the cover such that the first adjusting element can be rotated about the first pivot arbor, and the second adjusting element being coupled to the second guiding element and mounted to the cover such that the second adjusting element can be rotated about the second pivot arbor;    a first traction member that is coupled to the first and second adjusting elements on one side of the first and second pivot arbors; and    a second traction member that is coupled to the first and second adjusting elements on an opposite side of the first and second pivot arbors, the first and second traction members being subjected to a tensile load.    
   
   
       2 . The cover according to  claim 1  wherein at least one of the first and second adjusting elements is a two-armed lever.  
   
   
       3 . The cover according to  claim 2  wherein a corresponding one of the first and second guiding elements is articulated to the two-armed lever by a working lever.  
   
   
       4 . The cover according to  claim 1  wherein at least one of the first and second adjusting elements comprises a gearwheel in combination with a cable pulley.  
   
   
       5 . The cover according to  claim 4  wherein a corresponding one of the first and second guiding elements comprises a toothed rack that is coupled to the gearwheel.  
   
   
       6 . The cover according to  claim 1  wherein the first and second traction members are configured as two separate components.  
   
   
       7 . The cover according to  claim 1  wherein the first and second traction members are configured in one piece.  
   
   
       8 . The cover according to  claim 7  including a spring that keeps at least one of the first and second traction members under tensile load.  
   
   
       9 . The cover according to  claim 1  wherein at least one of the first and second traction members is a metal cable.  
   
   
       10 . The cover according to  claim 1  wherein at least one of the first and second traction members is a chain.  
   
   
       11 . The cover according to  claim 1  wherein the first traction member extends laterally between the first and second adjusting elements on one longitudinal side of the first and second pivot arbors and the second traction member extends laterally between the first and second adjusting elements on an opposite longitudinal side of the first and second pivot arbors.  
   
   
       12 . The cover according to  claim 1  wherein the first and second adjusting elements pivot relative to the cover as the cover is shifted between first and second positions, and wherein the first and second adjusting elements remain parallel to each other during pivoting movement to maintain a constant distance between the first and second adjusting elements.  
   
   
       13 . The cover according to  claim 1  wherein the first and second guiding elements are slidably received in first and second guide rails, respectively.  
   
   
       14 . The cover according to  claim 13  including a first working lever coupled to the first guiding element and the first adjusting member, and a second working lever coupled to the second guiding element and the second adjusting member.  
   
   
       15 . The cover according to  claim 14  wherein the first and second working levers are each attached to the cover with a slot and pin connection.  
   
   
       16 . The cover according to  claim 1 , wherein the first and second traction members are permanently subjected to the tensile load once the first and second traction members are coupled to the first and second adjusting elements.
