         8 . The vacuum-cleaner filter bag according to  claim 7 , wherein the bag wall is welded to the third plate, and wherein the third plate comprises a plastic which is compatible with a plastic material of an outermost layer of the bag wall to which the third plate is welded. 
     
     
         9 . A system, the system comprising:
 a vacuum-cleaner filter bag, the vacuum-cleaner filter bag comprising:
 a bag wall and a retaining plate connected thereto; and 
 wherein the retaining plate comprises a first plate and a second plate arranged in a first plane, and a third plate arranged in a second plane which runs in parallel to the first plane, the third plate having a lower flexural stiffness than the first plate and the second plate, and wherein the first plate and the second plate are interconnected by means of the third plate such that a hinge is formed between the first plate and the second plate about a hinge axis (A) of which the first plate and/or the second plate can be bent together with a respective part of the third plate connected thereto; and 
   a mounting for the retaining plate in a vacuum-cleaner housing, wherein the mounting is designed such that the first plate and/or the second plate and the respective part of the third plate connected thereto are bent about the hinge axis (A) in an operating position with respect to the first and second planes.   
     
     
         10 . The retaining plate according to  claim 2 , wherein the third plate is made of a material different from that of the first plate and/or the second plate, and wherein the material of the third plate has a lower elastic modulus than the material of the first plate and/or the second plate. 
     
     
         11 . The retaining plate according to  claim 10 , wherein the first plate and the second plate are glued, welded, or positively connected to the third plate. 
     
     
         12 . The vacuum-cleaner filter bag according to  claim 8 , wherein the third plate is designed to be thinner than the first plate and/or the second plate.
