         5 . The rear floor arrangement according to  claim 1 , wherein the first supporting structure component has a downwardly open cross-sectional profile at least in the certain area that in an installed position on the motor vehicle is closed at least in the certain area by the floor. 
     
     
         6 . The rear floor arrangement according to  claim 1 , wherein the first supporting structure component has a downwardly open cross-sectional profile at least in the certain area that in an installed position on the motor vehicle is closed at least in the certain area by a floor rear. 
     
     
         7 . The rear floor arrangement according to  claim 1 , wherein the first supporting structure component has a downwardly open cross-sectional profile at least in the certain area that in an installed position on the motor vehicle is closed at least in the certain area by the second supporting structure component. 
     
     
         8 . The rear floor arrangement according to  claim 1 , wherein at least two first supporting structure components that are spaced apart from one another in the vehicle transverse direction are connected to one another with at least one transverse member. 
     
     
         9 . The rear floor arrangement according to  claim 1 , wherein the first supporting structure component is configured as a high-strength steel sheet. 
     
     
         10 . The rear floor arrangement according to  claim 1 , wherein the first supporting structure component is configured as a cast component fabricated from a light metal. 
     
     
         11 . The rear floor arrangement according to  claim 1 , wherein the first supporting structure component is configured to be free from corrosion protection. 
     
     
         12 . A frame structure of an under floor arrangement of a self-supporting body of a motor vehicle, comprising:
 at least one first supporting structure component disposed in a region of a rear floor; and   at least one second supporting structure component disposed in the region of a floor middle,   wherein first and second supporting structure components are connected to one another at least in certain areas lying in the region of the motor vehicle.   
     
     
         13 . The frame structure according to  claim 12 , wherein the at least one first supporting structure component is configured as part of a rear frame and at least one second supporting structure component is configured as a longitudinal member. 
     
     
         14 . The frame structure according to  claim 12 , wherein the at least one first supporting structure component and at least one second supporting structure component are disposed entirely in the region of the motor vehicle. 
     
     
         15 . The frame structure according to  claim 12 , wherein at least the at least one first supporting structure component or the at least one second supporting structure component have a downwardly open cross-sectional profile at least in a certain area that in an installed position on the motor vehicle is closed at least in the certain area by a corresponding floor section. 
     
     
         16 . The frame structure according to  claim 12 , wherein the at least one first supporting structure component is supported on the at least one second supporting structure component in a transition region to the at least one second supporting structure component forming a vertical offset. 
     
     
         17 . The frame structure according to  claim 12 , wherein the at least one first supporting structure component or the at least one second supporting structure component are configured as a high-strength steel sheet. 
     
     
         18 . The frame structure according to  claims 12 , wherein the at least one first supporting structure component or the at least one second supporting structure component are configured as a cast component fabricated from a light metal. 
     
     
         19 . The frame structure according to  claim 12 , wherein the at least one first supporting structure component or the at least one second supporting structure component are configured to be free from corrosion protection
