The luggage item according to  claim 12 , further comprising a modifiable ceiling between the reduced position and said at least one extended position, the modifiable ceiling comprises a front and rear rigid parts connected together, the front and rear rigid parts of the modifiable ceiling are complementary or connected with fittings to ensure an overall rigidity of the modifiable ceiling in the first volume position; and the rigid front part of the modifiable ceiling is remote from the rear rigid part of the modifiable ceiling in the second volume position by a relative sliding motion on rigid sliding stems of the modifiable ceiling. 
     
     
         15 . The luggage item according to  claim 12 , wherein each of the front and rear rigid parts of the modifiable floor comprises an inner edge with a saw-toothed profile, the front and rear rigid parts are connected the rigid sliding stems. 
     
     
         16 . The luggage item according to  claim 14 , wherein each of the front and rear rigid parts of the modifiable ceiling comprises an inner edge with a saw-toothed profile, the two rigid parts are connected by rigid sliding stems. 
     
     
         17 . The luggage item according to  claim 12 , wherein the rigid stiffener comprises rigid closed frames and swiveling frames. 
     
     
         18 . The luggage according to  claim 17 , wherein the swiveling frames present a C shape conformation; and further comprising struts configured to close the C shape conformation to prevent a distortion of the luggage item. 
     
     
         19 . The luggage item according to  claim 12 , wherein the rigid stiffener comprises a lock to secure the luggage item in a position corresponding to a selected volume. 
     
     
         20 . The luggage item according to  claim 18 , wherein an end of the swiveling frames of the C shape conformation are guided, during a sliding motion, on rails laid out on a front face side of the luggage item to provide an access to contents of the luggage item. 
     
     
         21 . The luggage item according to  claim 17 , wherein the swiveling frames form a V in the first volume position of the luggage item and stands parallel in the second volume position of the luggage item. 
     
     
         22 . The luggage according to  claim 12 , further comprising a shifting element to shift from the first volume position of the luggage item to the second volume position of the luggage item, and conversely.
