       14 . The vehicle seat according to  claim 13 , wherein: 
 the backrest is mounted for being rotated about 
 (a) a first axis relative to the seat cushion support, and  
 (b) a second axis relative to vehicle structure,  
   the seat cushion support is connected to the vehicle structure via pivotable links, and    pivots of the pivotable links in combination with the first and second axes define on each side of the vehicle seat a quadruple-joint through which the vehicle seat can be converted from a use position, in which the backrest extends uprightly from the seat cushion support, to a compacted configuration by folding the backrest forwardly and the lowering of the seat cushion support.    
   
   
       15 . A vehicle seat comprising:
