       2 . The motor vehicle seat as defined in  claim 1 , wherein the supporting wings are connected either to the supporting plate in a respective pivot joint or directly to the supporting plate. 
   
   
       3 . The motor vehicle seat as defined in  claim 1 , wherein the supporting wings are configured to be elastic. 
   
   
       4 . The motor vehicle seat as defined in  claim 1 , wherein a hand or motor driven adjustment device for adjustment in the longitudinal direction is provided between the seat part and the supporting plate. 
   
   
       5 . The motor vehicle seat as defined in  claim 1 , wherein the supporting wings have a free end and that said free end fits laterally against the seat part, a slide means being provided between the free end and the seat part. 
   
   
       6 . The motor vehicle seat as defined in  claim 1 , wherein each supporting wing has a free end and that said free end substantially points backward in the longitudinal direction. 
   
   
       7 . The motor vehicle seat as defined in  claim 1 , wherein the seat part comprises left and right lateral slide surfaces or guide surfaces for abutment of the respective one of the supporting wings. 
   
   
       8 . The motor vehicle seat as defined in  claim 1 , wherein the seat part comprises two openings and that one supporting wing engages in each opening. 
   
   
       9 . The motor vehicle seat as defined in  claim 1 , wherein the seat part has a seat part width and the supporting plate has a width that is maximally about 80% of the seat part width. 
   
   
       10 . The motor vehicle seat as defined in  claim 1 , wherein the seat pan includes a padding a portion of which is located above the supporting plate and that, upon adjustment of the supporting plate in the longitudinal direction, the supporting plate moves together with its supporting wings relative to the padding. 
   
   
       11 . The motor vehicle seat as defined in  claim 9 , wherein the padding comprises a slide surface on its underside turned toward the supporting plate. 
   
   
       12 . The motor vehicle seat as defined in  claim 9 , wherein the seat pan further comprises a covering that is located outside of the padding that it covers and has an end region that is located underneath the supporting plate, wherein the end region is elastically retained and is not directly connected to the supporting plate. 
   
   
       13 . The motor vehicle seat as defined in  claim 10 , wherein the seat pan further comprises a covering that is located outside of the padding that it covers and has an end region that is located underneath the supporting plate, wherein this end region is elastically retained and is not directly connected to the supporting plate. 
   
   
       14 . The motor vehicle seat as defined in  claim 12 , wherein the end region comprises an elastic part. 
   
   
       15 . The motor vehicle seat as defined in  claim 13 , wherein the end region comprises an elastic part. 
   
   
       16 . The motor vehicle seat as defined in  claim 1 , wherein the supporting plate comprises a first insertion opening on one seat side and the seat part has a mating second plug-type projection on this seat side or the supporting plate comprises a first plug-type projection on one seat side and the seat part has a mating second insertion opening on this seat side.
