       3 . A device according to  claim 1 , wherein:
 the first wall comprises longitudinally oriented fibers, the fibers being embedded in a resin.   
   
   
       4 . A device according to  claim 1 , wherein:
 the first and second walls are removably affixed together.   
   
   
       5 . A device according to  claim 1 , wherein:
 the first and second walls are non-removably affixed together.   
   
   
       6 . A device according to  claim 1 , wherein:
 the second wall has a peripheral groove defined on a front surface to receive the first wall.   
   
   
       7 . A device according to  claim 1 , wherein:
 the second wall has ribs projecting with respect to the front surface;   screws are threaded in the ribs through the first wall.   
   
   
       8 . A device according to  claim 1 , wherein:
 the rear support element has an inner cavity between the first and second walls.   
   
   
       9 . A device according to  claim 8 , wherein:
 the inner cavity receives, at least in part, a mechanism to adjust an angular position of the rear support element.   
   
   
       10 . A device according to  claim 1 , wherein:
 the first and second walls of the rear support element are flatly pressed against one another.   
   
   
       11 . A device according to  claim 6 , wherein:
 the peripheral groove is set back with respect to the ends and to the edges;   the contour of the first wall being positioned In the groove of the second wall.   
   
   
       12 . A device according to  claim 1 , wherein:
 the first and second walls are affixed by ratchet.   
   
   
       13 . A device according to  claim 1  further comprising:
