Joe;
 Ron or Del could give you a better technical definition of these things but 
their function is kinda simple so I'll try :-)
 "counter bearing bar" might not be the proper terminology but that is what I 
have always called them.  ON S&S these bars are cast in the plate with three 
sections each in treble and middle tenor...in the tenor section this function 
is performed by that wide, curved, piece of felt/oilpaper that lies between 
the tuning pins and the agraffes. Some instruments use "half-round" steel or 
brass bars which are not cast into the plate.
 For all of these things the purpose is to provide a smooth rendering surface 
for the strings while providing (slightly adjustable in some cases) "up" 
pressure directly 'behind' the capo or agraffe.  
  This, in theory I suppose, provides for a more positive speaking length 
termination at the capo or agraffe.
