[GRASSLIST:472] Last Step on creating axis between 2 lines...

Hi guys!
Using a buffer very big, one very small and then v.overlay, I reached this
result trying to found the axis between 2 lines:

The last step (then r.thin,r.to.vect and v.clean it's not a problem...) is to
extract just the area inside the 2 lines, but i don't know how to do it...
Both the one inside and the one outside are from same layer (very big buffer)
Any Idea?

Thx
Luca
