Vibra Artiste truss rod........

Hi all.
Been fiddling around with my V.A tonight, and altough my example has a really nice low action,(although needing a refret) i thought id adjust the truss rod.
Every one ive come across are all basically the same - and all DO the same thing -(some Fenton Weill Types too,according to MGEEK)
Its just an exposed threaded bar, and two nuts on it, simple enough, but it seems to work in the opposite direction, ie normally you would presume that tightening the nuts down into the neck would straighten it out, but in all examples ive had it sort of makes it MORE bowed.
Slackening the nuts straightens it back out...doesnt really make sense to me.
Is there something that im missing here or am i just being silly? .
ive come to the conclusion that its not really a truss rod as such like the kind in modern guitars, but a strengthening bar of some sort?
can anyone shed a bit of light on this
?.
