Got it - I'll have to take a look at these when I get home, can't see the links at work.
But from your description - sounds like the wiper arm itself got twisted somehow. That or the spring that holds the arm against the glass has somehow weakened or come loose. Did the original wipers get stuck/frozen on the windshield in the past or were forced to push lots of heavy snow these past several weeks?
Might get lucky and be able to use some pliers or adjustable wrench (tape the jaws with some tape to prevent them from scratching the wiper arm) and twist them the other way (ie, bend them toward the windshield.
If you are unlucky, like my wife's car (she tried to run the wipers when they were full on frozen to the windshield) - the metal arm closest to the wiper blade actually separated and twisted from the bottom half of the wiper arm - had no choice but to replace the whole arm ($105 for right, $95 for left).
More than likely, the springs got weak. Supposedly, you can just replace the springs - but I have not found a good source for those. I've heard that some CARQUEST places will replace the springs for you (you buy the springs, they install with no labor charge) - but no idea the costs of the springs themselves.
