The extra piece on the wiper uses the force of the wind to keep the blade against the window.

Default The piece that is on the wiper arm...

Here's a possibility... it uses the wind pressure as a downward force to keep the wiper blade in contact with the windshield when used at highway speeds. That's about the best explaination I can think of.

yes if you are talking about the curved piece that is attached to the wiper arm, it is for better contact with windshield at autobahn speeds..

Default It keeps the blade stable at vertical when going very very fast (120+MPH)
