It's impossible to find any information about this system, I have search all over the internet, but couldn't find anything, so here's a little something, that might come in handy for you who are struggling finding a least a photo of this damn thing!

A view on how it looks inside. This one, sitting on a W212 2012 factory mounted, was stuck could not be retracted. A locking pawl was stuck, which has damage the plastik thing I'm touching in the video. Some ingenuity (humble me) fixed the plastic part and now it works!
