Why is the drivers side wiper such a complex item?

[iani]

Can someone please tell me why the drivers side wiper arm is such a complex piece of kit? I suppose I'm probably missing something obvious!

never paid much attention - but I assume it changes the angle of the blade part so that it can wipe the max part of the screen - if it did not would it be at the wrong angle at the top of its travel?

Mine broke returning from France last month. Taped it up at the next Aire what ever I did I couldn't get it to clean the glass at eye level. Luckily the rain had stopped.

So I assume you are right regarding angles

Got a new one from SOC spares not fitted it yet though

Thanks Giles, I need to get some new blades for mine as they aren't doing as well as they should.

Its to do with the curve of the screen, I think!

Giles is right. It is a pantograph mechanism so that it is parallel to the screen edge at the A-post. If you fit a passenger side arm to the driver's side, you will see why it is like that.
