Most wiper arms have a single pivot point at the base where they attach to the gearbox splines to allow the arm to be moved for screen cleaning or blade replacement.
Older style wiper blades have a multi-pivoted structure that applies pressure to the rubber blade at several points to allow it to flex to follow the curve of the glass, newer style "beam" blades typically have a single pivot point where they attach to the arm but are built using a flexible curved frame that allows the blade to flex and apply pressure evenly across the length of the blade.
bsmy84 - are you using a genuine Suzuki blade? It's been my experience with rear screen wipers that many of the aftermarket blades do not flex enough to follow the curve of the glass.
Thank you for the thoughtful and clear response.
In answer to your questions:
I believe my arm is the "beam" type. (I'm a little confused because I think you used "blade" where you meant to use "arm.") That's what the arm looks like on the underside. So, I'm almost positive that if one were to try to bend it, it would break before bending. It also has the newer single pivot point.
Now if you're talking about the wiper blade being a "beam" type, I'd have to take a close look at it to see if I understand what you mean. However, if memory serves me right it has a multi-pivoted structure to where in theory it should press down evenly across the surface of the glass, which it does not the last 3+ inches.
I believe the rear blade is a genuine Suzuki blade, but I can't be positive. I bought this SX4 used (one owner) from a CarFax dealer who claimed the whole rear wiper assembly was the original.
The new arm is aftermarket, but as far as I can tell it's identical to the original which I still have. The arms are pretty simple and straightforward, as you probably already know.
As for using a genuine Suzuki blade, I don't know where I'd find one of those. The former local Suzuki dealership is a dealer for another make or makes.
