The S Stand Appeal

Okay here's my problem.

I sell and talk a lot about these:

When i talk about the stand part of the iPhone there is a word. Look at how it works. The stand is just a piece of plastic shaped like an S. This can only stand the iPhone up because of the weight distribution of the phone. The phone leans into the arch of the s, pushing the furthest away point into the table.

My problem is that there is a word for this, and I cannot, for the life of me think of what that word is.

I've heard the word used before in regards to self-defence because a lot of the martial arts use the limited agility of bones — bones can only bend in a certain way and if you bend someone's arm-bone in a certain way they will be forced to release their grip on you. Or something like that.

I have an appeal... help me find this word.
