What are those side skirts called?

I managed to damage mine and am looking for a replacement. I am referring to those bits of plastic sticking out on the bottom of the door. What would you call them? and where could I find the product code to search for a replacement?
Thanks

Thank you Mr. Spoon - I am trying to source some in liquid yellow.
Not easy at all.

 

No luck - can't find them anywhere

 

Yep, the dude could not even find them on his system.
