Good question. Not sure what you would call that! Some sort of foam insert. Part of the arm rest maybe.

 

Crash protection is what I was told. Not sure what exactly it's supposed to do in a particular crash, but that's why engineers put it in there.

I know various other makes and models also have a similar cube of material in some doors
I've also seen many of those just thrown away when they cause problems (like come loose and jam under the glass)

 

Crash protection and sound deadening.
