560sl seat cover for when top is down
 

Hi, I have a 560sl that came with a cover that you can utilize to cover your seats when the convertible top is down, but I have no clue on how to install it. (The passenger side and driver's side are covered and you just unzip the drivers side to get in. It lays flat to door level.) I don't even know what it's called to look it up. A little help would be greatly appreciated.
