I just noticed a part has fallen off the side of my passenger seat, and I'm at a loss how to put it back on. I checked the other side and found the part has fallen off that side as well. I cant tell if the top part of the piece goes over or under the seat back, and what keeps it in place. There's a tab on the inside of the piece, but I don't see a corresponding slot in the seat for it to fit in.
Here's a photo.
