A few days ago, my kids or sister-in-law took the back seat loose in my 240D while 'fishing' for the seatbelts. Now I can't seem to get it back in place. I thought I had it latched properly the other day, but it slid out this afternoon when I hit the brakes a little too hard.

Am I missing a trick to this? Or am I just not holding my mouth right?
