2000 Dodge Caravan seat belts problems

The driver of this vehicle lost control, causing a rollover, one of the passengers was sitting in the right half of the middle seat, this is a double seat which does not extend all the way to the door, the seatbelt for the middle seat is anchored to the side of the vehicle, not the seat itself, in this case when the vehicle rolled over, the door opened and the victim was ejected from the vehicle and was killed, this letter is from the chairman of the pima county child fatality review team, the owner of the vehicle…

I own a 2000 dodge caravan which is equipped with gen 3 seatbelts. I have two daughters, ages 1 and 4, who ride in my van daily. On at least three different occasions, one of the seat belts securing my daughters' car seats in has unlatched while I was driving and was I unaware of this until I stopped the vehicle to get them out. Luckily, no injuries have occurred yet; however, I cringe to think about what could of or what will happen if I am ever in an accident.
