We searched for ever to cure this ill. The Bentley shows mounting points for shoulder restraints in the back seat. You could not use this on the cabinet side. We finally found a child booster seat designed to work with just a lap belt. Fischer Price makes it and it is good up to 60lbs. We only have one of 4 cars that has rear shoulder restraints so this was
the best answer. As soon as she gets to be over 60lbs I guess I will need to start looking at those factory mounts and see how that could work.
hope this helps,
