This is a question I have been thinking about, and I hope I make sense.
I have seen people here talking about outgrowing highback boosters by height, and wondering which booster has the highest belt guides. My question is if that is really important when using a booster.
Logically, it seems like the same rules should apply as they do for a 5point: you should not have harness straps below shoulders. But, some seatbelts in cars aren't necessarily above even an adult's shoulder. It's quite possible that when an adult sits in a seat their shoulder is above where the belt comes out. I'm especially thinking of seats where the belt comes out from the top of the seat.
Also, what if the added height of a booster makes the booster's belt guides higher than the seat belt? Doesn't that trump where the child's shoulders are within the booster?
I know this wouldn't be an issue in every car/situation, but it's just something I was thinking about.
Do you think adults are unsafe/at risk for spinal compression if the seatbelt is not at or above their shoulders? Should people who have adjustable height seat belts in their cars always adjust them to be at or above the shoulder?
If there have been crash tests with dummies with shoulders higher than seat belts, I'm thinking it might not matter so much where the booster belt guides are in relation to a child's shoulder. I'm not saying it would be my first choice though.
I thought I would pose this question to all of you experts and see what you thought, hope it makes sense.
