Seat belt installation of a group 0 car seat

[redjumper]

I have a maxi cosi cabriofix seat for my baby and in one of our cars it needs to be belted in. I'm sure I'm following the instructions correctly but I'm still not happy with how it fits. The problem is the whole seat can tip forwards towards the back of the car's seat. There is the safety bar which would stop my baby being crushed against the seat but it's still surely unsafe for it be able to tip right forward like that. I've tried it in different cars and I've tried other group 0 car seats in the baby shops on their demo car seats and they all seem to have the same problem. Has anyone else noticed this? Am I doing something wrong?

Can you post a picture of how you have strapped in and a picture of it from the side to show where the buckle sits, It I can't help you someone else will be able to.

Don't worry - they are designed to move like that, yes. Even with isofix. Note that as the baby is rearfacing, in a frontal crash (which is what most high speed crashes are), the main impact causes the baby to be pushed further INTO the seat. It is the rebound when the baby and seat will move towards the back of the car. Your baby's head legs and arms would move towards the back of the car, while the torso is kept restrained by the harness; if the seat moves in the same direction it will keep him protected. Imagine if the seat stayed rock solid and your child's torso was restrained by the harness as his body flies towards the back of the car - that could cause internal injuries. As you say the handle stops the seat going too far.

If you look at some official crash test videos on youtube you'll see what I mean. They are designed this way.

you can see what happens in a crash - note how the baby hardly moves when the car first stops (but the child in the front facing seat goes flying forwards - note to keep your child rear facing as long as possible!). Then the baby seat rebounds and the carry handle stops it. fixings - and you can see it still moves forward a LOT when it rebounds just the same as when it is seatbelted in.

Thank you so much. That is the movement I'm referring to. It's so helpful to see the video and it quite reassures me. I was shocked to see the forward facing seat in the crash, I have two older children in seats like that and now that will be my worry!
