Another car seat question

[sunshine_sieben]

Thanks for the tip, Frank. How does the anti-submarining design stop the head from slumping forward? Doesn't it stop the child from slippinng down in the seat and consequently the seatbelt from crushing internal organs in the event of an accident?
Oh, and I tried the Maxi Cosi link which actually took me to a baby store and there was nothing on there about the new Maxi Cosi. Also, the Maxi Cosis I know from Europe have a rear-facing baby capsule that fits onto the travel system. But once the baby is too big for that, the travel system won't work anymore. Of course Maxi Cosi make other seats, too, but they won't fit into a travel system.
