My seat uses LATCH (LUAS) so I am not as familiar with the seatbelt installation. I'd really suggest that you have someone take a look at it. If you Google "car seat clinic" +Where you live, I am sure you will find some information.ed3120 said:It's an infant, rear facing seat. We secure the base with the lapbelt part of the seatbelt, but it is not enough to keep it from tipping.
A properly mounted car seat (disclaimer: I only have experience with LATCH (LUAS)) will not move significantly in any direction. If it moves at all, it isn't installed correctly. They say "more than one inch," but ours moves even less than that, even toward the seatback.kmoose said:Rear mounted child seats WILL tip back towards the rear seatback regardless of installation. They are supposed to do this in a collision to help absorb the energy of the collision. This is why it is CRITICAL that if you use a "bucket" style seat the handle is put down (not left up as for carrying the infant seat) as the handle can seriously injure the child. Can't tell you how many people you see driving along with the handle up.
A buddy of mine is a firefighter and does those clinics. Even with LATCH - and we've used the rear anchors in Canada since the 80s - he says that he figures about 75% of car seats are incorrectly installed, and about half of those are so bad (dangerous) it would be safer for the child just to ride on the regular seat wearing the seatbelt.
If it is tipping side to side it is incorrectly installed. Every car in North America has had LATCH since 2002 and every car seat has had the installation system for latch since before that. Car seats are only good for 5 years regardless of what the manufacturer stamps on them, so any seat you are using in a 2010 Escape should easily mount with LATCH. Make sure the adjustable part of the LATCH strap is on the left side of the vehicle (drivers side) regardless of seating position as well to ensure it stays tight.
