i'm wondering if in the FF MA videos that the 6yo dummy may have been TOO TALL for the seat???

The 6yo dummy is technically too tall for the seat (shoulders over top harness slots), HOWEVER this is the dummy that federal law (both Canadian and US) requires to be used to test the seat due to the seat's weight and/or height limits. The law doesn't make any exemption for the dummy being too tall; the law says this is the dummy that must be used, and if the seat fails, the manufacturer isn't allowed to whine that the dummy is too tall for the seat and that was the reason for the failure. The manufacturer can raise the top slots, or make a seat that's strong enough in spite of the dummy being over the top slots (if that affects seat performance), or lower the maximum weight limit of the seat.

I had a big reply typed out last night and it got eaten when I clicked reply and c-s.org was temporarily down.

I'm just going to say it in short this time, since I don't have the time to type it all out again...

ALL seats certified to CMVSS 213 and 213.1 in Canada must meet ALL standards applicable to the specific certification and mode of installation regardless of the weight the seat is certified for.

So a seat certified to 65lbs MUST not exceed the maximum allowable head excursion when tested at the max certified weight, and must not have any other injury measurement exceed those allowed. Any standard that a manufacturer must meet to label a seat to 40lbs or 48lbs must still be met at 65lbs. There is no magical # that CMVSS 213 requirements quit applying at.

I have a question. In the video of the Marathon rear facing in the Kia Magentis (the first video) If you watch the video from the Left view you can see another seat and it appears that the head rest of that seat detaches. The only seat I know of with a detachable head rest is the True Fit, but this just doesn't look like a True fit to me (maybe its my poor video quality) Any speculations on what the seat is???????

It is the Safety 1st Intera 4-1. It looks like the headrest comes off, but if you see the right view of the crash (click on Intera - Kia Magentis), you can see why. HTH!

some carseat mfrs refuse to allow RF tethering for exactly this reason-- there is no such thing as a dedicated RF tether point, except in some swedish vehicles. they are all makeshift, and the end user has absolutely no idea how that tether point will hold in a crash. how can we as individuals be "confident" they will hold? on what basis can we make that judgment call? how is that any different from a DIY mom or dad using a home depot eye hook bolted into the floor as a retro-fit LATCH anchor and being "confident" that it will hold?



exactly.


All Swedish conventionally installed RF seats have a 55 lbs weight limit for rearfacing and tether straps. Isofix seats have an 40 lbs weight limit and no tether straps.

In other words, those tether points that you´ll find in Volvo cars are tested to 55 lbs. That´s 10 lbs beyond the limit of the Radians.
