Hi, I have a few questions about the Anti-rebound bar for the Britax G4 seats.
1. Is it required RF?
2. Can someone with a G3 add it? would it make the seat safer? What is different between the G4 and the G3 Marathons that makes one requiring the bar and the other one not?

Thank you for helping me understand!

Does anyone know? What is different between the G4 and the G3 Marathons that makes one requiring the bar and the other is safe without it?

Our standards changed in Canada several years ago and seats now have a rebound standard to meet. So any seat made after the new standards went into play have to meet the rebound component. Some seats use anti-rebound bar to pass the test, some have added bolsters on the sides, there are various design techniques used.

Thank you! So am I understanding correctly? the Marathon G3 and G4 seat is the same but the standards changed so they still allow you to use the G3 without the ARB just because it was sold before the standard changed but it safer with the ARB?

Also other brands like say Graco or Cosco have different features that makes them meet the "no rebound" standards like the Britax with ARB and the ARB is not an extra safety feature Britax has?

The addition of the ARB came in mid-2014, well after the 1-Jan-2012 implementation date of the standard change. We don't know why Britax changed the requirements when they did, or if anything structurally was changed with the seat.

ALL seats on the market today pass the anti-rebound requirement, but not all do it in a visible way. Some have ARBs like the G4.1s, Clek Foonf, Clek Fllo, Peg Convertible, and some rear-facing only (infant) seats. Others do it with pronounced bolsters on the front corners of the seat, and others manage it with the shape of the underside. The Evenflo Titan 65/SureRide and the Evenflo Sonus both have a velcro strap on the underside that the US versions don't have, so presumably that's to do with managing rebound. Some RFOs require the carry handle to be up to manage the rebound.

With the Canadian 2012 changes, Britax required the tether be used rear-facing. Then there was an uproar because most vehicles don't allow it, and there is not always a good place to use it. So they made an ARB instead. And now they no longer recommend using the tether rear-facing.

No, the G4 RF tether requirement didn't come until the first run of G4 seats in December 2013. I had one of the first Advocates off the line and it required RF tethering. They then added the ARB after the loud uproar.

OK so conclusion: with the G3 you are allowed not to use the ARB just because... but it makes the seat safer with the ARB? The G4 has to be used with the ARB to make it as safe (or meet the same no rebound standards) as other brands (with other features that make them not rebund)? It is not an extra optional safety feature Britax has (because that is what BabiesRUS is telling people, a "gadget" is the word she used)...

Any seat made before standard changes, can be used as per the rules prior to the changes. Transport Canada thinks a seat is after meeting the rebound standards, else they wouldn't have implemented the new standard. So if the G3 allows the ARB bar, I'd likely use it. And if the seat requires it, it is not optional and not a gadget. And yes, all current seats have some form of anti-rebound. If BRU says the ARB bar on the Britax seats is a gadget, then so are the all the other measures used to prevent rebound on other seats.
