We’ve been waiting for clarification of this final ruling for an entire year and we’re just getting details this week – days shy of the Feb 27, 2014, implementation date. Many CPS Technicians and advocates have been aware that these changes were coming but we were also aware that there were petitions pending so we were all waiting for the final word from NHTSA. There was much speculation that implementation of these changes would be delayed or that NHTSA would increase the weight limits, but none of those things happened.

So… in a nut shell, here is what parents and caregivers need to know:

There are two changes to federal safety standards going into effect this week that will affect some carseats manufacturered on or after Feb 27, 2014. First is a new label requirement. While that doesn’t sound like a big deal – it actually is. NHTSA has ruled that carseats with a 5-point harness should not be installed using the lower LATCH anchors if the combined weight of your child and the carseat exceeds 65 lbs. In these cases, you should discontinue using the lower anchors in your vehicle to install your carseat and switch to a seatbelt installation instead when your child reaches a certain weight. The label will tell you at what point you should make that switch.

The concern is that the lower LATCH anchors in your vehicle may not be strong enough to restrain a very heavy child in a very heavy carseat under severe crash loads. It makes sense – mass is mass regardless of whether it’s the mass of the child or the mass of the carseat. Both are going to exert forces on the lower LATCH anchor bars when they are loaded in a crash.

If your carseat was manufactured before Feb 27, 2014 and the 5-pt harness has a weight limit of more than 40 lbs. please check your carseat instruction manual for guidance on LATCH weight limits. There may or may not be limits listed  - Dorel and Evenflo don’t generally list LATCH weight limits but Graco and Britax do. Also check this link to find out if your vehicle manufacturer has LATCH weight limits

Since parents probably don’t know how much their carseat weighs, going forward NHTSA is going to require the carseat manufacturers to “do the math” for you if there is any chance that the combined total of kid weight and carseat weight may be more than 65 lbs. Many carseat manufacturers are already listing LATCH weight limits on their seats with high harness weight limits.  Pictured below is the current Chicco NextFit label. The NextFit is rated up to 65 lbs in the forward-facing position but it weighs almost 25 lbs. Therefore according to the NextFit instructions you must switch to a seatbelt installation (plus tether) once your child reaches 40 lbs.

Not all carseats will have LATCH weight limits but it will be the responsibility of the carseat manufacturer to list one if necessary. For example, Graco knows exactly how much each of their carseats weigh and they know the maximum weight limits on the 5-point harness for each of their seats too.

  • The Graco ComfortSport harness is only rated to 40 lbs. and the seat itself definitely doesn’t weigh more than 25 lbs. so the new label requirement doesn’t apply to this seat. You can use LATCH (rear-facing or forward-facing) to the weight limits of a ComfortSport without concern.
  • The Graco Classic Ride is rated up to 50 lbs. with the harness but the seat itself weighs less than 15 lbs. so once again – the new label requirement doesn’t apply here and you can use LATCH (rear-facing or forward-facing) to the weight limits of a Classic Ride.
  •  A bigger, heavier seat like the Graco Nautilus will require this new label that tells parents when to switch to a seatbelt installation. The 5-point harness on the Nautilus is rated up to 65 lbs. and the seat itself  weighs about 20 lbs. so the label will probably tell you to discontinue installation with the lower LATCH anchors and switch to installation with seatbelt (plus tether) once your child weighs 45 lbs.

It’s up to you to keep track of how much your child weighs and to make the switch to seatbelt plus tether once your child exceeds the listed LATCH weight limit. It’s important to point out that this new requirement addresses weight limits for the lower anchors in your vehicle but does NOT impose a weight limit on the tether anchor. This is important because we always want you to use the tether if a carseat is installed forward-facing in a seating position that has a designated tether anchor.

Currently there are no infant (rear-facing only) carseats that are so heavy that they could exceed the new 65 lbs. combined LATCH weight limits.  So if you have a kid in a rear-facing only infant seat – don’t worry about these new limits.

However, there are a few exceptionally heavy convertible seats that also have high rear-facing weight limits and consumers who buy these seats (manufactured after 2/27/14) will find labels and instructions telling them what the LATCH weight limits are for rear-facing (and separately for forward-facing). Convertible seats that will be required to have rear-facing lower anchor weight limits will include Diono convertibles, Graco Smart Seat & Clek Foonf.  In some cases the rear-facing LATCH weight limit could be as low as 25 or 30 lbs. child weight.

The second change to federal safety standards that is also being implemented this week involves testing with the new 10 year old Hybrid III dummy. This dummy weighs about 78 lbs. and is 51″ tall. Any carseat manufactured after Feb 27, 2014 that has a 5-point harness rated beyond 65 lbs. will be required to fit this 10 yr old dummy and also be required to pass certain crash test performance standards using this dummy. Since the 10-yr-old dummy is huge – it won’t fit in most convertible seats, which is why you’ll see many carseat manufacturers backtracking on the maximum weight limits of their convertibles and some higher-weight combination seats too. Seats that may have been rated to 70 lbs. or higher in the past may now have a weight limit of 65 lbs. Some manufacturers have already backtracked to 65 lbs., others will be doing so shortly as the new requirements are phased in this week.

The Britax Frontier 90 and Pinnacle 90 will retain their 90 lb. harness weight limits as those seats are already tested with the 10 yr old dummy. We know Graco is working on a new Argos 80 (we reported on it from ABC) which will be taller than the current Argos 70 combination seat and will be reinforced to pass testing with the new dummy. When we have more details about other higher-weight harness combination seats, we will share them here.
