A top tether strap is a strap in the middle of the back of cart seats. It’s similar to the Q strap except it can only be used forward-facing and is mandatory for all car seats. It limits the distance your child’s head moves forward in a collision by 4-6 inches. Think of it as life or death. If you want life, attach it! It’s literally what keeps the car seat in place during a collision and prevents your child from suffering a severe head injury.
The top tether strap should always be the first thing you attach and the last thing you tighten. The place you attach it to depends on your car. It can be located on the back of the seat, the floor, the ceiling, the back dash… your car manual is your friend if you can’t find it. Most will have an anchor symbol. Cargo mounts were not built to withstand the forces of a crash, so you want to make sure it’s the tether mount and not the cargo mount. If you aren’t positive, check your car manual. You may need to remove your trunk cover in order to use the mount. I had to do that with my Volkswagen Beetle.
For those with trucks, even if you have found your tether mount, read your car manual for proper installation. Some trucks have different installations of tethers compared to other cars where you have to loop it through and pull it across to the other side of the car. Make sure you read your car manual for the proper installation method. Without proper installation, it won’t function as should.
In the picture below by Buckle up with Brutus, you can see the difference between using and not using the top tether. As you’ll see, the cars seats in this picture were attached using the LATCH System. However, the top tether applies for seat belt and lower rigid anchor installation as well.
The only time you should not be attaching the top tether strap is when you are on an airplane (as they don’t have top tether mounts), rear facing (a lot of people will start attaching the strap when they switch from an infant seat to a convertible seat just because it’s there, so they think they have to attach it, but it’s only meant when forward facing) and when you are using a combination car seat with a lap and shoulder belt (as the top tether only applies to people strapped in via a harness*).
Additional top tether notes: The Ride Safer Vest comes with a tether attachment. If you are using a lap only belt, you need to use it. When using a lap and shoulder belt, it is optional. It can be great for helping to keep squirmy kids in the right position.
Foreign car seats and top tethers: In Germany, they have what is called a Nachfolger HY5 inflatable car seat. It can be used for newborn up to the age of 5. It can even be used in the front seat as long as it rests against the dashboard with the airbag turned off. This car seat uses the top tether rear facing. Make sure to attach it when using this car seat. In Germany that is, as this car seat has not been approved for use in the United States.
*A select number of seats allow use of a top tether in booster mode. To know for sure for your particular car seat, read your car seat manual.
