Safety Features

Like the Marathon 70-G3, Boulevard 70-G3, and Pavilion 70-G3, the Advocate 70-G3 is equipped with HUGS Chest Pads and the Base both of which have SafeCell Technology that compresses to restrict a child’s body from making forward movements during a crash. The Energy-Absorbing Tether also minimizes the forward movement of a child by lowering the child’s center of gravity which bigger kids need and staged-release to slow down forward forces. The Integrated Steel reduces the amount of flexing that car seat could create during an impact and therefore the child will be strapped safely on the car seat.

Protecting children from making forward movements is one thing, but Britax tackled 360-degree safety and pushed further in protecting children from side impacts. They added True Side Impact Protection which includes the huge head restraint designed to make the children’s head aligned with the body and contained inside the car seat and contributes the impact forces throughout the body and minimize possible injuries. This is the same with the Boulevard 70-G3 and Pavilion 70-G3. Also they made sure that this Side Impact Protection minimizes any further injuries from protrusions that the vehicle may create during an impact. The side walls are well padded with EPP foam to help with cushioning the child during the crash as well.


Side Impact Cushion Technology

The main safety feature of the Britax Advocate 70-G3 Convertible Car Seat as compared to the other models in G3 line is the Side Impact Cushion Technology. This is in addition to the abovementioned True Side Impact Protection in which reduces side impact crashes energy by up to 45% more. This not only protects the child inside the car seat but it also cushions the adjacent passenger. The cushions are located in each side of the car seat. Be warned though, that because of this, the Advocate 70-G3 is wider than the other Britax convertible car seats. The Side Impact Cushion Technology has been designed, developed, and patented since 2009 on the Advocate 70-CS and is also applied on the Frontier 85 SICT Booster Seat.


Strapping Features

The features discussed below are also the same for Marathon 70-G3, Boulevard 70-G3, and Pavilion 70-G3. The Britax Advocate 70-G3 is equipped with tangle-free five point harness in which it can be adjusted easily without rethreading or disassembly or removing of the seat cover. It is further enhanced with another safety feature, Click & Safe Snug Harness Indicator to give you indication that the straps are pulled tightly enough to secure the baby in the car seat. It is then enclosed by an EZ-Buckle system that has two adjusting positions for growing child. That way the buckle always stays in front of the child and will not be sat upon or that you won’t have to fish it out when buckling or unbuckling your child. To make strapping your child much easier, there are simple Velcro on either side of the car seat used as Harness Holders. This will basically keep the straps away when you place your child in the car seat.



Installing the Advocate 70-G3

Like the Marathon 70-G3, Boulevard 70-G3, and Pavilion 70-G3, the Advocate Convertible Car Seat can be installed two ways – using the LATCH and tethers; or using the seat belts. Britax made sure that whatever you choose is based on the vehicle and car seat standards and made them much easier. The LATCH has an easy release button, kind of like what you use on the seat belt. When using the shoulder or lap belts, there are built-in lock-offs in the car seat when the part of the seat cover is removed. These lock-offs secure the vehicles seat belt and make sure that the car seat will not have necessary movements once it is strapped. To aid the car seat from further making any movements and slippage from the vehicle’s seat, the Advocate 70-G3 is also equipped with a contoured base that will grip the seat well.


Fabric Options of Advocate 70-G3

The Britax Advocate 70-G3 Convertible Car Seat comes in 5 different fabric options. They are Anna, Onyx, Opus Gray, Serene, and Zebra (left to right). The fabric is easy to clean and can be done so by not removing it from the car seat. It is not advisable to machine wash and dry clean it though because it may compromise the pads of the seat cover.
