Child’s Safety Protection

Research by Children’s Hospital of Philadelphia et al found that “…head injury is the leading cause of death for children up to 12 years old involved in vehicle crashes and comprises 65% of injuries in both frontal and side impact crashes …”

The safety of your child is the first consideration in choosing any car seat, and Britax Marthon 70 convertible car seat has been designed with revolutionary safety features to provide maximum protection for your child in the event of a vehicle accident.

Britax Marthon 70 is built with Safecell technology that enables car seats to compress in a crash, greatly reducing a child’s centre of gravity, and this counters the forward motion of the car seat which would have propelled a child towards the front seat, causing injury to the child.

With integrated steel bars, Britax Marathon 70 convertible car seat’s connection to the vehicle is strengthened and this further reduces the forward motion of your child in the event of a car crash.

Incorporated in Britax child car seat design since 1996, the Side Impact Protection feature of the Britax Marathon car seat is generously layered with shock absorbing EPP foam that keeps the spine and neck aligned, and deep side walls that distribute crash impact and protects your child’s body from touching parts of the vehicle that may cause injury in a car crash.

Britax Marathon 70 Tether System

The tether on Britax Marathon 70 features a staged-release energy absorbing design that again slows forward motion, greatly reducing crash impact that may reach the child. It also features a two point attachment that reduces forward movement while firmly holding the top of the convertible car seat.

Britax Marathon 70 has a five-point harness that is tangle free, holds the child securely and distributes crash forces evenly across the strongest parts of the child’s body thereby minimizing crash injuries.

Front and side impacts are the most frequent sources of injuries in a car crash, and the extensive safety features in Britax Marathon 70 of convertible car seat work together to provide a child with the best protection a car seat can offer in a car crash.

Child Age and Size

Just as the BRITAX Marathon 70 convertible car seat is packed with important safety features for your child, one other feature that makes it very popular is, you guessed it!– Yes, it is convertible and will serve a child as he or she grows from baby to toddler.

This High-capacity convertible car seat will allow your child to use the same safe, comfortable, and secure five-point harness car seat from baby, through the toddler years, without the need to invest in a new car seat.

The BRITAX Marathon 70 can be used as a rear facing car seat for babies from 5 to 40 pounds, and as they grow into toddler, it is easily converted to forward facing car seat from 1 year and 20 pounds, up to 70 pounds.

Ease of Use

The safety features of a car seat may be highly rated, but if it is so difficult to use that it leaves you frustrated every time you strap in your child, there is a good chance that the car seat will not offer your child the protection intended due to improper use.

Britax Marathon 70 convertible car seat uses Premium lower LATCH connectors with push-button that allow you to easily install the seat in a vehicle using the LATCH system. The LATCH connectors are attached to the lower part of the child seat via a strap that is also known as webbing. The installation gives a reassuring audible click when the connector is securely attached into place.

All vehicles manufactured since September 1, 2002 in USA are required to have LATCH anchors for attaching Child car seats, but with BRITAX exemplary commitment to innovations in Child car safety, the LATCH connectors has been featured in BRITAX child car seats since 2001.
