The award winning Aton 2 builds on CYBEX safety technologies to offer maximum protection with three unique safety features. The Load Leg prevents the seat from rotating forward, allowing the seat to perfectly support the baby’s head, neck, and body. It also transfers much of the energy to the vehicle’s floor, decreasing forces on your baby up to 50%.Secure European installation without the base uses a unique shoulder belt routing behind the carrier that makes this installation method as safe as using the base with Load Leg. Makes travel in taxis and on vacation safe and simple. The fold out Linear Side-Impact Protection devices start absorbing side impact forces as early as possible, channeling them through the shell. This greatly reduces force on your baby. Installing the base with the Belt Tensioning Plate makes a secure installation easy to achieve.
