Unique protection for the neck and chest
Despite good planning and careful driving, you can never prepare for a collision. To protect your child's sensitive neck area in case of a frontal impact, Britax Römer has developed a shock-absorbing foam pad. It prevents the impact of your child's chin on their chest, absorbing up to 30% * of the energy. A jerky forward head movement is reduced and the neck is protected. At the same time, it provides additional padding around the edges of the seat belt.

Advanced Side Impact Protection – SICT
Our SICT offers superior protection to your child in the event of a side collision. It reduces impact forces by minimising the distance between the car and the car seat and deforms to absorb the energy before it reaches your little one. To benefit from the protection, simply adjust the SICT on the side of the car seat closest to the door. SICT reduces the side impact forces by up to 40%*.* Britax Römer internal tests and simulations
The SecureGuard helps to protect your child’s delicate abdominal area by adding an extra – a 4th – contact point to the 3-point seat belt. By keeping the lap belt in an optimal position over your child’s pelvic bones SecureGuard helps reduce abdominal forces in the event of a frontal collision by up to 35 %*, and at the same time allows your child freedom of movement during the journey. *Britax Römer internal tests with a Q6 dummy, representing an average 6-year-old child
