Do you know why safety seats should focus on age-specific seats?

Children of different age groups have different physical structure characteristics and different requirements for child seats. It is difficult for the same child seat product to provide excellent protection for children of all age groups. For newborns, because the cervical spine and lumbar spine have not developed, their bodies are relatively soft. After 9 months, they can start to stand upright and walk, and children aged 3 to 4 can go to kindergarten. Because children have obvious differences in body structure at different stages, it is necessary to choose infant car safety seats with targeted functions and specifications according to the characteristics of age groups, so as to provide maximum protection for children.

For example, according to the EU ECE R44/04 child safety seat standard, infants weighing no more than 13kg (in the ECE R129 standard, the recommended height is no more than 87cm) are recommended to ride in a safety seat that supports reverse safety. Because the baby's cervical spine and skull are very fragile in this period, and the weight of the head accounts for almost 50% of the body weight. If it is installed in the same direction, once the emergency brake is encountered, the baby's body will rush forward, and the center of gravity will move forward. The head will also move forward, which can injure the neck from a large impact and, in severe cases, result in fractures. When the reverse installation encounters an emergency brake, the inertial effect of rushing forward becomes a backward effect, while the safety seat is behind, and the head device, neck device and backrest device of the seat can all control the head, neck and back. The waist and waist are well supported, thereby reducing head and neck damage and reducing the risk of injury.
