Resumo
A segurança no trânsito para o transporte de crianças em veículos depende do uso correto de sistemas de retenção infantil (SRI). Esse dispositivo é essencial para prevenir lesões graves, como traumatismos na coluna cervical, que ocorrem devido à aceleração da cabeça deste passageiro durante as colisões. Os sistemas de retenção infantil são projetados para distribuir as forças de impacto, visando proteger a integridade do corpo da criança. As crianças de 1 a 4 anos são particularmente vulneráveis a esses tipos de lesões em um acidente automobilístico porque sua musculatura e estrutura óssea ainda estão em desenvolvimento, o que aumenta o risco de lesões na cabeça e no pescoço durante impactos bruscos. A utilização de sistemas de retenção para crianças (SRI) voltados para trás é frequentemente sugerido por associações de medicina, como a American Academy of Pediatrics (AAP), devido à maior proteção contra danos no pescoço e na coluna cervical em colisões frontais. Este posicionamento do dispositivo de retenção infantil deve ser mantido até que a criança alcance os limites de peso ou altura estabelecidos por leis. Contudo, crianças de 1 a 4 anos muitas vezes ultrapassam esses limites, sendo obrigadas a mudar para assentos voltados para a frente, o que eleva os perigos nesse período crucial de desenvolvimento. Por outro lado, crianças de 4 a 7 anos são menos suscetíveis devido à sua estrutura corporal mais sólida e resistente. O foco principal de nosso estudo é a segurança no transporte de crianças de 1 a 4 anos, devido à vulnerabilidade cervical e ao tamanho reduzido. Para isso, foi projetado um modelo de melhoria da cadeirinha infantil que, nas simulações realizadas no software PAMCRASH, demonstrou uma redução de 42% na força de tração Fz aplicada a coluna cervical da criança durante a colisão. Esse novo modelo de SRI apresentou uma redução de cerca de 750 newtons em comparação ao SRI original.
Traffic safety for the transportation of children in vehicles depends on the correct use of child restraint systems (CRS). This device is essential to prevent severe injuries, such as cervical spine trauma, which occur due to the acceleration of the child passenger's head during collisions. Child restraint systems are designed to distribute impact forces, aiming to protect the integrity of the child's body. Children aged 1 to 4 years are particularly vulnerable to these types of injuries in car accidents because their muscle and bone structures are still being developed, ncreasing the risk of head and neck injuries during abrupt impacts. The use of rear-facing child restraint systems is often recommended by medical associations, such as the American Academy of Pediatrics (AAP), due to their superior protection against neck and cervical spine injuries in frontal collisions. This positioning of the child restraint device should be maintained until the child reaches the weight or height limits established by law. However, children aged 1 to 4 years often exceed these limits, requiring a transition to forward-facing seats, which heightens the risks during this critical developmental period. On the other hand, children aged 4 to 7 years are less susceptible due to their stronger and more resilient body structures. The focus of our study is the safety of children aged 1 to 4 years during transportation, considering their cervical vulnerability and smaller size. To achieve this purpose, we designed an improved child car seat model which, in simulations conducted using the PAMCRASH software, demonstrated a 42% reduction in the Fz tensile force applied to the child's cervical spine during a collision. This new CRS model achieved a reduction of approximately 750 newtons compared to the original CRS.
