Spanish layman's summary:

Este estudio realiza un análisis paramétrico de simulación con el objetivo de evaluar la eficacia de un airbag cervical para mitigar la extensión y la flexión lateral del cuello bajo distintos niveles de energía de impacto y de presiones de inflado del airbag. Además, se estudia la influencia de estos cambios en las métricas de lesiones de cabeza en dispositivos de prueba antropométricos comparando la cinemática y la dinámica de los sistemas.

English layman's summary:

This study conducts a parametric simulation analysis with the aim to assess the effectiveness of a cervical airbag in mitigating neck extension and lateral flexion under varying low impact energy and airbag inflation levels.The influence of these changes are studied in ATD head injury metrics  by comparing kinematics and dynamics of the systems.
