The primary purpose of the active safety feature is to reduce the danger of a collision between the car and an obstruction. To improve occupant safety, active safety systems must be included on all new vehicles; nonetheless, not all incidents are preventable. The frequency of incidents on the road has recently increased in tandem with the number of cars, making it critical to investigate the crashworthiness of a vehicle because human life is at the top of the priority list. This study examines an occupant's responses prior to a crash event, as well as studies into how occupant posture influences injury data.
Most of the existing research focuses on the pre-crash event or the occupant's optimal seated position. However, it is critical to understand an occupant's reflex or behavior during the pre-crash event, when the occupant is typically not in an appropriate seating posture due to the panic reflex. As a result, an occupant's reflex in a panic situation will change their seating posture, affecting their injury parameters. The study will be based on the finite element crash simulation methodology for accident situations in compliance with the FMVSS rules. A comparison of injury parameters between a typically positioned occupant and an out-of-position occupant is presented. As a part of future work, we can consider restraint system method for reducing injuries to an occupant in a crash. A parametric study of the restraint system can be performed to identify strategies to reduce occupant injuries. One such example is the crisscross seatbelt. Existing restraint system solutions can be fine-tuned based on occupant injury levels in various seating positions.
