Case study for tibia execution & improvement for codriver foot region

Vehicle safety systems are divided into two type active safety system and passive safety system. Active Safety features comprise of technologies that actively work and sense the driving dynamics and real-time road conditions to prevent or mitigate an unfortunate crash viz. ABS, EBD, ESP. Passive safety features come into play in the unfortunate case of collision. The primary objective of passive safety features is to mitigate collision impact and injuries to occupant that may arise out of it viz. Airbags, Isofix, pretensioners. Also, Passive system includes energy absorbers & foot area foams which restrict travel of to avoid/reduce injury. This area is designed to absorb and dissipate energy during a collision, protecting occupants by allowing controlled deformation and reducing the force transmitted to the passenger. In case of accident, codriver legs would accelerate in the direction of impact which could result in mild to severe lower leg/tibia injury. In vehicle front & rear floor area covered with floor insulator and carpets. Co-driver would not have any dead pedal to restrict his leg acceleration in case of sudden impact. As resting of legs on flat carpet would cause an inappropriate and sudden forward movement during impact which could cause severe injury to co-driver occupant tibia. In this paper we have covered design improvements incorporated in front carpets for co-driver to mitigate injury and improve overall BNCAP tibia score during frontal crash. We have introduced stiffener pad made up of foams which would cover hard points on codriver side to avoid exposing of it during crash to occupant.
