RAMP Bracket Angle Optimization Coupled with Improved Head Room 2024-26-0016

Restraint systems in automotives are inevitable for the safety of passengers. Curtain airbag is one such restraint system in automotives that reduces the risk of injury to passengers during crash, without which head injury is inevitable during side crash of a vehicle. So successful deployment of curtain airbag (henceforth called as CAB) is very important in automotive safety during crash.
This paper dwells about the optimization done in ramp bracket angle with successful deployment of curtain airbag. This optimization has paved the way for increasing the head-roominess by ~15% and to respect the safety and styling intent in the vehicle successfully.
Providing a ramp bracket at the lower bottom side of CAB guides the airbag successfully during deployment. Ramp bracket angle plays a vital role in guiding the airbag inside the passenger’s cabin without any obstruction. This paper challenges the conventional ramp bracket angle followed for CAB deployment with an alternate angle and has successfully validated the same. This paper also throws light upon the flushness criteria to be followed between ramp bracket and environment parts.
