Pedestrian Safe and Impact Resistant Headlamp Design Through a Novel Energy Absorber Ring Concept

As the pedestrian impact regulations are continuing to evolve, there is a growing emphasis on each and every component of a vehicle front to be pedestrian friendly. Traditionally pedestrian safety during an automotive impact is ensured through bumper, grill, fender and hood. However, the headlamp design was not under the same level of consideration as compared to other frontal components. To make pedestrian safety complete, the headlamp also needs to adhere to the pedestrian safety regulations.

A novel energy absorber ring (EAR) concept was developed to make the headlamps pedestrian friendly. The proposed EAR concept was found to improve the pedestrian safety and low speed vehicle damageability performance. It was also observed that the proposed concept reduces the replacement and insurance cost.
