IN IN929DE2014A
This invention relates to a novel B-pillar of vehicle with variable stiffness to improve side impact comprising a shorter inner panel and inner reinforcement and novel door hinge reinforcement spot welded to each other. It is associated with the following advantageous features:- -To improve side crash performance of vehicle. -Transfer of crash load to lower part of B-pillar due to less stiffness of B-pillar lower. -Meets target of B-pillar upper intrusion, B-pillar lower intrusion and intrusion velocity to fulfill the requirements of side impact performance. -Light weight thereby making the B-pillar cost effective. -Less number of spot welds, which results in less assembly time and cost.
