Traffic injuries are an important public health issue. To prevent these injuries, safety systems in a vehicle are recognized as valuable tools. These safety systems are active before and during a crash event. Passive safety is one such safety tool which comprises of occupant restraint systems to prevent fatal injuries during an event of a crash. To improve the real life safety further, active safety systems plays an important role in mitigating the real world accidents. Moreover, effective integration of active and passive safety systems has a potential to further reduce car occupant fatalities. However, in the recent developments in India towards road safety, vehicle safety standards are oriented more towards passive safety. In the present work, road accidents data from India between 2005 and 2014 are studied, to estimate the major mode of accidents and factors influencing the fatal injuries. Technological and human factor interventions are derived from these accidents statistics.

For the purpose of effective occupant restraint, seat belt anchorage test is devised to prevent any failure at the anchorage locations during vehicle crash. In India Seat Belt Anchorages (SBA) certification test is mandatory for M and N types of category vehicles with regards to forward and rearward facing seats in the vehicle. During the development phase failure at seat anchorage location was observed in physical test, which resulted in vehicle not meeting the regulatory requirement. This phenomenon of anchorage failure was captured through Finite Element (FE) simulations and correlation was done to understand the root cause of failure for future development. Computer Aided Engineering (CAE) based design proposals were developed by considering various parameters which influence the load path and force distribution at seat belt and seat anchorage locations.
