The increase in fatalities day by day due to vehicle crash is a great challenge for automobile industry. There are lots of safety enabled features has been developed such as seatbelts and airbags, which reduces the occupant injury in considerable amount. But the recent studies and statistics are showing that there is lots of fatalities are reported due to impact on interior components of automobile. To address this situation and to reduce the occupant injuries due to impact on interior components NHTSA designed new safety protocol FMVSS 201 to evaluate the head impact on interior parts. To meet these new protocol by maintain good design integration of parts requires certain procedures, which can be used by automobile manufacturers for designing safer vehicle. An attempt is made to study and analyze the head impact on upper roof of an automobile and come up with different design suggestions. The impact situation is evaluated by using head impact criterion of dummy. These attempts will be helpful to reduce the injury and also numerous design iterations can be reduced. This in turn reduces the total development time of an automobile.
