After the introduction of the Thorax Airbag (TA) and the Head Protection System (HPS) by BMW there has been a significant reduction of injuries in real-world collisions. Comparison of similar collisions (in-depth collision analyses) of vehicles with and without HPS/TA indicates that the effectiveness of the system was credible. Minor injuries (AIS 1) increase while serious injuries (AIS 3+) are reduced. Based on the limited cases available, a proper statistical sampling could not be achieved at this time, however the results are to be understood as indicative of a trend.
