Racetech have been designing race seats for more than 20 years and during that time, have seen many crashes both real-life and simulated. While frequency of motorsport fatalities in most categories is decreasing, they believe that still some way to go to improve driver safety.
Data collected from crashes shows that in preferred impact scenario, the drivers head, neck and torso should all remain in alignment. To achieve this, at the very minimum, it is recommended to use a seat with integrated head support, using a quality harness and wearing an approved HANS device. This is the accepted standard around the world.
