The young woman has made herself comfortable. The seat back is folded far back, the legs are on the dashboard. Your friend drives just 80 km/h, more is not possible in the traffic. Suddenly has to brake but does not manage to avoid the crash. Fender bender! The driver escapes unharmed, protected by airbag and seat belt. But his young girlfriend is in a bad way. First she is catapulted with both legs into the windshield. Both ankles are broken, the legs are full of cuts. Then the airbag threw the legs upwards with full force, the body slid forward at the same time. The result is a pelvic fracture. The young woman is lucky that her neck is not broken.
At an impact speed of 50 km/h, the car occupants are accelerated up to 30 times their body weight. Only from a speed of 25 kilometers per hour the airbags shoot out of their hiding places. Before, the safety belt alone is responsible for minimizing the consequences of the accident. It reduces the risk of serious or fatal injuries to 50 percent. The airbag manages another quarter. Not a bad result! Despite this, several thousand car drivers are killed in accidents every year in germany alone.
Backrest as steep as possible
Seat belts, pre crash safety system, electronically controlled braking systems, front airbags, side airbags, top and bottom airbags, and more. The cars are packed with safety equipment. But if you don’t sit properly in your seat, even the most sophisticated safety systems won’t help you. When a car hits an obstacle, the airbag, the safety belt and the yielding steering column work together. As soon as one component is not used or does not function, or the passengers are not seated correctly, the entire safety system is ruined, because it is always tuned to this one optimal seating position. And if you ask the experts in german motoring, such as the legendary multiple rally world champion walter rohrl, or the five-time DTM champion bernd schneider or michael schumacher, they all have the same answer: the headrests must be pulled out so far that they are roughly level with the head height.
