The performance of motor vehicles has increased continuously in pace with their technical development. In combination with the simultaneous increase in vehicle density on the roads, this positive development has also led to increased driver attentiveness requirements.

Despite the multitude of good ideas implemented, particularly in recent times, in the field of active road safety, accidents can never be ruled out or avoided entirely. Increasing research has therefore been conducted into technical possibilities for protecting vehicle occupants within the vehicle in the event of an accident. One initial step – implemented at the end of the 50s – was to restrain the occupants in their seats by means of seat belts in the event of a crash. At the beginning of the 80s, this progressed with the installation of airbags, which cushion the vehicle’s occupants during a crash. These systems have been
constantly extended and their functions improved.

The interior equipment fitted in modern vehicles differs significantly from that of previous vehicle generations. In the illustration above, this can be clearly seen from the dash panel and the steering wheel, which are designed accordingly in addition to the integrated airbags.
