Self Study Program 410 – Occupant Protection – Passive Systems

VAG SSP 410. The technical development of the motor vehicle has also seen a continuing increase in engine performance. This positive development, in combination with increasing vehicle density on roads and traffic congestion, has led to everincreasing demands on driver alertness.

Despite the many improvements that have been made with respect to active motoring safety, especially in recent years, accidents can never be  completely ruled out or avoided. For this reason, current research has been increasingly focusing on technical solutions for the protection of vehicle occupants in an accident. The first step in this direction was taken during the late 1950s with the introduction of seat belts designed to hold vehicle occupants in their seats during a collision. In the early 1980s further progress was made with the introduction of airbags designed to cushion vehicle occupants during a collision. These systems have been the subject of ongoing development and improvement.

Today’s vehicles are very different to the vehicles of earlier generations with respect to their interior equipment. In the above illustrations this is best evidenced by the dash panel and the steering wheel, which today are specially designed to accommodate integral airbags.
