Safety, airbags celebrates 30 years

At the Geneva Motor Show 1981 Marcedes-Benz presented the first car built in series equipped with air bags and seat belts with pretensioners (essential for the proper effect of the inflatable pillow). The car was the S-Class and the period since 1982 these important active safety devices have entered the list of options for the entire range.

The patent dates from the airbag to many years earlier. Indeed, it is a patented back in the fifties, before the German Walter Linderer (October 6, 1951) and then by American John W. Hedrik (August 18, 1953). For over ten years, this device has had little practical installations. Mercedes-Benz has also embarked on extensive research since 1966, with the first tests in 1967.

Among the main stages of its development is the next patent of October 23, 1971 (filed directly by the Daimler-Benz) that contains the operating system: Some sensors record the violent deceleration that is felt in a collision and activates the mechanism airbag activated by an explosive charge that generates the gas needed to inflate the cushion.
