The 125-year-old automotive history is full of inventions. One of the biggest and most important without doubt is one of the airbag, which is after the seat belt is the most important life-saver in an accident. In March 1981, Mercedes-Benz the milestone along with the seat belt tensioners at the Geneva Motor Show, the first time in a vehicle of the former S-class.
Just one year later, both security systems as optional equipment passenger car brand are available. In 1992, the driver is then standard in all Mercedes-Benz models, 1994, the passenger airbag as standard safety equipment follows. The breakthrough inventions were preceded by 15 years of development work.
The research started on the airbag from Mercedes-Benz in 1966, practical experiments began 1967th Thus reacted to the then rapidly rising number of accidents. Extra weight given to research at the new restraint system to require the plan of the United States, from 1969 for each car an automatic occupant protection system.
The principle of the airbag, the driver and passenger protection in an accident, has been already registered in the 1950 patents. Were the pioneers here, especially the German Walter Linderer (Patent DE 896 312 of 6 October 1951) and the American John W. Hedrick (U.S. Patent 2,649,311 dated 18 August 1953).
More than ten years, the "inflatable container in the folded state, which inflates automatically in case of danger" (as Linderer describes his invention in the patent text) object of study in order to develop it for series production. The work of the Mercedes-Benz engineers and their colleagues at other car manufacturers and suppliers in the 1960s, is first of all basic research, for devices with which the idea from the 1950s could be carried in a passenger car, there was not.
In particular, the sensors and gas production featured the largest problems dar. extradited When American manufacturers first test car fleet with air-powered air bags, perform these restraints - they are an alternative thought to the belt - some serious injuries and sometimes even deaths.
Therefore, the planned introduction in North America was then moved further and further. The security experts at Mercedes-Benz therefore use for the production of the gas to drive rates, not stored pressurized gas. From 1967 to the practical experiments were carried out for gas production of chemicals as they are so similar uses as a solid fuel for rockets.
Unlike gas-filled cartridge, the cartridge proves to be reliable and fast. The resulting mixture consists mainly of nitrogen and inflates in a split second on the existing fabric of a special air bag. Another important step taken by Mercedes-Benz takes place: The air bag is not in Stuttgart developed as a standalone restraint system, but always seen in conjunction with the seat belt.
To print that comes in the internationally used abbreviation for airbags SRS, which stands for Supplemental Restraint System "(" additional restraint system "). "The effectiveness of the air bag system in conjunction with a lap belt and head restraint during frontal or rear collision can be described as good," it says in 1970 promising the key findings of the early attempts are included in the patent DE 2152902 C2, which the then Daimler-Benz AG on 23 October 1971 logs.
It already is the operating principle of the new technique described as she walks ten years later in series: sensors register particularly high delays, which are typical for solving conflicts, and from the airbag mechanism. This ignites a propellant charge (at the time of sodium, potassium nitrate and sand) that would result from the explosion, especially in gaseous nitrogen, and each turned a little water and oxygen.
The full performance, which showed the tests soon reached the airbag in combination with the seat belt. The 1981 also presented in Geneva Gutstrammer it is developed for the passenger and offered. Three years is the belt tensioners as standard for the front seats of all Mercedes-Benz cars he works - as the airbag - pyrotechnically: In an accident, the control also triggers a propellant charge, which attracts laid in a few milliseconds to automatic three-point belt of the seat.
Thus, the loose area between the upper body and strap, the so-called slack, tense. By the seat belt according to fixed, man with power is held in the seat and caught the kinetic energy of the collision. From 1995 on, the belt tensioners are then connected in all models with load limiters to the performance of the restraint system adapted to individual needs.
Over the years, the air bag modules have become smaller. They may also be placed elsewhere in the vehicle in order to achieve full protection even in side impacts. Mercedes-Benz, in 1993 a side airbag available as study 1995, the Side-Bag then comes as an option at first in the E-class on the market.
The window bag is standard equipment on the 1998, initially in the S-class. For the roadster, the Mercedes-Benz SL-Class 2001 of the head / thorax side air bag is introduced. In the S-Class W 221 series are adaptive airbags part of safety philosophy Pro safe. And the experimental safety vehicle ESF 2009 Mercedes-Benz in 2010 shows a completely new form of air bags: The Braking Bag is located in the vehicle floor and fires just before a collision.
He is based off the vehicle via a friction against the roadway and slow it up to the impact from additional. The production of the first S-class vehicles with air bag and seat belt tensioners began in 1980 at the Sindelfingen plant, after the presentation in Geneva, the series was 126 with the new optional then in July 1981 in the sale.
The combination of driver and passenger front seat belt tensioners was initially available only for the S-class and cost as an option for the sedan and coupe at the time each 1525.50 DM yet decided in the first year, buyers of the 2636 S-Class for the new security system . The move puts the bag on his victory and is now the standard in the automotive industry.
