The glove compartment is home to the new security dimension for the passenger: In the place of this small storage area the Mercedes-Benz engineers bring an Airbag – one of the novelties of the brand at the International automobile exhibition (IAA) in Frankfurt am Main from 10. to 20. September 1987. This Innovation added as a coherent block, the previously established restraint systems from Mercedes-Benz, the driver Airbag and the belt tensioner. With the additional Airbag for the front passenger, the Stuttgart-based brand offers a protection for the occupants, the time in the world no other manufacturer offers.
Premiere of the passenger Airbag first in the S-class saloons and Coupés of the 126 series. These are from model year 1988 with the new special equipment can be ordered, which is only available in combination with the driver-Airbag, in Germany 4.617 DM. The driver’s Airbag alone costs 2.348,40 DM.
From 1979 to 1992-built Generation of the Mercedes-Benz S-class is definitively one of the pioneers of the Airbags. Because the driver’s Airbag first offered in the model series 126. Mercedes-Benz has been providing this ground-breaking solution for the passive safety of 5. to 15. In March 1981, the international automobile Salon in Geneva. Thus, the Stuttgart-based brand is the world’s first manufacturer who introduces the 1971 Patent pending System Airbag in the automotive Series production. The driver combines an Airbag with a belt tensioner for the front passenger. In the price list, the driver Airbag will be available from July 1981, he is in the 126 series for 1.525,50 DM available. Already in January of 1982, the System for all Mercedes-Benz passenger car models for the price of 1.570,70 DM available. In October 1992, drivers Airbag and Anti-lock braking System ABS car, finally, to the standard equipment of the People with the star.
The 30 years ago, presented at the IAA passenger Airbag is starting in September 1988 also in the models of the 124 series – the later E-class available. He made a name for itself as an effective protection technique in terms of passive safety and car to August 1994, together with head restraints in the rear standard equipment on many Mercedes-Benz Passenger. From the start, the manufacturer stressed that the passenger Airbag supplements the protection provided by the three-point safety belt, but in no way can replace. The belt is mandatory at this time already, since 1976, since 1984, their failure to comply will be fined.
The combination of both protection systems provides for a significant increase in passive safety, such as Tests with dummies to show: By the combined System, seat belt with pre-tensioners and front passenger Airbag belt the risk of injury in the chest and head area compared to the safety with pre-tensioners alone, about one-third more reduced. Be assessed in the Tests and in particular the impact of the accident on the tissue (Viscous Tolerance Criterion, VTC) and the head (Head Injury Criterion, HIC).
Five Kilograms Of Safety
In comparison to the three kilograms of heavy Element by the driver airbag, which is housed in the steering Wheel, the weight of the in the place of the glove compartment built-in unit of the front passenger airbag in the S-class model series 126 of five kilograms. This is partly due to the fact that because of the larger distance between the Airbag and the human body, the volume of the life-saving air bag almost tripled, it must be: It is in the S-class 170 litres instead of 60 litres for the driver’s Airbag.
In principle, the technique of 1987 presented the Innovation, however, it resembles the tried-and-tested driver Airbag: If the above the gearbox built-in triggering device (“Crash Sensor”) detects a serious accident, it triggers the two of the Airbag housed inflators. This produce made of pelleted solid fuel to a gas that inflates the Airbag abruptly. Its shape is selected so that it protects the passenger from an impact, both on the dashboard as well as on the A-pillar.
The trip unit detected collisions, and determine their Severity on the basis of two predetermined Thresholds. The first threshold is exceeded, triggers the device first of all the belt tensioners. When you Reach the higher threshold of the front passenger activated Airbag. The two gas generators, as ignition at a distance of 15 milliseconds, so that the air bag from the inside rubberized polyamide fabric filled with a controlled pressure increase. The vehicle electronics also checks whether the passenger’s assigned seat, or free. Because if the Sensors in the seat and into the belt buckle with a free seat display, and will not trigger the passenger Airbag in an accident.
Continuous research for the security
The passenger Airbag is an important element in the continuous process of safety development at Mercedes-Benz. The first testing of a comparable restraint systems for the front passenger starts at the Stuttgart-based brand almost two decades prior to the introduction in series production. So, in 1971, Hans Scherenberg, member of the management Board of the former Daimler-Benz AG and head of overall development and research reported earlier in the year, on-going testing of the development Department: “The passenger, who was protected by a waist belt and air bag, meets all of the requirements of the specifications.” As a reference, the U.S. Federal Motor Vehicle Safety Standards, of which the first regulations on 1 serve. March 1967, be adopted for the model year in 1968. 1975 Mercedes-Benz shows at the IAA in Frankfurt am Main the current state of research on the Airbag. Strap is presented with an “air bag for driver and front passenger as a possible Supplement for safety”.
The Airbag is
The Airbags for the driver and front passenger through the industry quickly, as a life-saving technology. Since the Airbag modules, through the continuous work of the engineers getting smaller and smaller, they can also be placed in other Places of the vehicle. To achieve, for example, a comprehensive protection in lateral collisions: Mercedes-Benz introduces in 1993, a side Airbag as a study, in 1995, the Sidebag comes as optional equipment in the first E-class on the market. More innovation steps Windowbag (1998), Head-Thorax side airbag (2001), Kneebag (2009), Thorax-Pelvis-Sidebag, Beltbag and Cushionbag (2013), as well as adaptive Airbags for the driver and front passenger with two-stage, time-delayed triggering, depending on the sensierter Severity of the impact and the adjusted seat position. So Mercedes protect-Benz passenger cars, their drivers and passengers today, with a sophisticated System of up to twelve Airbags.
