25 years ago Mercedes-Benz was the first automobile manufacturer in the world to introduce the front passenger airbag in a series-production car. The technology debuted in the S-Class (model series 126) at the Frankfurt International Motor Show in September 1987. It elevated the safety standards in Mercedes-Benz passenger cars to a new level and thus represented yet another logical step by the pioneer in passive vehicle safety in a long line of outstanding innovations.
Mercedes-Benz had already introduced the world’s first fully operational driver airbag in a production vehicle in 1981 – also in a 126 model series S-Class. The Supplemental Restraint System (SRS), consisting of driver airbag and belt tensioner, was available as an option for DM 1525.50. It was the result of the rigorous work undertaken by corporate research that had started in the mid-1960s. When sensors detect a collision, a propellant charge is ignited and within a few milliseconds the nitrogen produced by this process inflates a bag made out of a special woven material. The resulting cushion protects people against impacting the dashboard. While the driver airbag is housed in the steering wheel, the front passenger airbag in its early manifestations occupied the spot where the glove compartment would normally have been. Thanks to refined and smaller airbag modules vehicles later regained the glove compartment.
The front passenger airbag introduced in 1987 utilised the same technology as the innovative driver protection system. It went on sale as an option on S-Class saloons and coupés in February 1988. Soon afterwards Mercedes-Benz also offered the front passenger airbag as an option in the mid-size model series 124. As early as 1994 the front passenger airbag became standard on all Mercedes-Benz passenger cars; the driver airbag had already been part of the standard equipment of all passenger car models since 1992. To further improve the protective effect afforded by airbags, the Mercedes-Benz engineers went on to develop additional systems such as the side airbag and the side curtain airbag in the years that followed...
