Evolution of the Restraint Systems
Seat belts and airbags are restraint systems that have established themselves on a worldwide scale. These systems have changed a great deal over the years. Today’s sophisticated and effective restraint systems offer the occupants even greater protection in line with the situation in hand.
To make this possible, computers that use various sensors determine the likely accident severity as well as ascertaining the front passenger’s individual data. If the sensor system detects a small front passenger, it initially only triggers the first airbag stage, depending on the predicted impact severity, meaning that less air is injected into the airbag. If the system senses a larger front passenger, however, both airbag stages are triggered.
The engineers have also further improved the crash sensors
. By way of example, the Mercedes-Benz S-Class is fitted with a total of eleven sensors which provide data regarding the type and severity of an impact at an early stage and are able to differentiate between a frontal impact, side impact, rear impact, and rollover. Like the further developed restraint systems – seat belts, airbags, and head restraints – extensive innovations covering practically every aspect of the body structure and the passenger cell
provide invaluable assistance in critical situations.
