Increasing the safety of passengers

Car safety systems already help prevent accidents, for example with a pre-tensioning system that allows you to re-tension the tension. safety belt on the body before the impact, then relax it in a controlled manner to ensure the airbags are deployed properly.
Euro NCAP crash tests will be required in the future more individual protection for each passenger of the vehicle: “The requirements for the adaptability of safety systems are growing both from the point of view of end-user expectations and NCAP testing criteria. Our new belt system makes it easier for car manufacturers to meet increasingly stringent requirements and, in particular, reduces the impact of accidents by adapting even more to each passenger.”Rudolf Stark, director of ZF’s passive safety technology division, said on this occasion.
Here’s how the automotive supplier ZF passive safety systems did new smart seat belt technologywhich allows for a better adaptation of the restraint force of the belt to the body size of the vehicle’s occupants, depending on their size and weight.

ZF: adaptive seat belt tensioner

Thus, ZF offers a new belt tensioner with a multi-level adaptive force limiter (MSLL) that turns it into an intelligent, flexible and controllable safety device. Thanks to several levels, it is able to further vary the restraining force throughout the duration of the crash.
This system allows discreet behavior suitable for people of different heights and weights, and therefore properly control the belt tension. This smart seat belt will help further reduce potential passenger injurieswhich will allow car manufacturers to meet the increased requirements of the Euro NCAP road map by 2030.
ZF is taking this opportunity to reveal its vision for the future of seat belts: to improve the recognition of the people sitting on board the vehicle, and therefore more accurately determine the individual fixation force that will be applied to each belt in the event of a collision, manufacturers will be able to internal cameras to analyze the behavior of the driver and passengers.

External obstacle detection systems will also come in handy to determine the direction of impact and thus better protect passengers depending on their position on board.
