Just like the active seat-belt buckle recently presented by Mercedes-Benz that is likewise earmarked for inclusion in a luxury model, the Beltbag was

Because dummy measurement technology is not capable of quantifying the benefits resulting from a wider belt strap, such as the lower force exerted on occupants, the safety experts at Mercedes have also been working intensely with virtual human models, as such computer-generated models make it
possible to obtain detailed findings on the biomechanical strain during a
