حزام أمان مزود بنظام حماية الركاب الاستباقي
PRE-SAFE - is not just a seat belt tensioner
حزام أمان مزود بنظام حماية استباقي
The next step in the development of integrated safety was the anticipatory occupant protection system PRE-SAFE® which Mercedes-Benz introduced in 2002. This active passenger protection system operates on the logical assumption that accidents often follow emergency braking. If PRE-SAFE® detects the signs of a pending accident, the mechanical belt tensioners are pre-tensioned with the help of electric motors before the potential accident occurs.
PRE-SAFE® also moves seats and backrests into a particularly safe position and, in addition, closes the sunroof (provided one is fitted and open). PRE-SAFE® does not just sense emergency brake applications, but also unstable driving situations reported by the ESP® and BAS functions, such as skidding and heavy oversteer or understeer which could cause a rollover. Since its debut in 2002 in the S-Class (W 220 series), PRE-SAFE® has been adopted in other Mercedes-Benz models.
