In a crash, seat belts have to respond fast, without impacting too heavily on their wearers. The solution is to use pretensioners, which tighten the belts during the very first fractions of a second. Autoliv’s active seat belt goes one step further by using a gentle pre-pretensioner that optimally softens belt impact. Its controllers use AUTOSAR-compliant software.
