Task
Shortly before an impact, the seat belt tensioners eliminate seat belt slack and prevent the seat belt's film reel effect. The close-fitting seat belt means that vehicle occupants are subjected to the deceleration forces acting on the body at an earlier stage.
The seat belt is tightened either using the seat belt retractor or simultaneously using the seat belt buckle and the seat belt end fitting.
The seat belt force of the front seat belt tensioners can be adapted accordingly via the seat belt force limiters.
The Supplemental Restraint System (SRS) control unit actuates the seat belt tensioner squibs and seat belt force limiters directly.
