Belt Force LimiterThe belt force limiter reduces the force of the seat belt on the vehicle occupants above a certain threshold and, in conjunction with belt tensioners and airbags, lessens the risk of upper body injuries being caused to front passengers. In order to achieve this, a torsion bar in the belt retractor distorts. The system then releases the belt at a predefined force level. The maximum shoulder belt force is thus reduced and the occupants are intercepted more gently by belt and airbag. |
