This force limiter produces a belt force so that at the maximum requested crash-velocity and each lower one the maximum possible relative forward displacement between passenger and vehicle will be nearly used. Thereby, the passenger loads by the belt will be reduced, as well as the decelerations effecting the passenger, at a lower than the maximum requested crash-velocities in accident statistics, injuries by the belt will be effectly reduced, mainly for people of fragile contitution.The princip of the force limiter is a hydraulic throttling member. Due to the relative speed between the passenger and the vehicle the force limiter produces a belt-force according to its F-vrel.-ratio.PROCEEDING -
