• Abstract:
  Dynamic HYGE sled tests were conducted to evaluate devices which are designed to reposition the ; shoulder belt to provide for improved fit or comfort. Three different devices, representative of those ; being marketed, were tested using the 3 and 6 year old and the 5th percentile female dummies. The ; FMVSS No. 213, "Child Restraint Systems", test seat and test pulse/velocity were used. Tests ; comparing the use of a belt positioning booster seat with and without one of the devices was also ; conducted. ; - mc values greater than 1000 were observed with the Child-Safer™ and the SafeFit™ devices during all ; tests with the 3 year old dummy, and during 5 of the 6 tests with the 5th percentile female dummy. 3 ms ; chest clip values exceeded 60 g's during 2 of the 3 tests with the Child-Safer™ used on the 6 year old ; dummy. Use of the SafeFit™ device resulted in 1 of2 tests with the 3 year old dummy exceeding 60 g's. ; All tests met the head and knee excursion criterion. The 3 year old in the booster seat/Child-Safer™ ; combination exceeded both the mc and chest injury criterion. Some of the belt fit devices kinematically ; effected the various sized occupants differently - one resulted in more 10rso rotation about the lap belt, ; one tended to delay submarining by the small female dummy until later in the crash event and, under ; certain test conditions, all devices contributed to the dummy's torso "rolling-out" of the shoulder belt.
