Evaluation of Devices to Improve Shoulder Belt Fit

摘要

Dynamic HYGE sled tests were conducted to evaluate devices which are designed toreposition 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. HIC values greater than 100 were observed with the Child-Safer(TM) and the SafeFit(TM) 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 3 year old dummy exceeding 60 g's.
