There were four objectives in the study: evaluation of belt positioning booster seat protection in crash environments, evaluation of belt positioning booster seat protection if used improperly, evaluation of any significant differences between use and non-use of locking clips on lap/shoulder belts with non-locking latch plates, and evaluation of small shield booster seat protection when used with three point and lap only belts. These objectives were achieved by conducting modified FMVSS No. 213 booster seat tests using 3 and 6 year old dummies. None of the belt positioning boosters seats exceeded the FMVSS No. 213 criteria when used with three point belts. The belt positioning booster seats exceeded one or more of the criteria when used with lap only belts. The use or non-use of a locking clip on three point belts with non-locking latch plates does not appear to have a distinctive influence on dummy responses. One of the 3 year old dummy tests performed without the locking clip exceeded the chest injury criterion. For the small shield booster seat tests, one of the 6 year old dummy tests exceeded the head excursion limit when used with a lap only belt and all of the 3 year old dummy tests exceeded the Head Injury Criterion when tested with a three point belt. Most small shield booster seat instruction manuals state that the shoulder belt should be placed behind the child's back.
