Children under six years of age who are prematurely restrained in adult seat belts are at more than 3 times increased risk of injury as compared with children in child restraint systems (CRS). As a result, CRS (child safety seats and booster seats) are recommended as appropriate restraints for young children and use of different types of child restraints is increasing rapidly. The objective of this study was to begin to evaluate the performance of multiple restraints at a range of speeds, utilizing the Hybrid III 3- and 6-year-old child dummies. Injury measurements were compared for a 3-year old restrained in a forward facing convertible child restraint, a backless belt-positioning booster seat and in a lap shoulder seat belt; and, for a 6-year old restrained in a backless belt-positioning booster seat, a high back belt-positioning booster seat, and a lap shoulder seat belt. A matrix of tests (total of 18) at speeds of 24, 40, and 56 kph were used in the evaluation.
