Abstract and keywords

Over the years, vehicles have become stiffer and front occupant belt pretensioners and load limiters have become standard, showing great benefit in terms of compartment intrusion and injury values. While vehicle safety for children has also increased, there is limited research showing how, with today's stiffer cars, child safety could be improved by introducing pretensioners and load limiters in the rear seat.

The aim of this study was to evaluate the benefit of pretensioners and load limiters for a HIII 6y seated on three different aftermarket booster cushions (with and without backrest) and on one integrated booster cushion. The results showed that adding a pretensioner and a load limiter to a standard retractor reduced loading of the head, neck and chest for all tested booster cushions. The integrated booster cushion offered the best protection.
