Our group is studying how injuries occur in children when they are involved in crashes, and how changes to the types and design of restraints used by children can reduce serious injuries and death. Key problems include whether children use restraints correctly and whether they use restraints that are appropriate for their size. Recent findings include that rates of misuse of child restraints are high, and much of this misuse is serious enough to compromise the effectiveness of the restraints in crashes. Building on our recent work that led to major changes in child restraint design and usage laws in Australia, Dr Julie Brown and I are currently studying how restraint ergonomics and comfort affect how children use restraints, and whether we can improve how restraints are labelled to help parents to use them correctly.
