Recent accident research studies. confirm on larger samples the specific vulnerable points of children:
- at the neck level for the youngest,
- at the abdominal level for those who, below age 10-12, use the adult seat belt.
Technical solutions are available : "rearward-facing " seats for the youngest, and boosters cushions above age 3 or 4. Dynamic test procedures encounter serious limitations due to dummy shortcomings and the scant data available to determine protection criteria.
A considerable research is needed, including research on lateral impacts.
