Child occupant protection in vehicles is a major
issue of concern for parents and the government. This
book is an effort to numerically study the injury
mechanisms incurred by toddlers in a vehicle crash
and further propose methods to mitigate them.
Different countermeasures were investigated to
mitigate the head and neck injury potential in
frontal and side impact crashes. These methods
involved numerical studies utilizing a Hybrid III
3-year-old dummy, Q3/Q3s dummies and a child FE
model. Load limiting behaviour into the upper tether
and lower LATCH anchors of the CRS in order to reduce
the neck injury criteria by increasing forward head
excursion in a frontal crash was first examined.
Secondly, a head and neck restraining device was
developed to limit the amount of neck rotation in the
dummy s head. Finally, numerical simulations were
completed with rectangular and cross-shaped sections
of rigid ISOFIX systems for better side impact
protection. In addition, studies were conducted to
confine lateral movement of the dummy s head by
incorporating energy absorbing foam on the side wings
in the vicinity of the contact region of the CRS.
