Abstract
The research of AIS1 neck injuries has focused on rear-end
collisions, but a great portion of these injuries occur in frontal
impacts. AIS1 neck injuries in frontal impacts can be associated
with seat belt use and it can be hypothesized that the seat belt
may transfer injurious loads to the neck.
This study investigates the influence of the restraint system on
the neck loads by using mechanical as well as mathematical (MADYMO)
models of the HIII 50th percentile dummy. The mathematical
simulations were based on 168 frontal crash pulses collected from
crash recorders, installed in passenger cars in Sweden. The neck
loads were evaluated by a new neck injury criterion NIC
protraction, the upper neck flexion moment and the Nij
criterion.
It was found that a pretensioner, a load limiter or an airbag
have the potential to reduce the neck loads below recently
suggested reference values for long-term neck injuries only as well
as short- plus long-term neck injuries. Moreover, the interaction
between the pretensioner, the load limiter and the airbag was of
great importance in order to minimize the neck loads.
