assessment of rear-seat safety proposed in this
study. The total injury risk ranged from 36% to near
certainty, indicating significant room for
improvement in the design of rear seats.
However, matching the safety of front seats in the
rear seats is not as simple as replicating front seat
protections in rear seats; features such as airbags
cannot be installed for rear seats the same way as for
front seats, and there are additional considerations
such as size constraints or ensuring the seats are also
safe for children.
To create a safer rear seat, it is important to
understand the nature of injuries in the rear seats. For
example, adults are more often unbelted in the rear
seats, which greatly increases injury rates. Moreover,
when belted, the thorax is the most common
seriously injured body region, followed by the
abdomen. For both of these regions, injuries are
primarily due to interaction with the belt.
Experimental and computational studies have shown
that pretensioners and load limiters, uncommon in rear
seats, but common in the front seats, could decrease
the risk and severity of thoracic injury in the rear seats.
Typical experimental and computational approaches to
studying injury risk in the rear seats involve either a
simplified seat or a single seat from a commercial
vehicle. These prior studies have focused on modifying
the restraint system, such as airbags and seat belts, or
modifying seat parameters such as the pan/back
angles or stiffness.
The numerical methodology developed in this
study provided a reasonable ranking of rear-seat
safety. Therefore, parametric seat models, like those
used in this study, could be used in the future in
various design of experiments (DOE) and
optimization. n
