Guidelines with regard to the body strength of buses have been
drawn up in Japan. We now pass to the second step in research to
assure the greater safety of bus crews and passengers by launching
a study on further reduction of collision injuries to bus
occupants. As a way to reduce such passenger injuries, our focus is
the optimization of energy absorption, the arrangement of equipment
on the passenger seat back, the seat frame construction, mounting
and so on. The study was conducted using an experimental method
together with FEM computer simulation.
The findings from a sled impact test simulating a seat in a bus
in a frontal collision are stated as follows.
1.Further consideration should be given to the present
conventional ELR two-point seat belt.
2.One way to reduce passenger injury is to optimize the space
between seats.
This report proposes measures to reduce passenger injuries based
on the experimental approach employed and introduces a computer
simulation model and the like now under development.
