Rebound-Simulation for the Determination of the Necessary Strength of Passenger Seats in Buses 785043
The strength of passenger seats and seat mounts are usually
evaluated on the basis of personal vehicle tests. In particular,
the backrest, its mounting, and the seat mounting are subjected to
horizontal forces and evaluated. None of these tests, however,
accounts directly for forces exerted by unbelted passengers thrown
from behind into the rear of the backrests. The purpose of the
paper was to investigate the validity of the testing procedure for
commercial vehicles. Result were based on deceleration and rebound
tests with dummies.
The tests showed that none of the passenger seats or their
mountings was damaged by the deceleration of its own mass. However,
all test seats were deformed by dummies striking them from behind
under simulated collision conditions. Seat mountings remained
undamage, though. It was concluded that the personal vehicle tests
should not be directly applied to commercial vehicles because the
forces applied on the backrests are not directly comparable in the
two cases.
