Facts from real life accidents, where the car was
equipped with a black box (crash recorder), has crea-
ted the background for how whiplash protection sys-
tems can be evaluated in crash tests. So far, the main
efforts within the car to minimise whiplash injuries
in rear end impacts, has been concentrated to the car
seat. Therefore, the tests have been conducted with
the car seats on a sled, with a dummy specialised for
whiplash tests (BioRID 2).
Euro NCAP, the European crash test co-operation is
developing a method to test how car seats protect
from whiplash injuries. This round of tests is perfor-
med following the proposed procedures as of sum-
mer 2006. Euro NCAP is developing their procedures
learning from these tests. The tests are performed in
co-operation with Thatcham in the United Kingdom.
Thatcham also performed the testing.
Three crash tests were performed at different impact
severity levels in order to give a robust validation
of the protective performance of each seat (16 km/
h/4.5g, 16 km/h/5,5g and 24 km/h/6.5g). In each test,
the dummy readings in seven different aspects were
used for the validation. Each aspect is related to th-
ree different phases of the dummy movement in the
crash. In general, the crash tests show that there is a
large variation between the protective performances
of each seat. There are seats that expose the occupant
for a high risk in several of the aspects that were
measured. Other seats demonstrate a high level of
protection. We recommend cars where the rating is
in the “green group”.
The mass of a specific vehicle influence the risk for
whiplash injury in a rear end collision. The risk is
higher in a light weight car compared t
