A protocol test has been developed in order to validate child back protection systems, taking into account the
most usual accidents and their consequences and with the aim to design the minimum requirements of the KID-
-SHELL system. Moreover, the protocol should ensure repeatability, reproducibility and guarantee the fulfilment of
specific requirements, for that reason the protection will be in fixed position and its strength will be tested with an
impactor that will always give the same impact force in the same point and the same direction. Two different tests
will be carried out:Firstly, to ensure the force absorption of the protection materials, the protection will be placed on a load cell
surface where an impactor will be dropped on 8 different points (see 2.4. sample preparation). The transmitted force
over the load cell surface will be assessed and the force peaks of each impact will be analyzed in order to determine
the safety level of the protection.
The second test will verify the correct adjustment of the system protection at the children’s bodies and their
correct behavior during an impact. A child dummy, which will be lying face down on the load cell surface with the
KID-SHELL protection placed on its back, will receive 8 impacts on different points and the behavior of the
protector will be analyzed. The same 8 impacts will be given to the dummy without the protector and the response
will be compared.
