Project: Evaluation of Child Dummies

Reference: S0014/VF

Last update: 20/08/2003 14:59:28


The project objectives are to:

* assess the sensitivity of the Q3 dummy (Q series for 3-year-old child) response to changes in impact conditions;
* assess the dummy characteristics when placed in different qualities of child restraint systems, and subjected to different severities of crash pulses;
* comparison of the performance of the Q3 dummy with the Hybrid III and P3 dummies, under the same input conditions;
* assess the ability of the Q3 dummy to distinguish between good, medium and poor protection provided by child restraints, in a side impact; and
* assess the suitability of the Q3 dummy for testing airbags.


In Europe child safety restraints are evaluated by means of a range of child crash-test dummies, developed in the 1970's, called the 'P series'. In the UK these dummies superseded a very simple BSI impact test dummy, which consisted of blocks of wood onto which were attached tubular rubber arms and legs. When the European Regulation was being developed (which was later to become ECE Regulation 44) the 'P series' dummies were the most sophisticated dummies available. Even so, they were very simple and could at best be described as 'restraint loading devices'. The knowledge of restraints has developed in the intervening years and these dummies are becoming increasingly inadequate. A more advanced range of child dummies is now available and results from this research programme should enable the DETR to make appropriate recommendations as to their suitability for Regulatory purposes. It shall also provide the necessary background to recommend, support or reject their use in future upgrades to ECE Regulation 44.

Summary of results

  1. The project set out to assess the available child dummies against a new design and, as such, achieved the objectives. Due to the problems identified with the new Q3 dummy during this work it has not been possible to offer definitive results. However, the work carried out will not need to be repeated once further development of the dummy has taken place.
