Project: Interior Headform Tests

Reference: S0013/VF

Last update: 20/08/2003 12:40:02

Objectives

The project objectives are to:

* eEnsure practicality of performing the proposed test procedure for the ranges of vehicles for which it is applicable (including completeness, consistency of interpretation, tolerances and complexity of the procedure);
* ensure feasibility of compliance with the proposed test procedure requirements for the category of vehicles for which it is applicable (e.g. validation of proposed performance criteria and field of application);
* validate the repeatability and reproducibility of the test procedure;
* evaluate the sensitivity of the test procedure to different design concepts (e.g. 'good' & 'bad' designs); and
* Examine the compatibility with US Federal and other regulations.

Description

The DfT has actively supported the work programme within the European Enhanced Vehicle Committee (EEVC) to develop an instrumented headform test to assess the probable injury pattern for a human head striking the interior of a vehicle during an accident. This project is to validate the new test procedure to ensure that it reflects true accident conditions. Once agreement has been reached in Europe on the test procedure, it is expected that discussions will be undertaken in order to develop a harmonised world standard for head protection in cars.

Summary of results

  1. The project identified some difficulties in carrying out the proposed type-approval test procedure developed by WG13, but provided practical solutions and amended the test procedure accordingly. Comparison between the proposed WG13 procedure and the existing FMVSS 201 US procedure showed that, while there are many areas in which the two test procedures are compatible, the differing philosophies between the US and European approaches (i.e., self certification Vs third-party Type Approval) means that the selection of the 'worst case' impact points and approach angles can make a critical difference; hence some car interiors which already 'meet' FMVSS 201 would not meet the WG13 procedure.
