During the phase IV of the EEC biomechanical programme, the available side impact dummies were evaluated and this work concluded that none of the dummy was acceptable. The European Experimental Vehicle Committee set up a working group to built a new side impact dummy to be used in a standard side impact test. The ONSER laboratory was in charge of the development of the pelvis. This paper includes the specifications for the pelvis, agreed by the EEVC working group dealing with this subject, anthropometric analysis to choose sizes and mass distribution a description of the shape of the pelvic bone and the location and the type of transducer (force, acceleration). The design of the hip joint and the use of deformable materials to simulate the pelvic bone deformations are discussed. Results of impactor tests using a dummy fitted with this pelvis are analyzed and their results compared to those of cadavers tests conducted previously. The results of these first tests seem promising and have be completed especially to validate the repeatability and the durability.
