After the device is integrally arranged on a target seat which needs static evaluation and is set to be solid, the evaluation work of whether the internal structure of the vehicle interferes with the riding space of a dummy or not, whether the dummy is regulated to be in a normal riding posture or not and the like can be carried out according to the definition of relevant regulations;

evaluating whether there is any contact of the structure in the vehicle with the dummy head or leg by observing the contour protruding elements such as the posterior cranial crown short rod 11;

if necessary, the static evaluation can be performed by supporting and fixing the five-point seat belt or the three-point body belt to the whole device through the chest periphery upper cross beam 214, the sternum middle rod 211, the abdomen middle rod 212, the hip intersecting block 34 and other elements, so as to perform related static evaluation work on the action of the restraint system on the aspect of the belt.

To sum up, the utility model discloses a be equipped with adjustable mechanism 23 between thorax bearing structure 21 and back bearing structure 22, can adjust thorax bearing structure 21 and back bearing structure 22 at the fore-and-aft direction of dummy and/or the ascending relative distance in upper and lower direction to simulate the chest structure 2 of different sizes and angle. The thoracic support structure 21 thus formed has an extremely high posture adjustability in forward and backward, upward and downward, pitching flexibility, thereby improving the versatility of the dummy.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
