Etude du comportement du bassin soumis à un chocs latéral

XXIIIeme congrès de la société de biomécanique, VILLEURBANNE, FRANCE, 17-/09/1998 - 18/09/1998Les accidents du trafic routier sont dans 20% des cas des chocs latéraux et l'accidentologie révèle que, pour l'occupant situé du coté de l'intrusion, les lésions du bassin osseux sont significativement plus fréquentes qu'en choc frontal. La question se posait de savoir quelles étaient les influences relatives de la masse et de la vitesse de la surface impactante sur les critères biomécaniques utilisés pour évaluer la sévérité d'un choc

Pelvis human response to lateral impact

16th International Technical Conference on the Enhanced Safety of Vehicles, WINDSOR, CANADA, 31-/05/1998 - 04/06/1998This paper gives a further approach to provide information on the human pelvis tolerance against lateral impacts with unembalmed cadavers. The aim of this work was to verify the influence of impactor parameters as velocity and weight on the criteria measured on pelvis as force, acceleration and deflection. A previous study, presented in 1994 at the ESV Conference, concerned the establishment of behaviour laws for the pelvis response by a 23.4 kg impactor. The analysis of crash tests showed that the impacting masses are lower and the impact velocities are higher. It was essential to know the pelvis behaviour in new impact conditions. A series of 11 new tests were conducted with a guided horizontal impactor at several speeds. The impactor was flat and rigid. It weight was 12 kg or 16 kg. From the 31 tests it is possible to propose a deflection limit value of 46 mm at a 50% AIS 2 2 probability We propose 2 'force / deflection' corridors for impacts energies of 800 and 1100 joules. From these study results we propose : A EUROSID-1 pelvis performance criteria of 3.93 kN with a 50% AIS 2 2 probability. A EUROSID-I pelvis performance criteria of 6.16 kN for a 50% AIS L 3 probability
