“…It defines a simple and robust tool allowing the investigation of various restraint systems and the deformations undergone in automobile crashes by a human being (figure 7). The human body model is able to reproduce submarining (Leung et al, 1982), i.e. the slip of the pelvic belt above the iliac crests (figure 8).…”

This article presents a finite element human body model, used in the Laboratoire d'Accidentologie, de Biomécanique et d'études du comportement humain of French car manufacturers for its occupant safety research programs. The working-out, the main construction steps of and the validation process are described. An example of application, which consists of a comparative study in frontal crash with a dummy model, illustrates the interest and limitations, through the most significant results. After a basic study, applied to the development of a new thoracic criterion highlighting real safety, the approach to improve the model into a 3D breakable model is shown. The bone condition differences are taken into account. Several future research prospects are exhibited in order to reinforce the human body model. RÉSUMÉ. Cet article présente un modèle éléments finis de l'être humain, utilisé au laboratoire d'accidentologie, de biomécanique et d'études du comportement humain des constructeurs français pour ses recherches sur la sécurité des occupants de véhicules automobiles. La genèse, les grandes étapes de construction et de validation du modèle sont décrites. Un exemple d'application, qui consiste en une étude comparative du comportement au choc avec un modèle de mannequin de choc frontal, illustre son intérêt et ses limites, avec l'appui des résultats les plus significatifs. Après une étude de principe, appliquée à la définition d'un critère thoracique mettant en valeur la sécurité réelle, la démarche de transformation en un modèle lésionnel omnidirectionnel est montrée, avec la prise en compte des différences interindividuelles. Quelques perspectives de recherches permettant de le consolider sont exposées.

“…The fracture pattern of the ribs is consistent with excessive anterior chest compression on the left side. The Toyota Central R and D Labs Research,[ 10 ] based on computational model, showed lateral rib fracture along the path of the diagonal belt similar to a 30 mph frontal crash scenario. Figure 3 shows the zoomed rib fracture pattern and its location.…”

The purpose of this study and a case report was to demonstrate seat belt webbing induced injury due to seatbelt submarining during the frontal motor vehicle crash. Submarining is an undesired phenomenon during a frontal crash scenario and is dependent on design features of the seat pan and seatbelt system. The lack of adequate anti-submarining features at any seating position with three-point restraint can cause abdominal solid and hollow organ injuries. This paper reports a case of submarining and factors that exacerbated this phenomenon leading to critical occupant abdominal injury. This case report and the following injury causation analysis demonstrate the shortcomings of a cantilever seat pan design in context to the occupant safety. The inadequate seat pan anti-submarining feature in association with lack of seatbelt load-limiter and Pretensioner reduces the level of occupant protection offered by the seat belt system in the rear seat. This case report shows the dangers of cantilever seat pan design and its association with increased risk of submarining causing severe abdominal injuries.
