An integrated vehicle occupant energy management system (10) and method (100) performs front and side impact detection (102), determination of occupant position and type (106), and control of seat belt tension (104 and 108) and deployment of one or more air bags (114) from a single unit (12) positioned at the vehicle's b-pillar. Real time and dynamic management of occupant energy is provided to optimize energy absorption through seat belt tensioning as a first response to a crash situation, and follow-up deployment of one or more air bags as needed.

La présente invention, qui concerne un système intégré (10) de gestion de l'énergie pour les occupants d'un véhicule et le procédé correspondant (100), assure la détection d'impact frontal et latéral, la détermination de la position et du type (106) de l'occupant, la régulation du tensionnement des ceintures de sécurité (104, 108) ainsi que le déploiement d'un ou plusieurs coussins de sécurité gonflables (114) à partir d'un seul module placé sur le pied milieu du pavillon. La gestion dynamique en temps réel de l'énergie des occupants permet d'optimiser l'absorption d'énergie par tensionnement des ceintures de sécurité en tant que première réaction en cas de collision, et permet de provoquer, dans la foulée, le déploiement, suivant les besoins, d'un ou de plusieurs coussins de sécurité gonflables.
