Abstract

[0046] Système de ceinture de sécurité pour véhicules pour la protection d'un occupant dans le véhicule qui comporte une unité mobile montée sur un siège de véhicule. L'unité mobile utilise un actionneur pour déplacer un élément mobile qui est bouclé de manière amovible à une extrémité d'une plaque d'extension. L'autre extrémité de la plaque d'extension est fixée à une boucle utilisée pour fixer de manière amovible une sangle de ceinture de sécurité. Un actionneur ayant un MGG est utilisé pour fournir la force nécessaire afin de déplacer l'unité mobile jusqu'à une position qui aide à retenir en toute sécurité l'occupant lors d'un événement de collision oblique. Selon un mode de réalisation, un élément d'acheminement mobile est utilisé pour déplacer la sangle jusqu'à une position activée pour immobiliser l'occupant. Selon un autre mode de réalisation, une unité d'acheminement dynamique est montée sur une partie arrière supérieure du siège pour immobiliser l'occupant.
