Abstract

L'invention concerne un système de fermeture comprenant un mécanisme de blocage (20) servant à fermer une porte de véhicule automobile ou un ouvrant de véhicule automobile, un dispositif d'actionnement (1, 2) servant à ouvrir le mécanisme de blocage (20), un dispositif de verrouillage (18) servant à verrouiller le système de fermeture, un dispositif de sécurité (3, 4) qui peut empêcher une ouverture intempestive du mécanisme de blocage (20) en cas d'accélérations élevées et/ou de vitesses élevées, ainsi qu'une commande (13, 14, 15, 16, 19, 24) servant à activer le dispositif de verrouillage (18) pour verrouiller le système de fermeture en cas d'accélérations élevées et/ou en cas de vitesses élevées. Le système comprend un dispositif de retenue (28, 29, 30) qui est conçu de telle manière que le dispositif de retenue (28, 29, 30) assure que le système de fermeture est verrouillé par le dispositif de verrouillage (18) lorsque le dispositif de verrouillage (18) a été activé par la commande (13, 14, 15, 16, 19, 24). L'invention permet d'obtenir un verrouillage particulièrement fiable du système de fermeture en cas de collision.
