Abstract

L’invention se rapporte à une ceinture de sécurité (3) d’un siège (2) de véhicule comprenant une sangle thoracique (9) associée à un premier enrouleur (13), une sangle ventrale (10) associée à un deuxième enrouleur (14) et un pêne (11) séparant ladite sangle thoracique (9) et la sangle ventrale (10) et destinée à venir s’arrimer dans un dispositif de fixation, solidarisé à un élément de structure du véhicule. Selon l’invention, le pêne (11) de ceinture comprend une partie fusible (20) dotée d’un élément d’accrochage (30) auquel est destinée à être relié un airbag (16), le deuxième enrouleur (14) étant doté d’un mécanisme supplémentaire (31) de rétraction comportant un fil (21) passant dans la sangle ventrale (10) et qui est solidarisé à la partie fusible (20), de sorte que dans le cas d’un choc accidentel du véhicule contre un obstacle extérieure la partie fusible (20) se détache du pêne (11) et coulisse le long de la sangle ventrale (10) sous l’effet de la rétraction du fil (21), entrainant le déploiement de l’airbag (16) sous la sangle thoracique (9).
