Abstract

L'invention concerne une ceinture de sécurité pour un véhicule, comportant : - une sangle de ceinture présentant un espace intérieur de ceinture pouvant être soumis à l'action d'un gaz, - une boucle de ceinture et - un pêne de verrouillage pourvu d'un évidement à travers lequel la sangle de ceinture est guidée et au moyen duquel la sangle de ceinture est déviée au niveau d'un point de déviation inférieur lorsque le pêne de verrouillage est introduit dans la boucle de ceinture et lorsque la ceinture est mise, dans une zone de transition, d'une zone de ceinture pelvienne vers une zone de ceinture d'épaule. Selon l'invention, un segment prédéfini de l'espace intérieur de la sangle de ceinture et/ou un canal à gaz (1) disposé dans la zone du point de déviation inférieur, présentent, à l'intérieur, des espaceurs (2) disposés à des intervalles irréguliers dans la sangle de ceinture et/ou dans le canal à gaz (1) de telle manière que des parois opposées de la sangle de ceinture et/ou du canal à gaz sont mutuellement espacées au moins par endroits.
