Abstract

A vehicle seat belt system, in particular a three-point seat belt system, has belt webbing and an end fitting by which an end of the belt webbing is secured to a vehicle. A belt tensioner acts with a pulling eyebolt through which the belt webbing is guided by a webbing guide in the vicinity of the end fitting to transmit a tensioning movement to the belt webbing. The pulling eyebolt has a substantially straight pulling rod by which a pulling movement generated by the tensioning drive is transmitted to the belt webbing during tensioning and during tensioning the pulling rod acts as a webbing deflection rod for the belt webbing guided through the webbing guide. The webbing guide has two deflection points about which the belt webbing is guided during tensioning and the pulling rod acts on a section of the belt webbing guided between these two deflection points.
