Abstract

A passive safety belt system for motor vehicles. The upper point of a diagonal-type belt is displaced by a fitting, slidably mounted in a guide track extending above the door between vehicle posts that are forward and rearward of the driver's door and joined to a cord connected with a differential mechanism which has a manual drive and preferably comprises two unequally large sheaves. The cord is reeled up on one sheave when a drive device such as a pull wire is unreeled from the other sheave. The differential mechanism coacts with the door lock so as to release it just before the fitting reaches the forward end of the track.
