ABSTRACT:
In a safety belt system with a belt takeup pulley and a belt runner in which the belt is threaded, the runner has a cross-bar marking the ends, joined together, of the lengths of belt stretched across the user's hips and (slopingly) across his chest. In order to make certain that there is no chance of the size of two such belt lengths being changed by chance while driving or, more specially, stopping any such change in lengths taking place on a smash-up, the belt runner has a part acting as a locking member in the form of a guidepiece having two eyes placed on the two sides of the cross-bar of the runner and having the belt threaded through them. After pulling the belt tight, it is stopped from being moved by the guidepiece, the belt being gripped upon over its full breadth. Furthermore, the guidepiece, in the case of a preferred working example of the invention, has a reinforcement facing the belt having the function of a fulcrum as a guidepiece on the one hand and on the other acting as a further gripping jaw. The guidepiece also has a projection extending across the width thereof which engages the runner to limit the relative movement of the guidepiece and the runner. As part of a specially preferred form of the invention, the guidepiece has a handle making it possible for the guidepiece to be turned in relation to the cross-bar so that, after putting on the belt, the lengths of the parts of the belt running across the hips and chest may be changed.
