ABSTRACT:
A locking mechanism for vehicle safety belts of the type in which a strap of the belt is automatically retracted into a housing and coiled up on a reel when the belt is not in use, to lock the reel at rapid extraction of the strap of the belt. The locking mechanism comprises a supporting means which is non-rotatably attached to the reel for rotation with it and which carries at least two latching means pivotably mounted on two pivot pins positioned symmetrically in relation to the reel and parallel with it. At rapid rotation of the reel, the latching means are turned by the centrifugal force about their respective pivot pins from a free position to a latching position with the forward portion in engagement with a stop means. The latching means are arranged to engage with each other in such a way that an angular turn of one latching means causes a corresponding equal large angular turn of the other latching means, so that the latching means are simultaneously turned out-wards into the latching position.
