A three-point safety harness for use in a motor vehicle consists of two safety belts, each having its own individual retractor mechanism, the retractor mechanisms being mounted on the side of the relevant seat which is furthest from the associated door of the vehicle. One safety belt extends to a carriage movable along a rail mounted on the roof of the motor vehicle extending over the door opening. This safety belt is to form a chest strap. The other safety belt extends to a carriage movable along a rail formed in the door of the motor vehicle. This is the lap strap. The two straps are connected together by means of a slidable element which defines a passage or passages through which the safety belts pass in a sliding manner. The safety belt that forms the lap strap has a thickened portion which cannot pass through the said element. The safety harness if of the "passive" kind and the arrangement ensures that the belts are kept free of the seat when the door is open and the person using the harness is getting into or out of the motor vehicle. |
