A device for winding up one part of a safety belt for a passenger vehicle, especially a land or air vehicle. The device has a spring biased shaft to which the belt is connected so the belt is normally drawn into a housing. The belt can be pulled from the housing when the belt is to be placed in service. The device includes an arresting mechanism operable to lock the shaft to the housing which is actuated when at least one of a certain speed of rotation or a certain angular acceleration of the shaft is exceeded. The device also includes an inertia operated system sensitive to bodily acceleration of the device in at least one plane for actuating said arresting mechanism. |
