Abstract
In a passive safety belt system for a motor vehicle, the belt is moved away from the body of the user when the corresponding vehicle door is opened. A master piston-and-cylinder unit is connected between the door and the vehicle body so as to respond to opening and closing movements of the door. Slave piston-and-cylinder units having a smaller bore and larger stroke than the master piston-and-cylinder unit, are connected to the master piston-and-cylinder unit so that a relatively short displacement of the piston of the latter causes a longer displacement of the piston of the former. Each slave piston-and-cylinder unit connected to the safety belt adjacent to a respective anchorage and arranged to displace the safety belt forwardly away from the seat as the door is opened.
