ABSTRACT:
A device for stepwise pulling in with great force and stowing a belt or strap, comprising a stepwise feeding mechanism which pulls in the strap through a locking means allowing passage of the strap towards the mechanism but locking the movement of the strap in the opposite direction, and a storage or winding-in device for collecting the fed-in strap. The step feeding mechanism comprises two elements, which are pivotable about a common axis, together as well as relatively to each other. The strap passes between the elements which co-act with each other and with the strap so that when they are swung together in one direction they grip and coil the strap while simultaneously pulling in the strap. When the elements are swung back in the opposite direction they move somewhat relatively to each other, thereby releasing the strap. When the elements are swung once again in the first direction they can thus grip a new length of the strap and pull it in a further distance, whereafter the cycle is repeated while generating a large force in the strap.
