Abstract
The invention relates to an arrangement for tensioning a seat belt in an automotive vehicle in the event of a collision. The belt extends through a slot in a displaceable and rotatable drum. One end of a tensioning strap is inserted into the slot and connected to a wedge located therein. The other end of the tensioning strap is attached to the chassis of the vehicle. When the drum is rotated, by means of a drive means intended herefor, both the tensioning strap and the belt strap are reeled onto the drum, therewith causing the drum to be displaced downwards while reducing the effective length of the belt strap.
