Abstract
Device for tensioning safety belts in vehicles in which one end of the safety belt is securable to the vehicle and the other end of the belt is securable to the tensioning device. The device includes a cylinder having a piston with a piston rod extending from one side of the piston out of the cylinder to which the safety belt is securable. The piston is provided with a recess receiving an electrically ignitable propellant charge cartridge such that upon ignition of the cartridge propellant gases are generated which flow into the cylinder at the piston rod side of the piston for causing the piston and piston rod to be displaced into the cylinder to effect a tensioning of the safety belt.
