Abstract
A device for tightening a seat belt has a piston () drivable linearly in a piston guide () by the gas pressure of a propellant gas. A gearing () is also caused to move by the piston (), the gearing serving the transmission of the piston movement to a pinion (). The pinion () is connected to, or configured to be connected to, a belt spool of a seat belt retractor () in a manner whereby rotation of the pinion causes rotation of the belt spool. The gearing () on associated with the piston () is mounted displaceable transversely to the piston's direction of movement and meshes with the pinion () as a result of gas pressure in an expandable bladder ().
