Abstract
In a belt tensioner () for a seat belt comprising an elongate pressure reservoir (), a piston () movably supported in the pressure reservoir () in the longitudinal direction to which piston pressurized fluid can be applied and which in this way can be moved in a tensioning direction (S), a mechanical thrust means () interacting with the piston, the thrust means interacting with a gearwheel () and driving the same in the case of restraint, and comprising a stop () on which the piston () abuts in the tensioning direction in a final position, it is provided that between the piston () and the thrust means () a spacer () in the form of a separate member is provided which is dimensioned such that in the final position of the piston () the thrust means () is urged past the stop () by said spacer. Furthermore there is provided a method of mounting a belt tensioner of this type.
