The piston having a gas generator with gas vents directed with a component in the opposite direction to that of the piston movement for belt tightening. The piston also having locks and seals, the locks being operable only against the belt loosening direction, and wherein the gas generator is positioned forward of the locking mechanism in the direction of piston movement for belt tightening. A more compact, cost effective pretensioner is possible.
