A belt tensioner () for a seatbelt system comprises a tensioner tube () having an open outlet end and a force transmission element () which is guided in the tensioner tube () and which leaves the tensioner tube () via the open outlet end, a gas generator () providing compressed gas for displacing the force transmission element () within the tensioner tube () as well as a drive wheel () rotated by the force transmission element () leaving the tensioner tube (). There is provided a guiding component () surrounding the drive wheel () into which guiding component the force transmission element () enters upon leaving the tensioner tube (). At the guiding component () an energy-dissipating structure () is provided which the force transmission element () contacts when it has at least substantially completely left the tensioner tube ().
