Abstract
A tensioning device for a seatbelt system in motor vehicles with a driving arrangement that comprises a tube having at least one tube section bent with a radius of curvature, and a piston guided movably in said tube, whereby the piston is connected via a driving cable to the part of the seatbelt system which carries out the tensioning movement, and whereby the piston can be moved in a longitudinal movement through the tube by means of a pyrotechnic drive, and the driving cable is fixed to the piston by means of a holding part held by the piston. The piston () is configured in the form of an olive with a larger radius in the longitudinal direction of the tube () than the effective radius in the transverse direction of the tube () and is provided with a bore () for passing through the driving cable () that is held in a compression sleeve () fixed on the side of the piston () that points in the direction of movement of the piston ().
