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 ().

Tensioning device for seatbelts with an olive-shaped piston

A guide loop for a seat belt in motor vehicles, comprising a one-piece metal body a cladding part and a displacement body. The metal body includes a fixing eye and a belt guidance slit and a rounded running surface. The a cladding part is made of plastic and held onto the metal body, and the displacement body limits the slit height of the belt guidance slit, through which webbing of the seat belt runs. The cladding part is formed as a one piece body with edge areas that at least partially enclose the metal body is firmly secured to the metal body by means of tension applied by the edge areas onto the metal body.
