Kraftbegrenzungsvorrichtung, insbesondere für ein Gurtstraffersystem, mit einer Kolben-Zylinder-Einheit (12) mit einem Energiewandler in Form einer Kolben-Sperrvorrichtung (14) und einem beweglichen Schlitten (28) mit zwei gegenüberliegenden Seiten, der mit einer Umlenkung (32) für das Gurtband (34) versehen ist und der auf einer Seite mit der Kolben-Zylinder-Einheit (12) verbunden ist, dadurch gekennzeichnet, daß zusätzlich zu der Kolben-Sperrvorrichtung (14) wenigstens ein weiterer Energiewandler (40; 140; 240) vorgesehen ist, der auf der gegenüberliegenden Seite des Schlittens (28) mit diesem verbunden ist und daß die Energiewandler (14, 40; 140; 240) ihrer Wirkung nach in Reihe geschaltet sind.1. force limiting device, in particular for a belt tensioner system, with a piston-cylinder unit ( 12 ) with an energy converter in the form of a piston locking device ( 14 ) and a movable carriage ( 28 ) with two opposite sides, which is provided with a deflection ( 32 ) is provided for the belt webbing ( 34 ) and is connected on one side to the piston-cylinder unit ( 12 ), characterized in that in addition to the piston locking device ( 14 ) at least one further energy converter ( 40 ; 140 ; 240 ) is provided, which is connected to the opposite side of the carriage ( 28 ) and that the energy converters ( 14 , 40 ; 140 ; 240 ) are connected in series according to their effect. 2. Kraftbegrenzungsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der zweite Energiewandler (40) im Gurtband (34) integriert ist.2. Force limiting device according to claim 1, characterized in that the second energy converter ( 40 ) is integrated in the belt strap ( 34 ). 3. Kraftbegrenzungsvorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß der zweite Energiewandler (40) durch Reißnähte (42) im Gurtband (34) gebildet ist.3. Force limiting device according to claim 2, characterized in that the second energy converter ( 40 ) is formed by tear seams ( 42 ) in the webbing ( 34 ). 4. Kraftbegrenzungsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Kraftbegrenzungsvorrichtung (100; 200) ein Gehäuse (36) besitzt und daß der zweite Energiewandler (140, 240) in diesem Gehäuse angeordnet ist. 4. Force limiting device according to claim 1, characterized in that the force limiting device ( 100 ; 200 ) has a housing ( 36 ) and that the second energy converter ( 140 , 240 ) is arranged in this housing. 5.
