The invention relates to a force-limiting device (4) for a seat belt device, which has at least two parts (5, 11, 15) which are controlled relative to each other by a movement defined in a frequency-related manner, wherein the parts (5, 11, 15) moving relative to one another have intermeshing toothings (8, 10, 18, 19) and the movement controlled in a frequency-related manner takes place by the fact that at least one of the parts (5, 11, 15) executes an advancing movement (V) in relation to the other part (5, 11, 15) with an undulating movement (Q) which is directed transversely with respect to the advancing movement (V) and in which the toothings (8, 10, 18, 19) alternately enter into engagement and pass out of engagement, by means of which a force-limited extension of the belt webbing is made possible, wherein means are provided, by means of which the required force for moving the parts (5, 11, 15) with respect to one another is automatically increasable after a predetermined extension length of the belt webbing.
