| Zusammenfassung: | A force limiting device for a belt retractor is reversible from a higher restraining force level to a lower restraining force level by means of a reversing means during a force limiting phase, wherein the second restraining force level is largely determined by a performance of at least one force limiting element. The reversing means is arranged so that it accomplishes a significant work share upon reversing which is added to the performance of the force limiting element and thus temporarily increases the restraining force of the force limiting device. In this manner undershooting of the characteristic line of the force limiting device upon reversing to the lower restraining force level is compensated. |
