1. A method for dynamically securing an occupant strapped into a vehicle seat of a vehicle with a seat belt, the method comprising:
storing a plurality of situation-dependent triggering thresholds for increasing a belt force acting on the seat belt;
predicting a lateral acceleration to be expected in a course of a bend ahead of the vehicle based on image data of a vehicle environment acquired by at least one camera on the vehicle or based on acquired data of a navigation map;
determining a current driving speed of the vehicle;
selecting, based on a current situation of the vehicle and the current driving speed of the vehicle, one of the plurality of situation-dependent triggering thresholds, wherein the current situation is at least one of a driving mode set for the vehicle, a time of day or ambient brightness, a detected local accident frequency, and determined information from traffic signs; and
increasing, responsive to the predicted lateral acceleration exceeding the selected one of the plurality of situation-dependent triggering thresholds, the belt force acting on the seat belt before the predicted lateral acceleration acts on the occupant,
wherein the current situation further comprises at least one of detected signals from a rain sensor and a temperature outside of the vehicle.
