1. A method for dynamically restraining an occupant fastened into a vehicle seat with a seatbelt in a vehicle, wherein a transverse acceleration of the vehicle and a course of a road ahead of the vehicle are determined and the seatbelt is tightened with a predefined belt force a predefined length of time before the vehicle enters a bend that has a predefined curvature, comprising the steps of:
assigning a respective comfort speed to different turning angles of turnoffs and turnings at which it is possible to comfortably drive into the turnoffs or around the turnings; and
when the vehicle nears a turnoff or a turning at a current driving speed that exceeds the comfort speed assigned to the turning angle by a predefined value, the seatbelt is tightened with a predefined belt force before the turnoff or the turning is reached.
