Zusammenfassung:	The present inventions relates to a control method for an electric seatbelt retractor comprising a spindle (2) and a seatbelt (3) wound thereon, and an electric motor (4) driving the spindle (2) via a rotor (3) in pull-in or in pull-out direction when activated, and a sensor device (10) detecting the movement of the spindle (2), wherein a spring (11) is provided, which is arranged between the spindle (2) and the rotor (3) enabling a relative movement of the spindle (2) to the rotor (3) or to a retractor-fixed part, wherein the electric motor (4) is controlled by a signal of the sensor device (10) generated by the relative movement of the spindle (2) to the rotor (3) or a retractor-fixed part with tensioning or expanding the spring (11).
