Abstract
A seat-belt retractor comprising a seat-belt spindle, on which a seat-belt can be wound and which is rotatably mounted in a housing that can be fixedly secured to the vehicle, an electric motor for driving the seat-belt spindle in a rotational motion, and a gear mechanism that transmits the rotational motion from the electric motor to the seat-belt spindle, where a first blocking device is provided, which, when activated, blocks at least one of the parts of the gear mechanism, thereby activating the gear mechanism; and the first blocking device can be activated by a signal-controlled actuator, the actuator, in a second function, activating a second blocking device when a pre-defined feed-out acceleration of the seat-belt, or a pre-defined vehicle deceleration is exceeded.
