The present invention relates to a belt retractor comprising a belt shaft which is rotatably mounted in a housing and onto which a safety belt can be wound, the housing being able to be fastened to the vehicle, and an electric motor for driving the belt shaft to move rotationally, and a gear mechanism transmitting the rotational movement from the electric motor to the belt shaft, wherein the gear mechanism can be driven as an assembly in a first force-transmission path to drive the belt shaft with a first torque, and the gear mechanism can be driven to drive the belt shaft with a second torque, by shifting a speed-controlled and/or torque-controlled coupling, whereby a second force-transmission path is opened, wherein the coupling has at least one coupling element which is spring-loaded by a spring into engagement in a first part of the gear mechanism.
