In a method for operating a belt retractor, the belt retractor comprising a belt tensioner drive and with a pre-tensioner drive which can both exert a torque onto a belt spool in a direction for winding a safety belt, the pre-tensioner drive is prevented from exerting a torque onto the belt spool through the activation of the belt tensioner drive. In a belt retractor for a safety belt, having a belt spool, a pre-tensioner drive with a drive motor, which can turn the belt spool in the winding direction for the purpose of pre-tensioning the safety belt, and with a belt tensioner drive which can drive the belt spool for the purpose of a belt tensioning, a safety mechanism is provided, which through an activation of the belt tensioner drive prevents the pre-tensioner drive from driving the belt spool in the winding direction.
