Safety belt retractor having a locking mechanism which is operatively connected with the spindle of the retractor and comprises a rotor connected with the spindle, and at least one locking element displaceably arranged in the rotor, said locking element being engageable with an associated stationary locking element by a relative rotational movement of the spindle and the rotor for locking the spindle against rotational movement, and a device sensitive to inclination and/or deceleration, which is adjusted, by inclination of the retractor or retardation of a vehicle in which the retractor is mounted, from a disengaged position to an engaged position restraining the rotation of the rotor to provide a relative rotational movement of the spindle and the rotor at initial withdrawal of the belt and thus locking of the spindle in order to prevent continued withdrawal of the belt. The rotor comprises a support mounted for rotation in relation to the spindle and having two radially displaceable locking members mounted therein which are spring biased in order to engage a non-circular portion of the spindle, and a toothed rim to be engaged by said device sensitive to inclination and/or deceleration, is rotatably mounted on the support and is rotatable therewith by way of a resilient drive connection.
