A safety belt retractor for motor vehicles having a locking system controllable in a belt webbing-sensitive and/or vehicle-sensitive manner, a locking pawl () mounted on the belt shaft () which locking pawl can be moved into engagement with a housing-fixed tooth, wherein the locking system can be deactivated at least within a range of a predetermined belt extraction length, wherein a locking element () is provided for deactivating the locking system which locking element can be moved depending on the belt extraction length from a first position releasing the locking pawl () to a second position fixing the locking pawl ().

Seat belt retractor with deactivatable locking system

A self-locking belt retractor for motor vehicles with a vehicle-sensitive and a belt-webbing-sensitive control system for the blocking arrangement of the belt retractor, is characterized in that for the formation of its inertia, an inertial mass is swivellably mounted on a control disk, wherein the inertial mass can be deflected into a blocking position for the control disc. Additionally, a locking lever mounted on the control disc is provided for the cutoff of a vehicle sensor, and by way of a switching process in its cutoff position, the locking lever cuts off the vehicle sensor and secures the inertial mass in a disabling position, the disabling position being different than the blocking position.
