  • Patent number: 8091821
    Abstract: A method for controlling an electric belt retractor (16) which has an electric motor (20) which can drive a belt spool (18) in a belt band retraction direction and/or in a belt band withdrawal direction, and a blocking catch which is able to be guided into blocking teeth in order to block a rotation of the belt spool (18) in the belt band withdrawal direction, comprises the following steps: Operating the electric motor (20) in belt band retraction direction for tensioning the belt band (26); Detecting a possible belt band withdrawal; Determining a stable vehicle state; and Re-operating the electric motor (20) in belt band retraction direction only when a belt band withdrawal is detected.

  • Publication number: 20070057107
    Abstract: A belt retractor includes an electric motor which is able to drive a belt spool at least in the direction of retraction of the belt webbing, and a vehicle-sensitive blocking mechanism having blocking teeth and a locking catch which is able to be guided into blocking teeth, in order to block a rotation of the belt spool in the direction of withdrawal of the belt webbing. A method for controlling the electric belt retractor comprises the following steps: operating the electric motor in the direction of retraction of the belt webbing, to tension the belt webbing, automatic monitoring of specific release criteria to release the belt retractor after the tensioning of the belt band webbing is completed, and initiating a further brief operation of the electric motor in the direction of retraction of the belt webbing, to release the locking catch when the release criteria are fulfilled, the monitoring being continued during the further brief operation of the electric motor.
