<p>Pivot endstops (17,20) on the twist bolt (2) and locking pawl (7) work with the control disk (13) in the opening and closing stages respectively and have allocated return springs (19,22), using a pin (16) on the disk (13) to trip the respective endstops. An electric motor (10) serving as actuator drives the disk (13) and the twist bolt (2) as reduction gearing. The drive motor (11) trips the endstop (17) for the locking operation, as against endstop (2) of the pawl for the opening operation. The locking pawl (7) should be pre-tensioned pivotally towards the bolt (2) and the control disk (13).</p> |
