摘要：Motorized actuator for vehicle door locks e.g. as part of a central lockingsystem has a powered drive input element (20), a drive output element (24) movement ofwhich locks and unlocks the lock, and a clutch element (34) operating to transmit drive tothe output element but having a disengaged condition permitting independent (e.g.manual) actuation of the lock. A camming formation (28) of the input element has aformation (34) of the clutch element coacting therewith and the clutch element hasanother camming formation (36) engaging another coacting formation (38) of the outputelement. The formations are provided with acting faces (32, 44,46) angles so that driveforce applied from the input element through the clutch element to move the outputelement against reaction loading of the latter acts to urge the clutch and output

elements into positive drive transmitting engagement but reaction foces translated fromthe output element with no drive force from the input element releases the clutchengagement by camming the latter formations out of drive transmitting engagementautomatically to put the mechanism into the disengaged condition. Preferably poweredmovement of the input element with the mechanism in the latter condition further shiftsthe clutch element into a superlocked condition in which the output element is positivelyretained in that condition.
