Abstract: Motorized actuator for vehicle door locks e.g. as part of a central locking system has a powered drive input element (20), a drive output element (24) movement of which locks and unlocks the lock, and a clutch element (34) operating to transmit drive to the 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 a formation (34) of the clutch element coacting therewith and the clutch element has another camming formation (36) engaging another coacting formation (38) of the output element.

Abstract: Rotating claw or other vehicle door latch assembly has locking mechaism including a crank element (33) rotatable about a first axis (34) between angular positions at which the latch is locked or unlocked, a push-pull linkage (38), e.g. of a door sill button, being connected to a second axis (35) of said element for manual actuation thereof, deadlocking means (31,40) being selectively operable to position the crank element with said axis substantially in line with the direction of movement of the linkage so that the latter cannot be used to effect movement of said element which would unlock the latch.

Abstract: A vehicle door latch of the kind having a latch bolt with a rotating fork or claw which cooperates with a door postmounted striker is provided which comprises two separate pawl plungers which can be independently urged into a coacting relationship with an engaging face of the bolt to retain the bolt at a safety position (at which the door is near closed) and at a fully latched position (at which the door shut). Both plungers can be withdrawn electrically and/or manually to free the bolt for opening the door.
