Abstract
A power latch assembly and system therewith configured for retaining a closure panel of a motor vehicle in a closed position relative to a vehicle body and for releasing the closure panel to allow the closure panel to be moved from the closed position to an open position. The power latch assembly has a double lock/child lock state, whereat actuation of an inside release mechanism does not release the closure panel for movement to the open position, and whereat actuation of an outside release mechanism permits release of the closure panel for movement to the open position.
Claims20
A power latch assembly for a motor vehicle, comprising:
- a power release actuator arranged to move a power release gear from a home position to a release position to move a pawl from a ratchet holding position to a ratchet releasing position and to cause a ratchet to move from a striker capture position, whereat the ratchet is in latched engagement with a striker to maintain a closure panel in a closed position, to a striker releasing position out of latched engagement from the striker to allow the closure panel to be moved from the closed position to the open position, the power release actuator further arranged to move the power release gear from the home position to a lock position;
- and
- an outside door release mechanism arranged to mechanically move the pawl from the ratchet holding position to the ratchet releasing position while the power release gear is in the home position, the outside door release mechanism being operable to mechanically move the pawl from the ratchet holding position to the ratchet releasing position while the power release gear is in the lock position.
A method of mechanically moving a power latch assembly for a motor vehicle from a latched state to an unlatched state to allow a closure panel to be moved from a closed position to an open position, comprising:
- arranging a power release actuator to move a power release gear from a home position to a release position to move a pawl from a ratchet holding position, whereat a ratchet is in latched engagement with a striker in a striker capture position to maintain the closure panel in a closed position, to a ratchet releasing position, whereat the ratchet moves from the striker capture position to a striker releasing position out of latched engagement from the striker to allow the closure panel to be moved from the closed position to the open position;
- arranging the power release actuator to move the power release gear from the home position to a lock position;
- arranging an outside door release mechanism to mechanically move the pawl from the ratchet holding position to the ratchet releasing position while the power release gear is in the home position;
- and
- arranging the outside door release mechanism to mechanically move the pawl from the ratchet holding position to the ratchet releasing position while the power release gear is in the lock position.
