摘要： A vehicle hood latch and method of unlatching a vehicle hood is provided. The vehicle hood latch includes a housing; a ratchet pivotally mounted on the housing; a pawl pivotally mounted on the housing and biased into engagement with the ratchet; a pin fixed for conjoint movement with the pawl; a double pull lever operably mounted to the housing and having an abutment surface configured for operable engagement with the pin, and a primary safety catch lever operably mounted to the housing. The primary safety catch lever is configured to pivot from a locked first position to an unlocked second position. The primary safety catch lever moves from the first locked position to the second unlocked position in response to translational movement of the double pull lever caused by engagement of the pin with the abutment surface of the double pull lever.

摘要： A power latch assembly for a motor vehicle closure system configured to provide a power cinching feature and a power release feature. The power cinching feature is configured to retain the ratchet in a cinched striker capture position with the pawl disengaged from the ratchet. The power release feature is configured to move the ratchet from its cinched striker capture position to a cinch release striker capture position for unloading the seals prior to release of the ratchet to its striker release position.

摘要： A method of making an electrical latch assembly for a door of a vehicle. The method includes providing an electrical housing having a fluid-tight open interior and an opening. The method also includes positioning a printed circuit board in the fluid-tight open interior, wherein the printed circuit board has an electrical control unit. The method further includes connecting a latch mechanism to the electrical housing about the opening, the latch mechanism including an electric motor. The method also includes extending an electrical connector from the printed circuit board, through the opening of the latch mechanism and to the electrical motor to establish an electrical connection between the printed circuit board and the electric motor.

摘要： A closure latch for a vehicle door is provided. The closure latch includes an emergency lock actuator to permit a person to lock the door in the event that the power lock actuator is unusable. The latch also includes an ‘impatient passenger’ feature, which permits the doors to be unlocked using the remote keyless-entry feature on the key fob even in a situation where an ‘impatient passenger’ had prematurely lifted the door handle of the vehicle. In some prior art latches, such an action by an ‘impatient passenger’ would prevent the drive motor on the latch from unlocking the latch, thereby necessitating the owner to press the unlock button on the key fob a second time. There is some overlap in the components that used for the ‘impatient passenger’ feature and the components used for the emergency lock actuator, thereby reducing cost and complexity of the latch.

摘要： A latch release backup system for a latch assembly of a motor-vehicle door is provided with a key cylinder configured to receive a vehicle key and which is rotatably mounted to the motor-vehicle door, and a mechanical coupling arrangement mounted within the motor-vehicle door and operable to convert a rotation of the key cylinder into actuation of an actuation group of the latch assembly for causing latch release. The key cylinder defines an electrical interface socket designed to receive the vehicle key. An electronic control unit is mounted within the motor-vehicle door and is electrically connected to the electrical interface socket to receive identification information (Id) from the vehicle key when plugged into the electrical interface socket. The mechanical coupling arrangement is normally disengaged from the actuation group of the latch assembly, and the electronic control unit is configured to control selective engagement of the mechanical coupling arrangement to the actuation group of the latch assembly based on the identification information (Id) received from the vehicle key.

摘要： A release cable assembly having a release cable and an inertial locking device is provided. The release cable includes a cable wire configured to operably interconnect a release handle to a moveable latch release component of a latch assembly. The inertial locking device is configured to normally permit translational movement of the cable wire, via actuation of the release handle, to move the latch release component from a latched position to an unlatched position when the inertial locking device is exposed to an acceleration that is less than a predetermined acceleration threshold. When the inertial locking device is exposed to an acceleration exceeding the predetermined acceleration threshold, the inertial locking device prevents translational movement of the release cable, thereby preventing unintentional movement of the latch release component from the latched position to the unlatched position.

摘要： A low release effort eccentric double ratchet, double pawl vehicle latch includes a ratchet, a primary pawl, an auxiliary ratchet and a secondary pawl. A drive mechanism including a gear cam wheel sequences movement of the secondary pawl to open and reset the latch. Upon reset, the drive mechanism actuates the auxiliary ratchet back to a closed state in a soft manner without using a hard stop; instead the latch has a cushioning spring that is used to softly stop the gear train during the reset absorbing motor energy and thus eliminating impact noise.
