Vehicle door latch apparatus

Lock mechanism is provided between pawl lever and manual release mean. The present vehicle door latch apparatus includes ratchet member that engages latch and that can be released from latch by release component force F2, latch restraint that prevents ratchet member from being disengaged from latch and powered release means that moves ratchet restraint. Ratchet member includes base lever and pawl lever. When ratchet restraint is moved, base lever is moved to a non-regulated position, where pawl lever can be disengaged from latch by release component force F2. Manual release means is connected to pawl lever. Lock mechanism is provided between pawl lever and manual release means.

Method for controlling a locking element of a vehicle
11518341 · 2022-12-06 · ·

A method for controlling at least one locking element of a vehicle is disclosed. A mobile identification transmitter is detected at a position in a certain access region around the vehicle. Furthermore, a user signal is output to a user carrying the mobile identification transmitter after the mobile identification transmitter has stayed at the position for a first predetermined duration. In addition, the at least one locking element is unlocked/opened after the mobile identification transmitter further stays at the position for a second predetermined duration after the user signal is output. For the targeted control of the automatic unlocking or opening of the vehicle door, the process of unlocking or opening is terminated if a termination signal from the user is detected within the second predetermined duration.

CLOSURE LATCH ASSEMBLY EQUIPPED WITH A POWER CINCH MECHANISM HAVING A CINCH PAWL
20220381072 · 2022-12-01 ·

A latch assembly for a vehicle includes a latch housing, a ratchet, a main pawl, and a cinch mechanism including a cinch pawl and a cinch link lever. When the ratchet moves to a secondary striker capture position, the cinch pawl moves into a blocking position to hold the ratchet. The cinch pawl is actuatable by a cinch lever to move the ratchet to a cinched striker capture position and the main pawl to ratchet checking position. The cinch pawl may be blocked by a stop feature formed in the latch housing in the secondary striker capture position, which resists an opening force exerted on the ratchet. The cinch pawl may be coupled to the cinch link lever, and the cinch link lever may pivot about the same post as the ratchet designed to resist high loads.
