    Abstract: A secondary release mechanism for a vehicle hood latch has a pivotally mount ed secondary latch (12) which is rotatable between a latching position and an unlatching position and biased towards the latching position. A pivotally mounted release arm (26) is rotatable between a retracted position, a deploy ed position and a releasing position and biased to the standby position. A pivotally mounted release lever (20) is rotatable between a release position , a standby position and a retract position . The release lever (20) has a cam surface (22) for engaging a hood of the vehicle as the hood moves between th e fully latched condition and a secondary latched condition responsively rotating the release lever (20) between the standby position and the retract position. The release lever (20) operably engages the secondary latch (12) a s the release lever (20) rotates from the standby position to the release position. The release arm (26) engages the release lever (20) wherein responsive movement of the release lever (20) between the standby position t o the retract position responsively effects movement of the release arm (26) between the deployed position and the retracted position and movement of the release arm (26) from the deployed position to the releasing position responsively effects movementof the release lever (20) rotating the secondar y latch (12) from the latching position to the unlatching position.

    Abstract: A latch assembly (10) has a housing having a mouth. A ratchet (12) is pivotally mounted to the housing and is movable to cooperate with the mouth to pivot between an open condition, a primary closed condition and a secondary closed condition for receiving, engaging and cinching a keeper of a striker. The ratchet (12) is biased to the open condition. A pivotally mounted pawl (40) is biased into engagement with the ratchet for releasably retaining the ratchet in the primary closed condition. A secondary release arm (20) is mounted to rotate about a first axis and a second axis. The secondary release arm (20) is rotatable about the first axis between a retracted position and an extended position, and is rotatable out the second axis between an engaging position and a disengaging position. The secondary release arm (20) is biased to the retracted position and biased to the engaging position. The secondary release arm (20) interengages with the ratchet (12) for coupled movement therewith from the primary closed condition to the secondary closed condition effecting movement of the secondary release arm (20) from the retracted position to the extended position upon the pawl (40) being rotated to disengage from the ratchet (12). Upon moving the secondary release arm (20) from the engaging positionto the disengaging position, the secondary release arm (20) disengages from the ratchet (12) for independent movement enabling the ratchet (12) to rotate from the secondary closed condition to the open condition and back to the primary closed condition. The secondary release arm (20) also rotates from the extended position to the retracted position.

    Abstract: A latch assembly (10) has a housing (12) having a mouth (14). A detent fork (16) is pivotally mounted within the housing (12) to cooperate with the mouth (14) to pivot between an open and closed condition for receiving, engaging and cinching a keeper (60) of a striker. The detent fork (16) is biased in the open condition. A pivotally mounted pawl (24) is biased for engagement with a pin (26). Pin (26) is slidably mounted within a guideway (38) and positioned between the detent fork (16) and the pawl (24). The pin (26) cooperates with the pawl (24) to retain the detent fork (16) in the closed condition. The pin (26) rolls between the pawl (24) and detent fork (16) as the pawl (24) is rotated in a releasing sense to disengage the detent fork (16).

    Abstract: A self-releasing clutch assembly for locking a vehicle door lock. The clutch assembly (11) includes a servo-actuated input drive and a cinching output drive. A gear shaped first actuator (42) is mounted to the input drive. A cylindrical second actuator (44) is mounted to the output drive and is moveable relative to the first actuator. Four pairs of rollers (50) are interdisposed between the first and second actuators and moveable between a disengaged position and an engaged position. With the disengaged position, the rollers rest against the first actuator and allowing the second actuator to rotate relative thereto. With the engaged position, the rollers interlock the first and second actuators for relative concurrent movement. The clutch assembly is characterized by the first actuator including four driving surfaces (43) and the second actuator including four corresponding abutments (48). The driving surfaces engage and move the rollers from the disengaged position to the engaged position in response to movement by the input drive. The abutments then lock the rollers between the first and second actuators to couple the input drive with the output drive thereby transferring the movement of the input drive to the output drive. The subject invention also includes a biasing device (54) for automatically returning the rollers to the disengaged position when the driving force from the first actuator ceases.
