A latch assembly for a vehicular latching system configured to provide an anti-chucking locking function in cooperation with a latch mechanism. The latch mechanism has a ratchet that is moveable by a striker between a striker release position, a striker capture position, and a striker over-travel position. A pawl is operable in a ratchet holding position to hold the ratchet when the ratchet is in the striker capture position and operable in a ratchet releasing position to release the ratchet to allow the ratchet to return to its striker release position. A latch release mechanism operates to move the pawl between its ratchet holding and ratchet releasing positions. The anti-chuck locking function is provided by the pawl having a lock tooth and the ratchet having a lock notch for locking engagement therebetween when the pawl holds the ratchet in its striker capture position for muting vibrations of the latch assembly.

Vehicular latch assembly with latch mechanism having self-locking ratchet

A latch ( ) having a housing ( ) to which a ratchet ( ) is pivotably mounted by a rivet ( ) for rotation about a first axis between a latched and unlatched configuration. A slot ( ) extents through the latch and has a first arcuate portion ( ) and a first radial portion ( ). A pawl assembly ( ) has a roller ( ) extending through the slot ( ). The pawl assembly is mounted to the housing for movement of the roller relative to the ratchet ( ) between a first arcuate portion and a first radial portion of the slot. The rivet ( ) is deformable to allow the ratchet ( ) to rotate about the roller axis upon the ratchet ( ) being exposed to an unlatching force above a predetermined level. A flange ( ) extends from the housing across the ratchet ( ) to limit the pivotal movement of the ratchet ( ) about the roller axis.

Two stage crush zone latch

An attachment clip ( ) for a vehicle door latch assembly includes a first clip portion ( ) with a first alignment member ( ), a second clip portion ( ) with a first alignment channel ( ), and a resilient hinge ( ) extending between the clip portions so as to allow the clip portions to close around an attachment member ( ). The resilient hinge includes an alignment boss ( ) integrally molded on the hinge and being disposed for engagement with one of the clip portions for forcing engagement upon closing of the clip portions.
