Abstract: A latch described herein comprises a ratchet movable between a primary closed position, a secondary closed position and an open position. The ratchet is biased towards the open position for facilitating travel of a striker in a fishmouth of the latch to the secondary closed position. The latch includes a pawl movable between a primary locking position, a secondary locking position and an unlocking position. The pawl is biased towards the primary locking position and has a pawl locking surface for holding the ratchet in the primary closed position and the secondary closed position. The latch includes a lift lever biased towards the open position for moving the striker in the fishmouth away from the secondary closed position and towards the open position when the pawl is in the unlocking position. The striker is further from the primary position when in the open position compared to the secondary closed position.

Abstract: A closure panel latch assembly can include an overslam bumper mechanism comprising a biasing element as a spring formed from a metallic material positioned relative to a slot of the latch assembly. The biasing element resists entry of a striker into the slot beyond a selected position in order to inhibit contact of the striker with a bottom end of the slot. Also provided is a closure panel latch assembly configured with the biasing element as a resilient element positioned relative to the slot of the latch assembly; The biasing element is coupled to the striker engagement member, such that the striker engagement member is positioned to engage the striker and resist travel of the striker towards the bottom end, wherein the biasing element controls the resistance to movement of the striker engagement member by the striker.

Abstract: A power actuator for automotive door latches. The actuator includes an electric motor mounted in a housing. A worm is operatively coupled to the motor for driving rotation of the worm about an axis. A worm gear, which meshes with the worm, is mounted to a tubular mount in the housing for rotation about an axis substantially orthogonal to the worm axis. A cam mounted to the worm gear engages the lever of a latch. An integral camshaft depends from the cam and extends into a central aperture on the worm gear, making the rotation axis of the two coincident. The distal end of the camshaft includes at least one resilient finger received through the aperture and in abutting contact with an opposing surface of the gear to preclude axial withdrawal of the camshaft from the wheel aperture. The power actuator uses a reduced number of components.
