Global side door latch
First Claim
1. A latch for an automotive door, comprising:
- a housing;
a ratchet and pawl mounted to the housing, the ratchet and pawl cooperatively operable to move between an engaged position operable to hold a striker and a released position;
a release lever, pivotally mounted to the housing, and having a slot;
a lock link lever, the lock link lever having first and second ends, the first end being operatively coupled to the pawl and the second end being slidably retained in the release lever slota lock lever pivotally mounted to the housing and operable to move between a locked and an unlocked position, the first end of the lock link lever being connected to the lock lever via a lost motion connection and moveable between a biased coupled position, wherein moving the lock lever between the locked and unlocked positions effects a corresponding movement in the lock link lever between its locked and unlocked position, and an uncoupled position, wherein the second end of the of lock link lever is in the locked position and moving the lock lever does not effect corresponding movement of the lock link lever to the unlocked position;
a motor connected to the lock link lever via a gear system so that in response to a first state of an electrical signal the motor operatively decouples the first end of the lock link lever from the pawl and in respond to a second state of the electrical signal the motor does not interfere with the first end of the lock link.

Abstract
The latch includes a ratchet and pawl operable to move between an engaged position to hold a striker and a released position to permit the striker from exiting the latch. In addition, a release lever and a lock lever are pivotally mounted to the opposite surface of the latch housing. A lock link lever connects the release lever to the lock lever, having a first end pivotally mounted to the lock lever and a second end slidably located in a slot on the release lever. Actuating the release lever while the second end of the lock link lever is in its locked position pivots the lock link lever in a first arc and actuating the release lever while the lock link lever is in its unlocked position pivots the lock link lever in a second arc to actuate the pawl into its released position.

25. A latch, comprising:
-
a housing; a ratchet and pawl mounted to the housing, the ratchet and pawl cooperatively operable to move between an engaged position operable to hold a striker and a released position; an outside release lever, pivotally mounted to the housing; a power release actuator operable to release the pawl in response to a state of an electrical signal, the power release actuator including a power release motor, a cam rotatably driven by an output on the power release motor, and a pawl engage lever operatively connected to the cam and extending outwards towards the pawl; the pawl engage lever being pivotally mounted to a set of linkages that is pivotally mounted to the cam, the set of linkages being movable between an engage position where the pawl engage lever abuts against and is operable to actuate the pawl, and a bypass position wherein the pawl engage lever is displaced away from the pawl and so is inoperable to actuate the pawl wherein the set of linkages is further operatively connected to the outside release lever so that moving the outside release lever from its resting position to its actuated position moves the set of linkages to the engage position, and returning the outside release lever to its resting position moves the set of linkages to the bypass position; wherein activating the power release motor translates the position of the pawl engage lever so that the pawl actuates the pawl when the set of linkages is in the engage position, thereby releasing the latch. - View Dependent Claims (26, 27, 28, 29)
