First Claim
1. A latch mechanism for a vehicle door, the latch mechanism comprising:
- a latch bolt;
a pawl biased into engagement with the latch bolt to maintain the latch bolt in a latched condition, wherein the pawl has an engaged position where the pawl engages the latch bolt and a disengaged position;
a manual release lever for operable linkage to a vehicle door handle;
a power release member movable to displace the pawl from the engaged position to the disengaged position;
a pawl lifter that shifts the pawl between the engaged position and the disengaged position; and
a clutch member mounted to the pawl lifter and being movable by the manual release lever relative to the pawl between a first rest position at which a break is created in a transmission path from the power release member to the pawl and a second position at which power actuation of the power release member is capable of moving the pawl from the engaged position to the disengaged position.

Abstract
A latch mechanism for a vehicle door includes a latch bolt, a pawl biased into engagement with the latch bolt to maintain the latch bolt in a latched condition, and a manual release lever for operable linkage to a vehicle door handle. A power release member is movable to displace the pawl from an engaged position where the pawl engages the latch bolt to a disengaged position where the pawl does not engage the latch bolt. A clutch member is mounted such that movement of the pawl causes movement of the clutch member. The clutch member is movable by the manual release lever between a first rest position at which a break is created in a transmission path from the power release member to the pawl and a second position at which power actuation of the power release member moves the pawl from the engaged position to the disengaged position.

16. A latch mechanism for a vehicle door, the latch mechanism comprising:
-
a latch bolt; a pawl biased into engagement with the latch bolt to maintain the latch bolt in a latched condition, wherein the pawl has an engaged position where the pawl engages the latch bolt and a disengaged position; a manual release lever for operable linkage to a vehicle door handle; a power release member movable along a path to displace the pawl from the engaged position to the disengaged position; a pawl lifter that shifts the pawl between the engaged position and the disengaged position; and a clutch member mounted to the pawl lifter and being movable by the manual release lever between a first rest position at which a break is created in a transmission path from the power release member to the pawl and a second position at which power actuation of the power release member is capable of moving the pawl from the engaged position to the disengaged position, wherein the transmission path of the power release member remains the same irrespective of a position of the clutch member. - View Dependent Claims (17)
