Latch for a vehicle door
First Claim
1. A latch for a vehicle door comprising:
- a first portion arranged substantially parallel to a shut face plane of the latch;
a second portion arranged substantially parallel to an inside face plane of the latch;
a power release mechanism to release the latch, wherein said power release mechanism is provided in said second portion;
an intermediate release lever, said power release mechanism driving said intermediate release lever; and
an inside release lever pivotably mounted co-axially with said intermediate release lever.

Abstract
A latch of a vehicle door includes a retention plate having a shut face portion and a perpendicular inside face portion. The latch further includes a rotatable claw, a pawl resiliently biased into contact with the claw, and an intermediate release lever. The intermediate release lever has an axis of rotation substantially perpendicular to the axes of rotation of the claw and the pawl. During power release of the latch, a controller signals a power release actuator to rotate the intermediate release lever. The power release actuator is positioned in the plane of the inner face portion of the retention plate. As the intermediate release lever rotates, the cam surface of the intermediate release lever operatively rotates the pawl to disengage the claw and release the striker. If there is a failure of the power release mechanism, the mechanical linkage from the inside or outside door handle can be used to rotate the intermediate release lever and release the claw.

15. A latch for a vehicle door comprising:
-
a first portion arranged substantially parallel to a shut face plane of the latch;
a second portion arranged substantially parallel to an inside face plane of the latch;
a power release mechanism to release a latch bolt, and said power release mechanism is provided in said second portion;
an intermediate release lever pivotable about an intermediate release lever axis that is substantially parallel to said shut face plane and driven by said power release mechanism;
a pawl lifter pivotable about a pawl lifter axis that is substantially parallel to said inside face plane, and said intermediate release lever rotates said pawl lifter as said intermediate release lever is driven by said power release mechanism;
a pawl mounted co-axially with said pawl lifter, and said pawl lifter rotates said pawl as said intermediate release lever rotates said pawl lifter;
said latch bolt pivotally mounted about a latch bolt axis that is substantially parallel to said inside face plane, and said pawl rotates to release said latch bolt when said pawl lifter rotates said pawl; and
an inside release lever co-axially mounted with said intermediate release lever to manually release the latch. - View Dependent Claims (16, 17)
