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.

Latch for a vehicle door

A latch arrangement including a latch bolt having at least an open and closed position for releasably retaining a striker in use, the latch bolt being releasably held in at least a closed position by a pawl, the pawl being operably connected to an actuator by a transmission path, such that powered actuation of the actuator causes the pawl to release the latch bolt for opening, the latch arrangement further including means operable to return the actuator to a rest position, independent of movement of the pawl, wherein there is a lost motion connection in the transmission path to provide for the return of the actuator to the rest position independent of movement of the pawl, the lost motion connection being in the form of an abutment on a nut in lost motion connection with a further abutment of the transmission path.
