  • Patent number: 11980697
    Abstract: A latch and lock assembly includes a lever pivotable between a latched and unlatched position. A first actuator selectively moves a locking tab between a locked and unlocked position. In the locked position, the locking tab blocks pivotable movement of the lever from the latched position to the unlatched position. In the unlocked position, the locking tab allows pivotable movement of the lever from the latched position to the unlatched position. A second actuator selectively rotates a door opening tab between a first and second position when the locking tab is in the unlocked position is included. When the door opening tab is in the first position the lever is in a latched position, and when the door opening tab is rotated from the first position to the second position, the door opening tab abuts the lever and urges the lever from the latched position to the unlatched position.
