Zusammenfassung:A latch arrangement includes a lever (32) movable in response to movement of a door lever (20,21). A controller is configured for selectively preventing movement of the lever. The controller includes a mono-stable blocking element (46) in the form of a bi-metallic strip or a piezoelectric beam, which can be operated in such a way that its distal end acts to block movement of the lever (32). The controller also includes a bi-stable blocking element (41) which has a nib (43A) that can be moved to an extended position to block movement of the lever (32). Both blocking elements can be operated at the same time. Unlatching of the door is prevented when either of the blocking elements are arranged in the path of the release lever (32).
