Abstract

A door latch has a main housing holding latching element that can retain it in a latched or an unlatched position. A manual actuating mechanism is movable in the main housing between actuated and unactuated positions and a coupling part on the main housing can move between a coupling position connecting the actuating mechanism to the latching elements for displacement of them into the unlatched position on displacement of the actuating mechanism into the actuated position and a decoupling position for disconnecting the actuating mechanism from the latching elements. A central locking element on the main housing is movable between locked and unlocked positions and a locking mechanism jointly movable with the locking element can displace the coupling part into the decoupling position on displacement of the central locking element into the locked position and for displacing the coupling part into the coupling position on displacement of the central locking element into the unlocked position. One mechanism has an externally accessible actuation formation and an auxiliary housing independent of the main housing holds a linkage having a pair of ends and is secured on the main housing wit…
