ABSTRACT:
A motor-vehicle latch assembly has a door latch displaceable between a locked and unlocked position, a housing forming a seat, a lever pivoted on the housing, and a linkage connected between the lever and the door latch for displacement of the latch between its positions by the lever. A lock cylinder can fit in the seat and with the lever and interengaging formations on the lever, housing, and cylinder retain the lever in a predetermined angular position on the housing except when the cylinder is fitted in the seat. The housing is centered on an axis and has an elastically deformable and axially rearwardly projecting tongue having a radially inwardly directed ramp surface. The lever projects radially from the housing and is formed with a radially outwardly open notch receiving the tongue in a predetermined angular position of the lever on the housing. The lock cylinder engages the ramp surface when fitted fully in the seat to deflect the tongue radially outward out of the notch so that until the cylinder is fitted to the seat the lever is prevented from rotating.
