This invention relates to door fastening devices and in
particular to motor vehicle door fastening devices.
On a motor vehicle door there is provided latch means
ment of the contactor from its fastening position to its
releasing position.
The invention will now be described by way of example
with reference to the accompanying drawings, in which:
FIGURE 1 is a side elevation of an operating mecha—
nism of a ‘door fastening device for a motor vehicle door
embodying the invention, and
FIGURE 2 is an end elevation of the mechanism of
FIGURE 1.
Referring now to the drawings, the operating mecha
means on the door is operated from release means which 15

means so that the door may be opened. This operating 20 which is pivotally mounted on the lower part at 15. A

operating mechanism for interposition in a door fasten 30 also urges the contactor as a whole to a fastening posi
ing device between latch means of the device and manu
ally operable release means for the latch means, whereby
the above disadvantage is overcome.
According to the invention, mechanism for interposi
tion in a door fastening device between latch means of the
device and manually operable release means for the latch
means includes actuating means for the latch means; a
two-part contactor for operation by the release means to
operate the actuating means and movable between ‘a
fastening position and a releasing position, a ?rst part
of the contactor being mounted on the second part there
of for movement relative thereto between ?rst and second
tion shown in FlGURE 1 and in which a lug 21 on the
part 12 engages a lug 22 on the backplate.
The upper part 14 has a projection 23 which, when
the upper part 14 is in its ?rst position, coacts with a
stop 2% on the backplate to prevent the contactor as a
whole from substantial pivotal movement about the pivot
axis 13 of the lower part 12. If, however, the upper
part 14- is pivoted clockwise about its pivot 15 to its sec
ond position, the projection 23 is moved downwardly
clear of the stop 24. When the upper part 14 is in its
second position, complementary engaging means consti
tuted by the lug 21 and a portion 25 of the part 14 come
into engagement so that further movement of the upper
