(57) A device for activating the manual control in an electri- ;ally controlled window
regulator of the type in which the electric control of the window glass translation
is actuated by a motor operated manually in a suitable manner which controls the translation
of the glass by means of kinematic mechanisms which comprise a worm screw-gear assembly
and in which the worm screw is rotated by the motor through a flexible control and
the gear makes to rotate axially a member which gives rise to the vertical translational
movement of the glass, comprises according to the present invention a sleeve and a
bushing interposed between the gear and the said member and rigidly connected to one
another for rotation, the said member being in constant rigid connection with said
member; in addition, the sleeve is pushed by resilient means into rigid rotational
engagement with the gear; manually controlled crank mechanisms produce the disengagement
of the sleeve from the gear against the action of the resilient means in order to
transmit the rotational movement directly to the said member through the crank mechanism
with the interposition of the sleeve.
