Referring now to the drawings, the window regulator
mechanism comprises a pair of mounting plates 10 and
7-8.‘ _.At one end the arm 86 includes a pin 88 movable

A second pivot connection is indicated generally at

certain features of it are equally applicable for use in
power window regulators.

mounting ?anges 14 and 16 and ‘an intermediate offset 60

As best seen in FIGURE 2, the pivot mounting means
referred to comprises a pin 24 extending through the 65 arm 98. It will thus be seen that swinging movement of
the arm 86, as occasioned by movement of the actuat
opening 22 having a ?ange 26 bearing against the annular
