First Claim
1. A mechanism adapted for controlling the reciprocating movement of a first planarly slidable window panel and a second planarly slidable window panel with each panel independently slidable between fully raised, lowered and intermediate positions independently of one another within a common sliding plane, said mechanism comprising a first rotatable operating arm and means for changing rotational movement of said arm into reciprocal movement of said first panel, a second rotatable arm and means for changing the rotational movement of said second arm into a reciprocal movement of said second second panel, a common pivotal shaft for both said arms, a sector gear secured to each arm, for causing rotation of the respective rotatable arms on rotation of said sector gears, both said sector gears mounted for rotation independently of one another on said common pivotal shaft, and means for driving each sector gear independently of the other sector gear to reciprocate the windows independently of one another, each said driving means including a pinion gear in mesh with a respective one of said sector gears, and a unitary structural plate for mounting said pinion gears and said common pivotal shaft, and wherein said unitary structural plate is configured to secure said entire mechanism to a flat wall, said plate including a central socket area for said pivotal shaft, said wall and opposed sockets spaced from said shaft for said pinion gear mountings.

Abstract
Disclosed is a regulator mechanism for two window panels mounted in the door of an automotive vehicle. The panels are slidable independently of one another in a common plane between raised and lowered positions under the control of the regulator mechanism. Both window panels are operated by independently operable lever arms, both lever arms being mounted for rotation on a common pivot shaft. The lever arms are secured to respective sector gears, both sector gears also being mounted for rotation on the common pivot shaft. Each sector gear is driven independently of the other by a driving gear, the driving gears being angularly spaced from the pivot shaft to prevent operative interference between the operative end of each lever arm. The mechanism is mounted as a unitary assembly on a unitary mounting plate, the plate providing a support structure for the common pivot shaft and the respective pinion shafts. In this manner, the spacing between the respective operating gears is set once the mechanism is assembled as a unit and need not be adjusted on assembly of the unit into the vehicle.
