Abstract A window regulator mechanism adapted to lower or raise a window panel into and out of a window well between vehicle body panels, the window panel being divided into separate vertically movable ventilation and visibility sections. With the window panel in raised condition, the mechanism first may be actuated to lower the ventilation section into the window well to provide a ventilation exhaust opening in the vehicle body and then, if desired, further actuated to lower the visibility section into the window well. From a lowered condition, the sequence of movements to raise the panel sections is reversed. Movement of the panel sections is controlled by a pair of regulator arms, one of which is swingable about a pivot axis on the window regulator mounting plate and is connected to the visibility section and the other of which is swingable about a pivot axis on the plate mounted arm and is connected to the ventilation section. A drive means couples the gear sector to the ventilation section arm to translate rotation of the gear sector in window panel lowering or raising direction into panel section lowering or raising movements of the regulator arms. A cam follower means coupled to the ventilation section arm and engaged with cam slot means mounted on a body panel controls the sequence of movements of both regulator arms and thereby the sequence of movements of the window panel sections.
A window regulator mechanism adapted to lower or raise a window panel into or out of a window well between vehicle body panels, the window panel being divided into separate vertically movable ventilation and visibility sections, the window regulator mechanism comprising: a mounting plate secured to one of the body panels, a gear sector rotatably mounted on a pivot shaft journalled in the mounting plate, a first regulator arm swingable about one of its ends on the gear sector shaft and coupled at its other end by a roller and channel connecting means to the visibility section, a pivot member journalled on the first regulator arm intermediate the ends of the latter, a second regulator arm pivotally mounted at one end on the pivot member and coupled at its other end by a roller and channel connecting means to the ventilation section, drive means coupling the Gear sector to the second regulator arm for driving the latter and the first regulator arm in window lowering or raising directions upon movement of the gear sector in window lowering or raising directions, and cam follower means engaged with cam slot means, the cam follower means being coupled to the second regulator arm and being movable in the cam slot means to control the sequence of movements of both the first and second regulator arms.

Claim 3
Dependent Claim
78 words
A window regulator mechanism according to claim 1, in which: the drive means comprises a drive arm fixed to the gear sector for swinging movement about the gear sector pivot axis, and the drive arm is connected to the second regulator arm by a drive link whereby rotary movement of the gear sector in window panel lowering or raising direction is translated into lowering or raising movement of the second regulator arm and thereby the first regulator arm.
Claim 4
Dependent Claim
42 words
A window regulator mechanism according to claim 1, in which: the second regulator arm has a short arm that extends radially from the pivot member and carries the follower means, and the cam slot means is mounted on the one body panel.
