Abstract
Abstract A window regulator mechanism, that is a mechanism adapted to raise and lower the window glass of a motor vehicle, is disclosed in which the tension of the cable which physically effects the raising and lowering movements of the window glass can be adjusted by the agency of a sawtooth clutch connecting the cable winding drum and a gear segment mounted coaxially therewith. The adjustment is effected by means of a specially provided torque wrench.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
In a window regulator device, especially for windows of vehicle doors, of the kind having a window-operating cable attached at one end to a winding drum mounted inside a vehicle door on a shaft which drives the drum selectively in opposite directions, and attached at its opposite end to a wheel which is rotatably mounted on said shaft adjacent said drum and is operatively connected by a unidirectional clutch to said drum, the improvement comprising crenellated means on said wheel registering with an opening in one side of said door and engageable by a tool, which is insertable through said opening from outside the door, and which is operable to rotate the wheel relative to the drum.
Claim 2
Dependent Claim
117 words

Claim 3
Dependent Claim
22 words
A device according to claim 1, wherein said means comprises a plurality of teeth formed on the peripheral surface of said wheel.
Claim 4
Dependent Claim
32 words
A device according to claim 2, including a torque wrench having an output shaft insertable through said opening in said door and equipped with a pinion capable of meshing with said teeth.
Claim 5
Dependent Claim
59 words
A device according to claim 1 wherein said unidirectional clutch comprises confronting saw-tooth surfaces formed on said drum and said wheel, respectively, and a leaf spring mounted in a recess in one side of said wheel and engaged with an enlarged-diameter head on one end of said shaft to bias the wheel axially on the shaft toward said drum.
Claim 6
Dependent Claim
35 words
A device according to claim 4, wherein the leaf spring comprises a planar central portion seated against said head, and two arcuate portions projecting from opposite sides of said central portion and against said wheel.
Claim 7
Dependent Claim
39 words
A device according to claim 1, wherein the edge of the drum has thereon a raised, circumferential flange portion confronting said wheel and projecting radially beyond said clutch teeth to prevent snarling of the cable in said clutch teeth.
