Abstract

A window regulator mechanism for raising and lowering a window pane of a motor vehicle having a door inner panel, which window regulator mechanism has an operating mechanism including first and second regulator arms pivotally connected to each other, the first regulator arm having one end connected to the window pane and the other end connected to actuating means, the second regulator arm having one end connected to the window pane and the other end carrying thereon a roller, and a guide rail for receiving the roller carried on the other end of the second regulator arm. The guide rail is integrally incorporated with the door inner panel and has formed at both ends thereof enlarged portions to receive the roller of the second regulator arm.

Claims

1. A window regulator mechanism for raising and lowering a window pane in a motor vehicle door body having an inner panel, comprising a first arm secured at its one end to a gear segment meshing with a pinion gear mounted on said door inner panel and connected at its other end to said window pane, a second regulator arm pivotally connected to said first regulator arm by a pin at a point spaced apart from said gear segment and connected at its one end to said window pane, said second regulator arm being provided with a roller having an annular enlarged portion thereof at the other end of said regulator arm, said enlarged portion having an annular cylindrical surface thereon, and a guide rail being formed integrally with said door inner panel and including a pair of opposing stepped portions, said stepped portions having opposite parallelly extending plane surfaces thereof for rollably securely receiving therebetween the annular cylindrical surface of the enlarged portion of said roller to guide the other end of said second regulator arm.

2. A window regulator mechanism as claimed in claim 1, wherein said guide rail has formed at one end an enlarged portion.

3. A window regulator mechanism as claimed in claim 1, wherein said guide rail has formed at both ends enlarged portions.

4. A window regulator mechanism as claimed in claim 1, wherein the length of said stepped portions is determined to allow said roller to move from one extreme position to another extreme position thereof during raising and lowering of the window pane.

5. A window regulator mechanism as claimed in claim 2, wherein said enlarged portion is sized to allow ready insertion of an enlarged portion of a roller mounted at the other end of said second regulator arm.
