6. The window regulator rail assembly as claimed in claim 1 wherein the second fastening portion includes an engagement portion for a tool, the engagement portion being located at an end of the second fastening portion facing away from the attachment collar.

7. The window regulator rail assembly as claimed in claim 6 wherein the engagement portion has one of a square and hexagon shape.

8. The window regulator rail assembly as claimed in claim 1 wherein the attachment collar has a circular outer contour.

9. The window regulator rail assembly as claimed in claim 8 wherein the attachment collar is bevelled towards the second fastening portion.

10. The window regulator rail assembly as claimed in claim 1 wherein the second fastening portion is a second threaded bolt with said fastener screwed onto the second threaded bolt, and with the first fastening portion, the second fastening portion and the attachment collar being integrally formed together as a single-piece component.

11. The window regulator rail assembly as claimed in claim 1 wherein the mounting portion transitions into a bent-edge portion and wherein the nut is non-rotatably held against the bent edge portion.

12. The window regulator rail assembly as claimed in claim 1 wherein the threaded bolt with the mounting portion is directly clamped between the first nut and the attachment collar and the mounting lug is directly clamped between the attachment collar and the fastener.

13. A window regulator rail assembly for a motor vehicle comprising:

a window regulator rail including a mounting portion having a non-threaded elongated hole, a fastening bolt including an attachment collar, a first fastening portion arranged on one side of the attachment collar and a second fastening portion arranged on a side of the attachment collar opposite said first fastening portion, wherein the fastening bolt is releasably and adjustably attached to the mounting portion of the window regulator rail by the first fastening portion, and wherein the second fastening portion includes a fastener that is arranged in a mounting position, and wherein the first fastening portion comprises a first threaded bolt portion extending through the elongated hole and a nut screwed onto the first threaded bolt portion, the nut being non-rotatably held at the mounting portion; and

a mounting lug adapted for mounting on the motor vehicle, the mounting lug including an elongated slot and a generally circular indentation, the elongated slot terminating at one end thereof generally at a center of the indentation, the second fastening portion extending through the elongated slot.

14. The window regulator rail assembly as claimed in claim 13 wherein the indentation that at least partly receives the attachment collar, and wherein the mounting has a first surface facing the first fastening portion and a second surface facing the second fastening portion, the indentation being formed within the first surface to have a generally flat recessed base and a circumferential beveled side wall transitioning from the flat recessed base to the first surface.

15. The window regulator rail assembly as claimed in claim 14 wherein the attachment collar includes a beveled surface cooperating with the circumferential beveled side wall of the indentation to locate the fastening bolt within the mounting lug.

16. The window regulator rail assembly as claimed in claim 13 wherein the attachment collar is selectively movable relative to the mounting portion to adjust a position of the window regulator rail relative to said mounting lug such that when the rail assembly is in a final installed condition, the attachment collar is clamped directly against the mounting portion by the nut and the attachment collar is clamped directly against the mounting lug by the fastener.

17. The window regulator rail assembly as claimed in claim 16 wherein the slot has a width that is greater than a diameter of the second fastening portion.

18. The window regulator rail assembly as claimed in claim 13 wherein a width of the elongated hole is greater than a diameter of the first.

19. A window regulator rail assembly for a motor vehicle comprising:

a window regulator rail including a mounting portion, and a fastening bolt including an attachment collar, a first fastening portion arranged on one side of the attachment collar and a second fastening portion arranged on a side of the attachment collar opposite said first fastening portion, wherein the fastening bolt is releasably and adjustably attached to the mounting portion of the window regulator rail by the first fastening portion, and wherein the second fastening portion includes a fastener and is arranged in a mounting position;

wherein the first fastening portion is a threaded bolt with a nut screwed onto the threaded bolt, and wherein the mounting portion transitions into a bent-edge portion and wherein the nut is non-rotatably held against the bent edge portion, and wherein the attachment collar is selectively movable relative to the mounting portion to adjust a position of the window regulator rail relative to a mounting lug; and

said mounting lug adapted for mounting on the motor vehicle, the mounting lug including a positioning configuration that defines the mounting position of the second fastening portion and wherein the mounting lug includes a slot through which the second fastening portion extends such that when in a final installed condition the attachment collar is clamped directly against the mounting portion by the nut and the attachment collar is clamped directly against the mounting lug by the fastener.
