a motor operably coupled to the cursor such that operation of the motor will cause the cursor to slide along the guide rail, the motor being mounted to the mounting portion, wherein the motor when mounted to the mounting portion is located adjacent to a side of the guide rail located between the bottom end of the guide rail and the top end of the guide rail and the cursor being capable of sliding along a portion of the guide rail that is adjacent to the arm portion and the mounting portion such that a portion of the cursor can be located between the guide rail and the mounting portion and at least a portion of the arm portion.
2. The window regulator as in claim 1 , further comprising a cable drum rotationally mounted to the flange portion, the cable drum being operably coupled to the motor and at least one cable secured to the cable drum at one end and the cursor at another end.
3. The window regulator as in claim 1 , further comprising a lower pulley rotationally mounted to the rail mounting portion and an upper pulley rotationally secured to secured to the top end of the guide rail by a housing.
4. The window regulator as in claim 1 , wherein the guide rail is a three sided structure with an opening and the guide rail is insert molded onto the flange portion the flange portion has a structural member that extends into the opening.
5. The window regulator as in claim 1 , wherein the guide rail is an extruded structure that has internal structural features that extend across a cavity of the guide rail.
6. The window regulator as in claim 1 , wherein the guide rail has a rectangular periphery and a portion of the cursor completely surrounds the guide rail.
7. The window regulator as in claim 6 , wherein the guide rail is hollow.
8. The window regulator as in claim 6 , wherein the portion of the cursor surrounding the guide rail has multiple contact points with the guide rail in order to prevent twisting of the cursor as the cursor slides up and down the guide rail.
9. The window regulator as in claim 1 , wherein the rail mounting portion, the arm portion extending and the mounting portion are all formed as a single piece.
10. The window regulator as in claim 1 , wherein the motor extends in a direction generally parallel to the guide rail.
11. The window regulator as in claim 1 , wherein a pair of cables are secured to a cable drum rotationally mounted to the flange portion at one end and the cursor at another end.
12. The window regulator as in claim 11 , wherein the flange portion further comprises cable guides configured to guide the pair of cables as they are wound and unwound from the cable drum.
13. The window regulator as in claim 1 , wherein the arm portion extends laterally and upwardly towards the top end of the guide rail from the bottom end of the guide rail.
14. A window regulator for raising and lowering a window of a vehicle, comprising:
a guide rail;
a cursor slidably mounted to the guide rail;
a flange portion only mounted to a top end of the guide rail, by a rail mounting portion of the flange portion, and an arm portion and a mounting portion extend from the rail mounting portion, the mounting portion terminating at a distal end of the mounting portion that is spaced from a bottom end of the guide rail, the arm portion and the mounting portion do not directly contact the guide rail; and
a motor operably coupled to the cursor such that operation of the motor will cause the cursor to slide along the guide rail, the motor being mounted to the mounting portion, wherein the motor when mounted to the mounting portion is located adjacent to a side of the guide rail located between the bottom end of the guide rail and the top end of the guide rail and the cursor being capable of sliding along a portion of the guide rail that is adjacent to the arm portion and the mounting portion such that a portion of the cursor can be located between the guide rail and the mounting portion and at least a portion of the arm portion.
15. A window regulator for raising and lowering a window of a vehicle, comprising:
a guide rail;
a cursor slidably mounted to the guide rail;
a flange portion only mounted to a bottom end of the guide rail, by a rail mounting portion of the flange, and an arm portion and a mounting portion extend from the rail mounting portion, the mounting portion terminating at a distal end of the mounting portion that is spaced from a top end of the guide rail, the arm portion and the mounting portion do not directly contact the guide rail; and
a motor operably coupled to the cursor by at least one cable such that operation of the motor will cause the cursor to slide along the guide rail, the motor being mounted to the mounting portion, wherein the motor when mounted to the mounting portion is located adjacent to a side of the guide rail located between the bottom end of the guide rail and the top end of the guide rail and the cursor being capable of sliding along a portion of the guide rail that is adjacent to the arm portion and the mounting portion such that a portion of the cursor can be located between the guide rail and the mounting portion and at least a portion of the arm portion.
16. The window regulator as in claim 15 , further comprising a lower pulley rotationally mounted to the rail mounting portion and an upper pulley rotationally secured to secured to the top end of the guide rail by a housing.
17. The window regulator as in claim 16 , further comprising a cable drum rotationally mounted to the flange portion, the cable drum being operably coupled to the motor and the at least one cable being wound and unwound from the cable drum as cable drum is rotated by the motor.
18. The window regulator as in claim 17 , wherein the guide rail has a rectangular periphery and a portion of the cursor completely surrounds the guide rail.
19. The window regulator as in claim 18 , wherein the guide rail is hollow.
