Return mechanism for double pull door latch

1. A latch for a vehicle door, comprising:

a final lever coupled to rotate about a pivot;

a position wheel rotationally coupled to the pivot, the position wheel having a first notch and a second notch, the position wheel being rotatable in a first direction;

a release lever coupled to the position wheel to rotate about the pivot, the release lever being configured to be coupled with a door handle of the vehicle door;

a cam member coupled to the position wheel, the cam member having a cam surface;

a drive lever arranged to engage the first notch and the second notch, the drive lever being pivotally coupled to the release lever; and

a biasing member arranged to apply a force on the cam surface to move the position wheel in the first direction when the drive lever is moved into the second notch, wherein the release lever is configured to move the position wheel from the first position to the second position based on the door handle being pulled a first time and wherein the position wheel is configured to rotate the final lever to a released position based on the door handle being pulled a second time after being pulled the first time.

2. The return mechanism of claim 1 , wherein the biasing member and the cam member cooperate to rotate the position wheel to engage the drive lever in the first notch when the door handle is not pulled for the second time within a predetermined period of time after the door handle being pulled the first time.

3. The return mechanism of claim 2 , wherein the biasing member is a torsion spring.

4. The return mechanism of claim 3 , wherein the final lever includes an arm configured to move a pawl when the door handle is pulled the second time within the predetermined period of time.

5. A method of resetting a double pull vehicle latch, comprising:

rotating a position wheel in a first direction from a first position to a second position based upon a door handle being pulled a first time, the door handle being operably coupled to a release lever operably coupled to the position wheel;

engaging a drive lever in a first notch of the position wheel when the position wheel is in the second position;

rotating the position wheel from the second position to the first position when the door handle is not pulled a second time within a predetermined period of time;

moving the drive lever into a second notch of the position wheel when the position wheel is in the second position; and

rotating a final lever with the position wheel by moving the position wheel into to a third position from the second position when the door handle is pulled a second time within the predetermined period of time.

6. The method of claim 5 , wherein the rotating of the position wheel from the second position to the first position includes applying a force on a cam surface with a biasing member.

7. The method of claim 5 further comprising: engaging a pawl with an arm of the final lever based on the position wheel moving to the third position.

8. A double-pull door latch system, comprising:

a door handle;

a latch operably coupled to the door handle via the release lever rotating about a pivot;

a position wheel operably coupled to the release lever to rotate about the pivot, the position wheel having a first notch and a second notch, the release lever and position wheel cooperating to rotate the position wheel in a first direction from a first position to a second position based on the door handle being pulled a first time, the release lever and the position wheel further cooperating to rotate the position wheel from the second position to a released position based on the door handle being pulled a second time within a predetermined time period after the door handle is pulled the first time;

a drive lever rotationally coupled to the release lever, the drive lever engaging the first notch when the position wheel is in the first position and wherein the drive lever engages the second notch when the position wheel is in the second position;

a cam member coupled to the position wheel; and

a biasing member, the biasing member cooperating with the cam member to rotate the position wheel from the second position to the first position based on the door handle not being pulled a second time within the predetermined time period after the door handle is pulled the first time.

9. The double-pull door latch system of claim 8 further comprising:

a final lever selectively coupled to rotate about the pivot, the final lever rotating with the position wheel as the position wheel rotates from the second position to the released position when door handle has been pulled the second time after the first time within the predetermined time period.

10. The double-pull door latch system of claim 9 further comprising:

a pawl movable from an initial position to an unlatched position;

wherein the final lever engages the pawl to move the pawl from the initial position to the unlatched position when the door handle is pulled the second time after the first time within the predetermined time period.

11. The double-pull door latch system of claim 9 , wherein the drive lever is biased into the first notch in the first position.

12. The double-pull door latch system of claim 11 , wherein the drive lever is biased into the second notch in the second position.

13. The double-pull door latch system of claim 12 , wherein the drive lever engages the second notch when the position wheel rotates to the released position.

14. The double-pull door latch system of claim 13 , wherein the drive lever engages an outer diameter of the position wheel when the position wheel is rotated from the second position to the first position.
