Abstract

A center roller assembly for a vehicle slide door includes a support arm having a first end portion hingedly connected to the vehicle slide door and a second end portion. A roller unit includes a load roller rotatably connected to the second end portion by a load roller shaft and first and second guide rollers flanking the load roller and rotatably connected to the second end portion by first and second guide roller shafts. A first drive cable has a first attachment member secured to an end portion thereof and directly connected to the first guide roller shaft. A second drive cable has a second attachment member secured to an end portion thereof and directly connected to the second guide roller shaft. The first and second guide roller shafts are each configured to prevent disengagement of the first and second attachment members from the first and second guide roller shafts.

First claim

The invention claimed is:

1. A center roller assembly for a vehicle slide door comprising:
a support arm having a first end portion hingedly connected to the vehicle slide door and a second end portion;
a roller unit provided at the second end portion of the support arm, the roller unit including a load roller rotatably connected to the second end portion by a load roller shaft and first and second guide rollers flanking the load roller and rotatably connected to the second end portion by respective first and second guide roller shafts;
a first drive cable having a first attachment member secured to an end portion thereof, the first attachment member being directly connected to the first guide roller shaft, the first attachment member including a first part secured to the end portion of the first cable and a second part nonremovably secured to an outer surface of the first part, the first part including a first body having an outer side surface and an inner side surface defining a first opening extending therethough, the first opening dimensioned to slidably receive the first guide roller shaft;
the second part of the first attachment member includes a second body, the second body including:
a first wall,
a second wall spaced from and overlapping the first wall,
a third wall directly connecting the first and second walls, and
a connecting member directly connecting the first and second walls,
wherein when assembled the first and second walls are in direct contact with respective upper and lower outer surfaces of the first body, the third wall is in direct contact with the outer side surface of the first body, and the connecting member is received in the first opening of the first body; and
a second drive cable having a second attachment member secured to an end portion thereof, the second attachment member being directly connected to the second guide roller shaft,
wherein the first and second parts of the first attachment member are configured to prevent disengagement of the first attachment member from the first guide roller shaft.

2. The center roller assembly of claim 1 , wherein the connecting member includes a second opening dimensioned to slidably receive the first guide roller shaft.

3. The center roller assembly of claim 2 , wherein the connecting member including first and second spaced wall sections, each of the first and second wall sections being received in the first opening of the first part and in direct contact with the inner side surface of the first body to further secure the second part to the first part.

4. The center roller assembly of claim 1 , wherein the second attachment member includes a first part secured to the end portion of the second cable and a second part secured to the first part, the first and second parts of the second attachment member being identical to the first and second parts of the first attachment member.

5. The center roller assembly of claim 4 , wherein the first part of each first and second attachment member is generally ring-shaped and the second part of each first and second attachment member is an overmolded second part that is overmolded onto the first part.

6. The center roller assembly of claim 4 , wherein end portions of the first and second guide roller shafts include as least one radially extending projection, and the connecting member of the second part of the first attachment member and a connecting member of the second part of the second attachment member are shaped to at least partially conform to the end portions of the first and second guide roller shafts.

7. The center roller assembly of claim 1 , wherein an end portion of the first drive cable is fixed within the first body of the first part by at least one pin secured in at least one opening located in the first body.

8. The center roller assembly of claim 1 , wherein the second body of the second part is configured to sandwich from above and below a majority of the first body of the first part.

9. A center roller assembly for a vehicle slide door comprising:
a support arm having a first end portion hingedly connected to the vehicle slide door and a second end portion;
a roller unit provided at the second end portion of the support arm, the roller unit including a load roller rotatably connected to the second end portion by a load roller shaft and first and second guide rollers flanking the load roller and rotatably connected to the second end portion by respective first and second guide roller shafts, each of the first and second guide roller shafts including an end portion having a radially extending projection; and
a first drive cable having a first attachment member secured to an end portion thereof, and a second drive cable having a second attachment member secured to an end portion thereof,
wherein the first attachment member includes a first part secured to the end portion of the first cable and an overmolded second part that is overmolded onto an outer surface of the first part so that the second part is nonremovably secured to the first part, the first part includes a first body having a first opening dimensioned to slidably receive the end portion of the first guide roller shaft, and the second part of the first attachment member includes a second body, a portion of the second body received in and at least partially lining the first opening, wherein the portion of the second body is a connecting member including first and second spaced wall sections, and wherein the second body includes a first wall and a second wall spaced from and overlapping the first wall, the connecting member interconnecting the first and second walls.

10. The center roller assembly of claim 9 , wherein the first opening has a keyway for the projection of the first guide roller shaft and the first and second wall sections are configured to flank the keyway.

11. The center roller assembly of claim 9 , wherein edge portions of the respective first and second walls are connected by a third wall directly contacting the outer surface of the first part.

12. The center roller assembly of claim 9 , wherein the second attachment member includes a first part secured to the end portion of the second cable and an overmolded second part that is overmolded onto the first part of the second attachment member, the first and second parts of the second attachment member being identical to the first and second parts of the first attachment member.

13. The center roller assembly of claim 12 , wherein the first and second attachment members are adapted to move axially unrestricted over the respective first and second guide roller shafts in a first orientation of the first and second attachment members relative to axes of the respective first and second guide roller shafts, and
wherein the first and second attachment members are adapted to prevent axial movement off the respective first and second guide roller shafts in a second orientation of the first and second attachment members relative to the axes of the respective first and second guide roller shafts.

14. The center roller assembly of claim 13 , wherein the second orientation is angularly offset from the first orientation.
