Abstract

A power tailgate mounting system for a vehicle includes a first gusset member and a second gusset member. The first gusset member is secured to an inward side of a roof rail of the vehicle at a rear end portion of the roof rail. The first gusset member has a first gusset tailgate motor mounting portion extending laterally inwardly from the roof rail for mounting an associated tailgate motor. The second gusset member is secured to the inward side of the roof rail at the rear end portion of the roof rail. The second gusset member has a second gusset tailgate mounting portion extending laterally inwardly from the roof rail for mounting the associated tailgate motor. The second gusset tailgate mounting portion overlaps the first gusset tailgate mounting portion.

Claims

1. A power tailgate mounting system for a vehicle, comprising:

a first gusset member secured to an inward side of a roof rail of the vehicle at a rear end portion of the roof rail, the first gusset member having a first gusset tailgate motor mounting portion extending laterally inwardly from the roof rail for mounting an associated tailgate motor; and

a second gusset member secured to the inward side of the roof rail at the rear end portion of the roof rail, the second gusset member having a second gusset tailgate motor mounting portion extending laterally inwardly from the roof rail for mounting the associated tailgate motor, the second gusset tailgate motor mounting portion overlapping the first gusset tailgate motor mounting portion.

2. The power tailgate mounting system of claim 1 wherein the first gusset member includes a first gusset roof rail portion extending vertically along the inward side of the roof rail, and wherein the second gusset member includes a second gusset roof rail portion extending vertically along the inward side of the roof rail, the first and second gusset roof rail portion spaced apart from one another along a longitudinal length of the roof rail.

3. The power tailgate mounting system of claim 2 wherein the first gusset tailgate motor mounting portion includes a first gusset distal mounting portion spaced apart laterally from the roof rail and defining a first gusset aperture for mounting the associated tailgate motor, and wherein the second gusset tailgate motor mounting portion includes a second gusset distal mounting portion spaced apart laterally from the roof rail and defining a second gusset aperture for mounting the associated tailgate motor, the second gusset distal mounting portion overlapping the first gusset distal mounting portion.

4. The power tailgate mounting system of claim 3 wherein a plane of each of the first and second gusset apertures is arranged generally parallel to the inward side of the roof rail and spaced apart from the inward side of the roof rail.

5. The power tailgate mounting system of claim 3 wherein the second gusset tailgate motor mounting portion includes a second gusset lower flange that overlaps and is secured to a first gusset lower flange of the first gusset tailgate mounting portion, the second gusset lower flange and the first gusset lower flange oriented generally orthogonally relative to the inward side of the roof rail.

6. The power tailgate mounting system of claim 2 wherein the roof rail defines at least one airbag mounting aperture for mounting an associated side airbag and said at least one airbag mounting aperture is disposed between and spaced apart from both the first gusset roof rail portion and the second gusset roof rail portion.

7. The power tailgate mounting system of claim 1 further including:

an external reinforcement member secured to an outward side of the roof rail at locations directly opposite to where the first and second gusset members are secured to the inward side of the roof rail.

8. The power tailgate mounting system of claim 7 wherein the external reinforcement member includes:

a first flange portion overlapping the outward side of the roof rail at the location directly opposite to where the first gusset member is secured to the inward side of the roof rail; and

a second flange portion overlapping the outward side of the roof rail at the location directly opposite to where the second gusset member is secured to the inward side of the roof rail.

9. The power tailgate mounting system of claim 8 wherein the external reinforcement member further includes:

a first wall extending from the first flange portion and generally oriented orthogonally relative to the outward side of the roof rail and the first flange portion;

a second wall extending from the second flange portion and generally oriented orthogonally relative to the outward side of the roof rail and the second flange portion; and

a connecting wall extending between the first wall and the second wall, the connecting wall generally parallel to the outward side of the roof rail and spaced apart from the outward side of the roof rail.

10. The power tailgate mounting system of claim 9 wherein the connecting wall includes an aperture to expose at least one airbag mounting aperture defined in the roof rail for mounting an associated side airbag adjacent the inward side of the roof rail.

11. The power tailgate mounting system of claim 1 further including:

an upper reinforcement member secured to each of the first and second gusset tailgate motor mounting portions at locations on the first and second gusset tailgate motor mounting portions that are spaced apart from one another along a longitudinal length of the roof rail.

12. The power tailgate mounting system of claim 11 wherein:

the first gusset tailgate motor mounting portion includes a first gusset upper flange to which the upper reinforcement member overlaps and is secured; and

the second gusset tailgate motor mounting portion includes a second gusset upper flange to which the upper reinforcement member overlaps and is secured.

13. The power tailgate mounting system of claim 12 wherein the first gusset upper flange defines a clip aperture for mounting an associated wire harness clip at a location spaced inwardly relative to the roof rail and forwardly relative to a terminal rearward end of the roof rail.

14. The power tailgate mounting system of claim 12 wherein:

the second gusset tailgate motor mounting portion includes a second gusset lower flange spaced apart vertically below the second gusset upper flange;

the first gusset tailgate motor mounting portion includes a first gusset lower flange spaced apart vertically below the first gusset lower flange; and

the second gusset lower flange overlaps and is secured to the first gusset lower flange.

15. The power tailgate mounting system of claim 12 wherein the roof rail includes a roof rail upper flange extending angularly relative to the inward side of the roof rail, the roof rail upper flange overlapping and being secured to an inward edge portion of the reinforcement member, the reinforcement member extending inwardly in a generally orthogonal orientation relative to the inward side of the roof rail.

16. The power tailgate mounting system of claim 12 wherein the reinforcement member extends rearwardly from the first gusset member and has a rearward portion secured to a corner structure at which the roof rail terminates, the first and second gusset members spaced apart forwardly along the roof rail relative to the corner structure.

17. The power tailgate mounting system of claim 1:

wherein the roof rail is a side roof rail;

wherein the first gusset member is fixedly secured to the side roof rail adjacent and spaced forwardly relative to a terminal end of the side roof rail; and

and wherein the second gusset member is fixedly secured to the side roof rail adjacent and spaced forwardly relative to the terminal end of the side roof rail, the second gusset member secured to side roof rail at a second gusset location spaced apart rearwardly relative to a first gusset location at which the first gusset member is secured to the side roof rail.

18. The cantilevered motor mounting system of claim 17 further including:

an outward reinforcement member secured to the side roof rail at a location opposite that at which the first and second gusset members are fixedly secured to the side roof rail; and

an upper reinforcement member overlapping and being secured to the first and second gusset tailgate motor mounting portions along upper flanges thereof.

19. The cantilevered motor mounting system of claim 17 wherein the second gusset tailgate mounting portion overlaps the first gusset tailgate mounting portion to provide a reinforced structure to which the vehicle tailgate motor is mounted.
