POWER TAILGATE MOUNTING SYSTEM FOR A VEHICLE
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.
A single drawn sheet metal stamping is conventionally used to reinforce the location at which a power tailgate motor is mounted to the vehicle. While this works in many vehicle configurations, some vehicle package designs have an increased distance between the load point for the power tailgate motor and its attachment to the general body structure. Directional loading on the power tailgate motor under the forced closed loading condition can be severe and can require a very rigid mount for the motor. Use of the conventional reinforcement method could potentially result in deflection of the outer roof panel on the vehicle and is thus unacceptable.
SUMMARYAccording to one aspect, 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.
According to another aspect, a cantilevered motor mounting system for a vehicle tailgate motor includes a side roof rail, a first gusset member, and a second gusset member. 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. 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 is secured to the 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. The first gusset member has a first gusset tailgate motor mounting portion extending laterally inwardly from the side roof rail and the second gusset member has a second gusset tailgate mounting portion extending laterally inwardly from the roof rail.
According to a further aspect, a vehicle mounting system includes a first gusset member and a second gusset member. The first gusset member is fixedly secured to an associated roof rail on a vehicle. 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 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.
Referring now to the drawings wherein the showings are for purposes of illustrating one or more exemplary embodiments and not for purposes of limiting the same,
The first gusset member 14 has a first gusset tailgate motor mounting portion 14a extending laterally inwardly from the roof rail 18 for mounting an associated tailgate motor 20. Likewise, the second gusset member 16 has a second gusset tailgate motor mounting portion 16a extending laterally inwardly from the roof rail 18 for mounting the tailgate motor 20. As will be described in more detail below, the second gusset tailgate motor mounting portion 16a overlaps the first gusset tailgate motor mounting portion 14a to provide a rigid mount for the tailgate motor 20.
In the illustrated embodiment, the roof rail 18 is a side roof rail and the rear end portion 18b of the roof rail 18 is a terminal end or end portion of the roof rail 18. Thus, the first gusset member 14 is fixedly secured to the roof rail 18 adjacent and spaced forwardly relative to the terminal end 18b of the roof rail 18 and the second gusset member 16 is fixedly secured to the roof rail 18 adjacent and spaced forwardly relative to the terminal end 18b of the roof rail 18. As shown, the second gusset member 16 is secured to the roof rail 18 at a second gusset location 22 spaced apart rearwardly relative to a first gusset location 24 at which the first gusset member 14 is secured to the roof rail 18. Thus, the first gusset member 14 is fixedly secured to the roof rail 18 at the location 24 which is forwardly disposed (i.e., relative to a longitudinal direction of the vehicle 12 and of the roof rail 18) relative to the location 22 at which the second gusset member 16 is fixedly secured to the roof rail 18.
More specifically, the first gusset member 14 includes a first gusset roof rail portion 14b extending vertically along the inward side 18a of the roof rail. Likewise, the second gusset member 16 includes a second gusset roof rail portion 16b extending vertically along the inward side 18a of the roof rail 18.

Further, the outward reinforcement member 30 includes a connecting wall 30e extending between the first wall 30c and the second wall 30d. The connecting wall 30e is generally parallel to the outward side 18c of the roof rail 18 and spaced apart from the outward side 18c of the roof rail 18.
The upper reinforcement member 32 overlaps and is secured to the first and second gusset tailgate motor mounting portions 14a, 16a of, respectively, the first and second gusset members 14, 16 along upper flanges 14f, 16f thereof. More particularly, the upper reinforcement member 32 can be secured to each of the first and second gusset tailgate motor mounting portions 14a, 16a, and particularly to the respective upper flanges 14f, 16f of the first and second gusset tailgate motor mounting portions 14a, 16a that are spaced apart from one another along a longitudinal length of the roof rail 18. More specifically, the first gusset tailgate motor mounting portion 14a includes the first gusset upper flange 14f to which the reinforcement member 32 overlaps and is secured (i.e., forming a first location at which the upper reinforcement member 32 is secured to the first and second gusset members 14, 16). Likewise, the second gusset tailgate motor mounting portion 16a includes the second gusset upper flange 16f to which the reinforcement member 32 overlaps and is secured (i.e., forming a second location at which the upper reinforcement member 32 is secured to the first and second gusset members 14, 16).
The first gusset upper flange 14f defines a clip aperture 42 for mounting an associated wire harness clip 44 at a location 46 spaced inwardly relative to the roof rail 18 and forwardly relative to the terminal rearward end 18b of the roof rail 18. The wire harness clip carries a wire harness 48 as best shown in
The roof rail 18 includes a roof rail upper flange 18d extending angularly relative to the inward side 18a (and the outward side 18c) of the roof rail 18. The roof rail upper flange 18d overlaps and is secured to an inward edge portion 32a of the reinforcement member 32. The reinforcement member 32 extends inwardly in a generally orthogonal orientation relative to the inward side 18a of the roof rail 18. The reinforcement member 32 also extends rearwardly from the first gusset member 14 and has a rearward portion 32b secured to a corner structure 50 (
