Abstract

A vehicle liftgate assembly according to an exemplary aspect of the present disclosure includes, among other things, a vehicle body, a liftgate bracket, a liftgate rotatably mounted to the vehicle body by way of the liftgate bracket, and a strut connected to the liftgate bracket to regulate rotational movement of the liftgate bracket. This disclosure also relates to a method and a rotation assembly, which may include a liftgate bracket and a flipglass bracket.

First claim

The invention claimed is:

1. A vehicle liftgate assembly, comprising:
a vehicle body;
a liftgate bracket;
a liftgate rotatably mounted to the vehicle body by way of the liftgate bracket;
a strut connected to the liftgate bracket to regulate rotational movement of the liftgate bracket;
wherein the liftgate bracket includes a bearing rotatable about a shaft, the bearing including a ring provided within a housing and disposed about the shaft, the ring being rotatable relative to the housing and the shaft; and
wherein the strut is connected directly to an outer face of the ring.

2. The assembly as recited in claim 1 , wherein the liftgate bracket includes a first bearing bed and a second bearing bed, the first bearing bed provided between the ring and the housing, and the second bearing bed provided between the ring and the shaft.

3. The assembly as recited in claim 1 , wherein the liftgate bracket includes a bracket arm projecting from the ring, wherein the bracket arm is connected to the liftgate.

4. The assembly as recited in claim 1 , wherein:
the liftgate includes a flipglass window,
the liftgate assembly further comprises a flipglass bracket connected to the flipglass window, and
the flipglass bracket is rotatably mounted about the shaft.

5. The assembly as recited in claim 4 , further comprising a torsion spring disposed about the shaft and connected to the flipglass bracket, the torsion spring regulating rotation of the flipglass bracket.

6. The assembly as recited in claim 4 , wherein:
the liftgate bracket is a first liftgate bracket and the flipglass bracket is a first flipglass bracket,
the first liftgate bracket and the first flipglass bracket provide a first rotation assembly, and
the liftgate assembly includes a second rotation assembly having a second liftgate bracket and a second flipglass bracket rotatably connected to the liftgate and the flipglass window, respectively.

7. The assembly as recited in claim 6 , wherein the second liftgate bracket and the second flipglass bracket are rotatably mounted about a second shaft.

8. The assembly as recited in claim 6 , wherein a second strut is connected to the second liftgate bracket to regulate rotational movement of the second liftgate bracket.

9. The assembly as recited in claim 1 , wherein the shaft is connected to the vehicle body by a mount.

10. The assembly as recited in claim 1 , wherein the strut is mounted substantially within the vehicle body such that the strut is substantially not visible from a vehicle exterior.

11. The assembly as recited in claim 1 , wherein the liftgate is a liftgate of a sport utility vehicle (SUV).

12. A vehicle liftgate assembly, comprising:
a vehicle body;
a liftgate bracket;
a liftgate rotatably mounted to the vehicle body by way of the liftgate bracket;
a strut connected to the liftgate bracket to regulate rotational movement of the liftgate bracket;
wherein the liftgate bracket includes a bearing rotatable about a shaft, the bearing including a ring provided within a housing and disposed about the shaft, the ring being rotatable relative to the housing and the shaft;
wherein the liftgate bracket includes a bracket arm projecting from the ring, wherein the bracket arm is connected to the liftgate; and
wherein the housing includes an opening, the bracket arm projecting through the opening.

13. The assembly as recited in claim 12 , wherein:
the housing includes a first stop and a second stop,
the first and second stops are provided on opposite sides of the opening,
the bracket arm abuts the first stop when the liftgate is in a fully open position, and
the bracket arm abuts the second stop when the liftgate is in a closed position.
