Abstract

A vehicle includes a vehicle body, a tailgate and a hinge assembly. The tailgate is rotatable relative to the vehicle body between a closed position and an open position. The hinge assembly rotatably coupling the tailgate to the vehicle body. The hinge assembly includes a bracket, a hinge pin and a retention ring. The bracket is attached to a respective one of a plurality of side walls of the vehicle body. The hinge pin is rotatably fixed to a respective end of the tailgate and is removably connected to the bracket. The retention ring is rotatably coupled to the bracket between a locked state in which the hinge pin is prevented from being disconnected from the bracket and an unlocked state in which the hinge pin is permitted to be disconnected from the bracket.

First claim

What is claimed is:

1. A vehicle comprising:
a vehicle body;
a tailgate rotatable relative to the vehicle body between a closed position and an open position; and
a hinge assembly rotatably coupling the tailgate to the vehicle body, the hinge assembly including a bracket, a hinge pin and a resiliently flexible retention ring, the bracket attached to a respective one of a plurality of side walls of the vehicle body, the hinge pin rotatably fixed to a respective end of the tailgate and removably connected to the bracket, the retention ring rotatably coupled to the bracket between a locked state in which the hinge pin is prevented from being disconnected from the bracket and an unlocked state in which the hinge pin is permitted to be disconnected from the bracket.

2. The vehicle of claim 1 , wherein the bracket includes a mounting portion and a hinge-pin housing, and wherein the mounting portion is attached to the respective one of the plurality of side walls and the hinge pin is disposed within the hinge-pin housing.

3. The vehicle of claim 2 , further comprising a bushing disposed within the hinge-pin housing, and wherein the hinge pin is received in a slot formed in the bushing.

4. The vehicle of claim 3 , wherein the bushing and the hinge pin rotate relative to the bracket and the retention ring when the retention ring is in the locked state and the tailgate is rotated between the open position and the closed position.

5. The vehicle of claim 4 , wherein the hinge-pin housing is positioned between the bushing and the retention ring.

6. The vehicle of claim 2 , wherein the retention ring is at least partially wrapped around the hinge-pin housing.

7. The vehicle of claim 6 , wherein the retention ring includes a body and a protrusion, and wherein the protrusion extends radially inwardly from an inner surface of the body.

8. The vehicle of claim 7 , wherein the protrusion contacts an outer surface of the hinge-pin housing when the retention ring is in the unlocked state.

9. The vehicle of claim 8 , wherein the hinge-pin housing includes a housing opening formed therein, and wherein the protrusion is disposed in the housing opening when the retention ring is in the locked state to prevent the hinge pin from being removed from the hinge-pin housing.

10. The vehicle of claim 9 , wherein the body of the retention ring defines a retention-ring opening, and wherein the hinge pin is permitted to be removed from the hinge-pin housing via the housing opening and the retention-ring opening when the retention ring is in the unlocked state and the tailgate is in the open position.

11. The vehicle of claim 10 , wherein a width of the retention-ring opening is wider than a width of the housing opening.

12. The vehicle of claim 10 , wherein the retention ring includes at least one gripping member extending radially outwardly from an outer surface of the body.

13. The vehicle of claim 1 , wherein the retention ring is made of a polymeric material.

14. The vehicle of claim 1 , wherein the retention ring is C-shaped.

15. A vehicle comprising:
a vehicle body;
a tailgate rotatable relative to the vehicle body between a closed position and an open position; and
a hinge assembly rotatably coupling the tailgate to the vehicle body, the hinge assembly including a bracket having a hinge pin housing extending outward from the bracket, a bushing coupled to the hinge pin housing, a hinge pin, and a retention ring,
wherein the bracket is attached to a respective one of a plurality of side walls of the vehicle body, the hinge pin is rotatably fixed to a respective end of the tailgate and removably connected to the hinge pin housing via the bushing, and the retention ring is rotatably coupled to the hinge pin housing between a locked state in which the hinge pin is prevented from being disconnected from the bracket and an unlocked state in which the hinge pin is permitted to be disconnected from the bracket,
wherein the bushing includes a flexible tab that extends through the hinge pin housing toward the bracket that couples the bushing to the hinge pin housing, and
wherein the bushing and the hinge pin rotate relative to the hinge pin housing and the retention ring when the retention ring is in the locked state and the tailgate is rotated between the open position and the closed position.

16. The vehicle of claim 15 , wherein the retention ring is resiliently flexible.

17. A hinge assembly configured to rotatably couple a tailgate to a vehicle body including a plurality of sidewalls, the hinge assembly comprising a bracket, a hinge pin and a resiliently flexible retention ring, the bracket being configured to be attached to a respective one of the plurality of side walls of the vehicle body, the hinge pin is configured to be rotatably fixed to a respective end of the tailgate and removably connected to the bracket, and the retention ring rotatably is coupled to the bracket between a locked state in which the hinge pin is prevented from being disconnected from the bracket and an unlocked state in which the hinge pin is permitted to be disconnected from the bracket.

18. The hinge assemble according to claim 17 , wherein the bracket includes a mounting portion and a hinge-pin housing; and
the mounting portion is attached to the respective one of the plurality of side walls and the hinge pin is disposed within the hinge-pin housing.

19. The hinge assembly according to claim 18 , further comprising a bushing disposed within the hinge-pin housing,
wherein the hinge pin is received in a slot formed in the bushing, and the bushing and the hinge pin rotate relative to the bracket and the retention ring when the retention ring is in the locked state and the tailgate is rotated between the open position and the closed position.
