Abstract

A selectively detachable tailgate assembly for a vehicle is disclosed. The tailgate assembly includes a tailgate, a hinge mechanism, and a power assembly. The hinge mechanism connects the tailgate to a portion of a vehicle. A portion of the hinge mechanism may be selectively disassembled to permit the tailgate to be removed from the vehicle. The power assembly is operatively connected to the tailgate to provide power to the tailgate to selectively move the tailgate at least partially between the open and closed positions.

Claims

1. A selectively removable tailgate assembly for a vehicle, comprising:

a vehicle having a cargo area including a bed floor, a first side cargo wall disposed on a first lateral side of the bed floor, and a second side cargo wall disposed on a second lateral side of the bed floor, with respective rearward ends of the first and second side cargo walls defining a tailgate opening;

a tailgate movable between an open position and a closed position relative to the tailgate opening such that in the closed position the tailgate mates with the tailgate opening and the first and second side cargo walls and in the open position the tailgate exposes the cargo area extending the bed floor;

a hinge mechanism that connects a portion of the tailgate to a lower portion of a rearward end of the first side cargo wall and a lower portion of a rearward end of the first side cargo wall, wherein at least one portion of the hinge mechanism may be selectively detached from another portion of the hinge mechanism to permit the tailgate to be removed from the vehicle;

a power assembly operatively connected to the tailgate hinge mechanism to selectively move the tailgate at least partially between the open and closed positions; and

at least one pinch strip connected to at least one of the tailgate and a section of the vehicle proximate the tailgate opening, the pinch strip operative to detect an obstruction when closing the tailgate by the power assembly.

2. The selectively removable tailgate assembly of claim 1, wherein the hinge mechanism comprises:

a tailgate bracket connected to the tailgate; and

a clevis fixedly connected to a driveshaft, wherein the power assembly is operatively connected to the clevis to operate the driveshaft;

wherein the driveshaft selectively moves the tailgate between the open and closed positions.

3. The selectively removable tailgate assembly of claim 1, further including a tailgate cable having a first end connected to the vehicle and a second end connected to the tailgate;

wherein one of the first and second ends is selectively disconnectable to allow removal of the tailgate.

4. The selectively removable tailgate assembly of claim 1, further including a switch located on a portion of the vehicle, wherein the switch is electrically connected to the power assembly and may be activated by a user to operate the power assembly to open and close the tailgate.

6. The selectively removable tailgate assembly of claim 1, wherein

the tailgate and the hinge mechanism are configured such that the tailgate is removed from the vehicle and re-installed to the vehicle without tools.

7. The selectively removable tailgate assembly of claim 1, wherein

the tailgate pivots about a pivot axis that is defined by the hinge mechanism, the tailgate having a first end parallel and adjacent to the pivot axis, a second end opposite the first end, a first contact surface defined along a first lateral side that extends between the first and second ends of the tailgate and a second contact surface defined along a second lateral side that extends between the first and second ends of the tailgate with the pinch strip being disposed along at least one of the first and second contact surfaces.

8. The selectively removable tailgate assembly of claim 7, wherein

an additional pinch strip is disposed along the other of the first and second contact surfaces.

9. The selectively removable tailgate assembly of claim 1, wherein

the pinch strip is disposed along at least one of the rearward end of the first side cargo wall and the rearward end of the second side cargo wall of the cargo area of the vehicle.

10. The selectively removable tailgate assembly of claim 9, wherein

an additional pinch strip is disposed along a rearward end of the bed floor of the cargo area of the vehicle adjacent to the tailgate.

11. The selectively removable tailgate assembly of claim 1, wherein

the pinch strip is disposed along a rearward end of the bed floor of the cargo area of the vehicle adjacent to the tailgate.

12. The selectively removable tailgate assembly of claim 1, wherein

the at least one pinch strip is in electrical communication with the power assembly such that with the power assembly activated to move the tailgate between the open and closed positions, the power assembly stops movement of the tailgate in response to detection of an obstruction by the pinch strip.

13. The selectively removable tailgate assembly of claim 1, wherein

with the power assembly activated to move the tailgate between the open position and the closed position, the power assembly automatically returns the tailgate to the open position in response to detection of an obstruction by the pinch strip.

5. A selectively removable tailgate assembly, comprising:

a tailgate movable between an open position and a closed position;

a hinge mechanism that connects a portion of the tailgate to a portion of the vehicle, wherein at least one portion of the hinge mechanism may be selectively detached from another portion of the hinge mechanism to permit the tailgate to be removed from the vehicle;

a power assembly operatively connected to the tailgate hinge mechanism to selectively move the tailgate at least partially between the open and closed positions; and

at least one pinch strip connected to the tailgate, the pinch strip operative to detect an obstruction when closing the tailgate by the power assembly.

14. The selectively removable tailgate assembly of claim 5, wherein

the tailgate and the hinge mechanism are configured such that the tailgate is removed from the vehicle and re-installed to the vehicle without tools.

15. The selectively removable tailgate assembly of claim 5, wherein

the tailgate pivots about a pivot axis that is defined by the hinge mechanism, the tailgate having a first end parallel and adjacent to the pivot axis, a second end opposite the first end, a first contact surface defined along a first lateral side that extends between the first and second ends of the tailgate and a second contact surface defined along a second lateral side that extends between the first and second ends of the tailgate with the pinch strip being disposed along at least one of the first and second contact surfaces.

16. The selectively removable tailgate assembly of claim 15, wherein

an additional pinch strip is disposed along the other of the first and second contact surfaces.

17. The selectively removable tailgate assembly of claim 5, wherein

the vehicle has a cargo area including a bed floor, a first side cargo wall disposed on a first lateral side of the bed floor, and a second side cargo wall disposed on a second lateral side of the bed floor, with respective rearward ends of the first and second side cargo walls defining a tailgate opening such that in the closed position the tailgate mates with the tailgate opening and the first and second side cargo walls and in the open position the tailgate exposes the cargo area extending the bed floor, and

an additional pinch strip is disposed along surfaces at least one of the rearward ends of the first and second lateral sides of the bed floor.

18. The selectively removable tailgate assembly of claim 17, wherein

another additional pinch strip is disposed along a rearward end of the bed floor of the cargo area of the vehicle adjacent to the tailgate.

19. The selectively removable tailgate assembly of claim 5, wherein

the at least one pinch strip is in electrical communication with the power assembly such that with the power assembly activated to move the tailgate between the open and closed positions, the power assembly stops movement of the tailgate in response to detection of an obstruction by the pinch strip.

20. The selectively removable tailgate assembly of claim 5, wherein

with the power assembly activated to move the tailgate between the open position and the closed position, the power assembly automatically returns the tailgate to the open position in response to detection of an obstruction by the pinch strip.
