## Abstract

An exemplary tailgate assembly includes, among other things, a first gate pivotably coupled to a vehicle body, and a second gate pivotably coupled to the first gate. The second gate has an inner surface that faces a vehicle cargo bed when the second gate is in a closed position. The first and second gates are moveable to a step position where the inner surface is a step surface to the vehicle cargo bed. An exemplary method includes, among other things, pivoting a first and a second gate to a step position where an inner surface of the second gate is a step surface to a vehicle cargo bed. The inner surface faces the vehicle cargo bed when the second gate is in a closed position.

## Claims

### Claim 1

A tailgate assembly, comprising:
a first gate pivotably coupled to a vehicle body; and
a second gate pivotably coupled to the first gate, the second gate having an inner surface that faces a vehicle cargo bed when the second gate is in a closed position, the first and second gates moveable to a step position where the inner surface is a step surface to the vehicle cargo bed, the first gate having an inner surface that is vertically aligned with a plane of the vehicle cargo bed when in the step position.

### Claim 2 (depends on 1)

The tailgate assembly of claim 1, wherein each portion of the first gate is vertically displaced from each portion of the second gate when the first and second gates are in the step position.

### Claim 3 (depends on 1)

The tailgate assembly of claim 1, wherein the first gate is in an open position when the first and second gates are in the step position.

### Claim 4 (depends on 1)

The tailgate assembly of claim 1, further comprising an articulation assembly coupled to the first gate at a first pivot and coupled to the second gate at a second pivot.

### Claim 5 (depends on 4)

The tailgate assembly of claim 4, wherein the first pivot is vertically above the second pivot when the first and second gates are in the step position.

### Claim 6 (depends on 4)

The tailgate assembly of claim 4, wherein the articulation assembly is configured to pivot relative to the first gate about the first pivot in a first direction to position the second gate in the step position, wherein the second gate is configured to pivot relative to the articulation assembly about the second pivot in a second direction to place the second gate in the step position, the first direction opposite the second direction.

### Claim 7 (depends on 6)

The tailgate assembly of claim 6, wherein, when the first gate is in an open position to provide an extended vehicle cargo bed, the articulation assembly is configured to pivot relative to the first gate to a position where the first and the second pivots are substantially vertically aligned, and the second gate is configured to pivot about the second pivot to the closed position to provide a closed tailgate for the extended vehicle cargo bed.

### Claim 8 (depends on 7)

The tailgate assembly of claim 7, further comprising a first cable assembly coupling the vehicle body to the first gate in the open position, and a second cable assembly coupling the second gate to the vehicle body when the second gate is providing the closed tailgate for the extend vehicle cargo bed.

### Claim 9 (depends on 4)

The tailgate assembly of claim 4, wherein the second gate is slideable between an extended position and a retracted position relative to the first gate.

### Claim 10 (depends on 9)

The tailgate assembly of claim 9, wherein an interior area of the first gate, the second gate, or both receives at least some of the articulation assembly when the second gate is in the retracted position.

### Claim 11 (depends on 9)

The tailgate assembly of claim 9, further comprising a latch assembly that is selectively actuated to allow the second gate to transition from the retracted position to the extended position.

### Claim 12 (depends on 9)

The tailgate assembly of claim 9, wherein the second gate is pivotable to the step position when the second gate is in the extended position, and the second gate is blocked from pivoting when the second gate is in the retracted position.

### Claim 13 (depends on 4)

The tailgate assembly of claim 4, wherein the articulation assembly has a longitudinal axis, and the longitudinal axis extends vertically when the first gate and the second gate are in the step position.

### Claim 14 (depends on 1)

The tailgate assembly of claim 1, wherein the first gate and the second gate are disposed along horizontal planes when in the step position.

### Claim 15 (depends on 1)

The tailgate assembly of claim 1, wherein the step surface extends across an entire width of the vehicle cargo bed and is generally parallel to ground level when the first and second gates are in the step position.

### Claim 16

A method, comprising:
pivoting a first and a second gate to a step position where an inner surface of the first gate is vertically aligned with a plane of a floor of a vehicle cargo bed, and an inner surface of the second gate is a step surface to the vehicle cargo bed, the inner surface of the second gate facing the vehicle cargo bed when the second gate is in a closed position.

### Claim 17 (depends on 16)

The method of claim 16, wherein the first gate is pivotably attached to vehicle body, and the second gate is pivotably attached to the first gate through an articulation assembly.

### Claim 18 (depends on 17)

The method of claim 17, further comprising moving the second gate to an extended position relative to the articulation assembly and the first gate prior to pivoting the second gate to the step position, the second gate spaced a distance from the first gate when in the extended position.

### Claim 19 (depends on 17)

The method of claim 17, wherein the articulation assembly includes an articulation arm having a first end portion coupled to the first gate through a first pivot, and an opposing, second end portion is coupled to the second gate through a second pivot, and
further comprising pivoting the articulation arm about the first pivot relative to the first gate in a first direction when moving the second gate to the step position, and pivoting the second gate about the second pivot relative to the articulation arm in a second direction when moving the second gate to the step position, the first direction opposite the second direction.

### Claim 20

A method, comprising:
pivoting a first and a second gate to a step position where an inner surface of the second gate is a step surface to a vehicle cargo bed, the inner surface facing the vehicle cargo bed when the second gate is in a closed position; and
selectively pivoting the first and second gates to an extended bed position where the first gate is in an open position to provide an extended vehicle cargo bed, and the inner surface of the second gate faces the extended vehicle cargo bed to provide a closed tailgate for the extended vehicle cargo bed.
