Abstract

A tailgate assembly includes a structure, and a handle assembly attached to the structure. The handle assembly is moveable relative to the structure between a stowed position, an intermediate position, and a deployed position. The handle assembly includes a connecting member that is attached to the structure. The connecting member is rotatable about a first axis relative to the structure. A handle portion is attached to the connecting member, and is rotatable about a second axis relative to the connecting member. The handle portion and the connecting member rotate in unison relative to the structure about the first axis, between the stowed position and the intermediate position, to position the handle portion outside an interior space of the structure. The handle portion rotates relative to the connecting member about the second axis, between the intermediate position and the deployed position, whereby a user may grasp the handle portion.

First claim

The invention claimed is:

1. A tailgate assembly for a vehicle, the tailgate assembly comprising:
a structure;
a handle assembly attached to the structure and moveable between a stowed position, an intermediate position, and a deployed position, wherein the handle assembly includes:
a connecting member attached to the structure and rotatable about a first axis relative to the structure;
a handle portion attached to the connecting member and rotatable about a second axis relative to the connecting member;
wherein the handle portion and the connecting member rotate in unison relative to the structure about the first axis between the stowed position and the intermediate position; and
wherein the handle portion rotates relative to the connecting member about the second axis between the intermediate position and the deployed position.

2. The tailgate assembly set forth in claim 1 wherein the second axis is transverse to the first axis, and wherein the second axis is laterally offset relative to the first axis.

3. The tailgate assembly set forth in claim 2 wherein the handle assembly includes a first pivot pin interconnecting the structure and the connecting member, wherein a central longitudinal axis of the first pivot pin defines the first axis.

4. The tailgate assembly set forth in claim 3 wherein the handle assembly includes a second pivot pin interconnecting the handle portion and the connecting member, wherein a central longitudinal axis of the second pivot pin defines the second axis.

5. The tailgate assembly set forth in claim 1 wherein the handle assembly includes a first latch operable to latch the interconnecting member to the structure when the handle assembly is disposed in the intermediate position and the deployed position.

6. The tailgate assembly set forth in claim 5 wherein the structure includes a catch, and the first latch is pivotably attached to and supported by the connecting member, wherein the first latch is operable to engage the catch in latching engagement when the handle assembly is disposed in the intermediate position and the deployed position.

7. The tailgate assembly set forth in claim 6 further comprising a first biasing device interconnecting the first latch and the structure, and biasing the first latch against the structure.

8. The tailgate assembly set forth in claim 1 wherein the handle assembly includes a second latch operable to latch the handle portion to the connecting member when the handle portion is disposed in the deployed position.

9. The tailgate assembly set forth in claim 8 wherein the connecting member includes a striker pin extending outward from the connecting member in parallel with the second axis.

10. The tailgate assembly set forth in claim 9 wherein the second latch is rotatably attached to and supported by the handle portion, and includes a notch operable to receive the striker pin therein when the handle portion is disposed in the deployed position.

11. The tailgate assembly set forth in claim 10 further comprising a second biasing device interconnecting the second latch and the handle portion, and biasing the second latch against the striker pin.

12. The tailgate assembly set forth in claim 1 further comprising a stowage clip attached to the structure and operable to secure the handle portion in the stowed position relative to the structure.

13. The tailgate assembly set forth in claim 1 wherein the structure defines an interior space, with the handle assembly disposed within the interior space when in the stowed position, and wherein the tailgate assembly further comprises a deployable step attached to the structure and moveable between a stowed position concealing the handle assembly within the interior space of the structure, and a lowered position presenting a step and exposing the handle assembly.

14. A vehicle comprising:
a body;
a tailgate assembly having a structure moveably attached to the body, and defining an interior space;
wherein the tailgate assembly includes a handle assembly attached to the structure and moveable between a stowed position, an intermediate position, and a deployed position, and wherein the tailgate assembly further includes a deployable step attached to the structure and moveable between a raised position concealing the handle assembly in the stowed position within the interior space of the structure, and a lowered position presenting a step and exposing the handle assembly;
wherein the handle assembly includes:
a connecting member attached to the structure and rotatable about a first axis relative to the structure;
a handle portion attached to the connecting member and rotatable about a second axis relative to the connecting member;
wherein the handle portion and the connecting member rotate in unison relative to the structure about the first axis between the stowed position and the intermediate position; and
wherein the handle portion rotates relative to the connecting member about the second axis between the intermediate position and the deployed position.

15. The vehicle set forth in claim 14 wherein the second axis is transverse to the first axis, and wherein the second axis is laterally offset relative to the first axis.

16. The vehicle set forth in claim 14 wherein the structure includes a catch, and wherein the handle assembly includes a first latch pivotably attached to and supported by the connecting member, and operable to engage the catch in latching engagement when the handle assembly is disposed in the intermediate position and the deployed position.

17. The vehicle set forth in claim 16 wherein the connecting member includes a striker pin extending outward from the connecting member in parallel with the second axis, and wherein the handle assembly includes a second latch rotatably attached to and supported by the handle portion, wherein the second latch includes a notch operable to receive the striker pin therein when the handle portion is disposed in the deployed position to latch the handle portion to the connecting member.

18. The vehicle set forth in claim 17 further comprising a first biasing device interconnecting the first latch and the structure, and biasing the first latch against the structure, and a second biasing device interconnecting the second latch and the handle portion, and biasing the second latch against the striker pin.
