Abstract

A door assembly includes a door frame, which generally defines a door opening. An assist handle is movably attached to the door frame. The assist handle is movable between a retracted position, proximal to the door frame, and a deployed position, distal from the door frame.

First claim

The invention claimed is:

1. A door assembly, comprising:
a door frame defining a door opening; and
an assist handle movably attached to the door frame,
wherein the assist handle is rotatable with respect to the door frame between a retracted position, proximal to the door frame, and a deployed position, distal from the door frame.

2. The door assembly of claim 1 , further comprising:
a hinge attaching the assist handle to the door frame, wherein the hinge defines a first axis, about which the assist handle rotates between the retracted position and the deployed position.

3. The door assembly of claim 2 ,
wherein the deployed position is a first deployed position,
wherein the assist handle is movably attached to a rearward side of the door frame, such that the assist handle extends forward into the door opening when moving from the retracted position to the deployed position,
wherein the hinge defines a second axis, substantially perpendicular to the first axis, and
wherein the assist handle is further movable to a second deployed position, rotated about the second axis, such that the second position is substantially perpendicular to the door opening.

4. The door assembly of claim 3 , further comprising:
a return mechanism biasing the assist handle toward the retracted position.

5. The door assembly of claim 4 , further comprising:
a power actuator attached to the assist handle and the door frame, wherein the power actuator is configured to actuate the assist handle from the retracted position to at least one of the first deployed position and the second deployed position.

6. The door assembly of claim 1 , further comprising:
a return mechanism biasing the assist handle toward the retracted position.

7. The door assembly of claim 2 ,
wherein the deployed position is a first deployed position,
wherein the assist handle is movably attached to a perimeter of the door frame and the assist handle extends into the door opening when moving from the retracted position to the deployed position,
wherein the hinge defines a second axis, substantially perpendicular to the first axis, and
wherein the assist handle is further movable to a second deployed position, rotated about the second axis, such that the second position is substantially perpendicular to the door opening.

8. The door assembly of claim 1 , further comprising:
a power actuator attached to the assist handle and the door frame, wherein the power actuator actuates the assist handle from the retracted position to the deployed position.

9. The door assembly of claim 8 , further comprising:
a door movable with respect to the door frame between a closed position, which blocks the door opening, and an open position, which allows access to the door opening; and
a latch selectively adjustable between a locked setting, which restrains the door in the closed position, and a free setting, which allows the door to move between the closed position and the open position,
wherein placing the latch in the free setting and actuating the assist handle, with the power actuator, from the retracted position to the deployed position moves the door from the closed position to the open position.

10. A vehicle, comprising:
a door frame defining a door opening;
a door movable with respect to the door frame between a closed position, which blocks the door opening, and an open position, which allows access to the door opening;
an assist handle movably attached to the door frame opposite a pivot point of the door, wherein the assist handle is movable between a retracted position, proximal to the door frame, and a deployed position, distal from the door frame, when the door is in the open position;
a latch selectively adjustable between a locked setting, which restrains the door in the closed position, and a free setting, which allows the door to move between the closed position and the open position; and
a power actuator attached to the assist handle and the door frame, wherein the power actuator moves the assist handle from the retracted position to the deployed position, such that the assist handle moves the door from the closed position to the open position when the latch is in free setting.

11. The vehicle of claim 10 , further comprising:
a return mechanism biasing the assist handle toward the retracted position.

12. A method of operating a door mechanism having a door frame defining a door opening and a door selectively movable relative to the door opening, the method comprising:
adjusting a latch from a locked setting, which restrains the door in a closed position that blocks the door opening, to a free setting, which allows the door to move between the closed position and an open position that allows access to the door opening;
actuating an assist handle movably attached to the door frame opposite a pivot point of the door, such that the assist handle moves from a retracted position, proximal to the door frame, to a deployed position, distal from the door frame; and
moving the door from the closed position to the open position with the assist handle.

13. The method of claim 12 , wherein actuating the assist handle occurs via a power actuator attached to the assist handle and the door frame, such that the power actuator moves the assist handle from the retracted position to the deployed position and moves the door from the closed position to the open position.

14. The door assembly of claim 1 , wherein the assist handle is within a cavity of the door frame when in the retracted position.

15. The door assembly of claim 14 , wherein the assist handle is movably attached to a pillar, such that the retracted position is within a cavity of the pillar and the deployed position extends from the pillar.

16. The door assembly of claim 6 , wherein the assist handle is within a cavity of the door frame when in the retracted position, such that the return mechanism biases the door handle toward the cavity.

17. The door assembly of claim 8 , wherein the assist handle is within a cavity of the door frame when in the retracted position, such that the power actuator actuates the assist handle from the cavity to extend into the door opening when in the deployed position.

18. The door assembly of claim 9 , wherein the assist handle is movably attached to a pillar, such that the retracted position is within a cavity of the pillar and the deployed position extends from the pillar.
