Abstract

A hinge assembly for a first door of a pair of opposing-hinged doors includes a curved extension, a first pivot connection interconnecting the curved extension and a body of the vehicle, and a second pivot connection interconnecting the curved extension and the first door. When opening the first door, a first edge of the first door pivots about the first pivot connection away from the body and draws a second edge of the door away from an adjacent second door. The first door pivots about the second pivot connection to open the first door independently of the adjacent second door.

Claims

1. A vehicle comprising:

a body;

a first door having a first edge and a second edge spaced from the first edge, wherein the first door is moveable between a closed position, an intermediate position and an open position; and

a hinge assembly pivotably coupling the first door to the body, the hinge assembly including;

a curved extension having a first end and a second end;

a first pivot connection pivotably interconnecting the first end of the curved extension and the body; and

a second pivot connection pivotably interconnecting the second end of the curved extension and the second edge of the first door;

wherein the curved extension pivots about the first pivot connection into a pivot position when moving from the closed position into the intermediate position to move the second edge of the first door laterally away from the body and to move the first edge of the first door parallel with the body; and

wherein the first door pivots about the second pivot connection in a first direction when moving from the intermediate position into the open position to swing the first edge of the first door laterally away from the body.

2. A vehicle as set forth in claim 1 wherein the hinge assembly includes a first bracket pivotably coupled to the first end of the curved extension to define the first pivot connection.

3. A vehicle as set forth in claim 2 wherein the hinge assembly includes a first pin interconnecting the first bracket and the first end of the curved extension and defining a first pivot axis.

4. A vehicle as set forth in claim 2 wherein the hinge assembly includes a biasing device coupled to the first bracket and the first end of the curved extension and configured for biasing the curved extension into the pivot position.

5. A vehicle as set forth in claim 4 wherein the biasing device includes a torsion spring.

6. A vehicle as set forth in claim 3 wherein the hinge assembly includes a second bracket pivotably coupled to the second end of the curved extension to define the second pivot connection.

7. A vehicle as set forth in claim 6 wherein the hinge assembly includes a second pin interconnecting the second bracket and the second end of the curved extension and defining a second pivot axis.

8. A vehicle as set forth in claim 7 wherein the first pivot axis is parallel with the second pivot axis, and wherein the curved extension includes a non-linear shape extending between the first pivot axis and the second pivot axis.

9. A vehicle as set forth in claim 6 further comprising an actuator interconnecting the body and the curved extension and configured to move the curved extension from the pivot position into a stowed position.

10. A vehicle as set forth in claim 9 wherein the actuator includes an electro-mechanical device.

11. A vehicle as set forth in claim 9 further comprising a latch mechanism disposed adjacent the first edge of the first door and configured for restricting lateral movement of the first edge of the first door away from the vehicle when the first door is in the closed position or moving between the closed position and the intermediate position, wherein the actuator engages the first door in interlocking engagement when the first door moves from the open position into the intermediate position.

12. A vehicle as set forth in claim 11 wherein the actuator moves the curved extension from the pivot position into the stowed position to move the first door into the closed position upon the latch mechanism engaging the first door in interlocking engagement when the first door moves from the open position into the intermediate position.

13. A vehicle as set forth in claim 1 further comprising a second door disposed adjacent the first door and pivotably attached to the body for pivotable movement in a second direction opposite the first direction, wherein movement of the first door from the closed position into the intermediate position moves the first door away from the second door.

14. A hinge assembly for pivotably coupling a first door to a body of a vehicle, the hinge assembly comprising:

a curved extension having a first end and a second end;

a first pivot connection configured for pivotably interconnecting the first end of the curved extension and the body; and

a second pivot connection configured for pivotably interconnecting the second end of the curved extension and the first door;

wherein the curved extension pivots about the first pivot connection into a pivot position to move the first door laterally away from and parallel with the body; and

wherein the first door pivots about the second pivot connection in a first direction to move into an open position.

15. A hinge assembly as set forth in claim 14 further comprising a first bracket pivotably coupled to the first end of the curved extension to define the first pivot connection.

16. A hinge assembly as set forth in claim 15 further comprising a first pin interconnecting the first bracket and the first end of the curved extension and defining a first pivot axis.

17. A hinge assembly as set forth in claim 15 further comprising a biasing device coupled to the first bracket and the first end of the curved extension and configured for biasing the curved extension into the pivot position.

18. A hinge assembly as set forth in claim 16 further comprising a second bracket pivotably coupled to the second end of the curved extension to define the second pivot connection.

19. A hinge assembly as set forth in claim 18 further comprising a second pin interconnecting the second bracket and the second end of the curved extension and defining a second pivot axis.

20. A hinge assembly as set forth in claim 19 wherein the first pivot axis is parallel with the second pivot axis, and wherein the curved extension includes a non-linear shape extending between the first pivot axis and the second pivot axis.
