Double-pivot hinge for motor vehicle door
DCFirst Claim
1. A double pivot door hinge for a door of a motor vehicle comprising:
- a first hinge assembly, the first hinge assembly including a first door connector for connecting to the door of the motor vehicle, a first pillar connector for connecting to a door pillar or body of the motor vehicle, and a first link rotatably connected to the fist door connector at a first door-side pivot and rotatably connected to the first pillar connector at a first pillar-side pivot;
a second hinge assembly, the second hinge assembly including a second door connector for connecting to the door and a second pillar connector for connecting to the door pillar or the body, and a second link rotatably connected to the second door connector at a second door-side pivot and rotatably connected to the second pillar connector at a second pillar-side pivot; and
a connecting member rigidly joining the first and second hinge assemblies;
wherein a rotation of the first link at the first door-side pivot is resisted by a first braking resistance at the first door-side pivot and a rotation of the first link at the first pillar-side pivot is resisted by a second braking resistance at the first pillar-side pivot, the second braking resistance being less than the first braking resistance during opening.

42. A method for providing a hinge to open a vehicle door comprising the steps of:
-
providing a first pivot to connect the vehicle door and a first link;
providing a second pivot to connect the first link to a vehicle body;
providing a third pivot to connect the vehicle door and a second link, the third pivot being aligned with the first pivot at a door-side axis of rotation;
providing a fourth pivot to connect the second link to the vehicle body, the fourth pivot being aligned with the second pivot at a pillar-side axis of rotation;
providing a connecting member to rigidly join the first and second links;
permitting the second and fourth pivots to rotate when the door opens from a closed position to an intermediate position, while keeping the first and third pivots rotationally stationary, and permitting the first and third pivots to rotate when the door opens from the intermediate position to a fully open position while the second and fourth pivots remain rotationally stationary. - View Dependent Claims (43, 44, 45)
