Multiple axis hinge for a vehicle body side door
View Patent ↗A vehicle door hinge assembly includes a first hinge supported to pivot about a first axis, a guide surface, a door located at a side of the vehicle, a bracket to which the door is secured, supported to pivot about the first axis and a second axis and including a follower engaged with the guild surface, and a strut secured to the bracket that extends as the bracket pivots toward an open position and retracts as the bracket pivots toward a closed position.
1. A hinge assembly for a door of a vehicle comprising:
a first bracket able to be fixed in position on the vehicle;
a first hinge supported to pivot on the first bracket about a first axis;
a second bracket supported on the first hinge, to pivot about a second axis and including a follower engaged with a guide surface formed on a block secured to the first bracket, said guide surface having a variable slope that increases as a distance between the follower and the first bracket increases as the second bracket moves toward an open position; and
a displaceable strut secured to the first and second brackets throughout a range of motion between open and closed positions for holding the second bracket in an the open position.
2. The hinge assembly of claim 1 , wherein the strut is secured to the second bracket at a location eccentric of the second axis such that the strut extends and retracts as the door opens and closes.
3. The hinge assembly of claim 1 , wherein the first axis is substantially vertical and the second axis is substantially horizontal.
4. The hinge assembly of claim 1 , wherein the first and second axes are mutually perpendicular.
5. The hinge assembly of claim 1 , wherein the second bracket includes a surface onto which the door is secured to the second bracket.
6. The hinge assembly of claim 1 , wherein engagement of the follower with the guide surface is maintained throughout a range of motion between the open and closed positions.
7. A hinge assembly for a vehicle, comprising:
a first hinge supported to pivot about a first axis;
a bracket supported to pivot about the first axis and a second axis and including a follower engaged with a guide surface over a range of motion between open and closed positions;
a body side bracket able to be fixed in position on the vehicle, including a block formed with the guide surface, the guide surface having a variable slope that increases as a distance between the follower and the body side bracket increases as the hinge assembly moves toward the open position; and
a strut secured to the bracket and the vehicle over a range of motion between the open and closed positions.
8. The hinge assembly of claim 7 , wherein the strut is secured to the bracket at a location eccentric of the second axis.
9. The hinge assembly of claim 7 , further comprising a body side bracket able to be fixed in position on the vehicle and to which the first hinge is secured to pivot about the first axis.
10. The hinge assembly of claim 7 , wherein the first axis is substantially vertical and the second axis is substantially horizontal.
11. The hinge assembly of claim 7 , wherein the first and second axes are mutually perpendicular.
12. The hinge assembly of claim 7 , further comprising a block secured to a body side bracket and contacting the bracket, said contact maintaining the follower engaged with the guide surface as the door opens and closes over a range of motion between the open and closed positions.
13. A hinge assembly for a door of a vehicle comprising:
a first bracket able to be fixed in position on the vehicle;
a first hinge supported to pivot on the first bracket about a first axis;
a second bracket supported on the first hinge to pivot about a second axis;
a follower attached to the second bracket and with a guide surface for guiding movement of the door relative to the first bracket throughout a range of motion of the door between open and closed positions;
a guide surface formed on a block that is secured to the first bracket, the guide surface having a variable slope that increases as a distance between the follower and the first bracket increases as the second bracket moves toward the open position; and
a strut secured to the first and second brackets throughout a range of motion of the door between the open and closed positions.
14. The hinge assembly of claim 13 , wherein the guide surface is secured to the first bracket.
15. The hinge assembly of claim 13 , wherein the follower is secured to the second bracket.
