Abstract

A hinge assembly for a vehicle is provided having an internal passageway defined by mated slotted portions of the hinge and the door jamb, check assembly, mounted on the hinge and having a specifically configured free end extending through the passageway, and detent arrangement, mounted on the interior of the door jamb for engagement with the specifically configured free end of the check assembly to restrain rotation of the door in a primary intermediate open position. The specifically configured free end of the check assembly and the detent arrangement cooperated with one another so as to alternatively restrain rotation of the door in the primary intermediate open position and a less open secondary intermediate open position, and the check assembly is formed for releasable engagement with the detent arrangement to permit free rotation of the door to a fully open position.

Claims

1. A hinge assembly for a vehicle, said vehicle having a door jamb, a door and a hinge mounted therebetween, said door rotatable between closed and fully opened positions, comprising:

an internal passageway defined by mated slotted portions of said hinge and said door jamb;

check means, mounted on said hinge and having a specifically configured free and extending through said passageway; and

detent means, mounted on the interior of said door jamb, for engagement with said specifically configured free end of said check means to restrain rotation of said door in a primary intermediate open position, said check means being formed for releasable engagement with said detent means to permit free rotation of said door to said fully opened position.

2. The hinge assembly as defined in claim 1 wherein said specifically configured free end of said check means and said detent means cooperate with one another so as to alternatively restrain rotation of said door in said primary intermediate open position and a less open secondary intermediate position.

3. The hinge assembly as defined in claim 2 wherein said check means includes a metal ribbon, formed and positioned for resilient deformation upon rotation of said door.

4. The hinge assembly as defined in claim 3 wherein said metal ribbon includes a first curved portion extending from said mounted end to said passageway and a second, oppositely curved portion, extending from said passageway to said flanged end, said ribbon having a length dimension calibrated to restrain rotation of said door at said primary intermediate open position, said length dimension and said second curved portion cooperating to restrain rotation of said door at said second intermediate open position.

5. The hinge assembly as defined in claim 4 wherein said primary intermediate open position is about 90 degrees from said closed position.

6. A hinge assembly for a vehicle having a door jamb, a door and a hinge mounted therebetween, said door rotatable between closed and fully opened positions, comprising:

first means movable with said door and second means connected with said jamb, said first and second means cooperating with one another in a first way for maintaining said door open in a primary intermediate position approximately 90°

from said closed position, in a second way for maintaining said door open in a secondary intermediate position between said first and closed positions and approximately 80°

from said closed position, and in a third way for allowing said door to move to its fully opened position, said first means including a resiliently deformable metal ribbon attached at one end to said door and having a first curved portion extending therefrom, a second, oppositely curved medial portion and a specifically configured flanged end, said ribbon including a slot disposed between said second oppositely curved medial portion and said specifically configured flanged end, said slot having upwardly extending walls and a width dimensioned for receipt of said second means upon rotation of said door to said primary intermediate open position.

7. The hinge assembly according to claim 6 wherein said second portion and said flanged end extend through an internal passageway defined by mating slotted portions of said hinge and said door jamb, and wherein said second means includes a stop, formed and positioned for engagement with said flanged end when said door is opened to said primary intermediate position.

8. The hinge assembly according to claim 7 wherein said first curved portion is disposed in concave relation to the interior of the vehicle and the flange of said specifically configured flanged end is disposed toward the interior of said vehicle.

9. The hinge assembly according to claim 6 wherein said second means includes a detent formed and positioned for engagement with said flanged end when said door is opened to said primary intermediate position.

10. A hinge assembly for a vehicle having a door jamb, a door and a hinge mounted therebetween, said door rotatable between closed and fully opened positions, comprising:

(a) an internal passageway defined by mating slotted portions of said hinge and said door jamb;

(b) a resiliently deformable metal ribbon, attached at one end to said door and having a first curved portion extending therefrom, said first curve portion being disposed in concave relation to the interior of said vehicle, a second, oppositely curved, medial portion, a flanged end having a flange disposed toward the interior of said vehicle, and a channel disposed between said medial portion and said flanged end having upwardly extending walls, said channel and said flanged end extending through said internal passageway in said closed position; and

(c) a detent, mounted on the interior of said door jamb for engagement with said flanged end upon rotation of said door;

said ribbon being formed for releasable engagement with said detent to permit free rotation of said door to said fully open position.
