Abstract: A hinge and lock assembly for releasably mounting a vehicle door on a door pillar of a vehicle including two hinge flaps attachable to the door and the door pillar, respectively, a hinge pin for pivotally connecting the two flaps with each other, a support releasably attachable to the door pillar for attaching the hinge to the door pillar an indexing arrangement formed on the hinge flap attachable to the door pillar and including alternating, following each other projections and indentations which cooperate with the torsion bar of the door lock for locking the door in a predetermined position, and a plurality of holding members pivotally supported on one leg of the door pillar hinge flap and cooperating with respective indentations of the indexing arrangement for holding a weighting arm of the torsion bar.

Abstract: A door lock for a motor vehicle door, and which is to be formed integrally with a motor vehicle door hinge, including a torsional spring supportable on one hinge half and having a weighting arm which extends parallel to a door hinge axis and projects beyond a door hinge height, at least three, substantially identical abutment rollers having a substantially heart-shaped cardioid cross-section at least along a portion of their height, pivotally supportable next to each other and in a spaced relationship relative to the door hinge axis on the abutment support, and cooperating with the weighting arm of the torsional spring for defining indexing positions in which the door can be retained during its opening movement, and three bearing axles for supporting the abutment rollers on the abutment support and arranged on the abutment support of a distance from each other, which is less than the largest diameter of the cross-section of the abutment rollers.

Abstract: Disclosed is a door hinge assembly for car doors which includes a rotating bar door latch and two hinge wings which pivotably connected to each other by a hinge pin. A first hinge wing may be fastened to the door body and the second hinge wing may be detachably fastened to the door pillar. A catch device for the door latch retarding and securing member, which is disposed on the one hinge wing, is disposed on a lateral wall of the other hinge wing. The second hinge wing is formed by a folded sheet metal part and can be fastened to the door pillar by means of an intermediate part provided with a contact face for the second hinge wing. The intermediate part includes a projection which is aligned perpendicular to the hinge axis receives the hinge pin. The second hinge wing is detachably fastened to the door pillar a second fastener which effects both the connection of the second hinge wing to the intermediate part and provides the common fastening of intermediate part and second hinge wing to the door pillar.
