" Description

The invention relates to a motor vehicle door or flap hinge with an additional opening angle, which consists of a first hinge half that can be attached to one and a second hinge half that can be attached to the other door or flap arrangement part and a hinge pin that connects the two together so that they can pivot about an operating pivot axis of the hinge, and one hinge half of which consists of two parts that are connected to one another so that they can pivot about an axis parallel to the operating pivot axis of the hinge and can be connected to one another in at least one mutual orientation by means of a detachable connecting means, in particular a screw bolt.

Motor vehicle door or flap hinges equipped with an additional opening angle, one half of which consists of two parts that can be connected to form a rigid unit by means of a detachable connecting means formed by a screw bolt, are known and used in particular for applications of motor vehicle door or flap hinges in which the door or flap must be adjustable in the opening direction by a larger opening angle than the operationally permitted opening angle of the door or flap in order to facilitate painting of the door or flap joint area of the motor vehicle body. For such motor vehicle door or flap hinge designs, it is generally known and customary to form one half of the hinge from two parts that are connected to one another so that they can pivot about an axis parallel to the hinge operating pivot axis and that lie flat against one another in their connecting position, whereby the two parts of the hinge half can be rigidly connected to one another by means of at least one detachable connecting means that is directed transversely to the hinge axis and is formed by a screw bolt. Such a hinge is essentially connected by a parallel to

The design of one hinge half, which is characterized by its divided design, requires at least approximately a doubling of the material thickness of the hinge half and thus hinders the installation of the hinge in confined spaces. Furthermore, the use of a connecting screw bolt arranged transversely to the hinge axis for the two parts of one hinge half not only makes it more difficult to create a mutual rigid connection between the two parts of one hinge half, but also, in a particularly disadvantageous way, entails the risk of insufficient tightening and thus of the connecting screw bolt coming loose or loosening itself as a result of the vibrations resulting from the operation of the motor vehicle. Such loosening or loosening of the connecting screw bolt ultimately leads to a highly undesirable malfunction of the door or flap linkage.

The invention is therefore based on the object of improving a motor vehicle door or flap hinge of the type described at the beginning, which is provided with an additional opening angle, in such a way that the disadvantages of the known types of such hinges are avoided and that, with low manufacturing costs for the hinge as a whole, the mutual locking of the two parts of one hinge half to eliminate their mutual mobility is made more secure and at the same time the assembly effort for transferring the two parts of one hinge half from one position to the other is simplified or reduced.

This object is essentially achieved according to the invention by a hinge half consisting of a bearing block provided with means for fastening to a door or flap arrangement part and a bracket hinged thereon so as to be pivotable about an axis parallel to the hinge axis, as well as a recess in a position aligned parallel to the hinge axis.

bearing arms projecting beyond the bearing block and at a radial distance from the articulation of the bracket member on the bearing block side, each provided with at least one through-hole for the connecting means, wherein the through-hole arranged in one bearing arm of the bearing block is designed as a smooth-surfaced bore recess and the through-hole arranged in the other bearing arm of the bearing block is designed as a threaded bore.

In conjunction with the design of one part of one hinge half as a bearing block, the through-hole for the connecting means provided in the bracket member forming the other part of one hinge half is formed according to the invention by an elongated hole recess curved concentrically to its bearing block-side articulation and forming an engagement recess or through-hole for the connecting means, which results in the possibility of a continuous adjustment of the size of the mutual adjustment of the two parts of one hinge half and thus also the size of the additional opening angle of the hinge, in such a way that the bracket member can be fixed in different pivoting positions on the bearing block by means of the connecting member.

In an advantageous embodiment, it can be further provided that the curved slotted hole in the bracket member forming the through-hole for the connecting means has different clear widths along its length, so that the screw bolt forming the connecting means can only be screwed into its final connecting position, corresponding to the operational readiness of the hinge, when the bearing block and bracket member are in a predetermined mutual alignment or pivot position.

The curved slotted hole forming the through-hole for the connecting means, in particular formed by a screw bolt

expediently has a larger clear width only in the area of its one end, which is assigned to the mutual zero position of the bearing block and the bracket member, so that a rigid mutual fixing of the bearing block and the bracket member is ensured at least in the operating position of the hinge.

In an extended embodiment, however, it can also be provided that the curved longioch recess in the bracket member forming the through-hole for the connecting means has a larger clear width in the area of its two ends, so that a rigid mutual fixing of the bearing block and bracket member is possible on the one hand in the operating position and on the other hand in the maximum opening angle position of the hinge.

In connection with such a design of the through-hole in the bracket member, according to a further feature of the invention, it is further provided that the screw bolt forming the connecting means is provided with at least one diameter gradation over the length of its shaft part, at a distance from its head, and the clear width of the curved longioch recess forming the through-hole for the connecting means in the region of its two ends and limited to these regions in each case corresponds to the largest diameter of the shaft part of the screw bolt.

In a particularly preferred embodiment, it is provided that the screw bolt forming the connecting means is provided with two consecutive diameter gradations over the length of its shaft part, one of which corresponds to the clear width of the through-hole in the area of its two ends and the other to the clear width of the through-hole in its middle area between its two ends and the third is designed as a threaded pin and has a diameter corresponding to the threaded hole in the other bearing arm of the bearing block.

The design of the two parts of one hinge half, on the one hand as a bearing block with bearing arms projecting beyond the joint connection of both parts in the radial direction and on the other hand as a bracket engaging between the bearing arms of the bearing block, makes it possible to avoid doubling the material thickness of one hinge half and, on the other hand, allows the connecting link to be arranged parallel to the hinge's operating pivot axis and thus easier access to it when the two parts of one hinge half are mutually immobilized. At the same time, this arrangement also results in an easily readable optical display of whether the connecting link is fully driven into its operative position, since this remains visible in every possible operating pivot position of the hinge and a lateral projection of the connecting link beyond one bearing arm of the bearing block represents a noticeable signal of insufficient engagement depth of the connecting link. In addition, in the simplest case, only one of the bearing arms of the bearing block needs to be extended in the radial direction beyond the articulation of the bracket member on the bearing block. Furthermore, the alignment of the connecting means, preferably formed by a screw bolt, parallel to the operating hinge axis also allows the two parts of one hinge half to be fixed in different mutual pivot angle positions, which can be achieved in the simplest case by providing several through-holes for the connecting means in the radial extension of at least one bearing arm of the bearing block along a circular path concentric with the articulation of the bracket member.

In a particularly preferred embodiment comprising the design of the connecting means as a screw bolt, it is provided that the bearing block has two parallel, one end of the bracket member accommodated between them and the bracket-side articulation of the bracket member in the radial direction.
