Description

The The invention relates to a rear door hinge for motor vehicles, with one on a tailgate knock-on door console, for adjusting the rear door between an opening end position and a closed position articulated with an attachable to a vehicle body column console is connected, and a Rastierungseinheit for locking the rear door in at least an intermediate position of the tailgate.

Rear door hinges of the type mentioned above are used in particular in the area of vans, this being a swinging the tailgate up to 270 ° relative to the closed position enable, allowing a simple and comfortable loading and unloading of the cargo space possible is.

In order to prevent damage to the rear doors by contact with possibly located in the pivoting area objects, it is desirable to provide a lock which causes a determination of the rear door in certain opening positions between the closed position and the maximum open position. From the DE 296 16 259 U1 a generic rear door hinge for motor vehicles is known, which has a Rastierungseinheit to solve this problem. However, this rear door hinge has the disadvantage that the door bracket is only about a fixedly arranged on the body pivot axis with the column console is adjustable, which limits the range of movement of the rear door hinge, or only very limited possibilities for arrangement on the vehicle provides when pivoting the tailgate up to 270 ° should be possible. A generic door hinge for a rear revolving door is also from the DE 10 2007 024 572 A1 known.

Of the Invention has for its object to provide a rear door hinge, which allows a particularly comfortable and wide opening of the rear door, at the same time a secure locking in intermediate positions guaranteed shall be.

The Invention solves the task through a hatchback with the features of claim 1. Advantageous developments of the invention are in the dependent claims specified.

According to the invention provides the rear door hinge itself as a double hinge, which is a pivoting of the door console by a total of two formed by the first and second hinge axis Swivel axes allows. This structure ensures in contrast to the known from the prior art generic rear door hinge also in the case of an arrangement of the rear door hinge at a distance of a vehicle corner an opening movement, at the tailgate pivoted up to 270 ° can be. In the opening end position is the tailgate ideally arranged parallel to a vehicle side wall. At the same time guaranteed the Rastierungseinheit a secure locking of the rear door in predetermined Intermediate positions. This will cause an unwanted swinging in the tailgate in an object located in the swivel range, but also too strong Hitting against the vehicle side wall prevented.

By the connection of the door console with the Rastierungseinheit while the pivoting movement of the door console used to drive the Rastierungseinheit, which formed such is that the tailgate in the predetermined intermediate positions between the closed position and the opening end position locked.

The output element is in accordance with this Embodiment in direct operative connection with the intermediate element, so that the pivoting movement of the door bracket from the first intermediate element taken up and used by this to operate the detent unit, or transferred to the Rastierungseinheit can be.

According to a particularly advantageous embodiment, the intermediate element itself forms the Rastierungseinheit, ie is in direct operative connection with the output element. This makes it possible in a complementary manner, the rear door hinge especially small to design. In addition, the number of required components is reduced.

The Output element itself can also be configured in any way be guaranteed is that a movement of the door console in a movement of the intermediate element, or the Rastierungseinheit is converted. It is conceivable, for example, the design of the output element and the first intermediate element as a friction wheel or in the embodiment of the intermediate element as Rastierungseinheit, a corresponding Design of Rastierungseinheit. The output element itself is further according to an embodiment of the invention either integral with the door console formed or by a separate, connectable to the door console component educated. In the case of one-piece training the number of components is reduced in a complementary manner. moreover reduces assembly costs including any necessary alignment of the output element to the door console or the intermediate element.

in the Trap of training as a separate component is reduced due the then simpler design of the door console their production costs. moreover can the output element in shape and size in an optimal way to the existing space and the desired connection to the intermediate element, or adapted to Rastierungseinheit.

This embodiment is characterized by a particularly high reliability the transmission the pivoting movement. In contrast to pure frictional connections guaranteed this embodiment of the inventive rear door hinge a particularly low susceptibility against external influences, for example. Moisture or dirt.

Regarding the embodiment of the Rastierungseinheit has already been the above Place listed, that this can be formed by the first intermediate element, so that on an equally possible Embodiment in which the Rastierungseinheit a separate unit of the rear door hinge forms and is connected to the intermediate element, be waived can. The fundamental Using a separate, connected to the first intermediate element Rastierungseinheit is not excluded and allows possibly the use of standardized detent units.

Also the functional design of the Rastierungseinheit, d. H. the Type of fixing the tailgate in the predetermined intermediate positions is basically free selectable. According to the invention the Rastierungseinheit on a locking marks having detent sleeve, the for locking the tailgate relatively opposite with the locking marks engageable locking elements adjustable is. This embodiment of the Rastierungseinheit, in which the opening positions according to the type, number and arrangement of the locking marks and the locking elements, is characterized by its high reliability and low susceptibility against external influences. To operate the detent unit, it is only necessary either arranged within the Rastierungshülse and at one palm the Rastierungshülse adjacent latching elements relative to the Rastierungshülse or Rastierungshülse across from To adjust the locking elements, wherein the locking elements with at the palm arranged latching marks engage and then lock the tailgate. The choice of adjustment and thus the design of the connection with the output element, directly or indirectly, is basically free selectable and can be done according to the design specifications.

To a particularly advantageous embodiment of the invention is However, output element connected to the Rastierungseinheit such that a pivoting movement of the door console an adjustment of the Rastierungshülse causes, which after a Particularly advantageous embodiment of the invention directly with the Output element is engageable. This embodiment draws characterized by their ease of implementation, wherein the output element are in direct contact with a circumferential surface of the Rastierungshülse can.
