Description

The The invention relates to a vehicle door with a holding frame and with a disk mounted adjustably on the holding frame. A vehicle door is for example a side door or a tailgate of a motor vehicle.

A at a vehicle door adjustable mounted disc serves primarily by opening in Interior of the motor vehicle for adequate ventilation to make it easier for the driver to communicate to the outside or in an emergency situation an exit or access to the To allow interior. Also, it is possible over an open disc to load or unload the motor vehicle. The latter possibility Especially in the case of a tailgate of a station wagon, vans or Used small car, if little space is available, the rather bulky Tailgate open to expand.

A vehicle door and thus also a tailgate is increasingly the design of the motor vehicle subjected. A vehicle door today often has a complex geometry and has only a small space in the Door body on. As a result, the disc is often no longer sunk in the door body to open become.

When An alternative to a retractable disc in a vehicle door is, for example a manual folding disc known. Disadvantageously, has a manual folding disc, however, a bad ease of use on. When opening it moves away from the user. In addition, the user can at Operating such a hinged rear window slightly dirty become.

It Object of the invention is a vehicle door of the type mentioned specify with an adjustably mounted disc, the disc also simple and space-saving in a complex geometry of the vehicle door to open is.

These Task is for a vehicle door of the aforementioned type according to the invention solved in that the disc over a first and a second link in the manner of a four-link linkage forcibly guided to the holding frame is articulated.

The Invention is based on the consideration, the disc in a forced tour to open in such a way that possible little space is required. The disc can be in this Case even in confined spaces, as they are, for example, in a garage or in a tight parking space, easily opened become. In a further step, the invention proceeds from the consideration, that is such a little space consuming forcibly guided movement can be realized by means of a four-joint linkage. For this the disc is the support frame of the vehicle door via at least a first and a second link articulated movably.

Under a four-joint coupling gear is generally a coupling gear understood, which consists of four articulated gear members, in the simplest case, rods, exists and has exactly one degree of freedom. Over the length of the gear members, i. on the Distance between the joints connecting the gear members, can for a Gear member opposite the other gear member set a desired movement become.

present is used as the first transmission member of the support frame of the vehicle door. He is the first and second as the second and fourth gear member second link articulated. The adjustable fixed disc provides after all the third gear member, which by the two links the Holding frame as the first gear member is articulated movable. The Disc leaves Therefore, compared to the Move holding frame in exactly one specified degree of freedom or adjust.

The Four-joint coupling gear makes it possible to open the disc without stressing a large range of motion. By the obsession is additional a misuse excluded. Next is a desired education the trajectory of the disc by variation of the linkage possible in many areas. additionally allows the forcibly guided Linkage of the disc by means of the four-joint linkage one inexpensive Connection of a motor drive. Because the four-joint coupling gear has a single degree of freedom, it is sufficient only one of the To drive gear members or joints. It does not play any Role at which of the four gear members or at which of the four Joints the drive attacks. In particular for a vehicle door, this flexibility is advantageous, for this additional Motorized drives usually limited space available.

The four-bar linkage mechanism for articulation of the disc to the support frame can in principle be used in a simple design, wherein the disc is hinged by means of the two links to the support frame. Just as well, however, the disc can also be articulated by a plurality of identical executed and arranged in parallel coupling mechanism the holding frame. This increases the overall stability of the disc during the actuation process. It is also possible, only one of the gear members or only one of the handlebars design multiple times to guide the disc mechanically stable.

In an advantageous embodiment of the invention, the first and the second link on such a predetermined length and are spaced apart and rotatably attached to the support frame and to the disc that mounted in a vehicle the disc in a swivel path in the Substantially the contour of the vehicle is guided along. By adjustment the handlebar length and the joint distance it is possible the window of the vehicle door essentially track the contour of the vehicle. In other words, can the disc by means of the four-bar linkage to open lifted out of their gasket and then placed in a combined rotary and swivel path of the outer contour of the Car led along and stored for example on the roof of the vehicle. As well good is also a lateral or a downward, the Contouring contour of the vehicle Swivel path conceivable. The disc remains essentially Aligned parallel to the bodywork along its pivoting path. If the first and second links have a different length, then so This can cause the disc a kinking course of the body tracked become.

advantageously, are the handlebars of the four-bar linkage to the support frame in door orientation pivoted upwards. In this preferred variant the disc is swung up and out of its seal placed on the roof of the vehicle. Especially in tight parking spaces is thereby to the movement of the disc usually above the Vehicle used existing movement space to open the disc. The disc can be easily opened upwards without a retreat or stepping aside is required.

In an expedient embodiment The invention are in a closed position of the disc of the first and the second link partially adjacent to each other or each other. By this configuration, it is possible, the cramped space in a vehicle door optimally exploit. When closing the disc, the Handlebars over- or placed side by side, so that less space in total vehicle door to store the handlebar is required. Depending on room conditions It may be more appropriate, the handlebars next to each other or one above the other to place. Of course it is also possible the handlebars in the closed position both side by side and on top of each other to arrange.

Around the handlebars in a closed position to be able to put the disc in a cavity of the vehicle door, is it required their shape to the given geometrical conditions the vehicle door adapt. Advantageously, this is at least one of the handlebars across from arranged tilted to the rotation axis vertical plane of rotation. at this configuration, the direction of movement of the disc is maintained, only by the oblique arrangement of the handlebar, the two arranged on the handlebar joints with respect to the Rotary plane offset from one another. The or each driver can thereby an oblique Geometry of the vehicle door be adjusted.

Further It is advantageous if one of the handlebars via a ball joint to the Holding frame and / or is coupled to the disc. This allows for one the handlebars a secure support, while the disc by the other handlebars via a swivel further forcibly steered remains.

to Forming the disk-side rotary joint, it is advantageous to glue this to the pane or by means of a bonding agent to fix. These variants represent a safe and easy Connection of the handlebar to the disc.

by virtue of the single degree of freedom of the four-bar linkage, it is sufficient, only to train a handlebar drivable. For this purpose, the motor Drive on the handlebar itself or on a joint associated with it attack. Will the disc over Two four-link coupling gear in the same construction the support frame articulated in parallel, so it is particularly advantageous, respectively to drive a handlebar of the two-four-link coupling gear. One such drive increases the mechanical stability of the articulation system.
