Description

Technical area

The invention relates to a tailgate hinge stop according to the preamble of claim 1.

State of the art

Such tailgate hinge stops are already known in many forms and configurations and in use.

Object of the invention

The object of the present invention is to overcome the disadvantages of the prior art. In particular, to provide a tailgate hinge stop available, which can be mounted quickly and easily and thus cost-saving, while achieving a good braking effect of the tailgate bracket, which prevents Nachfedern the tailgate latch after opening the tailgate in particular a sedan and thus the risk of injury minimized by a rocking tailgate.

Solution of the task

To achieve the object, the features according to claim 1.

Advantageous embodiments are described in the subclaims.

The inventive tailgate hinge stop is intended for use with a tailgate bracket, as are typically used in a tailgate of a sedan car. In this case, the tailgate bracket moves when opening in a bearing block, which is provided for example in the area obliquely below the parcel shelf.

Since the tailgate bracket is usually spring-loaded, it comes here to back-rocking movements, which must be avoided. This is achieved by a bracket that captures the tailgate latch and intercepts the back-rocking motion.

For this purpose, the bearing block has a quadrangular opening with four walls. But it can also be provided that a triangular opening is used.

In the opening a rubber buffer is provided to catch the forces. The rubber buffer, has adapted to the conditions of the bearing block dimensions so that it can be easily installed in the square opening.

The rubber buffer represents to a U-profile. The U-profile in turn consists of a base, a first leg, and a second leg. The base and the two legs are made of plastic, rubber, or another material absorbable material produced. In this respect, the term rubber in rubber buffer is not an exhaustive meaning, but rather can be regarded as synonymous with other materials also suitable for absorption of force.

The base is fitted fitting in an installed position to an end wall of the quadrangular opening, wherein the side is to be classified as an end wall on which the tailgate bracket strikes when the tailgate is open.

The tailgate bracket should be damped in the opening movement of the tailgate shortly before the end position and show as little as possible springback behavior while running against the end stop.

The main braking effect is generated by two brake ribs, which are supported as part of the rubber buffer in the installed state in the bearing block. For this purpose, the brake ribs are shouldered off by the side walls of the bearing block. This creates a high braking force and unfavorable tolerance of the components can lead to a strong springback behavior.

By two additional outer brake ribs in the installed state outside the bearing blocks, the braking effect should be softer / more muted. The braking force is generated by the cross sections of rubber material. The preferred rubber material is ethylene-propylene-diene rubber (EPDM). The system can thus compensate for more tolerances and thus allow a more harmonious opening of the tailgate.

In the installed state means in the context of this invention, when the rubber buffer is used properly suitable for use in the bearing block.

The first leg is toward a first side wall and the second leg is provided adjacent to a second side wall in the installed position. The first leg forms a first brake rib towards the first side wall. The second leg forms a second brake rib towards the second side wall. As a brake rib here is a structure of a survey and the collection leading recess and to look at the survey after the survey. The brake ribs have proven to be particularly advantageous when catching the tailgate bracket and also when trapping the forces. The first leg and the second leg can each also form further brake ribs.

The rubber buffer forms a first strip of material and a second strip of material, which emerge from the bearing block in the installed state, wherein the first strip of material forms a first outer brake rib toward the second strip of material and the second strip of material forms a second outer brake rib toward the first strip of material. In this case, the rubber buffer together with the described brake ribs, outer brake ribs, locking lugs, latching cylinders etc are integrally formed as parts of the U-shaped rubber buffer.

The base also forms a latching nose, wherein the latching lug can be fixed in a latching safety device of the end wall. This is particularly advantageous for installation, as can be dispensed with any previously existing screw.

The base can also form a further locking lug, wherein the further locking lug can be fixed in a further latching safety device of the end wall. This double protection leads to a particularly tight fit of the rubber buffer in the bearing block.

The locking lug and the further locking lug are each a T-profile, a mushroom profile or a V-profile, which protrude from the base. They stand about centrally from the base, while the other leg of the two legs protrude from the base. The latching safety device and the additional latching safety device are designed, for example, as a slot or a circular recess. However, the shape of the latching safety and the other locking snap safety device is adapted to the shape of the latching lug or the other latching lug, so that other forms come into consideration as long as a einglittene latching lug can not slide out of the latching safety device under normal conditions. The T-profiles, mushroom profiles or V-profiles each form an additional socket, which also serves for better handling. In the case of the T-profiles, these additional sockets are formed on the end side in the installed state against the bearing block.

The first leg also has a first latching cylinder, wherein the first latching cylinder in a first Rastzylinderausnehmung the first side wall can be introduced. The second leg in turn has a second latching cylinder, wherein the second latching cylinder is insertable in a second latching cylinder recess of the second side wall. The locking cylinder are used in addition to the attachment of the legs with the side walls also means that the brake ribs are subjected to a bias and repeatedly occupy their basic position after the release of the tailgate latch.

The legs and / or the base have on the side facing away from the bearing block on a bulge. This bulge is a convex form projecting from the U-profile, which should also give a positive haptic feedback to the user when the tailgate is closed again.

The bearing block is usually made of a metal material, in particular aluminum. However, it is also increasingly the use of plastic into consideration when the requirements of strength are met.

An advantage of the two outer brake ribs is the fact that the retracting tailgate when opening the tailgate initially by the outer brake ribs that are not supported in the installed state of any wall of the bearing block develop a first braking effect and initially soft catch the tailgate bracket. Upon further insertion of the tailgate bracket unfold the brake ribs, which are supported by the walls of the bearing block, a second stronger braking effect and prevent unwanted springback. It is important in this context that the outer brake ribs unfold in the installed state only by the stiffness of the material given support and braking effect and the brake ribs then even develop the final stronger braking effect.
